Memory latency issue

[handofgod1981]

Running AMD thhreadripper 1950

having memory speed issue, system doesn’t perform to full potential 

running ROG zenith extreme motherboard 

g-skill RGB 3200mhz 2x8Gb 

only clocks at 1600mhz

adjusted speed in bios, didn’t help

what else could I try?????

1600 MHz is the correct clock for 3200 rated ram. 3200 rating isn't technically "MHz" but number of transfers per clock.

^^^ Mine says about 1596 from CPU-Z, but it's Double Data Rate so you double that and it's the full speed, or something like that.

Threadripper uses quad channel memory.

 

But if it's just the clock speed showing 1600mhz then as others have mentioned it's because DDR means Double Data Rate. So 1600mhz=3200mhz.

Try checking what it says in cpu-z or hwinfo64.

Good spot. Using 2 sticks will reduce the available bandwidth by half compared to going quad channel.

userbenchmark.com stats that my memory setup isn't performing to its full potential 

not sure if its correct??https://www.userbenchmark.com/UserRun/12505555

Running two sticks not 4 of ram will mean your peak bandwidth will be half that of other systems. To check, you can run CPU-Z, screenshot and post the memory and if possible SPD results (with module selected) here?
