Does anyone know why the AMD chipset drivers on MSI are different to the AMD ones? MSI one seems newer but totally different versions to current ones on AMD site?
Not sure. I believe AMD are slack with dropping the lastest chipset drivers I think, I'm using the version 2.10.26.336 from MSI website with an x570 tomahawk and 5800x no problems, but then again, *In a Consuela from family-guy voice* -"No... no... no.., Smiffy no nothing!"

At stock with PBO off by CPU is boosting all cores to 4450mhz and all cores to 4650mhz with PBO enabled but with PBO on its putting about 1.3v through the CPU. Is that ok for Ryzen? TBH I would rather manually OC the cpu so I can control the voltages myself but when I set a CPU multiplier the CPU just runs at that speed constantly. Is it possible to set the multiplier and have the CPU clock up to that speed when needed to downclock when idle etc? Or do I have to play with the PBO settings to achieve this?
