SPEC2017 Multi-Threaded Results
Note: We are currently running SPEC2017 on the AMD Ryzen Threadripper 7980X, and we will update this page with our results as soon as we have them. As such, this page serves as a placeholder.
Single-threaded performance is only one element regarding performance on a multi-core processor, and it's time to look at multi-threaded performance in SPEC2017.

Bit disappointing that the memory controller only supports DDR5-5200, considering that JEDEC compliant DDR5-6400 RDIMMs are available.Ryan Smith - Monday, November 20, 2023 - link
At the end of the day it's the same I/O die as Genoa. So it comes with roughly the same restrictions.TEAMSWITCHER - Monday, November 20, 2023 - link
Not surprised by this at all. My 3960X Threadripper system was never able to run 64gb (16gb x 4) at even the promised DDR4-3200 speed. I tried three different RAM kits and even a different CPU (replaced by AMD) and the problem never went away. In the end I believe it to be motherboard issue, it was simply incapable of running stable with any RAM faster than DDR-3000.After spending so much on the ASUS Zenith II Extreme Alpha motherboard, 64GB of DDR-3600 RAM, and a $1400 CPU, the end result was very disappointing. Support from ASUS, AMD, and G-Skill was a long process, and eventually I had to just accept what was working and move on.
Ultimately, I don't believe that AMD and ASUS can properly deliver and support any HEDT platform that is worth the money they ask for it. I sincerely wish Intel would return to this segment, as I never had a problem with my X99 Deluxe II motherboard.

Intel is definitely in HEDT with their xeon w-2400 chipsStormyParis - Monday, November 20, 2023 - link
I've blacklisted Asus. Lots of issues with both specs, reliability, and service.vfridman - Monday, November 20, 2023 - link
I have two systems with 3990X and two systems with 3970X, ASUS Zenith II Extreme Alpha motherboard and 256GB of 3600 speed G.Skill RAM in each system. All runs perfectly and completely stable, even with maxed out PBO overclock. I regularly run compilation jobs that require almost entire 256GB of RAM and never experienced any problems. I suspect you got unlucky with your CPU memory controller.Mikewind Dale - Tuesday, November 21, 2023 - link
I have a ThreadRipper Pro 3950X on a Supermicro WRX80 motherboard. I run 8x64 (512) GB of Supermicro-branded DDR4 3200 ECC RDIMM without a problem.Adam7288 - Wednesday, November 22, 2023 - link
Same exact config! Ram Bros.tygrus - Saturday, January 6, 2024 - link
How are you going with those >200GB matrices & statistics?Many years ago I had to use raw frequency stats, then a program to generate blocks of SAS code that could analyse cross-tab by cluster (weighted) with smaller subsets of interest from every possible combination (multi-morbidity data). Making sure the stats methods still gave correct results. Divide & conquer to fit in limited RAM of circa 2013 computers. In those days it was mostly constrained by single thread & disk/network IO speed (~100MB/s).

Ya know.. I have yet to build an AMD system that didn't suffer from some kind of issue. I don't think I'm unlucky either. I need to stop buying AMD gear thinking... "this time will be different." Because it never is.
