Wierd memory errors

I've been having issues with my PC lately. It's around 3 to 4 years old, with a 10850K CPU. Recently, I've been encountering more frequent instances of this error:

"ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%p referenced memory at 0x%p. The %s operation could not be performed in memory."

The problem seems to occur less when the memory isn't running in XMP and is clocked at 2133MHz. I also tried swapping the two RAM sticks into the other slots, and it worked fine with XMP for a while, but now the crashes are happening again. I’m starting to think that the motherboard might be the issue. Do you have any other ideas on what could be causing this?

Run Windows Memory Diagnostic/Memtest86, with XMP enabled and disabled. If either detect errors, it's likely your memory kit itself. Switching the slots doesn't really test the kit itself, if the kit is bad it's going to have errors in all of the slots. If you haven't already I'd test a completely different memory kit in the system. That's going to be the best way to know if it's the kit or the motherboard. Also, I'd check what bios version for your motherboard you are on, bios updates a lot of the time have memory stability improvements so simply updating your bios to the latest version could solve the errors as well.

 

In order I'd run a memory diagnostic using WMD/Memtest, once errors are detected update your motherboard bios if it has available updates(if it doesn't skip to testing a new kit), after the update run the same diagnostics again. If there are still errors purchase a new memory kit and test it. If the errors are gone, it was likely a fix with the bios update.

Kind of fixed. I shuffled the memory around a bunch, each now slot-ram stick combination worked "stable" for a few days. At the moment I'm back to the recommended slots for the sticks and even with XMP it's been stable for the last 3 weeks.
