Don't know what hit me today but I decided to run MemTest86+ 5.0.1 (after running MemTest86 8.3 UEFI) on my Ryzen 7 3700X system. It reported a single bit error for test 6 (Moving inversions, random pattern). I was surprised so much I ran this exact test three more times - no extra errors were reported.
I presume it was a cosmic ray which flipped a single bit but in my 25+ years of using PCs this has never happened before.
How do I know it's a single bit? Check the image:
0xfd and 0x7d differ exactly in one bit.
In binary that would be: 1111 1101 and 0111 1101.
Have you ever experienced anything like that?
