Help with OC'ing a P42.0A

[Schnieds]

Hey,

I just got the following setup and haven't had the best of luck OC'ing.

P4 2.0A O/C'ed to 2.2A
110 FSB / 110 Memory (1:1 ratio)
1.525 Volts CPU
ThermalTake Heatsink/FAN
Soyo Dragon Lite P4S 645D (SIS 645)
Crucial PC2100 CL 2.5 DDR 2x256
VisionTek Geforce 3 Ti200

The system won't boot at FSB 113, and at 111 & 112 I get file corruption and data errors booting Windows XP. At 110 I can boot WinXP and run stable as a rock all day long. My temps are in the low 40s while idle and near 45-47 C while under load.

At this point I am thinking that my memory is holding back my overclocking abilties. Does anyone know if upgrading to a 512 stick of Corsair DDR333 would possible yeild a higher FSB? Also, can anyone make any recommendations that I might try to get my current setup higher? (i.e. ratio, voltage, anything else)

Thanks!

Bump - cause I need help getting past 110FSB!!!

I have not tried to OC a 2.0A, but you may have a little room to up the fsb. The 2.0A has a X20 multiplier which normally is not best for overclocking.

If your chip is really good, you might be able to get up to 133fsb. You will most likely need to set the vcore close to 1.70v, to get there.

It would be very unlikely that at those low fsb settings that it is your memory holding you back.

set your fsb to 100 and your mem ratio to 3:4 and test if its your memory.

Thanks for the suggestions. I will test when I get home tonight!

I really really really hope it's a memory limitation and not a CPU...

It looks like you just need to bump up the voltage, but watch your temps, they're getting up there.
