Volts Question: E8400 to 4GHz. - Page 4

post #31 of 41
Thread Starter 
1.56v! Holy crap man... lol hope you have a second cpu handy.

I quit my E8400. I just can't get stable after 3.3 and it won't post after 3.4. I have no idea what I'm doing wrong, I've tried countless things but I just have nothing else I can do.

Ive really never overclock in small incruments but, there are risks envoled when i broke a P5N SLI board.
post #33 of 41
yer 1.5v i dunno i overclocked a E6600 to 3.5ghz at 1.5v was fine
post #34 of 41
1.3625v IIRC

The difference between say 3.7Ghz and 4Ghz is minimal unless your benchmarking


Edit: Benfica - 1.5v is the max limit for a 65nm chip

This is 45nm

Unfortunatly people are not respecting 45nm's voltage limits often and running a voltage that will risk their CPU randomly dying or degrading

But you will!

Max Voltage without degradation is 1.36!!!

REDUCE VCORE NOW !!!!

i got a big performance boost when i bought a new motherboard

how long you think it will last at 1.5volts ive been running this for 2-3 months now no problems?

hardware monitor is just that. there won't be any settings to change voltage there. you have to go to advanced settings

I see that on your sig rig, you reduced your Vcore and your clocks .
Not enough man...
Please, dont fry that lovely CPU...

Overclocking takes time and a lot of trial and error. A lot of people make the mistake of volting the hell out of their CPU and don't put enough time into tweaking all applicable settings before adding VCORE.

I usually start at default MHz, find out the absolute lowest settings that I can run stable, then start working up from there. In my case, at default speed, I can run ORTHOS for hours with VCORE, Northbridge, Southbridge, etc at the lowest settings available in BIOS. I raise my FSB a few MHz at time and run ORTHOS. When I hit instability I bump up the other settings one at a time til I get it stable again, then I start to move FSB up again.

At default 3 GHz speed - 1.056v:
