Doesn't hit the speed it should. CPU: Ryzen 5 1600 Memory: G.

I hope you guys got some things for me I can try. Anything is welcome and much appreciated. Keep in mind that I am a noob at this, so I could easily have forgotten setting something up in the bios.  Did I forget to download possible drivers? Thanks in advance!

You must test both of your DIMMs as described in the post above to be sure that one of the DIMMs is not bad.

Also, triple check that both DIMMs are fully seated in the DIMM slots. Look at the top edge of the DIMM slot and compare it with the side of the DIMM, to make sure the DIMM is fully seated at both ends of the slot. Your memory should be in the A2 and B2 slots.

Do you only get half of the memory recognized at any speed the memory is set to? Such as, the stock speed of 2400?

When you say the memory does not reach the speed it "should", do you mean 3200? You use the XMP profile to set the speed to 3200?

Ryzen's main issues are memory compatibility and memory over clocking. Any memory speed above 2667 is a memory OC and not guaranteed. Reaching 3200 with Ryzen is doing very well. I use the same model of memory with an X370 board and 1700X CPU, and I cannot get my memory above 2933 with stability. Just because the memory we use has a rated OC speed of 3200, etc, does not mean it is guaranteed to run at that speed. Manual adjustment of several options is needed to even try to reach higher memory over clocks.

At this point, you need to determine if both of your DIMMs are working correctly, and then you can try to OC it above 2667.

The board being up to date as you said, means you have the 3.00 UEFI/BIOS version installed?

While you must install the AMD All in One Chipset drivers, they do not help with memory. The latest version of the chipset drivers can be downloaded here:

Thanks for the reply :)

Did the test with my 2 RAM memory sticks over the A2 and B2 port. With the first stick both ports were working just fine (Windows booting up and giving me access to the 8GB of memory). The second stick didn't want to boot up at all. Will contact the store about this.
