I have the following configuration:
Motherboard: Supermicro H11DSi - AMD SP3 socket - DDR4 RAM - Extended ATX CPU: 2 x AMD EPYC 7351 - 2.4 GHz - 16-core - 32 threads - 64 MB cache - Socket SP3 Cooler 2 x Noctua NH-U9 TR4-SP3 - (for: TR4, SP3) - 92 mm 16 x Memory: RDIMM Crucial 8GB CT8G4RFD8266 (Specs: DDR4 PC4-21300 • CL=19 • Dual Ranked • x8 based • Registered • ECC • DDR4-2666 • 1.2V) SSD: Samsung V-NAND SSD 970 PRO M.2 - 512 Gb OS: Windows 10 Pro x64 MB: Last Firmware on BIOS and IPMI. When I run the calculation on Ansys CFX on 30 - 32 cores, with all memory, after 2 or 5 min, I get a blue screen (DPC WATCHDOG VIOLATION) If I leave 8 slots memory 64GB, system works is good and stable. I tried different OS and swap memory. Any ideas? The problem is very similar to this: https://community.amd.com/thread/224665 Thank You. Last edited by Rec; January 21, 2019 at 09:42. Reason: swap memory |

This is a configuration very close to what I was thinking about building. The memory you are using is the easiest accessible here and what I had planed to buy. The SSD used is with NVMe interface? The board only supports a PCI Express 3.0 X 2 but yours are 3.0 x 4. A reseller of Epyc workstations only offer SSD with SATA3 og SAS3 interfaces (deltacomputer.com). Perhaps they have bad experience with NVMe. I cannot explain why it works with 8 DIMMS. I hope You find a solution and post it here. Good luck.
NB: On supermicro's web page Window 10 pro is not listed as supported for the motherboard! Have you tried with a newer Ubuntu or Fedora distribution? Last edited by ErikAdr; January 22, 2019 at 04:39. Reason: Windows 10 pro not supported |

Hello!
No, I only use SSD on M.2 slot + 2 SATA 8TB RAID. NVMe very expensive in my country. Yes, i try Centos 7.6 and Ubuntu 18.04. Quote:

FYI, the Samsung 970 Pro is an NVMe SSD
