It was already known that there would be further microcode patches. On X299, I've not experienced the random rebooting they're alluding to so I'm in no rush to upgrade again.

I wasn’t aware of that.*

That would be due to the Microcode in the 1102 BIOSes being version 200003A

I did well not to flash the bios, Intel recommends the manufacturers to remove the bios with this microcode 😄

Indeed it may be that, but I saw that it was the microcode 3C that bypassed the vulnerability (it is not corrected), so the bios 1102 will not do it?
Sorry for my english 😄

Skylake-SP

STOP deployment of these MCU version 3A/3C

Continue use of these MCU versions 39

For Skylake-X, I see that

70875

and the version before is 2B, no 39 😉
Skylake-SP (Xeon) is for datacenter/workstation

Skylake-SP=Skylake-X(Same architecture)

0x3a, 0x3c=200003A,200003C

Why STOP deployment of these MCU versions?(3A/3C)

It will surprise me that you can put a Skylake-SP (LGA3647) with an MB for a Skylake-X (LGA2066), so it's not the same thing
After just read the Intel pdf, nothing complicated

Skylake-X, microcode 3A used (3C stopped)
Skylake-SP, microcode 39 used (3A/3C stopped)
