Windows 2.3.3 not using all cores in test

My server has 2, 10 core E7-4870 procs, using HT that shows me 40 cores in Windows Task Manager. When I run the test (either 32bit or 64bit), it only ever utilizes 32 of the 40 cores shown, and the results are terrible.

    Thanks, Phillip.

    After examining the log files it looks like the processor group code is working, but there's a simple bug that's limiting Geekbench to 8 processors per group on your system. I've uploaded a new build that fixes this bug; could you download it and let me know how it works?

    Thanks,
    John

    Sucess! John, thanks for your diligence in getting this resolved. Both GUI and CLI use 40 cores/80 threads (not as high of score as I was hoping, but i'll keep running tests) - http://browser.primatelabs.com/geekbench2/903766

    John, looks like this issue is back in v2.4.2. Running the 64bit test in the GUI only uses 32/40 threads, running the 64bit test from CMD line uses all 40 threads.

    The memory also shows incorrect speed: "-1 Mhz"
