@foone only 7 gb? rookie numbers, gotta get those up. <3

@gsuberland @foone board/bios revision for board are my bets.

Its funny because I literally troubleshoot issues like this on almost a daily basis for myself and others. :/

@foone Yeah, like I was saying, a lot of the boards up until 10th gen were very not memory focused, so they didnt have great shielding or trace layout, you often even got really bad t topology layouts or extremely long daisy chain that would fall over at anything above 2133 with 4 dimms.

Have you looked at the bios on the board, there may be a few updates that include "improved memory stability" and usually those are extremely helpful for running dimms made well after the board.

@foone the only reason I ask is because 8th gen Intel memory controller likes to fall over when dealing with 4 sticks of dual rank memory aside from micron e die, and z1/4xx boards (6th-9th) boards were notorious for shoving a ton of sa and io voltage when all dimms were populated or xmp was enabled, and by a ton. I mean voltage that will degrade or kill the imc fairly quickly, like 6 months to a year.

@foone default uncore/ring ratio I assume. What is vccsa and vccio read (voltages, system agent and IO)? also how much memory, dual rank sticks, or single rank? 2 dimm or 4 dimm, what mobo?

@foone intel or amd? what gen? this looks legit like a cache instability issue (not cache per se, but ringbus/infinity fabric instability)
