How to troubleshoot memory problems.

[Flaccid Sausage]

Hello,

 

My problem is the following. Whenever my memory usage goes above 75% my system becomes unstable. Usually after 5-10 minutes it crashes, not windows blue screen but, my video output disconnects, and my computer becomes mostly unresponsive. I can't seemingly give any inputs but some processes keep working, discord for example.

 

• This doesn't happen if I have xmp disabled.
• Tried the built-in windows and 3rd party memory testers, both returned that my memory is fine.
• I have 4 dimms of 8Gb sticks, I have tried to stress all dimms individually and one stick in all 4 slots, it never crashed.
• I have tried to re-install windows, the problem persists.

I'm not sure what else can I try, what's your opinion?

What's the pc specifications?

 

I'm guessing an AMD cpu and DDR 5 ram?

Having all memory slots occupied, with XMP on an AMD cpu can possibly strangle the cpu memory controller.

It's usually better to run 2 sticks of memory instead of 4, if you want to use XMP.

 

You could try to update bios.

If that doesn't help continue to run without XMP, or if you want manually adjust the speed and test what it can handle.

Or replace the 4 sticks with 2 sticks 16gb each.

I have a 3300x, so ddr4 and on a b550 board. Do you think it could still be case, tho?

It seems likely. Your troubleshooting steps points to it aswell.

There are several threads in this forum mentioning memory problems when using all 4 slots with an AMD cpu and a higher speed XMP profile.

Well that sucks but thank you for the answer!
