Hi I overclocked my memory a months ago from 2400 to 3200 tweaking voltage and multipliers and tightened timings and got through memtest fine no issues.. This remained at this speed for around a month however when I RMA'd my 5700xt and installed my old GPU RX580 I benchmarked and my ram was showing as 2400 again. Yes I DDU'd the old drivers ect. I went back into bios and saw all my changes were still there and even in bios it said the speed should be 3200.. What has happened?
