   The Ryzen 3k bios(5.50) for the X370 Killer SLI/AC is missing the LLC settings. Because of this my overclock is no longer stable.  Which is pretty annoying as I require every bit of performance as possible from my rig for work.  The difference between 3.7GHz and 4.0GHz on my Ryzen 7 1700 is massive in my workloads.

Hopefully they'll add it back as that's kind of an important part of having a stable overclock on any CPU.

I updated even though I don't have a ryzen 3k processor because of the ability to OC the FSB Therefore allowing better OC especially with single core.  My MoBo was perfect with the 5.40 BIOS.  Now i'm stuck on 5.50 after RMAing my board for a power delivery issue.

	I agree. I only updated to BIOS 3.40 with my 2700x and have no issues at all. I did this for when I'm ready to buy my 3700x (no more 3900x I don't need it). With 3.40 I can just put the 3700x in and upgrade again to a more stable BIOS. I'm in no rush to buy a 3700x I will most likely buy one toward the end of Sept early Oct when all issues should be ironed out.

	As I am sure most of you know by now, Ryzen 3000 has launched and there are BIOS updates available to support it. As with second gen Ryzen launch I am seeing a lot of first and second gen Ryzen users updating to the latest BIOS and having issues with their systems. Please guys, if you are not upgrading to Ryzen 3000 DO NOT UPDATE your BIOS at this early stage. In a few months all these teething issues should be resolved and you can try out the latest BIOS version if that is of interest to you. Generally speaking, if your system is working as intended and you do not have issues with the BIOS then don't update. Ryzen in particular is a fickle beast that is prone to issues from one BIOS version to the next. Most of the changes in the new updates are explicitly to add Ryzen 3000 support and will have absolutely no benefit to first and second gen Ryzen systems. This advice will likely apply for all future Ryzen launches and even to intel systems when a new CPU range is launched on an existing socket. Edited by Xaltar - 16 Sep 2022 at 5:17am
