Think I must be missing something here as I'm stuck at 2.8Mhz :o

Went straight from 2.4 to 2.8 by upping fsb to 312 on stock volts of 1.225. 2x1gb Geil 6400 ULL at 2.1v, dram speed - default (ddr2-936) reading 5-5-5-15 in cpuz.

Other settings in bios Abit ip35 pro:

cpu vtt - 1.20v
mch - 1.25
dram timings - auto

Tried upping vcore but wont even post at 323fsb, just hangs on the 1st post screen.

Any help apprieciated.
 
Cheers mate, will give it a go.

Seems to have done the trick. Whats considered safe temp's ? I've only got a freezer 7 pro, plus my case cooling is pretty poor so things could get a bit toasty.

Its up to you what is considered safe, most say 70C a top limit, that's under full load using prime small FFT. what your temps looking like at the moment. you will probably need a Vcore boost to go higher.

take a look at the Intel quadcore database for some ideas.

im doing 3GHz with 1.272Vcore according to CPUZ 1.3Vcore in BIOS
that was just by upping the FSB temps are 51,52,46,46. you will see that there is a big diff between temps, this is because the IHS inst flat.

EDIT, as for what I think is safe I'm going to go on till I get 60 under full load. but i'm using low end water so some people will get better results off there air cooling than me. note i am planing an upgrade in a few months

I'm at 3.2GHz on 1.225v in bios, showing 1.20v in cpuz. Temps at idle are 43,40,42,40. How long should prime95 be run for ?

Thanks to everyone for the help so far :)
 
Looks like I'll be sticking with 3GHz until I get a new case and HSF. But many thanks for all the replys guys :D
