Packing was okay. I don't think it was shipping damage. The CPU seems to have a severe internal short, because when put into an H12SSL board, it completely stops the board. Not even a PWR_OK LED or BMC Heartbeat LED.
It's a great stroke of luck that this faulty processor didn't kill the board in the end.
Well I guess Supermicro has proper OCP implemented, hence the board not showing ANY signs of life.
This should NOT happen according to Supermicro support (a faulty CPU completely disabling a board, including BMC)
I first RMAd the board, thinking the board was somehow dead (because I didn't even remotely consider that a faulty CPU could disable the BMC), but obviously board came back with "no symptoms found". Board runs other CPUs just fine...
Usually stuff is not designed for all the potential 'what ifs' so I'm sure that shorted cpu was just doing something completely unexpected. But luckily supermicro's design was robust enough that even though the bmc was shut down, the board wasn't damaged at all. What suprises me is that such an obviously faulty cpu was sold in the first place. Were they not tested by the seller before they sold them?
Added WTB Up to 24x of MPO / MTP-12 to 6x LC fanout / breakouts - either a Male (Pinned) cable or a Male (Pinned) cassette - Please no 4x LC breakouts, I want to use all 12 fibers.
SN2700 1x reserved, pending payment
Added WTB: 2x LGA3647 1U Barebones: 1U, 2 x16 Slots (ideally full height), single socket, must support high-TDC (255A) 2nd Gen Xeons (Cascade Lake, aka 8259CL etc). Limit around 200€ (just for a fun project).

Not sure if you find something like this for under 200 EUR already build. But there are some Supermicro 116's sub 80EUR and Supermicro X11SPW-TF sub 100 EUR (all exVAT) on eBay. Just not sure if X11SPW-TF really allows you to go full tilt with these VRM-setups. Unfortunately, you want a single-socket setup.
Serverschmiede had some Intel Barebones for 150€, but they’ve now raised prices..
Yeah I‘ve seen those X11SPW, but they’re from USA, or did I miss something in Europe?
