im on my freinds computer

heres the specs:

p4 530j 3.0ghz
i945g-m7 biostar mobo
1gb of ddr2 400
oversized intel heatsink/fan
200gig hd
5fans
6600 turboforce

heres the deal:

it wont go over 3.6 ive tried many times, changing the voltages, just about every thing you can think of many different settings and when we try to push it, it just stays at the biostar screen on bootup. When his cpu is oc'd at 3.6 its at 34 celsius under load, and like 29celsius idle and ive got the mobo protectors on so if it gets past 65celsius(wich i dont think will happen) it will shut down. Can anybody tell me how to go past 3.6 and why its staying at that screen? very much appreciated thank you!!

nobody on this question??

ram timings/dividers....? sounds like the ram cant handle it...

TRy running a memory divider If that does not work. It may just be his limit. Did you say if it was S478 or lga775? S478 has voltage droop issues which limit overclocking 3.65 is about where you would start running into these issues. Then you would need to do some voltage mods to your motherboard.

its lga 775

do ALL s478's have the voltage problem...? i have looked for volt mods for my board and cant find any... so can i solve this voltage drop problem by just cranking the vcore up really high?

I dont think so. www.Malvescorner.net used to have a few for the IS7 but i think it was for ram voltage only. Upping the voltage will cause it to fluctuate alot from up to .1 volt which is not acceptable. You can usually help it a little bit by placing BGA ramsinks on the PWM area. The MOSFETS get REALLY hot on the board and they are what regulate the voltage. ALSO you may be able to double up the chokes and capacitors. Cant find the links. But the chokes are the little things with the copper wires running around them. And the capacitors are the battery looking things. If you can find some alluminum caps to replace the ones on your board it could help also. I will keep looking for the site where i saw it. PM lando95 he might have it saved somewhere
