Question WHEA id event 19 error

[Detrox00]

Hi, after two months of not touching my PC I started to notice drops in fps in gaming, doing stress tests with OCCT detected the WHEA error. However, the PC does not crash even in games or under stress. I have no overclock or xmp active, already updated bios and changed psu. For the ram, I ran memtest86+ but for only one cycle.
Hwinfo show "CPU Cache L1 Errors".

Please help me for two days I've been running tests and reassembling the PC but I haven't solved anything. I want to understand the faulty part in order to change it.

The intel have a tool called

Intel® Processor Diagnostic Tool​

you can use that to if have a problem or not.
I have at least one XEON that gives some kind of error. I have clean the cpu pads with a small paper and reseat it. And become working again. (That is the Ultimate Option).

I passed the intel test without any errors. Do I still have to clean the cpu pads?

If that show no problem not need
Maybe you have a memory problem.

Did you clean the ram? Maybe can solve some of your problems.

I replaced the ram but nothing changed. 🙁
