Well, the Asrock ones aren't listed as Beta! WooHoo!! as Homer would say... and so far they ROCK! No problem at all booting up my 64GB of Gskill Trident Z (16GBx4) with it's XMP profile CL14 14-14-14-34. Before I had to increase the CL from 14 up to 18 to get it to boot... had it running at CL 18 14-14-14-34 CMD T1; now it defaulted to T2 with the XMP and every memory setting under the sun. Also looks like you can set memory speed all the way up to 4000MHZ... This could be a big deal to some people... I just like that I can now run my 64 GB at it's rated speed, might reboot one more time to try an OC from 3000 to 3200.
(Actually, I was running vanilla 2933, not 3000, which is what XMP 3000 defaulted to..., but they have an option for 3066 in the BIOS and settings all the way up to 4000)
But I need to get back to burning up my R290s with some mining...
Update: Yeah, boots no problameo at 3200 CL14 14-14-14-34 too! for some reason it set it back to T1 ( had to manually change it to T2) , probably because I manually switch the XMP profile from 2933 to 3200.
So I'm able to OC 64GB from 3000 up to 3200 at CL14... SWEEEET.... have to try OCing some other stuff too. I currently have my X1700 running at 3950 @ 1.3875v same as before this version of the BIOS.
CPU-z is showing T1 and I know I set it to T2, but maybe we'll need a CPU-Z update for it to show T2 for Ryzen Memory settings. My Aida64 eval is over so I can use it to test the increased Mem speed with CL14.
Wow, don't know if it was the 3950 setting of the CPU or what, but my real memory speed seemed SLOW. I have a RAM drive and when I tested it with AS SSD test I was only getting about 4000MB Seq. read/write. Before I was getting 7800-8300 or something. After resetting my Memory Settings again and changing CPU speed from 3950 to 4000 Mhz my Ram Drive AS SSD test was back up 8900MB/9600MB Seq. Read/Write.
Maybe Asrock's Bios aren't fully "baked" yet... Oh, well, I'm leaving it there for now and going back to frying my R290s for a few Ethereum dollars...
