Whea-logger event 19

I am getting these warnings in the event viewer for about 1 day started at 3:00 at night, now seems that these errors have stopped when I updated Windows 10 to newest version 16299.214.

Look at the photo, apcid,errortype




Why I am get those warnings in 21 january? I used windows 10, build 16299.15. Now these errors stopped and not showed in weeks on 16299.214 build.


Also my PC is i7 8700K 4.7Ghz (multiplier) ,stock bios,ram XMP GSKILL 3000MHZ 16GB DDR4


I tested my in benchmarks and games. No problems. No bsod, no crash in games, no shutdown, nothing.

Also, I have tested my ram in memtest86 and ihcmemtet no errors.


So, can anyone tell me what is that WHEA-Logger 19 ?

Today is 12.03.2018. Not single Whea warning. It happened only in 21.01.2018.
So still it was something with hardware ,change something in UEFI or leave it ?

These may have been Microsoft windows updates related to Spectre and Malestrom.
I too had them on my computer and they have disappeared.

I installed from USB MEDIA BOOTABLE ISO version 16299.15 ( its build from october 2017 before meltdown / spectre ). And that was version before spectre/meltdown.
