About 2 years ago i built my PC with the ryzen 7 1700x, gtx 1080, and gskil trident z 3200 ram (F4-3200C16D-16GTZR) on the asrock x370 taichi. While these ram sticks aren't necessary specified for amd builds, i was able to have it run at 2933 or 2800 with a bios update. Fast forward to this day, my pc wont boot for some unknown reason so i had to click the clear cmos button, now when i turn up the ram speed the pc just will not post so i have to clear cmos again. Is there a reason for this, why could i have increase the ram speed before but now i cannot?
