Trying to setup direct infiniband between two machines with CX4 cards (EDR). apparently there is no OpenSM for WinOF-2 drivers.
Any ideas how to get this concept to work...
I have a whole bunch of of EPYC Rome ES now, but unfortunately it's an odd number and I want to consolidate on all dual socket boards. So I either need to buy one or sell one.
Selling a 32 Core Rome ES (ZS17) for $800 US or 1000 CAD, free shipping. These are overclockable, and I'd be happy to...
Do I need a motherboard that explicitly supports Xeon W series
(X12SPA-TF) or does any "Xeon scalable" board work?

In general, I really just need pseudo workstation board of any type that can support a Xeon...
I need 128 cores total, and strongly prefer non-QS/ES although off roadmap is OK (7v12, 7B12, etc.)
So looking for 2x64 or 4x32 or well, whatever you got. Prefer North America, but even EU is ok.
Hey everyone, I did a bunch of googling on this and I can't figure it out, and I can't even find the topic in the support documents.
I'm running pfsense + ICX6450 with vlans. I have the pfsense in only 1 subnet and run DHCP on the switch. DHCP works fine but the switch seems to both:
I have 4 x 16GB sticks for DDR4-2400, but hear me out... This stuff overclocks great and doesn't need crazy volts to do it. I run it at 3066 MHz 16-18-18-18 @ standard 1.35 volts on Ryzen AM4. It may very well go higher, I can tell you my Ryzen doesn't :(
It is quality workstation...
I have 4 sticks remaining (started with 16) of 16 GB DDR4-2133 ECC UDIMM. Model KVR21E15D8/16
I have also qualified them all on Ryzen AM4 AX370 Gaming 5 as working stable at 2400 MHz.
I tested this configuration for days...
They are retail from Amazon, so have warranty.
Edit: I caved and bought new sticks. The UDIMMS will be for sale shortly.
I have 256 GB of DDR4-2133 ECC UDIMMs in 16GB sticks. I need either RDIMMs or LRDIMMs.
I did a swap thinking it would work in my server, and oops, my board doesn't support UDIMMS, didn't realize some boards didn't. If...
I have a single stick of Kingston KTH-PL424L/32G.
LRDIMM 32GB 2400 MT/s. Was a mistake order, was tested and then put aside, so basically new.
$350 OBO... Now $250 and still OBO!
Would love to see trades on:

So my cluster uses QDR Infiniband (Mellanox Connectx-2 cards). To date I had bought all 2 m passive twinax cables. These got me consistently 3300+ MB/s and around a 1.2 to 1.3 microsecond latency
latency = 1.3766 microseconds

I'm excited to see that I, a relatively new forum member, have been approved for Round 1 of the Build a Server for Charity event.
I entered based a proposal of a low cost server that I was already planning on building regardless, and for that build I want to stay true to the idea of building a...
First post. I want to start by thanking everyone on this site for all the information they have made available such that I could make this build possible. Skip ahead if you want, heh.
Just 6 months ago I was using a windows file server with no redundancy and drawing over...
