Mac Pro 2.80Ghz (2010): what's your max Turbo Boost freq. ?

[dp84]

I noted that my 2.80Ghz (under Windows 7 64bit) gets "only" 2.92Ghz in Turbo Mode instead of what should be (3.06Ghz, in agree with apple site and intel specs).

I know that the Turbo feature is influenced by the CPU temperature, but mine are really good.

Any other experience? What's your max turbo frequency?

What have you tried to max out one core?

SuperPI 1.5MOD.
CPU Affinity set only to "CORE 0"

Turbo boost is a con, you never, ever get one core loaded and the others 'offine' to get the turbo boost to 3.06Ghz for your 2.8ghz Xeon.

My 2.66 only goes to 2.8 and I only ever got it to go to 2.93 was to disable all but the 1st core in Windows 7 using the bootconfig .

The upside is that your 2.8 will always be at 2.93ghz with all 4 cores loaded.

Personally I think turbo-boost is a waste of time.

before the mac pro I had a custom PC with a core i5 750 (2.66GHz with Max Turbo Freq. at 3.20Ghz).

in the same conditions as I tested the mac pro, the i5 750 gets up to 3.22Ghz, as expected.

anyway turbo is not a waste of time, but it does not change my life, it was just curiosity
