8x 7t WU at a time but I appear to have had an error in the formula. Re-testing.

Okay, so HT on and hitting L3 cache as hard as you can.

I am scrapping all my notes and tackling it from the other end. HT still on but only very low counts of 4t WU until I get an idea of what each machine is capable of time-wise

Note to self: WU downloaded on 11-Feb fit this description

Hmmm - I think my 2990wx machines might be throttling back due to heat. What is their max running temperature before that happens please?
