I have this board and it is really solid, the only "problem" is that you need to have a dedicated vent blowing over VRMs if you plan to overclock and do stuff like rendering when CPU is at 100% for longer periods of time..
thats the problem it 'shouldnt' there is no reason for it and no XMP profile defines tRC as 48 and sets that to 75 and JEDEC is telling MSI to set tRFC to 560. and its a known bug still never addressed.

" Real-World Impact of Lower Level Memory Timings
Different kits have different JEDEC standards, so different subtimings get loaded. This is an issue we’ve run into before: we had two kits identical in frequency and capacity, but with different latencies; however, the 16-18-18-36 Corsair kit somehow outperformed the 14-14-14-34 G.SKILL kit in tests. After discussing this with both manufacturers, it turned out that Corsair’s sticks were dual-sided with groups of 512MBx8 ICs (memory chips), while G.SKILL’s were single-sided with groups of 1GBx8 ICs.
512MBx8 is an older style, so it actually has tighter subtimings defined by JEDEC (see “What Are Timings?”). The biggest culprit in this case was tRFC, or Refresh Cycle Time. We’ll cover the full definition of this in part 2, but for now the important thing is that the value set by JEDEC for Corsair’s type of kit was 416 and 560 for G.SKILL’s. When we adjusted the G.SKILL kit’s tRFC value down to match Corsair’s with no other adjustments, it pulled ahead in performance and remained stable."
I can set tRC to 48 and keep it on 3200 @ 14-14-14-34 but you cant touch tRFC (which i wish they explained how or what mb because honestly I want to dump this one)
mine runs like a beast... I run 4ghz 24/7 other then that I really dont OC much. I have tested these timings even on stock settings no XMP 1 or 2, no OC at all 2133 up to 2667 and they always setting latency high. now from what I can read anywhere about this this shouldnt be happening at lower/stock/non-OC speeds the latency should be backing off but it dont...
my biggest beef and this is honestly with the whole TR/Ryzen vs Intel thing... is there really memory sticks designed for only intel or amd or is this a total lie? I mean I look up benchmarks @ passmark sorted by cpu and why is it all the lowest latency chipsets are listed as intel only? (to clarify this is on AMD ryzen benchamrks so people got intel ram listed there running on ryzen)or is this false reporting I seen kingstons down around 52 for latency which is like a 50+% cut over what Im at now... I mean Im sorry but the bottom 10% in the world for ram latency is puke level sickening.
If anyone wants to suggest a good motherboard for the x399 that isnt nerfed and locked down like MSI please refer me to a board thanks. more I talk about it the more sick I get over this... Im not even bringing up how msi and their HDA drivers for this board are broken AF also... ask anyone who does dolby digital live encoding
