My OC, please see.

[TBlaar]

hi to all.

i decided last night, that I want to OC my PC a bit.

The suspect:
Intel P4 640 (3.2GHz, 2MB L2, no virt, 800mhz)
Gigabyte 8I945P-G (1066fsb, ddr2 up to 667)
Corsair Value select DDR2 667, 2 x 512s (5.5.5.15)
Seagate SATA 160GB, WD IDE 40GB
Front and rear 12cm fans.
AOpen 450w PSU

I am still using the stock HSF on my CPU.
Front 12cm fan suck and rear 12cm exhaust.
Win XP Pro SP2 on Sata 1 drive @ 150

Here is a screenshot of PC on idle.

the Gigabyte utility I dont use to overclock, i do all in the BIOS. this utility only shows what everything is set to in the bios.

fan01 is the cpu fan, fan03 is the rear extracting fan
temp03 is the cpu, the others stay at those temp permanently.

when I run 2 primes under stress and superpi at 32M, the cpu temp goes up to around 60C, and the fsb fluctuates a bit. all is stable though.

please comment on where I can improve, where I can cut.
also, would anyone be able to tell me what ratio my fsb:ram is etc.

please comment.

That's not a bad overclock, so far. You might be able to increase vCore a bit, but the extra heat might be too much for stock cooler. Considering that you're using Value Ram, 782MHz is pretty good, but you're likely going to have to change the divider to lower the RAM speed. Right now, you're using a 333MHz(3:5) divider. You should try a 266(3:4) divider, which will have your RAM running at 626MHz (at current 235FSB), and still have more room to go. GL

thanks, will try this. also, my ram timings, according to Speedfan, can run 4.4.4.12 at 266. can I set my timings to this if i clock down to 3:4?

more things, eist, max cpu id 3, etc is all disabled.

and i went past this last night, but not in bios, with utility. max was 3896mhz at 1.42 vcore. then it was freezing. i can prob up the vcore mroe, then it should work. but i do need better cooler...

I would keep the timings where they are, until you find the CPU overclock limit, then once it's stable, work on lowering your timings. I imagine they will run 4-4-4-12 @266, but if they give you troubles, try increasing vDIMM a touch.... .10v-.20v. GL
