My Q6600 G0 dont wanna oc

[Mech0z]

I really don't get it, I can not even get a stable 3000mhz oc. (was hoping to get 3.2-3.3 with this rig)

My setup is:
Q6600 G0
Abit IP35 Pro
Scythe Infinity
2x2gb Kingston pc2-800
8800gts 512
Antec P182 All fans at low speed
Corsair 620w

Just now I tried 3gz @ 9 multiplier. at 61 degress at hottest core the computer froze.

Also tried 3gz with a 8 multiplier, but then the computer would not even post. (tried 1.35 and 1.4 vcore)

Any idears?

Load temps and other at 2.7gz stock vcore 9multiplier Picture EDIT: this also froze just moments after I posted the screenshot

 

[Cattlegod]

try running without cpuz. i had the same issue and i was like WTF. CPU z was actually locking my computer, even at stock settings. ever since I got rid of CPUz, it has been fine. Otherwise, you could just have an under performer for a cpu.

edit, for reference:

x3220 G0
Abit IP35 Pro
2x2gb gskill 6400
8800 gt

and vista 64.

 

[Mech0z]

So you think just by not running CPUZ, could make my computer run 3gz no problem?

What are your memory settings?

Several recent threads on this forum indicate people leaving their DDR2-800 set to "default-native-800Mhz" or over-clocking to push the memory beyond its spec.

Find out what the DDR2-800 latency-setting defaults are for the memory, select those in BIOS, unlink memory and FSB speeds (not familiar with your chipset, though), and initially select FSB 1,066 and DDR 533.

You can over-clock at a 1:1 ratio -- for instance, to 1,334 and 667 -- by manually setting to those numbers. You may have to bump up your VCORE to something around 1.32V. If it still fails, take the Memory voltage off its Auto setting and try something initially like 2.0V if maximum recommended VDIMM is 2.2V.

You should also be able to OC to a 5:6 or 7:8 ratio. [ . . . . among other viable ratios.]

For instance, FSB = 1334 and DDR = 800 (stock latency settings.) Make sure latency timings are the default for 800 Mhz in the memory's SPD. I think 7:8 would be 1,400 FSB and 800 DDR.

I'm not sure if the CPU_Z software creates this problem. I never ran into it. Perhaps the best thing to do is set everything back to "auto/default" settings, and see if CPU_Z will run then.

perhaps this may be useful. Check your PWM temps when the board is running via the uGuru utility. If the temps jump way way up when the CPU is at load then you can try this.

It's a mod for the heatsinks on the board to make more solid contact with the mobo. It helps alot, I haven't done it myself but I do not have a quad which seems to affect the pwm temps a whole lot more.

HyperX - 2x1024 MB DDR2, PC6400 DDR2-800, CAS 4-4-4-12 - KHX6400D2LLK2/2G

This is my ram. But if I try to use those 4-4-4-12 my computer wont post. (This was with standard volt at ram and can see they require 2V at this setting)

And I havent tried other than that to change my memory settings.

So should I try to do 8 multiplier, 400fsb and 1:1 memory?

yeah 400Mhz FSb and 1:1 would be ideal.

 

[Mech0z]

Just booted to windows with 9x333 1.32vcore, 1:1.2 memory. 4-4-4-12 @ 2V.

 

[BonzaiDuck]

You can drop the multiplier, but I would try to over-clock it at multiplier 9 first.

If the modules are rated as DDR2-800, you should be able to run them as DDR2-667 and get a 3.0 GHz stable over-clock.

I can't tell you about the Kingstons, and I find the revelation that they won't run at their SPD defaults @ 800 Mhz and "Auto" voltage a vestigial symptom more common with the older DDR technology, when memory makers would release DDR-500 modules and they wouldn't quite run at that speed. If yours run at the looser settings provided by the manufacturer, or you have to twist up your VDIMM a tad within 2.2V limit, that's also possible.

You may be able to drop the multiplier to 8 and get to 400 Mhz in a 1:1 setting. If you can't do that, you're more likely to get there with multiplier 7.

But first important to see how far you can go with multiplier 9.

Is your memory set at 1T or 2T. I couldn't overclock anything until I set it to 2T.

I have Crucial Ballistix DDR2-800 @ 4-4-4-12 2T, and have my Q6600 at 3.2 GHz (400x8) with no problems (Abit IP35 Pro MB)

What cooler do you use?

CPUZ reports 2T btw.

I'm watercooling using a Danger Den setup. I'm at 48C max with 4 instances of SP2004 running. I want to push it further (9x400) , but my Vcore is already at 1.38V.

Here's a pic... Still testing it out, just bought the pieces a couple of days ago.

[Mech0z]

Well that don't promise much for my air cooling

 

[Mech0z]

Have it at 8x400 @ 1.4vcore but that gives me blue screen before windows is finished booting.

Going to see how much I can push it up with 9 multi. Is it very bad speedwise to go below 800 at my ram? Because the lowest I can do is 1:1 and then it jumps to 1:1.2 and I have no idear how high I can push the ram with these timings.

With 9x370=3330mhz @ 1.35Vcore I got into windows and had 4 x prime95 running for a minut or 2 before a bsod appeared. Is this an indication of lack of power? (more vcore?)

 

[SRoode]

The BSOD is usually indicative of a memory problem. CPU problems usually reboot before windows.

Try the same settings with memory voltage at 2.1V.

Also, relax your memory timings for now to 5-5-5-18 2T. (That gets the memory out of the equation).

 

[Mech0z]

Okay, but with 1.38Vcore I have ran 4 tests now in Prime95 without crash. So it seems the Vcore was the problem. This is however with 1:1 memory I think so the memory is only running 740.

This seems very stable, no BSODs yet.

An easy way to partition whether you are having "FSB related" issues running at 400MHz (or other) versus CPU stability issues at when the system is clocked up with high FSB is to set your CPU multiplier really low - as in 6x or 7x.

This way you know in all likelihood your CPU is stable (6X multi on 400MHz FSB is stock 2.4GHz for a Q6600).

So if you can pass small FFT's (or better yet for FSB stability is to do Blend and/or large FFT) when running stock GHz on a 400MHz bus then you can start to rule out memory and NB voltage/temp issues as suspects for why you can run 8x400 or 9x400 stable.

I found for example on one of my DS3L's that no matter what I set the FSB voltage or NB voltage to run at the board simply won't clock a 400MHz FSB stable with my quad-core. It will do 367MHz though.

 

[GuitarDaddy]

Whats the vdroop like on your board? Is the 1.38 what you set in bios? what does cpu-z show under full load?

 

[nyker96]

I have noticed my ip35-e has huge vdroop issue, 1.345 becomes 1.288 or so. maybe you need more volts on the chip.

 

[Mech0z]

Seems rock stable with
370x9 2.38Vcore, 4-4-4-12 2V ddr2-740 1:1 divider

Havent stresstested it but I did run a 3Dmark06 after I buffed my memory so I ran
375x9 2.38Vcore 4-4-4-12 2.3V ddr2-900 1:1.2 divider

Vcore was from 1.33-1.35 in CPUZ while doing a Super PI with 1.38 set in bios.
Did that in 15sec btw. no idear if thats good.

Isn't that vcore pretty high for a Q6600 tho? Thought intel recommended nothing above 1.5v? I just started a thread because I'm having a rough time OC'ing my Q6600 G0 as well. Your RAM seems to be of higher quality than mine tho.

DS3L is like that too...pretty sizable Vdroop.
