Hi Nenon,
I imagine that might be an especially welcome option if you're running Linux with the performance power governor which would otherwise tend to push all cores to the maximum frequency at all times. (It's new in this version, the previous 6003 lacks that option).
P.S. How are you liking your build so far?
I like it a lot! Still tweaking things - it's a long process. But the hardware you have chosen is amazing. Thank you for sharing.
I was using Euphony until recently. And that BIOS option did make a difference in my system.
However, I switched to a highly customized Windows 10 Enterprise LTSC 2019 (similar to the way you do it on the Extreme). And Windows / Roon sounds better than Euphony / Stylus for a very first time in my hobby. That has not been the case for other builds, but the finer control we have with Windows compared to the closed Euphony system gives an opportunity to fine tune things a lot better, which results in better sound quality. It's very nice to have Roon sounding good again.
Not to hijack the thread with my DIY built, which was quite challenging by the way, so all I would say is this. I have built quite a few computers - high powered, low powered, AMD, Intel, SOTA power supplies, OCXO clocks, etc. We have something very special here. I can only imagine how good the Extreme is.
P.S. I will send you a PM with something I have meant to ask you.
