I do not know enough to validate it. I had issue in past - one pin (not on CPU, but hole on AM4 socket) was damaged, and it made pcie-express x8 from original x16.Yes they were. I mean if they weren't it shouldn't just affect L3 cache? I should be running into BSODS or other stability issues and my other scores would be bad too? I get the same performance as other in CPU-Z, TimeSpy, Cinebench R20. It just AIDA Cache test giving me this... My ram is in 2 and 4 slots (from CPU) like it supposed to be
Here is my timings:
After fix, it was ok again.
So, if some pin is responsible for how ram communicates with CPU/L3... with on of lines is damaged, why it could note behave this way?
But if is something wrong with your CPU, I think it will be issue with infinity fabric between SOC or controller. And L3 will act the same in different PC.
But I hope not. I hope when you change your RAM, completely reset CMOS etc., you will have appropriate speeds.
Good luck.
