Looks like all the new BIOS/UEFI files are here: http://www.asrock.com/support/index.asp?cat=BIOS
stree, and looks like 4.50 not 4.60.
Enjoy, John.

Upgraded from 3.0 to 3.4 to 4.7 on my AB350 K4 Gaming today. Probably being way to over cautious but I did a full 15 min power dc'd/battery out/jumpered bios clear between each bios flash and everything came out great...I wasnt having any issues before I flashed but I did it anyway. Tridentz 3600 still capped at 3466 :-(

@Handrox, reading on the forum link you've given to us. It seems your the only one who is complaining the latest BIOS. 

They response your post but they didn't complain it to their system.

no, there are others with the same problem. There are postings before mine that have already reported this problem and later also, there were those who posted improvements in transfer rates and latency, but with cpu in stock, with overclocking the problem appears.

I have a pair (2x8GB) of Trident Z 3600MHz CL16 and also use at 3466MHz, I can not stabilize 100% at 3600MHz, let's say it's stable about 90%, giving random crashes on everything in games. Ja 3466MHz CL14 is 100% stable and I am using it for months ...

Maybe it's some sort of a stability issue then. In any case, I had a chance to check my numbers and on my system (at its current settings) the benchmark results were actually very stable. Five benchmark runs and memory read was always 46xxx, memory write 45xxx, and memory copy varied around 400 points. The latency mostly varied between 77.7 and 77.6 nanoseconds, but one result was 76.8ns, so even more notable outliers are possible. The latencies of L1-L3 were rock solid on these settings and generally the variance was very small, except for the L3 results, where transfer rates for L3 read, for example, could vary between 257.xx and 325.xx. In short, something really weird is going on if 4.60 drops your figures by that much. I assume you double checked that the timings and everything that were set in the BIOS also showed up with other programs like CPU-Z or Ryzen Timing Checker?

By the way, 3466MHz sounds about as good a memory speed as you can get with Ryzen 1. Even 3200MHz is a good result and may be tough to achieve without Samsung B-Die memory.

For testing purposes how would I go back to an older bios? I just tried to go back to 3.0 with the dos installer and it would not work? Do I need to flash back to 3.4 then back to 3.0?
