Specs: X470 Tiachi Ultimate 3900X Patriot Viper 2x8 gig C19 Here's what I got now. This is bootable to OS and benchable. Load temp on CB20 is 75c on air.  Vcore is 1.35v SOC is 1.2v Vdimm is 1.45v I'll take suggestions how to make this better......other than cooling method. That one is obvious. |

Need better info on the memory, what's the part number.

The 1:1:1 is FCLK, UCLK, and MCLK for reference. Fabric(HT), Uncore(NB), and Memory.

I can already tell you the board, while good is not that great for OC'ing RAM using mine as an example since it's the same board.
My x570 MEG ACE clocks my sticks sooooo much better and that's with sticks the Tachi doesn't like clocking up much beyond 3200, it can push them with the same chip and identical timings to at least 3600 or better.
For competitive OC'ing the x570 chipset just seems better and that's expected anyway. The x 470 Tachi Ultimate is a good all around board and works great as a daily but it's just not the same as others for being competitive....
Unless you get lucky or perhaps there is a BIOS that would make it better and that's possible. I've never "Worked" with this one and the only BIOS update I ever did was to make it work with the 3000 Ryzen chips and that's it.

Fucking board is killer for memory OC. X570 chipset, not so sure. I heard the Strix-E or F models weren't all that great for memory clocking either however. |

Things are still not 100% clear as to what really works with Ryzen 100% of the time but there are indeed some board models/makes that seem to have a handle on it.
x570 I'd expect to do better since it's a later chipset and the boards I'd think would follow suit, at least to a point.
I do know one thing, my ACE is capable of running my RAM up high and may get around to finally figuring out Ryzen with it before long.

Nice! So baby steps, see where the 1:1 tops out. Manually set the fabric to the corresponding memory frequency. Then it wont unlink on auto. Look for power down mode and disable it. Same for gear down mode if you need odd cas latency. 14-14-14 is good, leave it for now. My 4267 set typically does this at 4000mhz 1.60v soc 1.250v. SOC is the memory controller. I recommend using your chiller at some point. Might help the mem clocks keeping cool. The SenseMi high temp alert is 70c cpu core. So if that rig was all auto, the cpu fan is 100%. Its something I just want to make you aware of. So the colder you get this bitch, the lower the v-core needed. These chips respond amazingly well to that. |

easy way to see if your Memory is running 1:1:1 in windows is with either HWInfo (my go-to) or Ryzen Master

Ryzen Master is good for raising the PPT EDC and TDC limits on the fly if you forgot to in the bios XD.

I have Asrock's in OS tool for that. Got it from Splave.
Powerdown is Eco mode on this board. It is disabled. Geardown is on auto still.

Question: What is better in a benching scenario, speed or timings? Obviously something like SPI would prefer tighter timings but at what cost to speed?

Indeed, MHz matters most. Timings do help but not as much as you would think. You would also think C16 would be loosey goosey compared to C14.. but its not really.. I have tried running C15 a couple of times.. my system isn't into too much. And if you had a another set for dual rank, you would still see some improvements here and there.. I'm probably going to go back to 4x8 later this evening and play around a little.

I see. I do have another set but they're not the same manufacturer. They are 3600 Trident Z's.
Speed first eh, I had 42xx @ C16 running earlier I think. I will try that again.

I don't have too much experience running higher speeds like that, I figured I would just stick to 1:1 and let my ram top out at 1900 and run things as tight as I can. Running in Dual Rank isn't that big of a deal, its just a little free performance. It probably wont take you long to figure out what she can and cant do.

Bones was correct. Board is no ram champ. Best I can do stable right now is 3733 @ 14-14-14-28 1T @ 1:1 Gonna play around with the ram more. Learning curve is steep. I even tried just the XMP on both sets of ram. Not a shot.  |

I even tried just the XMP on both sets of ram. Not a shot. Increase the memory voltage. It'll go faster. If I can bench my 2700X at 3933mhz, you should have no issues here. You have to train up to XMP frequency. Setting up XMP on it probably never post right up even on a top Asus board. You fight that memory controller. |

I would consider you lucky yes. I can't even get my Intel rig to post XMP profile of 4267mhz 1.4v 19's because some timings on auto are put to some random number by the board. I have to manually set up the configuration first, hit the retry button once, then it'll post up. |

I was playing around with 2 sticks yesterday, just messin around.. I wouldn't call this stable, I have things a bit too tight for that. I really like this board for the most part. I wish the lan would be ready to go once the desktop is loaded like every other board out there, and not take 38s to initialize after desktop is loaded or wake from sleep. Gets old pretty quick lol..  View Attachment![]() ![]() Man you can crank up some shit! Wish you where on our benching team man. You fit in well here. |

Not gonna work Shrimpy - It's the board itself holding him back so whatever CPU you've got won't make much if any difference. I could clock things up with my x2700 in the ACE but in this board it bombs just beyond 3333 or so. All I can suggest for now is to ask what BIOS you'd neeed to maximize RAM speeds from it, flash it in and go with it. |

Some remarks, if I may Jon, 1.60Vsoc. Do you intend to kill that cpu ? Max on ambient is 1.25v Max on LN2 is 1.45V Scot, I have not shimmed in because the board does not leave much to really tweak and make a difference. Neither your cooling. I would try to have a stable 16-16-16-36-1T. Secondary timings on this board is only by trial and error and any amateur suggestions better be ignored. If it can run FCLK 1800 with 1.20V, then go for 1:1:1. And call it the day. No real reasons to torture the cpu on this board. |

Had my 2700x at 1.4v SOC.... still alive and used daily. CPU v-core during sub ambient testing and sub zero testing up to 1.6v. But I did not mean SOC 1.6v for Scotty. Maybe a misprint. |
