Question XMP profile not working

[Stephen thicc]

I have been trying to fix this issue for days, I have 3000MHz RAM (2 X 8GB correctly running in dual channel) and I have been trying to get the XMP profile to work that allows them to run at their advertised 3000MHz.

When I apply the XMP profile in the BIOS it does not change in Windows, task manager still says 2133MHz and CPU-Z says 1066 (I know you have to double that number, making it 2133).

I have tried changing all of th values manually and rebooting, still the same effect. I changed the RAM positions today, still the same, and I have tried using Ryzen Master to put in the correct timings which also didn't work.

When I go into CPU-Z the timings it displays for the RAM is the stock ones for the RAM and not the ones I applied in the BIOS.

I updated to the latest BIOS today and updated the chipset driver to the latest also.

Any help would be appreciated!

Does BIOS confirm new frequency ? If you turn off Gigabyte greeting screen you should see the frequency displayed for few seconds while starting. Windows may not show correct frequency, only starting frequency but CPU-Z should. Also make sure you have RAM in proper slots, I believe they should be in A2 and B2 but do check MB manual.

I'm guessing your question is about using two CMK8GX4M1D3000C16.

Memory modules sold as Singles have no guarantee to be compatible in any configuration other than as a Single module.

Use of exact match, same thing, identical have no guarantee to be compatible together.

They were bought in a kit

I tried the RAM in both dual channel configurations but it didn't change anything. How do you disable the greeting screen?

Update:
I just tried setting my XMP profile to 2, this changes my RAM frequency to 2666MHz in the BIOS and in Windows.

I tried to switch back to XMP profile 1 and it just resets it back to 2133MHz. This is getting weird...
