" rel="nofollow - I have the asrock x370 taichi and also have the Trident Z RGB RAM cl16 (F4-3200C16D-16GTZR). Are these two compatible with each other at the max 3200mhz frequency? If not what is the lowest frequency i can get it to for it to boot stable? Link to the ram i have: https://www.newegg.com/Product/Product.aspx?Item=N82E16820232476&cm_re=trident_z_rgb-_-20-232-476-_-Product ------------- New Builder |

Compatible, yes. 3200, meh, don't get your hopes up. They're Hynix A-die. The good thing is they are Single Rank, Single Sided. I would try the 1.0.0.6 BIOS first as Hynix seem(s)(ed) to prefer that BIOS rev. over 1.0.0.6a BIOSes.  |

if you can afford the extra cash the cl15 and cl14 sticks should have the samsung B dies ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

What, a TridentZ memory model with Hynix memory chips? Not Samsung B-die? Of course, G.SKILL does only include Intel systems in the QVL: http://www.gskill.com/en/product/f4-3200c16d-16gtzr" rel="nofollow - http://www.gskill.com/en/product/f4-3200c16d-16gtzr What's the lowest frequency/speed you can get it to boot stable? We can see that is 2133. I assume you mean what is the highest frequency you can get it to boot stable, if not at 3200? Usually that is 2933 for Samsung B-die chip memory, if not more. 2667 is the Ryzen max specification. Which CPU are you using? We'll need to see how your model cooperates. It's very difficult to predict memory speed potential with Ryzen, if the memory does not use Samsung B-die chips. You'll just need to experiment with memory speeds and timings and see what happens. The XMP profile is no doubt designed for Intel systems so some manual memory tweaking will be necessary for higher speeds. The SOC voltage set to ~1.1V from the default 0.900V, for example. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Most high speed CL16 sticks seem to be Hynix A, B, or M die |

when i was looking it seems samsung dies were 3200 and above and at 3200 needed to be cl15 or cl14,,,,,3400+ etc was using b dies (that applies to the 8gb sticks) ------------- [url=https://valid.x86.fr/jpg250] [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

Good point. I forgot to mention that in my reply to parsec. |

Now if only DDR4 pricing would come down. |

BTW, just saw that this new memory is Threadripper/X399 only and only 4 channel.

Yes, I did the mistake with GSkill's TridentZ 3200 C16. Now, after reading and reading and reding on forums, I can be sure all Gskill or Corsair 3200 C16 are Hynix. To get the so much beloved B-dies, you have to look at 3200 C14, 3466 C15 or 3600 C16 as a minimum, and beg manufacturers don't change to Hynix or Micron again at those speeds :-( Anyway, with current Agesa 1.0.0.6a UEFI, I can get the TridentZ 3200C16 2x8 sticks Hynix MFR at 2933 14-15-15 stable at 1.375v to avoid cold boot loops, so it's worth to test it at that speed on the OP's Taichi.

I read recently that it will continue to go up!
Your Corsair 3600 and (I think...) G.SKILL 4000 memory are not Samsung B-die? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

The memory manufactures really should state the source of the memory chips in their specifications. Instead, we get to discover what they are after we buy them, or when users post ThaiphoonBurner screen shots of their memory. I imagine the manufactures are afraid to include the memory chip manufacture, since enthusiasts would avoid certain types. Remember the Samsung Green DDR3 "magic memory", that worked with any DDR3 memory controller? You could mix unmatched DIMM kits and they would still OC a step or two above their rated speed. Multi-DIMM kits of this memory didn't even have sequential serial numbers, apparently not matched at all. I finally have my 3200 FlareX 2 x 8GB working at 3066 stable in my X370 Killer SLI/ac board. 14 14 14 28 1T, GearDownMode disabled. Just tweaked advanced timings and reduced SOC voltage to 1.1V. So close to 3200 now, but Windows just won't start. No BSOD but also no Desktop. Hey, where is our tREF setting in the UEFI, ASRock? The tRC setting has a mind of its own, "correcting" itself. Be sure to check it after trying a higher memory OC, at least mine will remain higher after a memory OC fails. Also, Restart to UEFI works for me now consistently, even at 3066. I thought a memory OC was breaking it but that seems to not be the case. I have Advance(d) Boot Training disabled... I wonder... ------------- http://valid.x86.fr/48rujh" rel="nofollow">

My 2 kits of F4-4133C19D-16GTZA are Sammy B-die My 2 Kits of CMK16GX4M2B3600C18 are Sammy B-die My 1 remaining Kit of F4-3200C16D-16GTZB is Sammy E-die My other 2 kits are unbranded Hynix 3200MHz edit: added unbranded |

That's a good question. It's there, and it changes by what mem I put in. Guess I'll have to discover what Auto setting it is. G.Skill F4-4133C19D-16GTZA:  |

tREF must be set to something, but we don't have access to it, on either of the two DRAM Configuration screens. That is, we don't have a tREF option in either screen that I can see, or off by itself like GearDownMode. I noticed this while using Ryzen Timing Checker screenshots. We have most of the options shown in that display, but not all of them. ------------- http://valid.x86.fr/48rujh" rel="nofollow">
