Poor memory (Kingston HyperX 3000 C15 2x16GB) performance, wonder why.

Hi Guys,

From this link you can check my system and also my test results: http://www.userbenchmark.com/UserRun/5776015. Unfortunately those results on the memory are confirmed by other tools I run like PassMark Performance Test 9.0 where it scores 2024 points with model average 3033 I just don't know where to start looking. I've chosen the XMP profile 2 for this memory kit and it's supposed to be running around 3000 MHz or so but that's the only thing I've touched in BIOS. Also I've set the max speed of the CPU to be 4000 MHz on all cores in AMD Ryzen Master. Any suggestions? It's a new PC for me and I was not shy of experimenting with overclocking but last time I did that was 10 years ago on my Core2 Duo and that is the system I replaced with this new one. I'm not after world records I just want all of the components to perform per their default parameters or at least within average for their model.

Perhaps it's running in single channel mode due to putting the memory sticks in the wrong slots? Look in your motherboard manual for guidance as to which slots you should populate first. You probably should have got four memory sticks in the first place because the x399 platform has quad channel memory support.

Can anyone with Threadripper say anything on this subject? I'm running memory in NUMA which means both controllers are working. Not sure whether that means both work in single channel with 1 of the dimms or both work in dual channel with both of the dimms, someone please confirm.

Don't you need 4 memory sticks for Threadripper? It's quad channel?

No. You can even go with one only. It is quad channel by was of core dies, it has two of them and each has two channels.
