So about a month ago, I upgraded from my 2x8GB 3000MHz C16 kit of Crucial Ballistix Sport LT to a 2x16GB 3600MHz C18 kit of Team Group T-Force Dark Za. All was going well until Cyberpunk 2077 came out.

Whenever I tried to play the game, after a few minutes it would always crash to desktop. It could be anywhere from 3 minutes to 30 minutes of play. Initially I thought it was just the disasterous state the game launched in, until I found out that other people with similar hardware weren't having the same issue. Even my other computers capable of playing the game didn't have any crashing issues. Swapping my RX 460 into my main system seemed to fix the issue, but performance was too low for me.

However, recently I was trying to play Dragon's Dogma, a game I've poured hundreds of hours into before with few to no crashes, and it crashed after about 10 minutes of play. I was about ready to swap the RX 460 back into my main rig when I decided to try lowering my memory speed to 2933MHz, which I believe is the highest officially supported speed for Zen +. I then managed to play Cyberpunk 2077 for at least an hour with no issues.

Next I decided to run MemTest86+ with my memory set to 2933MHz 16-16-17-36. Surely a 3600MHz kit would have no issues at those settings. I let it run overnight while I slept.

When I came back after twelve hours, I saw this...



...9216 errors on the fourth pass. I can only imagine how much more there would've been at the rated speed. I would assume this means the memory is bad.

I'm not sure if I should try to get the kit replaced or just return it and slum it with 16GB for now. Or is my testing methodology flawed in some way?

It's not impossible that the memory can't do 2933@16-16-17-36. It would probably be a safer bet to try 16-18-18-38.

Also, 2933 is only guaranteed for Zen+ with single rank sticks. I'm not sure if the RAM you have is single or dual rank. If it is dual-rank, then Zen+ is only guaranteed to 2666.

My DIMMs are single rank. Gonna try the timings you said. Not sure why I tried tightening them up before running the memory test.

The test shows all 32G when you should run the test overnight using one 16Gb stick at a time.

Only if we are trying to narrow down a bad stick. Otherwise we want to test both at the same time.

16GB sticks and single rank? I seriously doubt it...

Check it with ThaiphoonBurner software or CPU-Z.
