P5W-DH Overclocking issues

I have been trying to overclock my new system with no luck. I am not able to change the fsb and i cant see many of the options such as "AI Tuning" and enabling or disabling C1E and EIST. I have tryed several different bios but I cant seem to get it to work. Any help would be appreciated. (o btw I'm running the board with a E6600, OZC Gamextreme 700W, geforce 7950 GT KO OC)

  1. Hey, having been overclocking my own P5W-DH the past few days I can tell you to follow Wusy's guide for what to disable/enable in the bios.

    EIST (or C1E cant remember which is which) can be disabled in Bios > Advanced > CPU Settings > Virtualisation Technology > Set to Disabled.

    C1E I think is in Bios > Advanced > Jumperfree Config.
    Also in there, set Performance mode to Standard and AI Overclocking to Manual.

    Its also possible EIST has been enabled with either the Asus At Home (bottom of Jumperfree Config > Disabled) or the AI Quiet (disable) feature in Power > Hardware Monitor.

    Once they are all disabled you should be able to adjust voltages and the fsb.
  2. I have AI Quiet set to dissabled
    C1E is dissabled
    EIST doesn't seem to be listed and I can't change Virtualisation Tech, it is in grey and i can't select it
  3. The following is from wusy's OC guide:

    Quote:
    Part1. Tidying Up Your BIOS (not all BIOS may have those options)
    *You must update your BIOS to the latest version before proceeding*

    1. Disable ‘AI Tuning’ for ASUS, ‘C.I.A.2’ for Gigabyte
    2. Set PCI Express (PCIe) frequency @100Mhz (‘Auto’ for DS3/DS4/DQ6)
    3. Set PCI frequency @33Mhz
    4. Disable Hyperpath 3 (for P5W DH only)
    5. Disable any ‘spread spectrum’
    6. Disable Q-Fan (for ASUS only)
    7. Disable ‘Limit CPUID Max to 3’
    8. Disable any overvoltage protection
    9. Disable ‘C1E’
    10. Disable ‘EIST’
    11. Disable Virtualization Technology
    12. Disable No-Execute Memory Protect
    13. Disable any other thing you don’t use
    14. Do not enable any speed enhancements you see


    Hope this helps. :D
  4. I followed wusy's guide and now i flashed to another bios and it seems to be ok. I just dont see "AI Tuning" as an option in my bios.
  5. That's good news. Of course, it's difficult to disable AI Tuning if it's not shown. Hmmm? To which version BIOS did you flash?
  6. Also, the following link is an excellent cooling mod (shown in my sig) for the Asus P5W DH Deluxe, which addresses a problem with some boards topping out around 380Mhz FSB.

    http://www.xtremesystems.org/forums/showthread.php?t=106563

    With part one of this mod, my board is stable up to 414Mhz maximum, so I did not perform the hardware volt mod in part two. Also, I took the mod a step further by adding a 40mm fan to the northbridge heat sink to further reduce the temperatures. The fan is a Cooler Master Blue Ice SLC-S41-U1, and is on the shelf at Comp USA for $10.00. Just discard the heat sink that's boxed with the fan, and use the supplied screws. It's a perfect fit, and the three wire plug will allow the motherboard to monitor the RPM. :D
  7. Topping out at 380? I cant run stable at 355 :P
    Im happy at 340mhz, its enough of an improvement over 266 for me right now seeing as this is my first OC. To get 345 to post I need to bump vcore a notch and even then I ran into stability issues at 355.

    Im not exactly using the full potential of my sexy pc6400 c4 geil ram :/

    So far ive topped out at 338 with the vcore at 1.4 and it runs at 62C on full load. I'm not too confident of raising the vcore more as I think the cpu is running pretty hot as it is.
  9. Don't feel squeamish about pushing up your vCore. Once it becomes apparent that a vCore bump is needed to OC higher, as a rule of thumb, the C2D requires an increase of about .05 volts per 100Mhz.

    For example, if your highest stable clock is 345 x 9 (3.1Ghz) @ 1.35 max stock vCore, then you've got about 300Mhz of OC ceiling remaining, so you should reach 356 x 9 (3.2Ghz) at 1.4 vCore. This varies among E6600's. The goal is not to exceed 1.5 vCore and 50c full load on both cores.

    The cooling mod link explains in detail how vMch (northbridge chipset) affects FSB stability and OC ceiling, but as a second rule of thumb, it requires an increase of .05 vMch per 10Mhz FSB. For a second example, you shouldn't have to increase stock 1.5 vMch to 1.55 until around 370 ~ 380Mhz. This varies among P5W DH's.

    Again, don't feel squeamish about red vMch numbers in BIOS; it's OK to crank it to the max, with the cooling mods installed.

    Hope this helps. Enjoy! :D
  10. You and Sheepish seem to be running pretty close here, but yes, that's too hot for an OC'd system. Are you running the stock cooler? If so, a high end CPU cooler will drop those temps big time.

    Also, not to pick on nVidia, but the 79xx series recirculates hot air inside your case, and doesn't do you any favors when you're trying to keep an OC'd CPU cool. This is exactly why I'm running a 19xx series, because of the dual slot rear exaust cooling solution, which the 8800 series also have. Something to think about. :D
  11. Thanks for the advice CompuTronix. The NB mod is a little extreme for my liking right now. I definately wouldnt want to see temps of 61c although from memory at 1.385 vcore I was hitting 56-57c at load which I wasnt too keen on, although I may have put up with it if I could have gone a good bit past 355fsb. Now ive settled with 340fsb and a notch or two below the recommended 1.37 vcore (for my E6300) im content with load temps of 47c.

    I sort of feel... sad ive finished overclocking already but I wouldnt trust myself to peel off the NB heatsink just yet. I cant afford to screw up :)

    Im actually using the TTBT. This is a friends system that I am overclocking because he doesn't feel comfortable doing it. I came here for help because I'm not very familiar with asus boards but more with DFI. He got the system assembled by the company he bought all the parts from (NCIX) and they put the Big Typhoon on for him. I checked how tight the thumbscrews were and I can still tighten it w/o any problems. I'm not sure if i should tighten it some more or even remount the hole thing.

    What are the temps at stock clock & vCore?
  14. I have the Scythe Ninja and am at 3.2ghz. My system is stable with Orthos but my temps are 62 under load and 50 idle, using Intels TAT. I'm thinking I should reseat my HSF at some point, but from other posts I have been told that my temps are fine. I mean I'm not running my system under load ALL of the time. I am playing Neverwinter Nights 2 now and had TAT running and my temps were in the mid 50's when I reviewed the temp log.

    I did NOT do any of the cooling mods mentioned in this thread. iirc my system at default bios settings was around 30-32 idle.

    I guess I can play with the voltages a bit and see if I can drop my temps. Which voltage would you lower first...ICH, MCH, or vcore?

    Also, is there a way to "save" the bios settings so when you flash the bios you do not have to re-set all of the overclocking settings?
  15. What is your vCore?
  16. Here's everything:
    FSB 356
    memory voltage: 2.1
    vcore 1.425 (at the next lowest notch my system was not stable with FSB of 358. I did not try lowering vcore since I lowered my FSB to 356)
    MCH 1.55
    ICH 1.05
  17. Your settings look fine, but that still doesn't explain high core temps, so how's the ventilation and wiring in the case?
  18. Ventolation is fine. I have the 2 fans near the CPU blowing out.

    I think my cable management could use some help.

    Here's are 2 pictures. Don't cry too loudly.

  19. Follow up...with my case OPEN my temps dropped about 10 degrees. I played with the cables a bit and with the case closed my temps at load (Orthos with the "blend" setting) my temps dropped a few degrees. I am now at 58 under load and 50-51 at idle. I will play with the cables more and see what happens.
  20. you should try pulling out the center drive bay and installing another 120mm fan that really helps with air flow in the P180.
    dont forget about the two screen filters in front of the case.
    they plug up fast.
    Your case looks like a bomb went off :lol:
  21. Well there ya go mickeddie...ya fixed it!!! :D :D :D Seriously though, another lesson on airflow; it's amazing how much neatness counts. Thank you for sharing this with us! :wink:

    Thanks for the reminder about the filters...they were a little dirty.

    Tomorrow I'll power down my machine and re-route some cables.

    Thanks, everyone, for all of your help! I never thought about airflow, nor was it ever mentioned to me before. I figured if the CPU HSF was free of clutter I was fine. I never thought about the cables impeding the inflow vents in the front of the case.

    For those of you that have a p180 and the p5w can you post your pics for me to see what you did with the cables?
  23. Ive cleaned up the clutter after this shot but this will give you an Idea what I did

  24. I'm at 400 x 8 atm (3,2GHz) with my E6600 without doing anything to my mobo except taking off the covers over both bridges :lol:

    My settings are:

    vDimm: 2,1V
    vCore: 1,425V (Intel stock cooler for now, Thermalright Ultra 120 on the way :D )
    vMCH: 1,60V (80mm fan shooting on the NB)
    vICH: 1,05V

    These settings will allow 400 FSB and 3,2 GHz using a multiplier of 8...

    With the Intel stock cooler, 1,475V and vMCH at 1,65 I think, I've been able to do an easy 3,3 GHz (8 x 413) but the temperature were a little high so I'm waiting for my Ultra 120 to arrive :)

    Hope it helps
  25. I cant wait to get my stuff in. UPS likes to hold my stuff in Dallas for an extra day and may it 4 days shipping from the EGG. SO now I wont get my stuff until Tues or Wednesday instead of yesterday. Ill be sure and check back to see how things are going. I gotta lot of work to do.
  26. Nice work! :D

    Is this the CPU cooler you on you E6600 Computronix? I was hoping to not have to buy another one considering this is the one I have.

    http://www.newegg.com/Product/Product.asp?Item=N82E16835118223

    I use the Artic Silver Ceramic Paste instead of AS5.

    WHat do you use to get your temps for CPU and System?

    Thanks for your help

  29. I opened my case and rearranged a lot of the cables and my temps dropped only 1-2 degrees from what they were before.

    Ive heard that speedfan gives the wrong temp reading because it reads the temperature from the wrong sensor and coretemp gives the correct reading. Speedfan gives me a significantly lower temp reading than coretemp.

    Danger, danger!! Speedfan on my system is 15c LOWER than Intel's Thermal Analysis Tool and/or Coretemp.

    Get one of those programs and check your temps ASAP!!!!

    I haver version 4.31 and it says my CPU temp is 33c idle, and TAT and Coretemp say 48-50c.

    has core tempearture monitoring as well.
  36. I just installed the latest beta for Speedfan and my core temp is still the same.
  37. Then i don't know...
  38. Computronix...if you read this, did you take new temps with TAT or Coretemp? I'm curious to see what you get with either of those compared to Speedfan.

    I'm unclear as to how the 15c difference between BIOS/Speedfan versus TAT/Core Temp should be correctly interpreted, and how much additional tolerance should apply in real-world gaming environments with irregular core loads. Still researching. :?


    I've asked that question elsewhere in this forum...Even with games like Oblivion is your system stressed as much as programs like Orthos or Prime95? And if it is, what is the impact on the CPU if you have it at 62c for 2 hours a day and idle the rest, and hibernating when you are not home or sleeping?

    If you find out anything post it please.
  41. turn up your ram voltage - if u bios is missing items
  42. why would you disable q-fan?

    if u using a core2duo the stock intel cooler works great - why waste money?
  43. i might add to that: (this was typed fast and out of order but it works)

    set your mch voltage to one from the bottom 1.6v, set your ram voltage to 2.1 set your c2d cpu voltage to 1.4v-1.45v - or turn up the volts until the temp rises 1-3 degrees in bios from the hardware monitor - then turn it down a notch.

    you may want to set the fsb to 1.3v and south bridge to 1.05 - less auto is better!

    set pci to 33.3 and pcix to 90
    set your fsb to 375 and check the cpu after you run it brand new for 5 mins on auto. tune it 410-425 - depends on many factors. max mch for max fsb


    o ya- check out my how to build a water cooled pc guide:
    http://forumz.tomshardware.com/hardware/build-liquid-cooled-pc-PC-ftopict216766.html


    then set your latencys - no mem test needed - play with them (latencys and mem voltage) to you get the fastest boot and fast loading of start up

    physically test your memory for heat - if its too hot turn down the volts - cool maybe you can add more?

    limit your start up to antivirus AVG 7.5 free, antispyware, ai booster and ai probe - use/ load spysweeper or similar to block start up pograms

    when u get the fastest cleanest boot - your set

    o ya - turn off ai for windows install - do not oc until after - better yet oc in bios before windows burn in the system with the hardware monitor up - turn off the oc then load windows in auto-bios no ai.

    turn off boot from 2nd controller in "chipset" in bios - buy 2-3 hdd and turn on the raid in main page and make a floppy from another computer - remember to hit f6!

    do not forget to set up the raid - hold the control and tap on I - i think! raid 0 64k size - unless your a store or something make it smaller!

    if your raid drivers fail - load again load again! if still fails make a new disc! still fails check your memory!

    set boot order to cd first to load windows then set it hdd,cd,floppy

    crank up the oc! if the window screen crashes lower the fsb or crank up the mem volts!

    if u get logo error during windows - scrape it, if your on auto with no oc - then reduce the memory speed - it might work!

  45. This is driving me bonkers. I've got a P5W-DH Deluxe and can't seem to get the FSB faster than 300MHZ. From what I read here and elsewhere I should be able to get to 333MHZ or even higher. - 333 is my target.

    Here are my specs:
    C2D X6800 - currently at 3.3GHZ
    Zalman 9500
    P5W DH
    2GB Corsair 8500C5 (Running at 1000MHZ 5-5-5-15-5)
    EVGA 8800 GTX
    Thermaltake Case - 3 fans
    Thermaltake 750W PSU

    Settings:
    FSB 300
    Vcore - 1.4 (have had up to 1.425 no difference - do I go higher?)
    vMch - 1.55
    vMem -2.1

    Temps are 41C idle, 52C heavy load - I haven't been able to get it hotter than 54C.

    If I set FSB to 333 and adjust memory timings to keep memory speed around 1GHZ, it boots and runs memtest all day long. Prime 95 fails though after awhile. vCore reports 1.39 or so in CPUZ...
    Can I make this faster?
  46. Sounds like your chipset has a "speed bump" or unstable clock region which prevents the FSB from stepping to the next level. Since you have an unlocked multiplier, you can try experimenting with dropping to x10 or x 9 to reach a higher FSB and OC. My P5W DH is at 411 x 9 for 3.7 Ghz.

    Hope this helps. 8)
  47. turn up the mch voltage

    you sure its not the ram - turn down the ram speed and then oc
    then turn up the ram speed
