sTRX4 can take one of three CPUs ranging from 24 to 64 cores. The TRX40 Aorus Xtreme that's mentioned in the thread should be the absolute top of the line even if it was launched before the 64 core monster was available. So I'd expect it to work just fine with the 3970X which is a 32 core part.
But I wonder if this is a Gigabyte issue who have a history of playing around with the power delivery and using "fake phases" (to the point where they now have to advertise their boards as having 16 "real phases"). As far as I can tell many (most?) reviewers benchmarked the board with 24 core CPUs and most likely skipped on the power intensive tests.
- franzb 7y agoThis mobo has 16 real phases, according to BuildZoid's analysis.
- close04 7y agoI imagine it is. I meant they had such issues in the past (hence the "this time for real" approach) so it may be that they cut different corners in order to meet some other targets that are marketable.
- leeter 7y agoTo me this smells 100% like a transient issue, Gigabyte probably assumed that more phases would wipe the transient response time out. The issue is that if you're shutting down phases as Buildzoid mentions you'd have to do to get efficiency; you then lose that response time advantage until the phase is spun back up which is the longest part of the power system cycle. Normally output filtering is designed to make up that gap, but I think in the case of these chips that's not happening. I suspect it's a lot more complicated because I have a sneaky suspicion that adding more caps wouldn't solve the problem (completely).
