Released TODAY 1/16/2018
New "Bridge BIOS" 3.50 to flash prior to upgrading to the new 4.50 "Update AGESA for upcoming processors."

I'm not gonna touch these.  Waiting on the microcode updates and websites testing their performance impact on X370 Ryzen systems prior to flashing.

just flashed it - my gflaresx can now boot with 3333 instead of 3200, but now its unstable at 3200 which wasnt before. Memtest64

also dram voltage change is not working so i'm locked at 1.35 which probably is the cause of 3200mhz instability

Nothing new. Some options for the pcie. The voltage of the dram is reset when entering bios at 1.35v and the pstates continue to fail.

went back to 3.40

this bios(4.50) is a mess: 

DRAM voltage change doesnt carry over from bios to windows
to get pstate oc you need to switch the oc mode to amd cbs but then you lose xmp settings
manual timings are mixed with hex or some sh*t
couldnt get anything stable out of this bios which works with 3.40
but bios stability, ie not having to jumperreset once was good

Thanks everyone for testing and reporting back!

I personally wouldn't touch new ASRock releases until at least a few months, and positive feedback of some brave souls!

I confirm it. Pstates work well with amd cbs but the ram does not.
