Question Strange Ram issues


Sep 8, 2018
I've been having some weird ram issues that I'm looking for an answer for.

PC Specs:
Cpu: Ryzen 3 2200G
Gpu: RX 580
RAM: Corsair Vengeance 2x8 DDR4 2666 (One has been troublesome)
Motherboard: Asrock ab350 pro 4

Ok so there is one stick of ram that has been causing me some trouble and one stick that has been totally normal. For the past few months I've been running my system with only the good stick of ram (in slot A2, as the manual instructs). When I insert the "broken" ram into B2 my system boots normally and says I'm running with the full 16gb, but it seems that if there is a spike in ram usage or increased computing needs (such as trying to play JC3) I experience crashes, freezing or blue-sceens. If I shuffle the 2 sticks into different slots I don't get any good results.

When I use the good stick only, in any slot, it works normally.

When I use the bad stick only, in any slot, I get an infinite boot or boot loop.

I've tried changing the XMP settings in bios, no difference.

The strange thing is that I've run memory tests that have not found any problems AND I've given the bad stick to my friend to test in his pc and he found NO issues at all.

Anyone have any idea what to do?
