I have this memory (Crucial BL2K32G32C16U4B) installed in a Z690 motherboard.

CPU-Z is reporting the following:

It looks like it's not running at full speed (?).

Do I have something set up incorrectly?

Thanks.

Thanks for the intel. My PC is currently tied up with a Google Workspace migration. When that completes, I'll correct the BIOS setting.

Also, I never realized that the reported speed is 50% of the actual speed.
Yep. An aspect of how Double Data Rate (DDR) is measured/reported. Just one of those geek things that has been around forever.

Well, I turned on XMP.

As far as forcing a speed, I was presented with the following (4) options:

3200 (24x100.00x1.33 G1
3200 (24x100.00x1.33 G2
3200 (32x100.00x1.00 G1
3200 (32x100.00x1.00 G2


I wasn't sure which one to choose so I left it set to AUTO.

My report now looks like this:
