Overclock Double Check

[sinabey]

Hello,

I recently bought a gigabyte p43-es3g mainboard and intel core 2 quad q9400 processor and have been trying overclocking. Needless to say, it's my first time. (I actually built my computer from scratch for the first time as well but it's been working )

The system seems to be stable so far and I would really appreciate if someone can go through my quicknotes and tell me whether or not I have missed some very insignificant but deadly detail, which will eventually cause my computer to die out within the next 48 hours .


FSB: 400 Mhz
Multiplier: 8x (system running at 3.2GHz)
FSB : DRAM 1:1 (rams are ddr2 800mhz)

VID seems to be going in between 1.1V and 1.2875V (on auto)

I'm using OCZ Gladiator Max as the cpu cooler. Idle temperature is usually around 42C (38C before OC) and the highest temperature i've seen so far is 72C (monitoring with CoreTemp), which appeared during Intel Burn Test with stress level at High. If the results mean anything:

Time (s) Speed (GFlops) Result
94.086 9.5007 3.068952e-002
55.342 16.1520 3.068952e-002
52.937 16.8859 3.068952e-002
46.094 19.3926 3.068952e-002
30.569 29.2414 3.068952e-00

Seems alright, 72c with IBT is really good. I've no experience with a Q9400 though...

Yes I thought so . If noone sees anything dubious i'll be increasing the FSB a little more. Thanks

Try with prime95. Temps will be lower and more accurate because nothing can really stress your cpu as intel burn test does.

I tried that as well, 0 errors 0 warnings. by the way I manually set PCI speed to 100mhz, which seemed to be a sound action.

VID is fixed. That is the voltage that the CPU programs the motherboard power regulator to deliver.

Just below the memory settings is one for something like CPU Vcore. Take it off AUTO and set it initially to the fixed VID value. When you increase the FSB, you will come to a point where the system is no longer stable. Increase the vcore. Check for stability and CPU temperatures.

Keep working the FSB and voltage values upward. Intel's recommended maximum is 1.3625 volts. Stay under that keep and your load temps under 70 C and you will be safe.

I also recommend that you go into the PC Health tab in the BIOS and set your temperature warning to 70 C.
