Iâ€™m just building a system with a similar combo of CPU/Mobo and that sounds a decent saving. What application did you use to load the CPU when measuring power consumption?
I usually use Orthos but when I initially ran it only the first 2 cores in Task Manager were loaded and Iâ€™m not clear which are the real cores and which the SMT cores. Would someone please confirm that for me?
Iâ€™ll try running two copies of Orthos and play around with the affinity and see how that affects power consumption and temps.
I use CPU Burn-in. Not sure how it measures up for maximum load. But I found it a couple years back and have continued to use it. To get to a full 100% CPU load, I ran 4 instances of it.
I don't know a lot about HT but I'm pretty sure you don't have real and "fake" cores. Each real core acts as two cores. I would expect that if you're using 2 cores, it probably balances it so that you're using one from each physical core. Then if something starts using the 3rd and 4th core, it might just slow down the other cores since it than has to share physical cores.
For instance, if I run 4x CPU burn-in and then try to run FurMark, FurMark moves very slow since it does need some CPU power. But if I just drop down to 3x CPU burn-in, then FurMark runs just fine even though it's sharing that 4th core with one of the CPU burn-in instances.
