Yea sorry for all the result posts, got my 13600KF with a golden IMC and MSI Z790, is this the highest clock : CL for 2x16 DDR4?

Unfortunately though something is seriously wrong with the new board when running in Gear 2, on my Asrock Z690, 4800CL17 G2 gives 75k bandwidth / 52ns latency, on this new board, the same settings only give 61k / 67ns.

At 5333-5400 the bandwidth DROPS to 43K when it should be over 85k!!!

Will be bothering MSI support a lot soon when I can be bothered to raise a ticket, I really wanted to use this setup to do some extensive G1 vs G2 benchmarking and can't now.
