... the multipliers averaged around 38-39x after that (i.e. 3.8-3.9 GHz clock).

Apparently it matters a lot just which algorithm I'm using at the time, as well as how many workers are sharing 16 threads, how much RAM is available, etc. With Prime95 running P-1 jobs the multiplier goes up to a steady 40x in the first stage and 41x in the second. I tried running something called ThrottleStop which allows a little tweaking (but not resetting PL1) and that squeezed out a bit more -- occasional bursts up to 45-46.5x, with TPD going over 100W at times and temps as high as 92C. I think when the new cooler comes in I'll be able to get most of what I want just by removing more heat. If not, I'll have to learn how to modify the EFI and/or BIOS -- it's not clear what the distinction is on this newer machine.
