— 4100 MHz (BCLK 102.7) just for getting 4415 MHz on CPU for fun. Timings: 18-23-23-28 cr1 - and memory is stable i tested it with memtest5 v0.12. But it works in that way only with custom "turn around timings". Without it, I can get only 3600 MHz stable and 3733 MHz booted but not stable. And of course memory chips, it's 8 Gb C-die (Alius / 18 nm) / 1 die. JEDEC DIMM Label: 8GB 1Rx8 PC4-2400T-UA2-11. Part Number H5AN8G8NCJR-UHC. P.S. (i7-8700, ASRock z390 extreme4).
