    Any new Supermicro motherboard on the pipe for EPYC Rome?

    As the title says, does anyone have any info about the new Supermicro motherboards for Rome; pretty disappointed with them launching only servers/storage and such... and no H12 MB? Or at least a revision for the excellent and very well priced H11SSL-NC? I wouldn't jump into the Gigabyte and...

    Sun Ultra24 Chassis Front Fan Mount

    I've recently completed a similar EPYC build to the one completed by Patrick. This was an upgrade to my Sun Ultra24 workstation, which I have used since 2009.

    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...

    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?
