Be a bit more helpful than that.

Full system specs.

Does it boot at stock speeds?

Is it an E0 or C0? I have a C0 that does 4GHz with a bit of extra voltage and i think most E0s will do 4.5. Check your ram is not being oced by lowering its multiplier, what motherboard are you using?

Yeah its fine, but as soon as you change anything else it doesnt do anything

E8400 stock at 31c ( C0 )
P5N-E-SLI
2 GIG DDR2 PC6400 ( Standard timings )
450 VX CORSAIR
8800 GTX

Have you tried running orthos or intel burn test at stock? Might be a bad cpu, if it is stable at stock try setting the clock up by 1MHz, although you should be able to go straight to 3.6GHz with ease.

I'm running an [email protected] on the same board,what bios version you using?

Walkerie · 27 Jun 2009 at 00:14

I just tested it took 49.6 seconds speed 12.1776 gflops? 3.85410e-002 whatever that is i did it on 1gig ram.

0901? 02/01/2008 apparently.

That's very odd. I'm running the same board but different chip; it should let you muck around with the BIOS. Maybe update the BIOS to the latest version. I'm on 1001, but I think there have been subsequent releases

Update now, can overclock it using AI tool but it hangs and sometimes doesnt post. =[

Im using bios version 0803 on mine, maybe update yours to a newer version and see if that sorts it?

Also have you messed with any voltages?

Walkerie · 27 Jun 2009 at 09:41

Its the latest bios now, i havent changed the voltages because tomshardware guide says dont need changing until beyond 3.6

funkeh · 27 Jun 2009 at 21:59

Tried taking out a stick of ram to see if that makes a difference?

Hey all quick update, restarted pc a few times tweaked some settings and now have been ( and all day ) been running at 31c no load, and 48 peak ( but the peak is only measure on the cores so the cpu is a little less )
