    XMP and OCing

    A quickie I suppose, and just to clarify but if XMP is engaged does it only control what the RAM does or does it include CPU controls as well?

    Also, if overclocking RAM, XMP needs to be switched off?

    Thanks

    The ram overclock will not effect the CPU settings. You need to fiddle with the SOC voltage at some point.
    Ram overclock will overwrite the xmp afaik.

    Ryzen DRAM calculator is incredibly useful ( I mean very x 3) it also includes a memory test. Thaiphoon burner if you need to have a peak at your memory Die.

    Two guides I found useful:-

    Well technically it is including CPU controls because the memory controller is part of the CPU.

    XMP is overclocking RAM, if you want to overclock beyond/differently to XMP then yes it normally needs to be switched off.

    Re: XMP and OCing

    XMP is also overclocking the memory controller,if it is above 3200MHZ with Zen2. This is why if you have a kit with XMP over 3200MHZ with Zen2,you might need to fiddle with the SOC voltage too.

    Re: XMP and OCing

    I would ignore XMP and just manually set timings - lets you control the voltages which is something I've had issues with relying on XMP in the past.
