hi,
i got my viii hero (non-wifi) with bios version 2702 already installed. i had all sorts of stability issues (bsod, random application crashes) that i could track to the docp mode of my G.Skill Trident Z RGB DIMM Kit 32GB, DDR4-4000, CL16-19-19-39 (F4-4000C16D-32GTZR) ram.
the issues happened about every 5 minutes with docp enabled (including triple restart loops after enabling docp in the bios) and went away when disabling docp and running the sticks at 2133mhz (default).
i did not change any other bios settings than docp, everything else is on default. i run a the latest windows 10 version with a 3080 gaming x trio and a corsair force mp600, all drivers and firmwares up to date.
looking forward to a bios version that enables my rig to run at full performance in a stable way.
kind regards,
bela
The chip only supports 3200MHz memory, anything above is OC and can't be guaranteed. Also DOCP support is sketchy. The best way to run fast memory is to do the settings for timings/subtimings yourself in the bios, you probably won't reach 4000MHz as only platinum sample CPU:s can do that without downclocking IF to half, but you can reach 3733MHz-3800Mz. Or you should reach that with such fine memory. Don't expect push one button OC, you need to do some research for yourself. The supported 3200MHz is probably very easy achievable, just turn off DOCP, set FCLK to 1600MHz, memory 3200MHz, memclk=uclk, VDIMM to 1.35V and the you can probably leave all the DRAM settings to Auto and let memory training do it's job during boot.
If you wants to clock higher Ryzen Dram Calculator by 1usmus is a great tool to find good settings, you need to use Taiphoon Burner first to get your exact ram specs and then feed them into RDC as a html/xml-file.
If you have a Zen 2 you can also use Clock Timer for Ryzen also by 1usmus to get most of the job automated, Zen 3 support will come soon
