dynatron makes a few: https://www.dynatron.co/air-cooler?AMD+CPU+Socket=SP5

I understand the confusion as with AI, everything seems to be "super" :) These are the next gen of connectx-7, not the Bluefield series of DPUs. These nics are referred to as the 8180 vs the 8240 version. The exact part # is shown in the last picture of the ebay seller that was selling the...

So then I guess I can put you down for 2:)

I have 2 brand new in box. These are the new 800G single port nics. They can be 800G for IB or 2 x 400GE for Ethernet. I attached pictures of my cx8 nics (with the 3 cx8 nics) and another seller that had the same nics but sold them in the last photo. They can also be configured to be 8 x...

I was updating one of my cx7 nics from psid 856 to psid 1244 today and noticed something important. I needed to jump the FNP pins to put into flash recovery mode. I was then able to cross-flash and upgrade to the latest version of fw. After the flashing was finished, I shut the server down and...

you can see my other post in the networking thread for the real answer. It is for a traffic generator application. Trying to optimize a hw config for generating the most amount of traffic including tls type traffic.

Finally started getting my cx8s for my next beast build. It was a little bit of a puzzle trying to find 8 extra MCIO x8 connectors on the mb. You need a pair of the MCIO x8 connectors to connect to a proprietary MCIO x16 (like but not the same!) connector on the back of the cx8. My plan is to...

and why not add a few cx8 nics to the party! I just need to rearrange the mcio x8 connectors on the mb to connect to the back of the cx8s

just got a new toy. supermicro sys-222ha-tn with 2 intel 6979P 120c cpus. These cpus use the massive LGA7529 socket. for context, the smaller of the 2 below is a normally large Intel SPR:

there is another thread that I gave some detail on how to use the mtusb-1: https://forums.servethehome.com/index.php?threads/mellanox-connectx-4-or-newer-bluefield-tips-tricks.47779/

all of the pci 4.0 hpe nics that I have found seem to be cx6 not cx5. I have not had any luck cross flashing between the 2 generations.

yes, EDAT means vpi and pci 4.0 but that is for mellanox fw. We need the hpe fw and I could only find the following: Firmware for HPE InfiniBand EDR/Ethernet 100Gb 2-port 841QSFP28 Adapter : HPE part number 872726-B21 That nic is pci gen 3: LnkCap: Port #0, Speed 8GT/s, Width x16, ASPM not...

Which specific sku is the cx5 dual port 100g that is PCI gen4? I need to find the .bin file for that model and it needs to be signed.

do you know which hpe cx5 signed fw supports pci gen4? I agree that you can probably cross flash signed fw with signed fw but I couldn't find any hpe cx5 signed fw that would support pci gen4. I think the went to the cx6 nics for pci gen4 support. that fw might be 32K and might not work with...
