It didn't brick it like others but it was glitchy and Windows threw errors. I replaced the mobo with a Killer ac/sli because I was refunded instead of replaced, which was fine because of the Taichi shortage. All other parts are still the same. Hardware AMD Ryzen R7 1700 x370 Killer ac/SLI (Bios ver 2.30) Nvidia GTX 970 4x8GB 32GB Team Dark 3000MHz Ram @2667MHz  AMD R7 240GB ssd Toshiba P300 3TB hdd Nzxt Hale82 V2 700w (Also used a Rosewill Hive 750w psu) Win 8.1 Pro x64 Everything had been running fine for nearly a month. All of a sudden the computer started to constantly BSOD, Memory_Management and IRQL_Not_Less_or_Equal errors. I've been using memtest86+ for the last two days and found errors on 3 of the Team Dark sticks. The one good stick I have was further tested in the other DIMM slots. At this point I assembled everything and switched to the Rosewill PSU just to eliminate that possibility. Again, the computer still BSODs or freezes on the desktop. Memtest still reports that the single stick is good. Bad CPU? I just find it strange how out of the blue 3 memory sticks simultaneously go bad. Any further thoughts or insight is greatly appreciated. Thanks

What was the DRAM voltage set to in the UEFI/BIOS? Or the SOC voltage and SOC LLC setting? Just using the Auto values? You can check their values in the H/W Monitoring screen.

So the problems you had with your X370 Taichi were completely different than the BSODs you were getting with the X370 Killer SLI/ac?

Did you happen to run Memtest when you had the memory in the X370 Taichi? My point is the memory might have had problems out of the box, and since you have 32GB, the bad memory chip/area was not used until recently. Or one at a time the DIMMs began having errors, and it was not until three DIMMs had errors that the BSOD issue began happening. Electronic component failures tend to happen early on in their usage if they have some internal defect.

Did you happen to try running the memory at say 2400, and then run Memtest?

You could test for a failing memory controller by putting the memory in another PC that uses DDR4 and running Memtest on it, if possible.

I have the same board, with a 1700X with G.SKILL FlareX memory, and I do not get random BSODs.
