I also have random freezes with Asus Rampage VI Extreme (not Encore/Omega/etc) at latest BIOS (3701), Intel i9-10980XE, and a kit of 4 matched 32GB modules (G.SKILL F4-2666C19Q-128GVK RIPJAWS V). At times they occur in less than 1 hour after boot. I tried with increasing RAM voltages, VCCSA, VCCIO, manually lowering RAM frequency instead of XMP, moving the RAM modules around (all to the left, at A1B1C1D1, etc), nothing has worked so far. Checking with a memtest86+ iso gives errors after a while, at 96GB mark. I hate this motherboard.
Would going for 8 RAM modules instead of 4 improve stability ?
