    Okay, here's the link to the page of previous benchmarks for this cpu: http://www.mersenne.org/report_bench...ic_cpu=4377447

    and here's the mprime benchmark output from mine. I'm not sure how to interpret it. Do I compare the "best time for" section to the benchmarks, or the "Timings for " section, looking at 4 cpus running 4 workers?
    And for what's it's worth, under linux, the screen output for normal work for FFT 2M, pass1 256, pass2 8K (all 4 cores the same) was from 31 to 39 ms/iteration.

    Okay, more data. I've downloaded Intel Extreme Tuning Utility, and it shows TurboBoost is disabled. But it's enabled in the bios, and Win7 power setting is on High Performance. So I don't get it. And yes, it is enabled in the bios. Any ideas?

    Another edit: I reset the bios to factory settings, and under Intel XTU, it now shows TurboBoost is enabled. No difference in performance, though. I did the prime95 torture test modes, the highest heat mode got the watts up to 63 and the heat to 159, the highest power consumption mode was 44 watts and 129 F, the same as normal operation.
