I just submitted an email ticket to AMD but after reading through some of the threads here and seeing the responses, I had a couple additional questions I thought I would ask here. I am getting the random freeze / hang issue (not BSOD) that many people are having, that can only be solved by a hard reset. The system just freezes, mouse disappears, etc., almost always under normal circumstances like browsing with Firefox (not gaming). I've seen a couple threads here where people are talking about tweaking various BIOS / motherboard settings, and I wanted to ask how I should specifically go about them with my motherboard (ASUS B450 Tomahawk Plus).
The things I have seen suggested and would like to know how to do are:
- Disable Global C-States (could not find option in UEFI)
- Set power supply idle control to Typical Current Idle
- Manually set DRAM Vcore (don't know what this is)
- Set CPU Vcore loadline calibration
- Vcore SOC loadline calibration
- Best way to flash new BIOS on my Asus motherboard
I've pasted what I submitted to AMD below and would be interested to know if anyone has any other thoughts or tips. Please let me know! Thanks
Quick update: I found the Disable Global C-States and set power supply idle control to "Typical Current Idle" options in the BIOS and changed them. On reboot the computer froze immediately. So I rebooted and reverted to default settings. Going to try to flash a new updated BIOS to my motherboard now. Other than that I'm not sure what else to try.
Well, I figured it out. Going to leave this up in case anyone else has the same problem. For me, it turned out to be the RAM speed. I guess Ryzen processors basically need the RAM to be as fast as possible. My RAM was rated for 3000 Mhz but was running at like 1600 out of the box. Going into the BIOS and turning on the default DOCP profile boosted the speed up to 3000 Mhz (and automatically adjusted a bunch of other settings like SOC voltage) and I haven't had the freezes at all since. Hope this helps if anyone else encounters the same issue.
