WIndows 10 DRAM Speed not shown properly.

I have 4 banks of 3200 DRAM's in my desktop. But in the BIOS as well as Task Manager, they reported 2133.

Should I correct it, and how?

Thanks.

Use the Memory tab instead.

Windows doesn't always read the speed correctly. CPU-Z should have '1600 MHz' as the real clock since DDR is rated for its effective clock.

If you never enabled XMP or anything it's likely the speed from the JEDEC table on the RAM and would show 1066 MHz, which you'd have to go into BIOS/UEFI and set.

Open cpuz again and click on the memory tab. What does the nb frequency section say or even the dram frequency box? As long as it says 800 or close to it for the NB and 1600 for dram then you are running at 3200mhz.

I went to BIOS and change the DRAM frequency to Auto. Still got the same CPU-z reading.

This is how my BIOS page looks.

That means you are running 1066mhz. What options are available for the load xmp setting? Also dram frequency? Although it does say profile 1 is enabled. What bios revision is installed?

What options are available for the load xmp setting? : Auto or XMP 2.0 Profile 1
There is no mention of enable/disable.
The BIOS version is ASRock 3.3

XMP Profile 2.0 will apply the speeds of the sticks, as well as timings and voltage.

XMP values extend beyond that of the JEDEC specification, so you have to enable XMP to apply the profile values of the sticks to the system. Selecting XMP Profile 1 will do what you want and up the RAM to 3200, but it will also apply the correct voltage for those frequencies as well as the latency values (timing).

Changed the to 2.1 Profile and nothing seemed changed.

I am wondering what the 4th column in the "Timings Table" mean? Does it meant 1600x2?

Wrong tab, that tab shows you the JEDEC speeds/timings as well as the XMP profile values. The Memory tab shows you the current clock speed.

Anytime I click save change and exit, the machine would go on and off a few times before the screen lights up.
That's pretty standard when you make changes to the BIOS. Especially if it's memory related as it's likely retraining the memory. Is it doing that on every startup now?
