Recommended FSB for a daily use?

[Stupido]

Folks,

I have GA-P45-UD3P with Q9650...
I plan to overclock and I'm wondering what should be recommended FSB for daily usage?
I tried some overclocking just to see how it will go, and was able to get windows boot with FSB @ 500 MHz. But the heat sink on the chip set was very hot. Almost burned my finger when touching the heat sink for few seconds...
Thanks for the suggestion.

If you want to play it safe, just see how far you can push it with stock voltage and make sure the temp don't get over 70C (ideally under 60C, but not a must) under load.

How high did you crank up your voltages?

May also want to reseat your boards heatsinks.

use coretemp to monitor your temperatures, and run a torture test using Prime95 to make sure you have a stable system. if you have no voltage increases then IMO you can run you CPU at any clock you want, quite safely.

Actually with CPU at "AUTO" voltages I was able to go above 4GHz @ 1.38V (475x9)... 😀 but when using prime95 (large FFT) the temps quickly rises above 70 deg, so currently I'm not very keen to keep it...
I have IFX-14 but with only 1 fan Scythe Kama PWM 120 mm. I have ordered 3 new Scythe Kaze Maru (140 mm @ 1200rpm) for push-pull setup and I'm hoping to get the temps OK...

Ah, yes, I'm using realTemp & HWMonitor for monitoring temperatures...

#1 killer of hardware= AUTO setting

I left CPU related to auto and played with the MCH voltages:
Core - 1.3V
Termination: 1.35 or so...
PLL: same as termination
rest on auto

😀 yes, but when I start to really overclock, than I'll play more... However, with auto in BIOS, HWMonitor showed 1.38 for VCore and the CPU was already @ 4.2 GHz... So it looked OK to me. Further more I read on some forums that people normally go with 1.4 or 1.42 VCore to get to 4GHz

You may want to set your voltages to their default or minimum values rather than leaving some on Auto. If you can verify it's not over/under volting while set to Auto your OK, but I've always found it easier to set them all so I didn't have to worry.

What's your GTL?

Vtt= 1.35 or so....is fine (lower the better though)
PLL=lowest value usually 1.5v

 

[Stupido]

Oh, PLL indeed could be 1.5V... I don't know them by heart.

I will give you links where people have taken their Vcore up to 1.8v and PLL to 1.9v and left the computer run 24/7 at 100% load with no problems that doesn't mean I ever would.

But how far you push your chip is completely up to you. Good luck.

Thanks
I'm only interested on how much is good enough to reduce FSB bottleneck 😀
