I'll edit, it just to start the topic

Here's my "junk"

Q6600 g0 VID: 1.3 with a OCZ Vanquisher @ 3.3ghz
P5K deluxe with lastest bios 0812
4x1gig ram OCZ Reaper HPC 8500 @ 1.1ghz (5-5-5-18 2T)
EN8800gt (asus) -> cant be OCed... always get artefact if i push her.
2x HD (not in raid)
Dvd burner IDE
All in a small pretty black Asus case

At this moment im sitting at 3.3ghz (366x9)
The lowest voltage i was able to get stable is
1.376v -> idle
1.368v -> full charge

Prime95 stable for 24hours with ATI stress test (was looking for the highest temp this small case could handle)

So here's my goal... OC at 3.6 with my temps lower than 71c-72c and a vcore lower than 1.5, and maybe play with my ram latence and speed.

-> going in the bios

Thanks a lot for your help :)

Bios:

Cpu Ratio -> Auto
PSB Strap to North Bridge -> auto
FSB Frequency -> 366
PCIE Frequency -> auto
DRAM Frequency -> 1221
DRAM Command -> auto
DRAM Timming -> auto (for now)
DRAM Static read control -> auto
Transaction booster -> auto
Cpu Voltage -> 1.400
CPU PLL Voltage - > auto
FSB Termination -> auto
Load-line calibration -> auto
CPU spread spectrum -> disable
PCIE spread spectrum -> disable


In the CPU section i disable everything except ratio to auto

Try 1.45V and above (BIOS) for Vcore.
You could raise the FSB and (G)MCH/Northbridge voltage a notch for 400MHz FSB but you might not need to.
I tested at 6x400MHz to make sure it was stable at 400MHz FSB before raising the multiplier.

EDIT : Set the memory to 1:1, 3:4, 5:6 or unlinked 1066MHz. If you overclock it with your FSB it might become unstable. It also makes it harder to pin down the culprit of the instability.

What PSU are you using?

My Q6600 experience in a quest for 3.6GHz (9x400MHz).
The base details:
My Q6600's VID is also 1.3V.
I need 1.22500V for 3.0GHz (9x333MHz, 24h Prime95 stable) .
I need 1.29750V for 3.3GHz (9x367MHz).
I tried upto 1.4V for 3.6GHz (9x400MHz, boots into XP, I can do most daily tasks but it crashes Prime95 in a matter of seconds).

Im using an OCZ GameXStream 600w

Thats exactly my problem... i can boot at 9x400 but prime95 crash...

I also wanna keep a low temps (i know my fan suck but)

For 3.6 you'll need 1.45 After VDrop and droop. In other words, Loaded! (Loaded is while running prime 95 small ffts or similar progies.

VID = your default factory starting voltage!

Try FSB 400, PCIe 100, Dram frequency to 1:1 sync mode, Static read disabled, disable transaction booster for now, CPU voltage to 1.5000, Load line calibration enabled!

Good luck!

tried... i also push the vcore to 1.525... no success... look like theres something im doing wrong... i can boot to windows but after 3-5 sec of prime 95... restart...

Is there another option in my bios i should turn off?

Thanks a lot :)
