Memory compatibility for TR1950X and ROG Zenith Extreme?

Hi all,

CPU: Threadripper 1950X (the OG)
Mobo: ROG Zenith Extreme X399 (original launch).

I’m looking to increase my RAM on my main dev box (for Rust programming), and rust-analyzer would like some extra RAM for sure.

I’m considering this kit: https://amzn.to/3KH2Chl
Corsair Dominator Platinum RGB 64GB (4x16GB) DDR4 3600 (PC4-28800) C16 1.35V Desktop Memory - Black
CMT64GX4M4K3600C16

$736 for the bundle, thoughts?

Is it worth it? I’m currently running an old set of 32GB Dominator Plats, closer to DRR4 3000 (if not lower).

I checked the QVL lists from 2018 on the Asus site and this is not listed.

Thanks M.

You will in all likelihood not be able to run them at 3600 so I’d suggest getting a 3200 or maybe even a little less as the first Ryzen memory controllers and infinity fabrik could only very rarely go over 3200.

Aha thanks! Yes I recall that it was quite hard to push the infinity fabric back then.

What about upgrading the TR CPU? Did Asus release a newer version of their TR boards for the current generation of Threadripper? Are TRX40 the latest boards?

Yes there is the ASUS Zenith Extreme II (Alpha) and Strix on TRX40 with the 3960X(24C), 3970X(32C) and 3990X(64).
The older ones don’t work on the newer boards though, so there is only the choice I listed above.
But those can often push 3600 memory.

The Extreme II Alpha is listed as discontinued. Might as well wait for the new Threadripper pro release?

Check this board https://amzn.to/38NxVcp

If money is not a limiting factor then sure, wait for the 5xxx Threadripper Pro CPUs.

If you’re pushing for more RAM, the clocks will need to be tempered back a fair bit
Do check memory mfrs, for they may have their own compatibility checklist

Think I’m going to hold off. I remember how hard it was to get this CPU to play nicely. I still have some terrible issues with USB hubs on the TR system.

On my Intel systems - no issues. I most likely need to do another AGESA update but given that it’s running I don’t want to risk poking the bear.

Are these new 5xxx Pro CPUs compatible with these existing boards?

ASUS Pro WS WRX80E-SAGE SE WIFI AMD Threadripper Pro EATX workstation motherboard (PCIe 4.0, ASMB9-iKVM, 2x10Gb LAN, 7xPCIe 4.0 X16 slots, 3xM.2,2xU.2 ports, 11 USB 3.2 Gen 2 ports,8-channel DDR4 ECC)

Outside of a BIOS update, I wouldn’t see a technical reason to it NOT working
… It wouldn’t sit well to ignore, considering some active hostility, with TRX4 being 1Gen

Oh, the ASUS Pro WS WRX80E-SAGE SE WIFI is a socket sWRX though?

There will be exactly 1 specific USB port problem free on TR

And it will not be documented, it could be on the back or it could even be one of the front panel ports, and it’s different for every PCB design, but it is there
Some off hand knowledge Wendell dropped on me

As already established, you probably wouldn’t be able run them at 3600
3200 is about the cap and even if it’s running 3200, you’re getting silent error bogging up your memory controller because fabric is too fast
3000 with some really tight timings would be better suited

I just sold my old Asrock X399 Professional Gaming mobo to a teammate who replaced my G.Skill 3200CL14 4 X 8GB sticks that I had running at 3466CL14 stably with new Corsair Vengeance 3600CL18 4X 8GB sticks and a new 2970WX cpu and it is running stable at XMP values.

I could run this kit at 3000 and try to hit 16-16-16-36 or better? It’s rated at

15-15-15-36 / @ 2133MT/s

https://www.corsair.com/ww/en/Categories/Products/Memory/DOMINATOR-PLATINUM-RGB/p/CMT64GX4M4E3200C16#tab-tech-specs

Can grab it on Amazon for $385 https://amzn.to/3uN8L6d which isn’t too bad.

Thoughts?

I don’t see why not. XMP values at CL16 are very tame.
I was running my CL14 3200Mhz memory at 14-15-14-28 @1.4V@3466Mhz

Wow.

I couldn’t post 3200MT/s even at 1.48V, CL16/20/20/38.

Managed to get 3066MT/s at 16/18/18/[email protected]
