First try at overclocking = fail

Ok, so I just got done trying to OC my Q6600 on my P5Q-PRO.

Here are my settings on the advanced tab:

AI Overclock Tuner - Manual
CPU Ratio: 7
FSB Freq: 400
PCIE Freq: 100
FSB Strap to NB: Auto
DRAM Freq: DDR2801
DRAM Timing: Manual (4-4-4-12)
...............................
CPU Voltage: 1.28
CPU PLL Voltage: 1.60
FSB Termination Voltage: Auto
DRAM Voltage: 2.0
NB Voltage: 1.38
SB Voltage: Auto
PCIE SATA Voltage: Auto
.................
Load Line Calibration: Disabled
CPU Spread Spectrum: Auto
PCIE Spread Spectrum: Auto




Does that all look ok? Something must be wrong, becasue when I started Prime95 it instantatly crashed
 
Try upping the cpu voltage a bit. What kind of ram do you have, exactly?
 
definitely just take your time, watch your temps and voltage...OCing takes time and patience....sooo many variables to consider
 
Go slow, raising the FSB until it fails.
When it does, up the voltage a bit and see how far it will go. repeat.

Alternatively choose the max voltage you want to use and raise the clock speed until it fails.
Be sure to have already found the max speed of your memory and motherboard so you know what is limiting you.
 
That OC should be a piece of piss with any decent 800mhz RAM.

Try your RAM at 5-5-5-15 tho if it's not 4-4-4-12 by SPD.

The majority of failed OC's on decent 775 set ups come down to RAM.

Everything you've done looks very modest and safe so although i would raise the CPU to above 1.3 volts.

If RAM @ 5-5-5-15 fails then i would go so far as to say that something is wrong. "Your milage may vary" when it comes to OCing is of course true but a Q6600 on a P5Q @ 2.8 ghz is nothing!

RAM baby, loosen that shit up.

BTW - what RAM have you got!?
 
thanks for all the info guys!

The RAM is OCZ Platinum Rev.2

I upped the VCORE to 1.32, and it ran for 11 hours 0 errors :) Max temp according to Real temps was 57C, does it ead 5C low though? HWmonitor said the max was 62C, which is odd. I'm gonna up to 3.2Ghz and see how it goes, but I'll loosen the timings so that it eliminates a possible bottleneck.
 
well, it wouldn't post at 3.2, so instead of messing with the settings a ton, I upped the vcore to 1.4 and I'm doing 8x375.... we'll see how hot it gets
 
You had best read up on overclocking the 45nM chips with high voltages of you wish to exceed ~1.36V.
I'm taking my "own" risk running 1.4V.
 
UPDATE

I got it up to 8x400 stable for 6 hours on Prime. Temps maxed at 61C.

I tried 3.4 and 3.6, but it wouldn't even boot into windows, even with a 1.45 Vcore :( might have to play with it some this winter.

As of now I'm leaving it at 7x400 with a 1.30 Vcore for the time being (maxes at like 50C), then maybe this winter I'll bump it to 3.2 for daily.
 
Here's a question:

Everything's running great. I want to enable speedstepping so that the computer can clock down and save power. I'm running at 7x400 though, would it even be possible considering it isn't starting at a 9x multi? Also, which option enables it on the P5Q pro, I don't see it in bios.
 
Well there should be a setting in your Bios. I would think that the CPU would drop to maybe 6. I don't know what it will drop since your only at a 7 multi. Wouldn't hurt to try it. As long as your IDLE temps are low I wouldn't worry about it unless you don't like the power draw of it. Good Luck
 
Why not just run at 9x311? Your putting more strain on the NB, mosfets and chokes than is needed to achieve 2.8. ... 400 FSB is not some "magical" number for the Q6600, even with DDR2-800. If anyone here can show me a "SIGNIFICANT" noticable difference in running 1:1 as opposed to with a divider I'd like to see it. Set the memory divider to 2.5 which will run the mem at 777. You won't see a difference between 777 and 800 either. You could also try a higher divider to slightly overclock the memory. Also, by raising the multiplier and lowering the FSB you'll get a significantly larger stepdown with speedstep enabled. 2.8GHz to 1.86Ghz instead of 2.8Ghz to 2.4Ghz. There should be a setting in the BIOS for EIST and C1E. That's to enable speedstep.

BTW, what's the VID on that Q6600? 1.3v to achieve 2.8Ghz seems a little high to me, considering I've been able to achieve 3.0Ghz at VID voltage on 3 different Q6600's. Unless you got a 1.325v VID chip. Also, what cooler are you using?

Click to expand...

I'm using a S1283.

What are your other voltages set at? Mine is set at 1.30 Vcore, but within cpu-z it shows up at 1.24ish, which I've heard is the true vcore.

How doI check my VID?
 
Programs like CoreTemp and Everest will show the VID of the CPU.

As for my other voltages the only one I raised was my NB voltage by .1v.
