P4c800 + 3.4ghz

[regimentaldj]

A quick p4c800 deluxe question...

Just replacing my 2.4 (800fsb)p4 with a 3.4 northwood (800)p4. I have flashed the bios with rev1019 using Afudos 2.26. This processor should therefore be supported.

However it keeps turning itself off after 2-4 mins. I'm using the 2.4 stock cooler on the 3.4cpu but I don't think it is a temp issue cause the motherboard reports cpu temps are satisfactory.
Getting confused and annoyed cause this is delaying my STALKER gaming.

Yeah power settings are all fine.

other specs:
x4 256 ddr400
ati 256 ax800xt
sata 320g HD and IDE 80g HD

A few changes and it took a little longer to turn itself off. I have upped cpu volts to 1.6v and changed Dram idle timer to infinite. And Dram refresh to 7.8usec.

To be fair I have no idea what I'm doing just reading random bits of stuff from old forum posts and giving them a go

edit: those settings made no difference, but had it going for four hours + stressed it ...now back to turning off in first few mins

Think its my PSU guys. Got it in the folks pc running fine on an Abit-AI7. Its a Hyper-X if i recall and should be sufficient Watts for the system, infact the folks pc has a 400W generic psu and its working fine...they might be keeping the CPU!
Thanks for all suggestions btw
