New AMD AGESA Microcode in the Wild & New UEFI

I am getting back information this morning from motherboard builders that new AMD AGESA microcode has been released and we are now seeing UEFI/BIOS files appearing on manufacturers' websites. So if you are a Ryzen owner, I would highly suggest checking for new UEFI today and getting that flashed appropriately. Hopefully this will address some of the RAM compatibility issues we have seen. And as always, we suggest flashing the UEFI from inside the UEFI, not inside your OS. Also keep in mind that these newer UEFI do not always flash like older BIOS. I suggest flashing UEFI from a USB flash drive. Leave the flash drive in the system and leave it alone until you see the system back to the desktop, or back in the UEFI with instructions on what to do. The trick here is to NOT remove the new UEFI files until you are 100% sure the system is finished with the files. It is not unusual for this to take a "long time" with these newer UEFI systems, and it is very likely that you will encounter some reboots during this process. I mention this as I know many of you have been putting off new system builds for quite some time, and while UEFI is certainly more robust than the old-time BIOS, it does things a bit differently than you might be used to.

I would clear the CMOS, reboot, set optimized defaults, and then reboot again. Full power down, and then flash your UEFI. Good luck!

AMD Generic Encapsulated Software Architecture (AGESA), is a bootstrap protocol by which system devices on AMD64-architecture mainboards are initialized. The AGESA software in the BIOS of such mainboards is responsible for the initialization of the processor cores, memory, and the HyperTransport controller.

Nice. Any news on fixes? Perhaps a fix to the ram frequency issues people have been reporting...

Edit: Derp. I can read I promise.

Nice to see stuff like this out already! Sounded like AMD was planning on getting this stuff out in May?

I am sure they want this stuff out before the Ryzen 5's hit the market, as those are where they are expecting the gaming bang for the buck to come through. In fact, I would not be surprised to find out the R7's were an intentional rollout to use early adopters as guinea pigs, in order to find any holes that needed patching prior to the main gaming lineup (Typical AMD Marketing notwithstanding).

If the R5s can handle higher clocks and have the new architecture bugs ironed out, I think we could see some good things here.
 
I'm assuming some benchmarks won't be far behind once this is fully fleshed out? Not expecting world changing, but would like to see some incremental boosts from anything like this.
 
This is why I'll forever be buying mobos with dual BIOS/UEFI. I made the mistake of flashing from windows once and thought I lost my build. Dual BIOS to the rescue. 100% behind switching to secondary BIOS flashing that and don't switch back until the next upgrade and repeat so you always have one working while getting updates to the other. Or just keep the original and always flash the second one but that can be fun when you have RAM that needs a bit extra voltage and it won't post.

I am going to suggest that this update has nothing to do with IPC.
 
Nothing on the ASUS site yet for my Prime X370 Pro, hopefully it will help to get my memory above 2133mhz when its released
 
Thanks for the heads up on the UEFI quirks. It's been f*cking 6 years since I've built a new rig. Hell, I'm at the point where even if I didn't need to replace the current box, I'd have to do it on enthusiast principle alone.
 
No issues flashing my board but I cant tell it helped. Maybe they'll dix dual rank DIMMs next time around
 
Also don't assume that one uEFI flashes like another one. I have 3 different uEFI devices and they ALL have totally different update procedures.
 
hopefully this addresses the slow post times im seeing with the msi x370 carbon. the last bios update from msi let me run my memory at 2400 so now its just the longer than normal boot up that is annoying.
 
Hmm, that's... interesting, I must not be understanding the other blog post that came out from Robert Hallock on the 13th (Tips for building a better AMD Ryzen System) - under "step 7" Robert says:



So, this UEFI update only addresses RAM compatibility and what Robert mentions is just specifically for RAM support for higer speeds (thus being two different and... somewhat unrelated items)?

You would need to ask Hallock about what Hallock's statements mean. I have not discussed this with him.

This is not a UEFI update, board makers are responsible for those. AMD issued a Microcode update to board makers. And I am telling you that some RAM compatibility issues should be addressed in this AGESA update.
 
I guess that's where my confusion is - UEFI and microcode/AGESA update are not the same things :) (edit - helps to look up terms heh :p) - Well, hopefully with all this stuff combined it'll help the existing and future boards operate... well, as they should? heh!

Can someone help me add simply this 1 microcode to my bios? fx 8100 CPUID 600F12

I'm sorry, I am not very skilled in this particular type of computing. I don't know how to check the AGESA version?
