    Intel IMDT + Optane (DC P4800X) + EPYC

    I wondered if anyone in these forums knows whether Intel software defined memory technology (IMDT + Optane DC P4800X) will work on an EPYC platform, or is it restricted to Xeon. I'm software dev considering building a machine for deep learning + video editing + general experimentation with...

    Dell EPYC R7425 DIMM Operating Speed

    Hi All, Just purchased our laboratory a brand new EPYC server from Dell - A R7425 chassis with dual EPYC 7451. I also purchased 8x32 GB DIMM modules rated at 2666. The BIOS is only recognizing them as 2400. In looking through the manual...

    AMD Epyc - performance impact of runing 4 channel memory instead of 8 Channels

    Hi All I have a client who is buying a 1U single socket Supermicro server with an Epyc 7351P 16 Core processor. The application is as a small Proxmox host, running Debian VM instances for clients. The intention is to run about 40 VM's at 128GB of RAM (32GB modules), but retaining the option...

    Selecting Dual EPYC motherboard... Is there any other option except Supermicro?

    Googled, but no luck... Seems like Supermicro H11DSi-series is the only motherboard for Dual EPYC configuration... The other choice is Gigabyte MZ31-AR0 or Tyan Tomcat SX S8026, but it has only a single EPYC socket... I like my Supermicro H11DSi-NT, but it has no Hard Disk Drive activity LED...

    Looking for a solution with 6 full x16 pcie lanes

    Hi, I am in need for a solution that offers six full x16 pcie lanes. I need 4 slots for 4 GPUs (for deep learning purposes, for certain models and toolboxes I use, GPUs in an x8 slot perform significantly slower than in x16 slots), 1 slot for a 100gigabit Mellanox ConnextX-4 NIC, and 1 slot for...

    Epyc in h265 transcoding

    Hi, I’m looking for a CPU good enough to handle 2-4 simultaneously 1080p h265 transcoding and at least 1 4K. Does an Epyc 7281 work for this job? Is a Xeon e5-2640 v4 better?

    Are there 3rd-party cases for the new Epyc TYAN S8026GM2NRE w/ Oculink?

    Hi, I'm interested in getting a Tyan S8026GM2NRE motherboard but I'd prefer to put it in a 3rd-party case because 2U tends to have too many cooling issues in my environment (would like a big full-atx case to put it in) but it has PCI risers instead of PCI slots Has anyone heard of a 3rd-party...

    Hi All Has anyone here got any tips on where to purchase Epyc motherboards in the UK Currently I can only really see the GIGABYTE MZ31-AR0 available from Insight UK - but I'm not a huge fan of its layout, nowhere seems to be stocking any of the Supermicro H11SSL-* boards, CPUs seem to be easy...

    Finally managed to do some testing with AMD EPYC 7401P on CentOS 7.4 with both default 3.10 Linux Kernel and 4.15 Linux Kernel. But I ran into some cpu soft lockups during UnixBench test and was wondering if anyone else have run into these before Benchmarks - Packet.net bare metal cloud provider...

    AMD EPYC 7351P + GIGABYTE MZ31-AR0 = 7 GPUS?

    Hi Guys, I just saw the review on the AMD EPYC 7351P CPU but it did not really go into GPU usage so I thought I would do a post in here to get some feedback and or advice on this. We are looking to build a 7 GPU rack using the EPCY so we can take advantage of the 128 PCIE lanes, basically...

    AMD Epyc CPU frequency on linux

    AMD Epyc, memory and motherboards

    My plans on trying AMDs new Epyc processors for my new workstation are in their final stage. But a few questions remain. 1) Memory compatibility - frequency Right now I can't really afford buying 16x16GB DDR4-2666 memory. But I have enough 16GB DDR4-2133 reg ECC waiting to be put to use. I know...

    1P AMD EPYC 7601 Power Consumption

    Not great but not bad by any means: 351W Decent idle and maximum views of the system today. That is a fairly bare config with 2x SATA SSDs and only using Broadcom networking. No 24x U.2 NVMe drives or NICs installed.

    This just looks funny

    Realized I needed this screenshot: It certainly looks funny. 8 NUMA nodes, 4 threads per node. Then again, $450 CPUs.

    AMD EPYC 7251 Release Date

    I was originally told that the production date for the EPYC 7251 was going to start on August 31, 2017. At the same time, we had a retail marked AMD EPYC 7251 show up today. The availability should be getting much better on the $500 ish street price 8 core/ 16 thread lowest cost EPYC part.
