It depends on the clock speeds - I've gotten 2933 to run at 1.10 SoC Voltage and a little more open timings. The latest BIOS on their webpage is 1102, I've been using a beta version that people have claimed to have a lot more luck with - 1107. At first, it was extremely unstable at all different combinations of timings, SoC Voltage and DRAM Voltage. It was showing temperatures all over the place - I would up the clock speed of the ram and my CPU temperature would jump ( I assume it was possibly upping the voltage to the CPU). I finally set my SoC Voltage at 1.1, set my CPU Voltage to 1.4 and Dram to 1.4 and was able to get 2933 stable. It's just overall a pain in the ass to deal with if you have ram speeds higher than 2400 and not Samsung B dies. In the coming months, it will get better with new BIOS releases (ASUS has only released 2, last one on 3/29.) I've read a few articles of people being able to obtain 3200+ but wanted to see if anyone else has tinkered around with the Ryzen.
They are a great CPU overall, A+ for the money and speed.....now it's just the wait for compatibility. I think the problem stems from only being able to adjust 4 of the RAM timings versus Intel CPU's that allow you to adjust all timings.
