I don't believe procODT is specifically "for" any particular stick of memory.
It has to do with MEM VDDIO and MEM VTT than anything else. Likely also, it probably addresses the differing way a manuf lays out the traces between the mem slots and proc socket To the best of my knowledge, it addresses/alters the processor itself. procODT = Processor On Die Termination |

No go.. Oh well, thanks for the tip. Interestingly I noticed my commamd rate improves to 1T with 2 dimms, but drops to 2T with 4. Fun stuff... |

Try setting your ProcODT to 53.3ohms with all 4 dimms installed, I am using a corsair 3600 kit and that got me up to 3466 stable. I will be pushing for 3600 later today.
At the moment I can't find any info on what ProcODT should be set to for any RAM models. 53.3 has been thrown around here on the forums and worked for me, after serious instability all seems well.

Always always reset the BIOS when adding/removing/swapping mem on an AMD. Intel too. Edited by wardog - 22 Jun 2017 at 10:26am |

Would be awesome if they could add a bios setting to choise between 2x sticks at higher speeds or 4x at lower. So you wouldn't have to physically remove sticks to switch.

Meh, hold on to those two not being used for the moment. Ryzen using 4 sticks does appear to lower the available top end MHz wise. I use "appear' there as there seems to be confusion over the specs when released. See the sticky under AMD here. There's a User here that says his four run higher that published spec. Is that related to maturing AGESA releases? I honestly don't know ........ |

Thought I'd share my experience: Originally purchased CORSAIR Vengeance LED 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Model CMU32GX4M4C3200C16 If I'd done more research ahead of time I would've probably bought a 2x g.skill, but with newegg restocking I just stuck with it. Initially could only get 2667 (boot/stable) with 2.2/2.3 bios, which wasn't bad considering I was running ram that isn't on the QVL and doing 4x dimms. Pulling 2 dimms, still maxed at 2667. So just upgraded to 2.4 with agesa 1.0.0.6 and now I can only get 2133 with 4x config, which is frustrating. But, I pulled 2 dimms again (leaving A2/B2 populated) and voila, 2x runs 3200 smoothly. Since it's probably too much to hope that a 4xdimm config at 3200 will ever be supported through agesa/bios updates (right?), just going to try to sell my other two dimms.

Thanks for the comment Burstaholic. What we are seeing, from all board partners, is classic new platform teething issues. It happens every time we see a completely new architecture. I think the problem stems largely from AMD not having released anything truly new for almost a decade. AMD fans have not been subjected to the teething issues new platforms bring. AMD may have been behind the tech curve but their products were matured and bug free for the most part.
Regardless of AGESA code and teething issues Ryzen is a huge success IMO. I am loving my Ryzen system, bugs and all. I am enjoying tinkering with it and trying to find that magical UEFI setup/version that will allow me to run my RAM at 3600 without stability issues. I am an early adopter junky tho, for me it's half the fun. That said, most users don't have half a dozen PCs up and running at any given time and something like instability ceases to be amusing as a challenge and becomes problematic. I fully understand the frustration. I want users to be aware that there is a lot less to be gained by RAM frequency than most reviews/articles claim. Sure, if you are using a GTX 1080, 144hz monitor and want to trounce intel gaming performance then RAM is where you need to look but for most people on lower tier GPUs it isn't anywhere near as significant. 100fps vs 110fps is not even going to be visible on a 60hz monitor, 5 seconds quicker in X or Y benchmark isn't going to magically make your PC feel snappier. AMD caught flack for Ryzen not matching up to intel in 1080p gaming on high end hardware, RAM speeds in part contributed to this fact. Fans have taken this and really run with it....
