These look super interesting, BUT:

- I can find no mention of them on the SM site, or anywhere in fact
- The heatsinks look like Intel heatsinks... Not even sure if they're big enough to cover a G34 CPU.

They have SGI/Rackable stickers, so likely custom OEM solution by SM?

I thougt these where LGA1366 at first but Supermicro makes a Motherboard that seems do use intel Heatsinks on the G34 socket.

Yup, was just looking into it. That does look like the board, and this looks like the system: Super Micro Computer, Inc. - Products | A+ Servers | 2U | 2022TG-HLIBQRF

You can also see in the seller images how the socket almost meets the edge of the heatsink on one end, so it definitely looks G34 sized.

I wonder how much the FLOPS limitiation impacts performance; I guess these were designed to be used for network pushing packets around at high-speed, where it probably doesn't make too much difference.

I don't need a loud, power-hungry, relatively-low-performance cluster, but I am mighty tempted...

Wonder if you could swap out the CPU for a 6272 or a 6276, both fairly common and cheap (£20-30 per CPU) although they are getting a bit rare it seems for the cheap ones

Hello,
a day before weekend my 2 SuperMicro servers arrived, but now I have time to publish some pics.

out2smal2.jpg outt.jpg out3smal.jpgout4smal.jpg out5smal.jpg
the motherbord is found on SM site it is: H8DGT-HLIBQF-SG007
BIOS was 3.5 upgraded to 3.5c
IPMI FW was 2.1x upgraded to 3.15 .
Select in BIOS for all working nodes (currently 2) Energy saving and FAN is not noisy (but they become noisy if 80% of cpus are busy), two nodes mining monero (soft. xmr-stak-cpu ) 77-82 dB .

Great, mine is still on its way.
So, what is your actual hashrate per node? As far as I see it's ok with a non-ECC memory?

Thank you, linuxmanbg!
These turbo steps looks exactly like the 6276, the core configuration too. Maybe the 6275 has a lower TDP than the 6276's 115 W, but I don't know how to get this value within Linux. Can someone help?
