Thank you for the warm welcome, Gents!
Lorec ... I am a core whore
I'll blow a bunch $$ when the 4950X hits with 32 cores and 64 threads.
Took me a *lot* of iterations before the 3950X settled down. I am on ASRock X470 Taichi and finally got AGESA 1004B in February. The temps were blowing up (over 75c) and so I had to reduce effort to 100% cores and 50% cycles to get it down in the 60s. Now with 1004, my motherboard got ECO mode, and I am back to 100/100 with temps 50-60. Gut level reaction is that I am probably getting 80% of the results with about half the wattage. But I am willing to be educated if there is a better way.
This is on a Corsair H100 AIO. I was considering a switch to a 280mm AIO or experimenting with Noctua air cooler, until I hit on the ECO.
