Very nice.

Could probably reach 4ghz and still be completely stable.

I now managed to overclock to 4GHz with the new bios A10!!!

Memory Multiplyer: x8 (for 1333 RAM)

BLK: 200

Vcore: +60mV

Memory: 1.60v

IOH: 1.20

Spread SPectrume: ON or OFF works fine

Turbo: OFF

The RAM goes all the way up to 1600MHz but the system remains stable

Well done Alienware!!! The new bios is fantastic

I'd be very wary about what you call "stable". Did you run prime95 for 12-24 hours? I'll try those settings and report back tomorrow. Thanks for the heads up.

I did run Prime95 on all cores for about 2hrs only, also played games all the afternoon yesterday without a single problem.

So far, I can really confirm that the A10 bios is a major improvement.

I tried the settings and they don't work for me. Computer crashes the second I load p95. Oh well back to 3.6.

EDIT: They do work for 3.8ghz. Not sure how stable it is because p95 has only been running for a very short period of time. At least my computer didn't show off immediately, so that is a good sign.

Have you tried raising the qpi/uncore? Supposedly that's fairly important to improve stability.

Try:  Vcore: +80mV, should help you go through Prime 95 for a couple of hours.

I am now running @ 4.1GHz (205) but I am pretty sure it will not be as stable as 4GHz.

Haven't tried that yet but will give it go and try to go pass 4Ghz.

I just don't think my machine has any interest in breaking that 4ghz barrier :) I'm just gonna call it quits at 3.8, run some tests and make sure everything is dandy. Thanks for the informative post and maybe this can help some people like me who's computer doesn't like to cooperate with them!

I got my i-975 to 4.8ghz. But ran pretty warm.
