E6600 overclocking badly..

Quite dissapointed with OC results..

I am quite a newbie when it comes to overclocking, but I did expect greater things from my E6600, first of all, here is my rig:

Windows XP Pro
C2D E6600
Thermalright Ultra-120
4GB PC2-6400
ATI X1900XT
ENERMAX 535W
320GB HDD
ASUS P5W DELUXE WIFI

Temps @ 3.1Ghz -
Idle -
CPU: 26
CORE 0: 35
CORE 1: 37

Load (prime 95)
CPU: 33
CORE 0: 42
CORE 1: 42

It's running prime 95 Small FFT's test as I type this and seems fine at the moment, but haven't been running for long. I will be watching a few films in my room and letting this run, while checking to see how it goes every so often.


I just started overclocking and got myself up to 3.1Ghz on the E6600, vcore - 1.35V, all other voltages are on auto, all power savings / unnecesary things all disabled. PCI-E Frequency - 100Mhz, PCI Clock Synchronization -33.33Mhz, these are basically all what I was told to set. Now, my RAM is running in 1:1, so is currently at 345.5Mhz, which later on I'll definetely want to get back up to 400Mhz+, and the timings are extremely bad at the moment, but I'll fix those later: 5-6-6-18 (btw, where do I find the settings in the bios to adjust timings?)
Anything past 3.1Ghz and my system just wont POST, so I can't even test if it would work, it will just keep rebooting itself until I change it lower and I have found that this is the highest I can get to without it not POSTing.
OK, I was wondering what I need to do to get my overclock higher, as I have heard many people reaching MUCH higher with just stock COOLING! and originally I was hoping to get up to and even beyond 3.6Ghz with a 1:1 from my 400Mhz RAM (PC2-6400). What do I have to do to increase my overclock without it not POSTing? I know I'm quite a newbie to this, is it just me being a newb or is this the highest physical overclock I can reach? (I doubt this though) I'm actually guessing it's most likely that because all my voltages apart from vcore are on auto and not set well?
So, please help me reach a good overclock speed with my E6600 and my RAM, I'll greatly appreciate any help/tips or anything.

  1. I'm running the same MB and C2D. Check my sig. So what do you need to work on next? In a word, Vcore. Read the Overclocking section in my Temp Guide. You've got about 300 Mhz left to go before you max out your rig.

    Understand there are no solid state devices 100% identical. Every piece of silicon is unique, and as such, has different properties of electronics which include resistance, capacitance, inductance, impedance, and transconductance. Although two consecutive serial number CPU's from the same fabrication, with the same stepping codes may appear identical, they're yielded from different location on the silicon wafer from which they're manufactured, and like diamonds, each has it's own unique flaws.

    Even though their dynamic operational characteristics may be very similar, no two CPU's will overclock to exactly the same stable maximum speed, at the same Vcore, at the same temperature. Additionally, in a muli Core processor, one Core will always become unstable before another. The overclock ceiling for the E6600 is typically 3.4 to 3.6 Ghz at 1.5 Vcore with top-of-the-line air cooling.

    It's impossible to predict at what clock speed the Cores you have will become unstable as you increase Vcore, but don't feel apprehensive about increasing Vcore when overclocking a 6600. These processors are quite robust, however, do not exceed 55c Tcase / 70c Tjunction during Load testing with Orthos, and 60c Tcase / 75c Tjunction with TAT.


    Hope this helps,

  2. Thanks, but I don't really understand it, I'm no good with all this tech stuff. :P If I was to go for 3.6Ghz, what Vcore do you reckon I will need to use? Also, will it work? As last time I tried it with my Vcore as auto and it wouldn't POST.
    Also, should I keep my rig testing for longer or try and overclock further?
  3. Wow.. I just tried the 5 following set ups and none of them would even POST, let a lone start up windows ready for testing..

    I started off with a long shot;
    400FSB
    800Mhz RAM
    5-5-5-12
    2.1V RAM
    1.4V vCore

    Then I tried the following:
    375FSB
    800Mhz RAM
    5-5-5-12
    2.1V RAM
    1.4V vCore

    365FSB
    800Mhz RAM
    5-5-5-15
    2.1V RAM
    1.4V vCore

    350FSB 800Mhz RAM
    5-5-5-15
    2.1V RAM
    1.4V vCore

    I just got fed up after these and went back to what I was on before, however I did change the RAM timings, upped the vCore and the RAM voltage, I'm stuck for ideas now.. What do I do? You said I could get at least 300Mhz more, what's going on then? :(

    345FSB
    5-5-5-12
    2.1V RAM
    1.4 vCore

    I'm currently running the FFT tester as we speak still..
  4. I was editing when you posted, so read my text above. Never use auto settings when overclocking. Manual settings only. Keep in mind that overclocking is best approached methodically and meticulously, similarily to a scientist conducting a controlled experiment. Keep track of your steps and take notes. Only make one change at a time, then re-test. It's extremely time consuming, so be prepared to invest dozens of hours in tweaking and testing, because there's no quick and dirty way to achieve your highest stable overclock, however, your efforts will be well worth it in the knowledge, understanding and experience you gain, as you learn which tweaks produce which results. Don't take shortcuts by making several changes at once, because you'll never know which CPU or memory or motherboard tweaks resulted in a stable overclock, and you'll never understand what you're doing. If you get stuck, read...read...read. At some point you'll need to tweak Vmch (Northbridge) to increase your FSB and remain stable.

    Have you read graysky's Overclocking Guide? http://www.tomshardware.com/forum/240001-29-howto-overclock-quads-duals-guide

    Also, I wrote "You've got about 300 Mhz left to go before you max out your rig." The operative word here is MAX, not AT LEAST! Understand that your particular E6600 may not have the potential to reach 3.6 Ghz, and this is likely, since you're unstable above 3.1 Ghz at 1.35 Vcore. I predict that you'll max out at 3.4 Ghz, but I hope that you can prove me wrong. You'll need 1.5 Vcore, and at that much Voltage, you'll have a hard time trying to maintain safe temperatures, even at 22c Ambient. Re-read the Overclocking section in my Guide!

    Comp :sol:
  5. Thanks for the help! I really do appreciate the time your taken to share some of your knowledge with me.
    What about the other temperatures apart from RAM/vCore? Shall I keep them on auto as I have no idea what they do / control?
    Is the RAM voltage completely seperate from the other voltages, for example if I can't run 800Mhz @ 5-5-5-12 at 2.1V RAM, does this mean I'll never be able to run that unless I put the voltage up? Seeing as my maximum is 2.2V however, I don't think it's a good idea! How do I make my RAM 800Mhz if it doesn't come up in the list due to the clock speed not being 1:1?
    Finally, how long do you think I should typically test each time I find a stable speed and what increments do you find best when you are pushing the clocks up?

    Again I want to thank you for the help!
  6. I just tried another few combos and they all FAILED to POST, apart from the last one which is basically what I had before, I am now testing this one though:

    380FSB
    570Mhz RAM
    2.1V RAM
    1.475 vCore

    370FSB
    570Mhz RAM
    2.1V RAM
    1.475 vCore

    360FSB
    570Mhz RAM
    2.1V RAM
    1.475 vCore

    They all failed, this is the one I'm running on now:
    350FSB (+5 from before)
    700Mhz RAM (+10 from before)
    5-5-5-12
    2.1V RAM
    1.45 vCore

    I really am stuck now..
  7. One thing at a time. Downclock the RAM to remove it from the equation of Variables, (so it's not a stability issue), and focus on working with the CPU Vcore and Motherboard Vmch. Again, please read graysky's Overclocking Guide. You must be patient, and take a methodical approach if you expect to produce favorable results.

  8. computronix...whats ur temps on ur e6600 at 3.7?

    is it cpu-z verified? and whats ur settings for that oc. im at 3.3 on my e6600 with msi-neofr2(stock voltages). my ram is whats holding me back but posting ur settings may help a few people. namely crumble :p
  9. Perham, what is the stock voltage for vCore?

    I've had this running overnight and it's stable, here are the settings I'm using at the moment:
    345x9 = 3105Mhz
    864Mhz RAM
    5-5-5-12
    2.15V RAM
    1.4V vCore

    Super PI: 16s

    Here is a picture of a few tests I ran and my temperatures idle:
    http://i202.photobucket.com/albums/aa158/crumble114/overclocking/untitled-2.jpg

    I am now really stuck on what to try next, do I put the RAM speed and timings down or keep them the same? Anything that I go to above 345FSB wont even POST for me, is this because I'm not giving it enough voltage? Should I set the voltages at auto to different things? (all apart from RAM/vCore are at auto) Someone give me a hint. :)
  10. I would try unlinking your ram to see if that's what's holding you back.
    By the way, what are you using for cooling?
  11. Hey crumble I have the exact same issue. I can't get past ~3.1 GHz as well.

    I was thinking it was my chipset: Nvidia nForce 590 Intel edition.

    I am going to try lowering my timings and increase the Northbridge voltage to see what happens.

    Here are my specs:

    Intel Core 2 Duo E6600 @ 3.0 GHz @ stock voltage.
    ASUS P5N32-SLI Premium
    OCZ Platinum DDR2-800 RAM 5-4-5-15 (I think)
    WD Raptor 150 GB
    Sapphire Radeon X800 Pro
    SB X-Fi Fatal1ty
    Zalman CNPS9700 with zalman STG-1 compound.


    That's probably more than you need to know about my setup.

    What does unlinking my RAM mean? I'm using a Thermalright Ultra-120 heatsink with a Zalman ZM-F3 on it. I also have 1X 90mm Zalman ZM-F2, another ZM-F3 exhaust fan and a stock fan from my case cooling the HDD. I have a Soprano case, can't remember the make.
  13. Theres some settings in your bios that will let you run the ram at a slower speed. Instead of running 1:1, try running at (someone correct me on this) 2:3 or something like that (i forget the numbers off the top of my head).

    Some people would have you believe that there is something magical about a 1:1 ratio, but for finding out your max OC, I don't see any problem with it and it should give your RAM some more breathing room.

    BTW, I missed your RAMS default specs, can you list that.
  14. I have 2GB "OCZ DDR2 PC2-6400 Special Ops Edition" which is at 5-5-5-12, link to it is here:
    http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_6400_special_ops_edition
    and the other 2GB is of "Corsair 2GB DDR2 XMS2-6400C5", which is the same timings as the OCZ. They both have a max voltage of 2.2V IIRC.
  15. Why does my multiplier keep changing from x9 to x6 for no reason sometimes, all my power saving options are off.
  16. either you missed an option, or its thermal throttling
  17. Do you think this is a good idea to try next:
    375FSB
    750Mhz RAM
    6-6-6-15 RAM timings
    2.1V RAM (is this enough?)
    1.45V vCore (is this enough?)

    I also need some suggestions on what to set the other voltage settings to as I don't even know what they actually do, could someone tell me/help me out here?
    Thanks.

    I found this set of results on another overclocking forum and they looked quite feesible, so I will definitely try something along the lines of:

    Would these voltages be OK do you think for my system however?
  22. "The Northbridge Vcore has the biggest impact on overclocking success." When I was about maxxed out on my OC I upped the NB Vcore to 1.55 and was able to get a higher OC. I'm at 400 fsb now but have tested using Orthos at 467 fsb and pasted, but my temps weren't to good. Its my PC case thats bad for cooling so I am going to get a better case so I can run at 467x8 = 3.7GHz. Don't go to the highest NB Vcore setting without a 60mm fan on top of your NB.

    Asus P5B Deluxe:
    CPU Vcore 1.54v
    NB Vcore 1.55v
    FSB termination voltage 1.4
  23. Well, I don't have a fan on it as such, but I have fans all around it, one 90mm on the side of the case, that's mostly going into the Thermalright Ultra-120 and an exhaust 120mm just to the side of the Ultra-120, however doesn't the P5W DELUXE have special cooling system for the NB? If I do infact have too bad cooling to put the NB voltage up, where abouts would you say I put it?

    Thanks for the help system lord, a few more questions for you if you don't mind:
    -What heatsink are you using and what are your temperatures idle/load? (if you don't mind)
    -Should I leave the other voltages and just focus on these 3 plus the RAM voltage then?
  24. crumble114, I've been traveling this week, but I'll be back aboard my boat this evening, so if you'll be patient a bit longer, I will give you my settings for the Asus P5W DH Deluxe / E6600 at different FSB / CPU / Memory clock settings. During the many dozens of hours of stability testing I've done while overclocking this MB / CPU / BIOS combination on several different high end overclocked rigs I've built, I've carefully documented settings and performance benchmarks. Understand that this Motherboard uses the 975X Northbridge / ICH7 Southbridge Chipsets, so if you attempt to use settings from other Motherboard / Chipset / BIOS combinations, they are invalid. As I said in an earlier post, not all CPU's are created equal, and although 3.4 to 3.6 Ghz is typical for the E6600, some chips just won't get there, so "typical" doesn't mean that your chip came with any gaurantee to even reach 3.4 Ghz. You're dealing with nano electronics, and no two pieces of silicon are identical.

    Also, keep in mind that some C2D's are unresponsive to certain FSB / Memory strapping combinations, and manifest this unresponsive behavior as a virtual overclocking "wall" which can "sometimes" only be overcome by reducing the multiplier to 8, and increasing the FSB (Front Side Bus) clock. The P5W DH Deluxe is typically an excellent match for the E6600, however, it lacks the ability to reach the higher FSB settings of the 965 or the newer P35 Chipsets. The P5W DH Deluxe is known to seldom reach stable FSB settings above 425 Mhz. My particular board max's out at ~ 417 Mhz, so at 3.7 Ghz (9 X 411), FSB stability is dictated by a normal Ambient temperatue of 22c which affects all temperatures inside the computer case, an MCH (Northbridge) voltage setting of 1.75, and an FSB Termination voltage of 1.4, if I recall correctly.

    As systemlord pointed out, FSB cooling is critical for stability at high FSB / VMCH settings, so in my sig you see "Cooling Mods", which means I have carefully removed the rediculous (but decorative) shiny heat sinc covers from the Northbridge and Southbridge heat sincs, and attached a 40mm Cooler Master fan to the Northbridge. This is available as a boxed fan / heat sinc kit, which is on the shelf at Comp USA for ~ $10.00. I simply discarded the heat sinc from the kit, and used the fan and the screws included to attach the fan. It's a perfect fit, and the 3 wire connector allows the fan RPM to be monitored by utility software. I strongly recommend performing this easy little modification on this Motherboard, since I've been able to prove that it enhanced my FSB stability, and extended the clock range while requiring less voltage.

    Hope this helps,

    Ask as many questions as you wish. What I did was buy a 40-60mm fan and some doublesided sticky tape to make the fan stick right on the NB heatsink. You can also stand it up and have it blowing into the side of the NB. I'm using the Tuniq Tower 120 which is just as good as yours, really the one you have is a little better than mine.

    My OC is 3.6GHz 400 fsb with a 9x multiplier, my temps at idle are between 26-29c & fully stressed are 54c Tcase and 65 Tjunction or core temp. My cooling at stock were 17c idle & stressed were 28c. When I get a better case I will push 467x8 fsb = 3.7GHz as I have already tested it using Orthos for 24 hours. However I have lapped both my CPU & TT 120, thats why I'm running a little cooler than most.

    As for voltages lets wait till you get to 400 fsb, so for now leave it where it is. What are your voltages for FSB volts, NB volts and CPU Vcore at? Heres what lapping looks like when your done.>>

  26. Thanks alot of the help systemlord and CompuTronix, that would be great if you don't mind CompuTronix!
    Ok here are my OC settings at the moment and they are running fine and stable, tested over 16 hours, no errors and good temperatures IMO.
    E6600 @ 3109Mhz (345 FSB)
    RAM @ 864Mhz (5-5-5-12)
    RAM voltage = 2.15V
    CPU voltage = 1.4vCore
    All the other voltages are set on AUTO as at the time I had no idea what they did.

    I was thinking that this is what I'll most likely be trying for my next attempt:
    Run next:
    400FSB (or 380 if 400 wont POST)
    RAM @ 760Mhz (6-6-6-15) (i'm guessing this is OK, as you said, I should try relaxing the timings/speed for RAM while i deal with the CPU OC)
    RAM voltage = 2.1V (i'm guessing this is OK)
    CPU voltage = 1.525Vcore (too much/too little in your opinion?)
    FSB termination = 1.4V (have seen many people with the same value as this one while overclocking the E6600, this ok?)
    NB Vcore = ???? (absoloutely no idea about this one at the moment, 1.4/1.5? what do you reckon?)
    Again, thanks for the patience with me! :)

    @CompuTronix, I wouldn't be able to buy any more components for my computer for a few months now as I tend to buy a few at a time and I just recently bought a load, so I doubt my parents would allow it, great suggestion though and I will definitely look into it at a later time. (parents FTL :P)
  27. You can try 1.65 or 1.75 for a Northbridge voltage setting, but I do not recommend pushing it to the max at 1.85, even with the cooling mod.

    Comp :sol:
  28. Sigh, I just tried a few more OC settings and none of them would post so I'm back to my original settings... <_<

    This is what I tried:

    380FSB
    760Mhz RAM @ 6-6-6-12
    RAMV = 2.1V
    Vcore = 1.5V
    FSB termination = 1.4V
    MCH = 1.65V (i'm guessing this is the NB voltage as there isn't one that says NB, am i correct?)

    This failed to post, so I tried the same, but upped the Vcore to 1.55V, still no POST.

    I then tried dropping the FSB to 365FSB:

    365FSB
    730 Mhz @ 6-6-6-12
    RAMV = 2.15V
    vCore = 1.525V
    FSB term = 1.4V
    MCH = 1.65V

    Still no posting! Angry and annoyed, I tried the following:

    355 FSB
    710Mhz @ 6-6-6-12
    RAMV = 2.15V
    vCore = 1.525V
    FSB = 1.4V
    MCH = 1.65

    Still wouldn't bloody POST, I can't seem to get anywhere above what I have it at at the moment!

  29. It seems that you have hit what some would call a FSB hole or bump. Try lowering you multiplier to 8 and try upping the FSB to 400 and if it don't post try shooting past 400 to maybe 425 FSB, you can still get 3.6GHz at 450x8 = 3.6GHz. If anything is stopping you from going any higher in FSB I'd guess its the motherboard because the 975's have been known to not quite go as high in FSB as the P965 chipset which is to be expected. That right there is the main reason I purchased the P965 in the first place.

    Sometimes setting a lower multiplier allows for a higher FSB, in this case its true for me. You've heard of those E6300/E6400's overclocking to insane FSB speeds and having high FSB of 500+ with lower multipliers, this is because the E6400's don't have an 8 or 9x multiplier. So try giving it a high FSB with a lower 7x or 8x multiplier and see if that works.
  30. I will definitely have to try that out later, but first I am going to make sure I cannot reach higher with the 9 multiplier.
    A few questions then; is there any disadvantages to running at a lower multiplier instead of a higher one? Will I just keep the same voltages / settings as before, but just change the multiplier? Lastly, how would I go about changing the multiplier? IIRC, when I checked it last time it was locked.
    Thanks.

    Your multiplier is locked from going any higher than the stock of 9x, but you can lower it to 8x 7x 6x. You will not suffer any performance loss by lowering your multiplier, its just a math game. In my mobo's bios its called Ratio Cmos settings. The lower multipliers are there for just this reason because some mobo can go very high in FSB speeds but only with a lower multiplier. Imagine getting a 540 FSB with a 9x multiplier thats 4.8GHz, only with the most expensive of water cooling.
  32. Thanks for the help, I'll try this out soon and report back with my results..
  33. crumble114, which BIOS release does your Motherboard have and what version is your MB? If your BIOS is an earlier release, 1305 for example, then it will not allow you to reduce the multiplier. Watch the screen when the system is rebooting to identify BIOS. If you have the earlier version of this MB, it will only allow you to increase the MCH Chipset Voltage from 1.5 to 1.65 (in 0.05 volt increments), while newer versions will allow 1.55 to 1.85 (in 0.1 volt increments) which determines how high you can overclock the FSB.

    Based upon what you've written so far, I suspect you have the earlier board with earlier BIOS, which means that even if you flash the BIOS to the latest release, (which will allow you to reduce the multiplier to 8, 7 or 6), you'll still be more FSB limited by a maximum Vmch of 1.65, (due to having the earlier board), so you'll be unable to reach an FSB of 425 Mhz X 8, for 3.4 Ghz. Also, C5 memory is a poor selection for overclocking, and since you're not running Vista, 4 GB is pointless since XP Pro will not read more than ~ 3 GB, and 4 Gb is known to cause stability problems on many Motherboards, including yours, unless you're running XP 64 or Vista.

    I would recommend that you eBay or get a refund on the 4 X 1 Gb modules and buy 2 X 1 Gb C4 modules, and buy the $10.00 fan kit for cooling the Northbridge. XP Pro runs best on 2 GB, so please install 2 memory modules only while we continue troubleshooting. The following BIOS settings for your Asus P5W DH Deluxe WiFi are those which affect or dertermine overclocking. We will begin at 3.2 Ghz and work our way up.

    The other BIOS settings have no bearing on overclocking or temperatures, however, it's important to familiarize yourself with all the features in BIOS, so learn what you can from by studying the manual, and whatever you don't understand can be found from on-line resources such as Wikipedia.

    Let me know what you find regaring your BIOS release, Motherboard version (MCH Chipset Voltage), differences in BIOS settings, and overclocking results.

    Hope this helps,

  34. Wow, brilliant help CompuTronix, thanks!
    Ok, here we go:
    My BIOS version is the newest one out, which is version 2301 I believe, as I just flashed my BIOS with the newest version last week or so. I have no idea which motherboard version I have, but if I recall correctly, the MCH voltages I can choose go up in increments of 0.15V, but I'll have to check this out later to confirm it.
    I'll definitely look into getting a refund on my 4GB C5 as I now know it was a stupid idea to do so and I'll try and grab some C4 instead. However, if the company I got the RAM from (overclockers) will not let me return the RAM for a full refund, I wont be bothering with ebay or trying to sell it elsewhere as I don't really have the time to do it, nor the patience. :P
    I should be able to get a refund on the 2GB I recently purchased, but the other 2GB I got on the 2nd September 2006, and seeing as it was double the price RAM is today, I doubt I will be getting one for that set.
    However, once I've found out for sure, I will post back with more details.
  35. OK, I've just found out that I will be unable to return my RAM, so that's that for that problem I'm afraid. Secondly, I just checked my BIOS and the values I can change on the MCH voltage are as follows: 1.55/1.65/1.75/1.85V and the multiplier is greyed out, however it says that it is unlocked which must mean that I can infact change it?
  36. You can not increase the multiplier, but you can decrease it, ONLY if SpeedStep is disabled. Don't get stuck on the multiplier for now. Please follow through with confirming the BIOS settings, particularily Hyper Path 3.

  37. "Peg Link mode-faster"

    Hay CompuTronix I have a question for you, is there any danger of damage to my 7800GTX if I increase my Peg link mode to = faster? Right now its at normal and I have heard people say (in guides to overclocking) that changing this setting can give you considerable performance increase, but then say, "for the brave ones". Thanks for you help. :)
  38. I haven't encountered any isses running either ATI 1k / 2k, or nVidia 7k / 8k based cards with PCI Express Graphics (PEG) Link Mode in "Faster".
  39. I have checked through the BIOS and all the settings are as you asked me to set.

    Did you notice a performance increase?
  41. systemlord, as I recall, the performance increase was only a few percent as indicated by various 3DMark results, but I'll gratefully take whatever I can get.

    , I take it from the brevity of your response that:

    (A) Your rig won't boot at the above settings for 3.2 Ghz.

    (B) You're still unable to reduce the multiplier to 8.

    (C) You've installed only two 1 Gb memory modules.

    Any other observations?

  42. How's the overclock coming along? Any successes?

    Wow.. I just tried the 5 following set ups and none of them would even POST, let a lone start up windows ready for testing..

    I started off with a long shot;
    400FSB
    800Mhz RAM
    5-5-5-12
    2.1V RAM
    1.4V vCore

    Then I tried the following:
    375FSB
    800Mhz RAM
    5-5-5-12
    2.1V RAM
    1.4V vCore

    365FSB
    800Mhz RAM
    5-5-5-15
    2.1V RAM
    1.4V vCore

    350FSB 800Mhz RAM
    5-5-5-15
    2.1V RAM
    1.4V vCore

    I just got fed up after these and went back to what I was on before, however I did change the RAM timings, upped the vCore and the RAM voltage, I'm stuck for ideas now.. What do I do? You said I could get at least 300Mhz more, what's going on then? :(

    345FSB
    5-5-5-12
    2.1V RAM
    1.4 vCore

    I'm currently running the FFT tester as we speak still..



    i have the e6600, i also have tryed all those settings in the beginning and had probs booting... think i got to 3.0ghz when i was changing voltages with the fsb.... finally i realized i didnt need to touch the memory volts or vcore as thats what was messing things up... now im running stable at 3.6 ghz and all the volts on auto... my idle is 41c and load 45-46c.. also my memory is at stock speed 677mhz with volts on auto.. everythings stable as hell as i play high demanding games.. i been tryin different settings for over a week and just yesterday found stability in only upping the fsb to 1600mhz and touching nothing else. althought i cant go above 1666mhz fsb or i wont boot... so i guess that means more volts or memory upping. But try leaving everything on auto and only upping your fsb, bump it up a little at a time. try 1222mhz, if sucesfful try 1333, then 1444,1555 untill you reach 1600 if possible as thats what i did.

    before you take my advice keep in mind that i dont know your set up, what are your specs?.I have a asus p5n-e sli motherboard.In the beginning i couldnt make 3.0ghz untill i updated my motherboards bios.. then i was able to overclock my a** off... always make sure you flash your bios to the latest bios. Also i have a very good custom air/fan cooling system so that plays a huge roll also...

    Hope this info was helpfull and you achieve your desired speeds:)
  44. update to my last post..well. i finally decided to add volts since i was hesitant about heat issiues and go for 3.8ghz and it worked!. havent hung once on boot... i set my fbs to 1695, vcore to 1.53, changed my ram from 677 to 800mhz and set my rams volts to 2.13..i did a stability test it i hit max load 54c and i idle at 43c.. i cant belive how good thie e6600 can OC. 4.0ghz is my next goal but im do some more reading 1st :sol:
