I have a big problem with my Ryzen 2700X and B350. (RAM G.Skill Trident 3200 - XMP profile 2)
Basically, CPU downclocks under load. I noticed my problem in CSGO. With 1070 i only have 150 - 200 fps (LOW Set), so i decided to test CPU in Cinebench.
Performance is dramatically low - 350 pts. CPU load during the test was 20% and clocks decreased from 3.7 to 0.8 :/
B350's BIOS is updated and I have tried reset settings even with battery out. Still nothing. Please Help
