New Microcode to further enhance AMD Ryzen memory compatibility
AMD will be releasing a new AGESA microcode update this month, this is now being worked on by the motherboard manufacturers. The new microcode (which is located in your BIOS) will further enhance memory compatibility.
This news has reached us by way of Gigabyte. A technical marketing employee has been explaining that AGESA 1.0.0.6 for Ryzen processors will enhance memory compatibility with high clocked DIMMs and would open up 20 new memory registers.
Gigabyte employee: Wish I could drop in and give you guys a new BIOS but I don't have them yet. Latest word is they are working on a new set with AGESA 1006.
Just to recap these are the issue being worked on:
- For those looking for IOMMU fixes we are hopefully going to have an option to force boot off a specific PCIe slot. Its not the grouping fix, but a work around for now.
- Disable LAN (Per request)
- Disable Audio (Per request)
- "ROM Image update" (Being worked on with AMI, no ETA)
- Cold boot / Wont boot. Have to re-flash BIOS. (people have referred to this as "soft brick")
- AGESA 1006 - improve memory (Got high hopes for this one. Going to enable 20+ memory register)
That means there will be another 20 memory kits added and supported. AMD back in April already released AGESA 1.0.0.4a which brought slightly better performance, lower memory latency and also increased memory support as well as faster bootup (post) times.
As you can see AGESA 1006 is in the works and should see the light of day with initial Beta BIOS updates soon. Btw the Gigabyte employee mentions AGESA 1006 twice, he could actually mean 1005 as the last AGESA release from AMD was 1004a.

That's wrong actually. Last update was on May 11th. Ucode updates are necessary for Intel users as they are proprietary code and they aren't included in the kernel, unlike AMD's microcode.
Updating the microcode doesn't do anything for Linux with Intel as it's only for older dual cores. The strange thing is, I've never ever heard of Microcode before up until a week or so ago. But I have seen Windows 8 Microcode updates when I searched for it.

All I know is it hurts my brain thinking about the complexity of it. But it's something I have to find a route cause to in my case.

The actual update attempt isn't anything crazy. You pretty much download all the files in the same folder as the "install.bat" of the VMWare utility and you run it.

I understand that part. The Kernel being the part that handles it all. But it can give errors that can't be fixed by microcode. I'm delving a little deeper. I could be wrong though.....
Microcode can be either part of the OS or the bios. It is essentially, the CPU "driver".

I have no idea how Windows handles microcode updates. For Linux AMD's microcode is in the kernel itself, and Intel's microcode is a separate file/package that is being loaded from the bootloader.
EDIT: I also found this interesting post, which I didn't knew could work.
