E8400/E8500 overclocking thread!

Max_87 · 3rd May 2008, 08:52 AM

Just got my E8400 yesterday

VID is 0.9250v, this is so far the lowest I've seen myself

Just finished testing 4GHz @ 1.24v

My E6850 can't even do this with over 1.65v

Now testing 4.1GHz @ 1.27v

Hopefully my ram can handle the speed.

Damn!!! I want one!!!

What does it score at super pi 1 meg @ that speed?

Max_87 · 3rd May 2008, 10:09 AM

Not sure, I haven't tested Super PI yet, but I think should be around 11-12 seconds.

1.27v isn't enough, so I bumped the voltage up just a tiny bit. Now testing 4.1GHz @ 1.28v, so far so good

does your mobo have loadline calibration?

On mine, if loadline calibration is disabled, I need 1.275. otherwise 1.25v is enough to hit 4.05.

that's max my system can go

RAM is limiting me

Try getting the latest CPUZ. Should detect the correct voltage...

FAPFAPFAP!!!

Hm... I downloaded the latest version of CPU-Z, it shows slightly lower voltage, around 0.01-0.02v lower.

Priming at 4.2GHz @ 1.32v at the moment

FAPFAPFAP!

I don't think so. I did what Chai said, the latest version of CPU-Z is giving me ~1.23v at 4GHz while the older version shows 1.24v.

Seems like my ram is doing fine at 467MHz.

I got mine to 4.0 GHz at @ 1.35 V, but I can't find the screenies I took back then. Right now, I'm at 3.6 GHz no voltage increase.

Max_87 · 3rd May 2008, 04:46 PM

Seems like the previous 4.1GHz @ 1.27v test is limited by my NB/RAM, I couldn't get it to prime stable even at 1.29v, but now my E8400 doing fine at 4.2GHz with 1.32v. I had bumped my MCH and RAM voltage up a notch when I started testing 4.2GHz.
