Well I'm back at it again.
First my hardware:
Intel E6600 2.4Ghz Core2Duo,
ThermalTake SI-128 HSF,
Gigabyte 965P-DQ6 Mobo, F7 BIOS Version,
OCZ Gold PC6400/DDR2-800 2GB (5-5-5-12),
ULTRA 500W PSU, ATI AIW X1900 256MB,
Pioneer 16x Burner, 750GB SATA2 HD's.

This time I have installed the SI-128 Thermaltake CPU cooler using Silver Arctic 5 lube.
My hardware is listed at the bottom of this page.
I can't get my CPU to OC higher than 3.18GHZ without it becoming unstable or rebooting on me when I commence doing something other than bringing up Firefox & typing this up.
My rig is hanging out at between 50C-53C using the Intel T.A.T., In the background working is, McAfee 2006, Yahoo Messenger, Spyware Doc, & my FTP server app.
I use my system mainly for flight sims & video editing.
I got rid of the stock CPU cooler.

I've tried a few different settings & these seem to stick up to this speed.
I've tried changing the CPU Clock Ratio to 8x. & the CPU Host Frequency (Mhz) set upto 455.
I've tried setting the CPU OverVoltage Control to 1.32500-1.40000. No success.

Currently my PC is stable so far using these settings below @ 3.18Ghz:

Try reducing the system memory multiplier to 2.0 and bump your vCore in small increments until you get stability.

I'll be trying that tonite. Thanks.

Well, I took your advice. I did manage to get it to run up to 3.24Ghz with your suggestions.
But, I can't get it to go higher than 3.24Ghz now without it rebooting on me when I do anything other than type this in the forum. My temp readings are now 57C. The changes I made are now in BOLD RED.

Probably need more vCore. So long as your temps stay within reason you can continue to increase voltage - personally I would not go over 1.5 max but you shouldn't need to go that high.
November 28, 2006 11:59:53 AM

Try this:

8x427 (3.4ghz) v.core 1.381v
mem divider 1:1 (854mhz) 5.5.5.15 2.25v-2.3v
v.mch 1.65v (+0.45v)
v.fsb 1.4v (+0.2v)

You shouldn't worry to raise your chipset voltage bcs DQ6 cooling pipes will take care its chipset temps, just make sure your case have a good airflow.

If you want to oc to 3.6ghz+, you must replace your hsf with Tuniq Tower 120. Even my Zalman 9500 has prevented my E6600 to clock more than 3.6ghz (1.475v).

Huh!!??
Doh!! My bad. Did I forget to mention that I'm a nOObie at this? Talk to me like I'm a 3rd grade child. Hold my hand & help me cross the street.

ok, I understood:
"8x" must be for the: CPU Clock Ratio option,
"427" must be for the: CPU Host Frequency (Mhz) option,
"v.core 1.381v" is for: CPU OverVoltage Control option,
"mem divider 1:1 (854mhz)" is the grayed out option & just for informational purposes,
"5.5.5.15" are the numbers I put in under the DRAM Timing section,
"2.25v-2.3v", where does this get plugged into :?: ,
"v.mch 1.65v (+0.45v)", where does this get plugged into :?: ,
"v.fsb 1.4v (+0.2v)", where does this get plugged into :?: ,

2.2V-2.3V is for the memory voltage.

The others are for the chipset and the front side bus.
Not knowing what is your motherboard I can't help you, but it's usually under the advanced / jumperfree configuration.

Huh, it was in your sig :oops: 
Lazy me!

Page 45

Dimm overvoltage = 2.25-2.3
v.mch = MCH OverVoltage
v.fsb = FSB overvoltage

*Disclamer* these voltage seem good/resonable, but I didn't recommand them
But don't worry that's not nearly enough to do damage

Well, I took your advice & made the changes. It seems like this mobo doesn't like anything higher than 3.25Ghz. It just goes into a rebooting state or the system will boot without any video output & I have to open up the case to clear the CMOS to clear up this hickup. The video doesn't come up when I mess around with the "(G)MCH OverVoltage Control" option when setting it to anything other than the "NORMAL" option.
My temp readings are hovering @ around 55C when idle.

bump!!!

Anyone with similar hardware having problems gettin over 3.25Ghz when OCing?
Thanks.
December 1, 2006 8:49:06 AM

I have 4 PC's running BOINC Projects 24/7 with the DQ6 Motherboard & E6600 CPU, all 4 of them are Air Cooled with the Thermaltake Big Typhoon, 3 of them @ 3.510Ghz & 1 @ 3.600Ghz. It does seem that 3.240Ghz is where the first stumbling block comes in I have found, but I've been able to come up with a system that works for me to get them up in the 3.5 to 3.6 range. So far it has worked on all 4 PC's.

The first thing I would do if I were you is dump the OCZ Memory & get some Corsair X2PC6400C4 Memory with 4-4-4-12 Timings. OCZ Memory is good Memory but the DQ6 Motherboard doesn't like it for some reason, I had some OCZ Memory in one of the Systems & it wouldn't run right most of the time & I couldn't get it to OverClock as high as the Systems with the Corsair Memory. Once I put some of the same Corsair in that system as the others it went right up to the same speeds as they were.

Also I don't think you have the Cooling to get to 3.5Ghz - 3.6Ghz, I notice your running 60c now at load while only running @ 3.24Ghz...My systems run between 40c-50c under full load as I keep the room their in very cool. Your either going to have to cool the Room more or get better cooling for the CPU & Case or your System won't handle the Heat ... If your running 60c now you probably would be over 70c @ 3.5 - 3.6 GHZ

Now for the System I use - First off you have to Disable a lot of things or the Overclocks won't work...

[ADVANCED BIOS FEATURES]

Limit CPUID Max to 3............................Disabled
No-Execute Memory Protection..............Disabled
CPU Enhanced Halt (C1E).....................Disabled
CPU Thermal Monitor 2C (TM2)..............Disabled
CPU E1ST Function..............................Disabled
Virtualized Technology...........................Disabled
Full Screen LOGO Show........................Disabled
Init Display First....................................PCI

1. You shouldn't just jump up to the speed you want right from the stock 2.40 Ghz, go in steps to try to attain the 3.5 - 3.6 range.

2. You should be able to boot @ 333FSB = 2.980Ghz without any Voltage changes...Re-boot once set to 333Fsb

3. Then from there you should be able to Boot @ 360 = 3.240Ghz without any Voltage changes...Re-boot once set to 360Fsb

4. Then go to 370 FSB = 3.330Ghz, set your System Voltage Control to Manual & your CPU Voltage Control to 1.52500V - Leave the rest of your Voltage settings alone ... Re-boot

5. Then go to 380 FSB = 3.420Ghz & set your DDR2 V Control to +0.025V -- MCH to +0.20 -- FSB OV Control to +0.10 -- CPU Voltage Control to 1.55000V ... Re-boot

6. Then go to 390 FSB = 3.510Ghz & leave your DDR2 V Control @ +0.025V -- MCH to +0.30 -- FSB OV Control to +0.15 -- CPU Voltage Control to 1.57500V ... Re-boot

7. Finally you can try 400 FSB = 3.60Ghz, you may need to go to MCH = 0.+35-+0.40 -- FSB = +0.20 & CPU Voltage = 1.60000V to attain that Ghz, personally with Air Cooling if you can get to 3.420Ghz or 3.510Ghz I would be happy & not bother with 3.600Ghz as most Systems won't take the heat on Air...Good Luck

Well, I finally got my system stable @ 3.40Ghz.
I got a new CPU Fan Cooler; the ThermalTake BIG TYPHOON-V with the variable speed controller & I made some BIOS changes.
My temp readings are now hovering @ around 48C when idle.
When I run 3DMark06 the temp goes up to 57C. This temp reading I get from Intel's Thermal Analysis Tool.

My 3DMARK06 score is 4987 at this speed.

Does this score suck or can this be higher?
December 15, 2006 1:37:38 AM

4987 seems pretty reasonable for a X1900AIW; my 3DMark06 score is about 5700 with my X1900XT, and the XT runs at higher frequencies than the AIW.

As for overclocking, I'm not sure why you need so much voltage for the CPU. My E6400 does 3.4GHz at 1.325V. I do have to knock it up another notch or two to get 3.44GHz, but it's still a far cry from 1.425V.

I, too am having trouble getting higher, but my PSU is an Ultra X-Finity, and I've heard (after I built the system, of course) that they're kind of on the second-from-the-bottom rung. I'll probably replace it with a good PSU soon. Even if it doesn't help me clock higher, it's still a good idea.

Wassup NotAPimecone.
I find that when I run the CPU OverVoltage Control at less than [1.42500V] while running the 3DMark06 the system Reboots. I tested this in small increments. Unless I'm doing something wrong elsewhere... Hmmmm.

Hehe gotta like the Disclaimer.

I did not bother re-reading all but have you tried upping back the multiplier to 9 with the 'new' voltage?

I think that once you pass 400mhz FSB you end up in another strap or at least one with looser timing, I would advice staying around 400.

Now something you might give a shot is skipping altogether the 400-460 FSB range. I don't know if your ram can handle that.

In can you wonder This is where I take my information

I advice you to be careful. You could start by doing some test with memory divider to see just how far your ram will go.
That being said, it's becoming somewhat hardcore, if you don't feel comfortable I advice you to stay with what you have and not to move the voltage any higher.

good luck

What's up labbbby...
I do have it @ 9x. I try things in baby steps. It's painful this way, but safer.
When I get home tonight I'm going to try changing the CPU Clock Ratio multiplier to 7x & a CPU Host Frequency (Mhz) of 486 to see if I can get it to work at a lower voltage. It should yield me a 3.4Ghz result if my math is right. Burn baby burn!!!
My goal is to leave it at a stable setting overclocked fulltime without worrying about electrical path degredation, funny hot electrical circuit smells, etc.

March 9, 2007 1:07:33 AM

umm okay im confused... ive been overclocking for a bit, but here is 1 thing i dont get!!!

SETTING:
ddr2 : +0.300 ((its rated 800 MHZ 5-5-5-12, OCd to 800 MHz 4-4-4-11))
MCH : ( +0.05 ) <<<i was stable without increasing it at all hense i dont get how this should help if it was upd by 0.40 or something like that.

CPU : ( from 1.31250 to 1.36250 )

>>> i was also stable with 1 step less in CPU voltage, the readings from windows is different, im talking about Bios readings...

now as for my multiplier, i lowerd it to 8, from 9
and increased FSB to 400, and put ratio 1:1 scoring a full bandwith, 800 MHz 4-4-4-11 rams, im at 32 to 35 degrees idle, and i was stable for 6 hours under dual primse stress... max temp i reached under full load for 6 hours was 65-66 Degrees... so however.. why would i want to raise MCH, i also read on some websites, that u can increase MCH voltages, without increasing CPU voltages to get stable.. and FSB voltages, isnt increasing this basically useless?? or atleast explain the benefits of each voltage increase..

thank you, and im not that experienced with forms and stuff like dat ><
