Good Morning,
sorry at first for my English. I hope you understand my problem 🙂

I bought the ASUS Rampage V Extreme with Corsair Dominator 2800 Mhz.
Before buying i checked the manual to check if the Mainboard works with the RAM.
My CPU is I7 5930K. After installing i start my computer and the information screen shows me DDR4 2133mhz and not 2800mhz

Has someone a idea why this happened ? I updated the BIOS to 1201

You need to enable XMP or set the memory speed manually in the bios.

Hello,
yes. this i understand. But then in Window the memtweak software says 2800 mhz.
But the start screen from my computer says 2133mhz. What is correct then ?

Use CPU-Z and look at the Memory tab. Take the DRAM Frequency and multiply it by 2.

2800 is correct, that's just how it is on this platform
