I had to upgrade the RAM capacity of my system (32GB->64GB), and found this kit (F4-4000C18D-64GTZR) for a cheap price, so I bought it. Plugged it in my system, and other than an early bootloop upon installation, it seems to work fine, no issues with XMP.
Timings are 18-22-22-42-64, which is not too bad. Command Rate and Gear have a strange relation. When I put Gear 1 it switches to Command Rate 2T and vice versa (Gear 2, CR 1T). Anyway Gear 1 wasn't stable with default XMP voltages. TRFC is crazy high at 1023 (my previous kit was 275).
What should I expect with this kit? My previous kit ran much tigher but it was 32GB. I know that for DDR4 4000C18 is already considered high. Is there much room to improve?
