I change the system to the servers2016, and try3.4ghz in r20 take 8000, but I get 30000 in CPUz, it's strange, I think 30000 score is normal situation for this CPU. could test what epyc 7551 score in cpuz thxTry to at least run with 1 dimm per die and for your gpu you need to update the Bios, unfortunately the latest bios aren't stable for what I experienced.
If you disable cpu core boost performance with the latest bios you won't be able to post.
That what i get with 2 7551 ES clocked at 3.4ghz and 1 dimm per ccxI change the system to the servers2016, and try3.4ghz in r20 take 8000, but I get 30000 in CPUz, it's strange, I think 30000 score is normal situation for this CPU. could test what epyc 7551 score in cpuz thx
sorry the picture is low quality i cant read it. So i need more dimm for my motherboard which can get same score? i am thinking to buy more 32GB ECC RAM for 4 dimm per socket
I edited my previous post so you should be able to check the picture in full ressorry the picture is low quality i cant read it. So i need more dimm for my motherboard which can get same score? i am thinking to buy more 32GB ECC RAM for 4 dimm per socket
thx ！ it's very useful for meI edited my previous post so you should be able to check the picture in full res
Yes you should at least 4 dimm per socket
Here is some bench with mixed workload on a 16 core epyc ,on a 32 obe it will be even worst
It's a Zen1 architecture with complicated NUMA topology, and with no workstation-class motherboards available. Not ideal for general-purpose workstations, regardless of clock speedI've seen alot of good benchmarks on here of overclock performance however havnt seen any for single core performance. Im looking for a workstation CPU with good clock speed, but would also like RDIMMs. so what kind of single core performance an an AMD epyc give
It's weird that this new bios even works with the ES.THX,when I got the h11dsi, it was bios2.0( produced 2019/9/17), so I need to downgrade my BIOS? or enable some option in BIOS?
So about multiple CPUs configuration you just need to start AsusZenstates as usual,click on apply in order to apply your custom pstates settings to CPU0.
-Once is done go in task manager,find AsusZsSrv.exe (not AsusZenStates.exe) then click on define affinity.
-After you'll change Group 0 to group 1,check "use all core" and click Ok.
-Now you're able to modify the CPU1 pstates by clicking on apply in AsusZenstates app.
In order to revert to CPU0 just change group 0 and don't forget to check "use all core" in define affinity .
Each time you reboot the computer you'll need to apply this process.
If you get an "access denied" error when you want to change the cpu affinity just kill the process and restart it .
I also contacted supermicro in order to ask for a custom bios but they didn't approve my request unless you pay at least 500 motherboard/BIOS...
I hope everything is clear for you
thx , i find the reason which is each CPU need 4 dimm.It's weird that this new bios even works with the ES.
Also i just remembered there was a problem with zenstates and dual CPU systems, did you check if the clock applies to both CPUs?
This is the procedure you have to follow, if the clock is only applying to 1 CPU
other problem is the vrm, I use the dual 40*40*10mm fan to cooling vrm, but it still will over 100°c firstname.lastname@example.org . it happens when I render with c4d or stress tests fpu. now I adjust the CPU email@example.com. The highest temperature 90°c ( vrm). could you share how do you cooling the vrm?
You have to DIY something, i don't think aftermarket VRM Heatsinks for these boards exist.2 threads, some deburring+cleaning and it's ready for a test run.
(no I'm not trying to cool the chokes, it was just easier to mill it like that)
I've got the H11DSi (not the NT), so not exactly a different board.Update on the Bios Mod:
After bricking MrCakes system multiple times i managed to unlock the complete AMD CBS Menu on a Supermicro H11DSi-NT.
Bad News, not everything seems to work... The Custom Core P-States don't seem to do anything for example. Memory OC seems to work a bit.
Are there any willing testsubjects here with different mainboards? (The recovery was always possible via IPMI for MrCake)
But you're using retail CPUs and a newer Bios version than 1.0c, right?I've got the H11DSi (not the NT), so not exactly a different board.
This sounds pretty amazing, any chance you could do a write-up of the process, so dummies like me can follow it?
