x399 Taichi + TR 1920x - Dr Debug Code 10 / 16

I had the same problem, knew of this thread, but still thought that I had the RAM seated properly. Turns out, no, I didn't. By chance I got one slot in the correct position. For anybody else, these are the correct and wrong positions:

Well i have find the problem , and it was indeed a memory issue, but it was not a compatibility issue, it is just that ram kit where not enough plug in the memory slot. You have this weird one clip system, so even if you're ram is correctly clip and thing sound ok, you have to push a lot on the left part that doesn't have clipper to be sure that the connection is OK. i have plug and unplug the stick more than 10 times and at each time i made the same mistake. So in case you get this error 10 / 16 don't hesitate to force a little on the left part even if the clip looks ok.

Thanks again for your help guys , the PC looks to work smoothly, i will keep the hyperX because it looks smoother but the corsair LPX 2666 CL16 15Gb which is not in the QVL is compatible also.

Cheers

thanks for extra info xhue, i need lot of ram for CGI rendering and Fluid simulation computation. Good to know for the 2400 and the 8 kits.

More so, AMD claim TR's IMC should work fine @ 2400 for 1st gen. They basically guarantee it.

2400 is also a JEDEC standard rate, so as soon as you get a decent kit you should be safe.

Depending on your upgrade timeframe you may want to check if some kits are not EOL, i.e. you will have future availability on the market.

If OP needs 128GB he most likely needs it for rendering or VM.

Rendering won't benefit from tightened timings since it's mostly bandwidth limited. Maybe investing in a decent kit and OC it later is worth it, as it will save you many run-hours in the long-term, i.e. it will pay off.

VM on other hand will have noticeable performance uplift from tight timings.

I agree with Xhue here, the G.Skill Flair X range are specifically designed with Ryzen in mind (both AM4 and TR4). Using 8 modules will limit your frequency, particularly on first gen as Xhue noted. For reference I am using an X399 Phantom Gaming 6 paired with a Threadripper 2950X and I found the following when testing out different RAM configurations:

1: 2 modules -> 3600mhz
2: 4 modules -> 3200mhz
3: 8 modules -> 2666mhz

The kits were rated at 3600mhz cl19 and the additional 2 kits were on loan from a retail outlet near my home where I purchased my 2 kits. Corsair Vengeance LPX 16gb kits x4. I am afraid I don't recall the model number, I have it written down somewhere but I would recommend Flair X over these anyway. You can expect a first gen TR to perform a little worse than my 2nd gen with 8 modules, I would guess xhue is on point with ~2400.

If your goal is capacity and you know you won't likely get past 2400 anyway you can also check out G.Skill's Fortis RAM, it is also designed for Ryzen but is more budget oriented. I believe it goes all the way up to 3200 but the timings are not as good as the flair X stuff. Running at 2400 with tight timings on cheap kits will probably save you a fair bit without sacrificing any real world performance.
