Hi,
I have a 2990WX cpu with CL14/ddr4-3200 memory (4 sticks) running on an MSI X399 Gaming Pro Carbon AC motherboard. I am an AMD newbie. I ran some AMD cpus decades ago.
My primary interest in running this cpu is to get maximum production of Seti@Home cpu tasks under Linux.
I am aware of the direct memory/2 hop memory issue.
I am currently using the MB builtin OverClock feature to run it at 3.7GHz with Cpu boost off (recommended for my app), Precision Overdrive on, XFR off and Quiet&Cool off.
My understanding is I now have the fastest recommended ram hardware and I believe I have it set to use the ram at full speed.
I am wondering if I would get "more production" if I was to drop the OC and go just with the regular Turbo boost features?
A previous test before I got my C14/3200 memory ran at about 3.3GHz.
I am currently running 60 cores out of 64. Other research I have read seems to indicate that 40 cores is about the sweet spot compute intensive production. I am testing to confirm that.
Thank you for your comments and suggestions.
Respectfully,
Tom M
I do not have much to add, tlgalenson. You have a perfect laboratory to get at what you need to know. You did not how much or brand of memory. At 64 GB you should be able to run a little faster (maybe 3600 MHz) than 128 GB and Ryzens and Samsung B-Dies really seem to like each other and results in a more stable system. Here is a really nice free memory utility if you are not aware - Thaiphoon Burner. Let me know if you cannot find it via Google. Posting a link causes a few minutes to a day or so delay in posting due to moderating. Another really great utility is Ryzen Master (AMD), especially for temperatures because it is the only reference I am aware of. Both of these are W10 only. You may want to boot W10 and do some testing. Enjoy, John.
