Clocking and tweaking P4 Prescott

[brightside_]

Rightio, one of my friends has the followign setup, included is a current CPU-Z dump if it helps.

Intel Pentium 540 3.2Ghz Prescott LGA775 currently @ 3.257GHz (bit random I know)

1.32v

Mult - x16
FSB - 203.14
Bus Speed 814

CPUZ Dump

MSI MS-6728

2x1gb Geil Value
2,3,2,6 (by CPU-Z)
RAM currently on a 5:4 divider running at 162.2 MHz

This started out at trying to tweak the timings on his RAM, as he has the same as me, and mine will run at 2.5-3-3-6 with a slight overclock on them.

When he tightend the timings, the motherboard compensated, i think, by dropping the divider to DDR333 (think thats what 5:4 is)

Now I wondered what the options are with this motherboard, is anyone knows, and what options are available with Intel overclocking so I can help my mate out? Should he try and set the timings back to default?

thanks for any help

I used to have one of those and it's a very good board for overclocking.

You need to turn off all the automatic crap though. Leave the divider on and just ease up the FSB.

For best results with that board I would recommend PC4000 RAM or better as the divider options are not all that useful.

I honestly don't see any point in tightening the memory timings. Intel chips are significantly less sensitive to this than AMD.

Good results are possible though;

You might also want to check the steppings on your P4 as the faster (more expensive) chips generally clock up worse than the cheaper ones. E0 is good news, anything else is a bit pot-luck.

as I don't have access to the mobo itself, he asks how do you turn off all the automatic rubbish?
