I have noticed that my memory write speed is much lower than my read and copy. At first, I thought perhaps my memory was defective. I was using the following kit:

When overclocked to 3800MHz and at CL16 17-16-36 1T and tighter secondaries than XMP, I'm getting the following benchmark results (see attached image). I tried one of my older Corsair 3200MHz kits and that kit was also hitting 76-78K MB/s write with the same secondaries and teriaries, but at 3200MHz. It's as if there is some odd threshold on my memory write speed. Everything else scales up correctly with an overclock, but my write speeds eventually get stuck in the same place. I'll note that much weaker CPUs on this platform with slower memory are able to break 90K, with similar overclocks to my 3800 profile breaking 100K without issue.
Aside from trying different kits, I've also used different BIOS and I performed a clean install of Windows. The issue persists. Any ideas as to what could be causing this poor memory write performance?
