SMT Control, Core Performance Boost, C-State Control (various settings), APIC mode,... Basically everything under CPU and Northbridge settings.can you elaborate a bit? which settings?
Problem is: it works on the Rome one. And both designs are too similar for such a difference. So its either some bug or config in Windows or Hardware.Hyperthreading is on (as the number of blue boxes in task manager shows)
Even when you were running 100% on all 24 cores, that was 100% at 3.0GHz. Quite a bit lower than the 3.9 all-core seen by @lihpBut what I find interesting is that if the task is neither single threaded, nor does it uses all cores, it seems the CPU will run below its max clock speed, which surprised me.
So far I only implied but please @ca3y6 could you monitor CPU temperatures under ffmpeg load? And come back an tell us? Maybe a bad contact on the cooler to CPU lid, maybe a setting in BIOS/Windows or you missed some settings when running ffmpeg on the 7443P.... If ffmpeg only uses 12 cores for instance, then the 16-cores 7302P is almost at capacity whereas the 24-cores 7443P has ample leg room,...
Actually you were right. If I set the power plan to High Performance (from the default Balanced), then I get the expected performance profile. Mystery solved! ThanksWindows Power plan, is it at High performance or something like that?
you can boot some Linux live, stress the Cpu and watch for Cpu speed.. - it will prove Windows or Bios..
Just to add what I meant with 3.90+ GHz. Right now doing some tests (not full load but close) and thought to make you a screenshot. Once I make a full load test again I will see if I can hit a screenshot at 4.00 GHz +Shouldn't the 7443p be boosting closer to 4.0GHz, not 3.0GHz?
I'd be interested in seeing what temps are like at full load. I was planning on using a dynatron A26.Just to add what I meant with 3.90+ GHz.

In that league it probably comes down to personal taste. I was actually quite "afraid" of the noise my server will make in my office. I dont hear the server at all - only rarely like every two days I hear the Ultrastar drives working for a brief moment. Thats it. My Workstation is (still for now) louder, while I dont hear anything of the server (besides above mentioned drives).250W TDP on the consumer be quiet! cooler vs 280W on the A26. The A26 is a lot noisier at load though.
