I have a Ryzen 7700X setup with 32GB of DDR5 RAM, rated at CAS 36, and I'm using a Gigabyte B650 motherboard along with a 9070XT GPU. I've enabled XMP 1 in the BIOS, and even though Ryzen Master indicates it's on, the memory clock is displaying as 3000MHz. Can someone explain why it's reading this way?

Just to clarify, 6000MHz doesn't technically exist as a number for memory; it's referred to as 6000MT/s. Since your RAM clock is set to 3000MHz, it’s perfectly normal because that's how DDR works. For every cycle (3000MHz), you're getting two data transfers, which adds up to the 6000MT/s.
The reason you're seeing 3000MHz is that it's actually 6000MT/s. RAM manufacturers often mix up the terms, and many software tools will show the effective clock as half the rated speed because DDR (Double Data Rate) memory sends data twice per cycle. So, your RAM is indeed running as intended!
Totally! The memory speed shown in monitoring software is correct. If it reads 3000MHz, that's just the base clock, while 6000MT/s is the total data rate due to DDR technology. Everything's functioning as it should!
Thanks for explaining this! It's confusing how the terms are tossed around.
