Question System crashing, games not loading - memtest86 passed

[greigm78]

Evening all,

So my system has been randomly crashing, initially during gaming but now it's crashing when starting games, the "help" link says memory fault or failure. I initially thought it was the GTX 1070 I had, so replaced this with a RX 5700 XT Pulse from Sapphire (which isn't as good as the 1070 on Wildlands IMO, get some screen tearing that I never had before).

I ran 4 passes of Memtest86 and it got through all 4 passes in a little under 4 hours but with 0 errors.

I don't know where to look next, any advice?

System:
CPU: AMD Ryzen 5 2600
MB: MSI B450M Mortar
RAM: Corsair Vengeance Pro RGB 2 x 8 GB DDR4 3200Mhz (XMP Profile 2)
GPU: Sapphire Pulse RX 5700 XT
SSD: 2 x WD SN500 NVMe
HDD: Toshiba 2TB 7200RPM 64MB Cache
Case: In Win 301 mATX
PSU: EVGA Supernova G3 550W Modular

Hi.

Go to your BIOS, disable the XMP profile on your RAM and try again.

What is it that I am trying again? Memtest passed with 0 errors on XMP 2

I usually let memtest run overnight, on the DDR3 it goes through 10 different tests to make 1 pass.

Each pass was 14 or 15 tests. Whole thing was just short of 4 hours. No errors.
