Hey guys i apologise for not having the opportunity to search the entire forum before posting this as my pc isnt working atm (just got the new cpu this morning) and im at work so got to be quick.

I'm a noob to overclocking and want to oc my E8400 to a sensible speed.

Is there an easy way to do it or do i have to go through all the guides etc.

Sorry for my ignorance.

Many thanks,

I've read the guide and tbh i cant make head nor tale of it, all i can see is i have to mess around with my ram, thats the bit thats getting me, i know about the vcore and multipliers etc it's just messing with the ram, why can it stay on auto??

Cool will look into doing that tonight once it's up and running, dont suppose you have any working ratios do you? (I know every chip is different but would give me an idea hehe)

I really appreciate your help.

Hey man, thanks i tried doing that but it's overheating on everything lol.

I've put it back to stock and im gonna prime95 it and see what it's doing... @ 9% load it's avging abour 54deg... it's not the case temp cos thats fairly low cold to the touch... im thinking maybe the thermal paste isnt doing its job... what do you guys think?

I didnt get to test it out with any substatial load but i suspect it will still overheat and restart.

What do you think it could be?? All i've done is simply swapped out my old E4300 for my new E8400.

I did a bit of digging and there was a post from last year where a guy was having the same trouble, apparently they dont work well together the nvidia chipset is pants for 45nm chips! This is NOT good lol. This was done last year though so last night i updated my BIOS to 1406 in hope they've fixed something within the last 3 bios releases lol.

yeah my old E4300 or w/e it was (the 2.44ghz one) was perfectly fine. Yeah it's clipped in correctly. I noticed the bios 1403 upped the compatability with the E8 chips so we'll see tonight when i get back. I might just put my Akasa AK-961 fan in if i can be bothered to get some artic silver hehe.

I'll let you know how i get on later.

Forgot to mention it was idling at about 50deg going through to 80deg at which point i stopped the load. It actually reset twice before i changed the bios. the ventilation isnt the best but it's got plenty of fans in the case so it's pretty cool.

just got home, running at 43deg idle, then i ran prime95 and it shot up to 90deg in the space of 1min. At which time i shut down prime95 lol
