NICE! Although you seem to hit a brick wall around 4ghz getting 3.8 on 1.275 is great.

when you pass 3.8GHz in phenom chips, it becomes voltage hungry. Even more in your case, since it's an unlocked chip.

3.8GHz at 1.275v!?

I'd rather have a CPU run the lesser speed at LOWER THAN STOCK VOLTAGE rather than 4GHz at near the max. O_O That's nuts!

EDIT: You're pulling only 100w with the 3.8GHz overclock. Nuts...

Congrats! You are now just 5 watts away from being able to put that in a 125w MSI!

Wow, that is impressive if it is prime stable. for me to hit 3-core @ 3.8+ it takes 1.5375v... For not until I can get my watercooling efforts back into swing anyways :-p

Lol impressive voltages!

My 1055T needs 1.35V (LLC disabled) to reach full stability at 3.6GHz, so guess how crap my chip is and how golden yours is

Nice OC. However, it's best to backup your OC with some type of stability stress testing screenshot.

I hit 3.7 on 1.408.

The callisto CPU's are all over the place for OCing. Probably the least consisten overclockers in the phenom family.
