Q6600 - Can't get past 3.04GHz

GA-EP35-DS3L
Q6600 w/ Arctic Cooling Freezer 7 Pro
G.Skill 4GB (2x2GB) DDR2 800
Vista Home Premium x64

I've run into a wall with my overclock: I'm stable at 3.04GHz (380 fsb x 8 CPUM), but anything above that and I get a BSOD. I've tried to get higher with different multipliers but it's the same story every time. I've flashed to the latest BIOS, and my current settings are as follows:

-CIA2, C1E, E1ST, Virtualization, No-Execute Memory Protect, and any other speed enhancements have all been disabled.
-1:1 RAM divider with 5-5-5-15 (default) timings.
-DDR2 Voltage: +0.2V
-FSB: +0.1V
-MCH: +0.1V
-CPU Volt: 1.35625V

I'm fine with temperatures, and I'd like to get to 3.4GHz. Any suggestions?

Enable loadline calibration if your board supports it. Also increase vcore further. Intel's "recommended" vcore for Q6600 is up to 1.5v. It's a tough chip, and will tolerate a lot. Keep an eye on temperature, of course.

i think now most thread created about the Q6600 is where the simple Vcore increase doesnt satisfy the speed of the chip.

i think its time to update the stickies on these issues!

wouldnt you say so dagger;)

List your VID, try increasing Vcore.

i bet its 1.315 or even 1.325v!lol

My VID is 1.325. I raised the Vcore to ~1.435 and now I'm running at 3.4. Thanks guys!

I think I could go higher, but I need to know more about temperatures. I know it should stay below 70c, but is that for individual cores or the cpu as a whole?

71C on the cores.

just 71C is fine. but 1 more is really no good.

General safe temp limit is 65C. I don't like going over that, but the Q6600 G0 can handle up to 70C on the highest core temp without any major damage.

what the point of that?saying the limit is 65C but 70C is ok as well.

so whats the limit?LOL

A G0 Q6600 shoud be able to reach 3.0 GHz at stock voltage with a decent HSF. Upper range with an ACF7P shoud be around 3.2 to 3.3 GHz.

My Q6600 has a stock voltage of 1.2625 volts. I can reach 3.6 GHz with a TRUE/S-Flex fan at 1.45 volts drooping to 1.400 volts with a GA-EP35-DS3P. Prime95 loaded core temp is around 65 C.

jssc you will make him jealous or even angry since he got such high VID.lol

The limit is 71C. Once it reaches 71C, the cpu will automatically drop back to 6x, no matter what your bios settings are, to cool off and protect itself.

once i had it at 85C it didnt throttle off. it was a G0 Q6600. so you get my point?

Lol, then there's something wrong. :na:

lol hmm.....i dont know. its not mine!hahahaha

I have had mine running hotter then 71C without it throttling. I think 71C is the Max safe temp to run for more then a few seconds.

If i can remember correctly the Q6600 G0 is supposed to throttle at 85C, not sure if that's TCase or not though.

Well, see here, if you let the cpu get too hot, it will start affecting nearby components, such as the NB. In my case, NB is hot enough as is, idling at 49C. I don't need any more heat from the CPU.

get some fan for your case dude. you dont wanna cook egg in your computer!lol
