" rel="nofollow - mobo: ASROCK x370 Killer SLI CPU: 1600 RAM: Corsair Vengeance LPX ( CMK16GX4M2B3000C15 ) My CAS timing is settings its self to 16 regardless of XMP profile and manually setting it to 15. I notice this in BIOS as well as all software reads my CAS as 16 not 15. Bug? Not cool : /

Drain_Bamaged, there is a BIOS setting -Advanced Boot Training- that is "training" the memory. It may be the cause of this. I suggest you disable this and see if it helps. The results may be memory errors.

Thank you Hope it gets fixed but it's been a few months so....I guess products working properly isn't a high priority.

Intel struggled with the same issues when they moved to DDR4. I do believe AMD should have spent more time on this before launch though. |

| I also had the same problem when I would set the cas to 15..not matter what speed I chose and disabled boot training it still defaulted to 16 when I exited the bios. |

| Then maybe Corsair shouldn't be selling C15 RAM calling it Ryzen ready. Not only that but my RAM is on AMDs list of compatible RAM. A lot of folks screwing up on this. |

my ram is gskill cl 15 yet it still selects itself to run 16/15/15/15 timings i try not to lose sleep over it  compared to an older asus setup i have here im just glad it runs its proper max ram speed and close-ish timings the other system wont run 1866 HYPERX ddr3, even at 1333 with recommended timings (i have to loosen timings just to get 1333) ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

If I recall correctly it's a Ryzen thing. Not the end of the world really, but I see your point. Someone suggested disabling memory training, I haven't tried that yet, but with memory training off, the system posts much quicker. |
