Just got this combo, overall works fine except for one thing. Refuses to work with 4 dimms at more than 3000MHz, which is a bummer cause that's what I had. On 2 dimms all good they work at 3600 cl16 gear 1, same timings as my old z390 in fact with even better transfer rates. I don't want to send it back just for this so I suppose I'll sell the 4 memory sticks and get a 2x16GB. CPU OC nothing fancy, 5.4GHz all core and 1.290v about 190W in cinebench and 90C on a 39e slim cooler. In games sits at 55-60C and max 75W. Gain from 9900k @ 4.9Ghz? 0 .. plain feckin 0 lol, same fps in forza 5 using 4k. Granted on cpu render/sim the 13600kf is much faster but since 9900k was able to render about 160+ then there is no gain if I'm capped at 140 @ 4k. I suppose I was just bored and wanted to try a new platform, with minimum upgrade. I also got all of them on a deal, mobo for 199e, cpu for 320e, cooler for 39e.
