Thank you very much for contacting the Intel® Communities Team, Klass-2.

 

 

Allow me to share with you that the microcode update will be provided by your mainboard manufacturer by a firmware update, please get in touch with them so you can get this update for your system. Additionally, Microsoft® began to distribute CPU microcode updates as well, please find more information about this in the links below:

Hi,

what I am saying is that the CPU is missing in the update guidance pdf (https://newsroom.intel.com/wp-content/uploads/sites/11/2018/03/microcode-update-guidance.pdf )

and while the latest linux microcode (not using windows) includes updates for other broadwell cpus it does not update the microcode for the E5-1620 v4 (06-4f-01)

using a bios update is not feasable for me at the moment

greetings

Hello, Klass-2.

 

 

I am sorry for the misunderstanding. In this case, we do not have this information yet, please continue monitoring the information updated in the https://newsroom.intel.com/ Intel® Newsroom, we will post that once we have this update available for your processor.

So I think the update for this cpu was posted with the latest microcode Update but it was marked as "Special release with caveats" - I see in the readme patches for the linux kernel to use this but what about Other OSes? I'm using this CPU with freebsd aswell.

Hi Klaas-2,

 

 

Intel released the newest Microcode version for Linux* last April, 25th. This version supports any Linux flavor. The Intel® Xeon® Processor E5-1620 v4 is included on the list.

 

 

Linux* Processor Microcode Data File Version: 20180425, Date: 4/25/2018

 

https://downloadcenter.intel.com/download/27776/Linux-Processor-Microcode-Data-File?v=t

 

 

Note:

 

Intel recommends getting the microcode using the OS vendor update mechanism.

 

 

Regards,

I think you may have misunderstood my question. I wanted to know what the caveats mean for using the microcode with FreeBSD, it's not a linux.

Hi Klaas-2,

 

 

I am sorry for the misunderstanding. Please allow me 24 to 48 hours to get an answer from my upper level. The documentation available about FreeBSD* is limited.

 

 

In the meantime, I found a workaround from FreeBSD support. It will be a great test in order to update the microcode of the processor.

 

 

4.2.3 What is microcode? How do I install Intel® CPU microcode updates?

Hi Klaas-2,

 

 

The latest microcodes released are already posted at downloadcenter.intel.com. Each version indicates which operating system will support.

 

https://downloadcenter.intel.com/

 

 

In the case of FreeBSD we need to wait for a newer version, my suggestion is to keep watching our website for newer releases.

 

 

And give a try to FreeBSD workaround.
