Hi
I have 32 gbs of G.SKILL Trident Z Royal Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 4000 (PC4 32000) Desktop Memory Model F4-4000C16D-32GTRSA

In bios I've turned on XMP profile 1, and it shows as if it's running at 3999 Mhz

On desktop, within task manager, it still states speed as 2133 Mhz

In CPU-Z DRAM frequency is at 2000 Mhz. Does this value get doubled to 4000 Mhz?

Which one is correct?
Intel Core i7 11700K (didn't do any OC yet)
Gigabyte Z590 AORUS ELITE AX
EVGA NVIDIA GeForce RTX 3090 (no OC)
Thank you
 
Solution
If the CPU-Z is telling you its 2000Mhz then its probably accurate. Sometimes Task manager likes to report false data.

Fixed that for you. CPU-Z tells the base speed. DDR stands for Double Data Rate, so a base rate of 2000MHz is actually running 4000Mhz.
