To all Phenom users with x64bit OSes

[Lightman]

I was running 2511MHz on my old 9500 for almost 2 weeks. It was semi stable, but I had one or two blue-screens (famous interrupt error) during a day. I could run 3DMark06 test, but not full suit. Crysis was most affected by instability. Cinebench x64 or LW9 no problems, even AOD stability test was passing 8h stress!
I've even did couple of test @2.6GHz under x64 but only with 2 or 3 cores at these clocks and 1 or 2 below 2.4GHz.

There is one thing I haven't tested. How increasing CPU NB vcore affect stability. My board doesn't have an option to adjust it.

With regards to ES samples I think they are using different manufacturing parameters to make them clock faster. In other worlds if you will measure power consumption of AMD Phenom ES and retail Phenom at the same clocks I'm sure ES will use significantly more power. I saw this behavior in one or two reviews. I suppose AMD decided to pursuit performance per watt as a logical thing to do now till buggy rev. B2 will be replaced by B3 or even 45nm successor.
Because ES samples are built using faster switching transistors (more gate leakage) they can clock a bit higher in x64 as well. If thats the case then we are dealing with slow path that needs to be addressed by new revision. What is strange is why clocks are not scaling at all with voltage increase and even seems to be scaling a bit with voltage decrease? Hot spot? Anyone with chilled water or sub-zero cooling to investigate that?

@Justapost I'm glad as well. This is another I bought, my previous one is still at Scan RMA.
