Hi all,
Thought I'd post my experiences with my new ROG Zenith Extreme setup.
I built a complete system with new components. Threadripper 1950X with Enermax TR4 360 rad and ROG Zenith Extreme, of course. For memory, I got the only 3600 MHz RAM On the QVL. Matched set of 3600 MHz Corsair Vengeance 4 x 8GB Sticks.
I tried to apply a D.O.C.P. profile, but the PC refused to boot with that set. Eventually, I got the RAM running on the manual 3466 settings. No stability issues at all at that speed. Setting 3600 made the PC unbootable. Opened a ticket with ASUS. They suggested I run MemTest86. It failed on Test #8 consistently. RAM is in A1/B1/C1/D1 as the manual asks for. The CPU is set at stock speeds, no OC. BIOS is latest release version. If I try to adjust RAM speed up in to 3600 in Ryzen Master the PC resets back to stock before booting.
They then suggested removing all RAM and testing each one individually. With one 8GB stick in, I was able to set the D.O.C.P. profile at 3600 and tested all four RAM sticks successfully at 3600 MHz level, passing all tests. I put all four DIMMS back in (I rotated all DIMMS to different slots) and was able to keep the D.O.C.P. 3600 MHz profile on boot. However, when I run:
"wmic memorychip get speed" in a CMD window I see:
speed
3466
3466
3466
3466
Tech support suggested I clear CMOS which is what I will do tonight, but has anyone run into this before? With each DIMM passing individually at D.O.C.P. 3600 I'm suspecting a BIOS issue.
Cheers.
