I tried two memory kits and tweaked various settings, from simple XMP to manual timing settings. My AORUS B550i Pro Axe also sets incorrect timings and memory voltage when using XMP. The screenshot shows manual settings. I have just two questions for anyone who knows:
-
Why are the memory settings incorrect when selecting XMP: 4000MHz 1.4v, 20-19-19-39, and tRC 94, while the stated settings for my kit are 4000MHz 19-19-19-38, tRC 58?
-
Why is the latency so high, regardless of memory settings, and remains around 80ns?
-
Why is my motherboard's xmp so crooked?
-
With this manual setting, I start getting clicks in the sound…
