My understanding is that despite intel playing things down, a critical defect has been identified with Intel 13th and 14th generate that needs to be mitigated with a microcode update.  This is currently very slowly being rolled out by motherboard manufacturers, but I'm a bit worried that Supermicro and Asrock bioses won't arrive for quite some time.  

 

Is it possible to update/bundle the updated microcode with unraid? 

AFAIK it can only be applied via BIOS update, at least for now.

With most distros it's a package you install afaik, slackware is a bit different and you have to manually add it to initrd https://www.bernieland.com/share/howto-microcode_early_loading.html

 

Or is it intel dragging it's knuckles again and not releasing it?  I couldn't find the actual microcode yet come to think of it.

I read that is not going to be available for Windows, so I assumed it also would not for Linux, but I may be wrong:

Any news on how to update the Intel Microcode on Unraid/Linux?

For now you need to update the board BIOS.

There seems to have been an update this week but pretty cryptic and undocumented: https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files .  Not convinced the voltage caps are included in this ucode release yet.

If anything it seems incomplete, there was no update to the one for my 13900K.

New intel ucode but not clear whats in it

I wonder if this is the patch?  That looks like Raptor Lake patched to 129.

 

Only one of my two motherboard manufacturer's has released the 129 bios.  Top marks for supermicro, fail for asrock.

Looks like this is now official bundled:

I have to say props to supermicro for updating their bios for the w680, but AsRockRack are awful.  Abandoned their skus... Special place in hell for rotten motherboard manufacturers, particularly the price they charge!

 

Here is the repo:

I would very much appreciate these fixes being rolled into Unraid.

This should be added to 7.0.0-beta.5
