If I can let tb shut down 1 or more cores and get another multiplier's worth of clock out of things (say 4.166 GHz on a two cores or 4.333 on a single core) then I'm very interested!
In Real Temp, right-click the taskbar icon and you will see Turbo Boost Limits... That's the one.
You don't have to shut down cores. I just now finished an OCCT standard 1h run. My bclk = 134MHz. When I ran it with Vcore = Normal + 0.00625v, 1.312v on load, LinX failed.
When I nudged the add voltage to +0.01250v, LinX was stable for 20 reps and a Vcore on load of 1.328v, but I got a BSOD with OCCT/Linpack. The error code was 00...0101, which means not enough Vcore. So I nudged the add voltage to 0.01875v to get a load Vcore of 1.328v to 1.344v. Same BSOD with same error code.
Now, with Vcore set to Normal + 0.2500v, I get 1.344v on load, and OCCT/Linpack ran the whole hour. The interesting thing is that the cpu is reporting lower temps than I got with my i7 860 with lower Vcores. Such is the variance between chips.
To recap: with Normal + volts, Turbo Boost and EIST enabled, bclk=134MHZ, the cpu multiplier runs 9x to 30x, resulting in a cpu speed on load of 4020MHz, or 4.02GHz. You will have to find the +voltage that works on your own 875k.
