I just bought a 32gb kit of 2x16 corsair vengeance rgb pro ddr4 3000 MHz c15 ram, I set the xmp profile, and it set the cas to 16 and the command rate to 1, does anyone here know why, and how to get the cas back to c15?

Free and easy to use. Once picture is uploaded click on it and you'll have a column to the right popup, click copy direct link and paste the url here using the image button next to the smiley icon

I see, thanks. XMP profile under spd tab does say they should be running CL15. Differences between CL 15 and 16 isn't anything to worry about https://www.crucial.com/usa/en/memory-performance-speed-latency

If there is a different XMP setting in the bios try that, like XMP 2 or similar. What is your motherboard?

Another alternative is to manually set ram. Disable XMP, select manual, set 3000MHz and enter timings as shown in cpuz > spd.

did you get the images?
Yeah i see it, if it posts and you see it, we can all see it. Thanks.

and there is only one xmp profile, but I think the profile might of said c15 so I don't know why it set at c16.

I would leave it unless you'd like to try your luck manually setting your ram for adventurous or learning reasons. If don't want to bother with it you won't be missing out on anything. See the Crucial link explaining memory timings.

ok thanks, so do you or do you not think the ram has issues cause of this? or is it not a problem with the ram?

one more thing, I remember where you set the timings in the bios, it seemed to have more timing settings than what cpu-z showed.
