*EDIT: recapping my issues --
short summary of my hardware:
Supermicro X11DPI-NT motherboard
1x Xeon Gold 6130
2x Hynix 32GB 2666 sticks
PSU Corsair HX1200
I can access IPMI but the issues I'm having :
-system does not POST.
-powered on, there is no VGA output via the motherboards AST2500 BMC.
-powered on, IPMI doesn't see the sytem as being on. Unable to power system off from IPMI as it doesn't see it as being on.
-powered off, IPMI can poweron the system but IPMI doesn't see it as powered on (and it doesn't POST and there is no VGA output)
-iKVM says "no signal"
-html5 window, similar to iKVM, says "no signal"
-no beeps/buzzers from the speaker attached to JD1 header (speaker header) even if I remove all RAM sticks
-Hardware Info shows incorrect hardware. It shows dual Gold 6126, and all 16 DIMMS populated with 16GB Hynix sticks. I'm assuming this is from Testing at factory because I have a single 6130 and only two 32GB RDIMMS. Both motherboards, the one I RMA'd and the new one I just received show this weird hardware info tree.
-the CPU is cold to the touch even after having system powered on for 30+ minutes
What I've tried:
-confirmed the 8pin CPU power is connected (I also tried connecting two of the 8pins from PSU even though I only have one CPU ).
-confirmed the 24 pin is connected properly. The BMC heartbeat is pulsing, which means BMC is fine. The power LED on the board near the frontface headers is green, which means the board sees power.
-confirmed that I have the proper DIMMs populated P1DIMM-A1 and P1DIMM-D1 for a single CPU with two sticks of RAM. This info is on the quick reference guide which came with the board, also it is in the manual.
-booting with motherboard outside the chassis with no difference.
-removing CMOS battery, resetting CMOS by jumping the CMOS pads, and reinstalling battery (according to the manual).
-Tried altering the amount of turns/torque on the LGA3647 CPU heatsink. The manual states no more than 12lbf. I think that is "pounds force" and because scale is absent it is probably 12 lb inches. I don't have an inch lb tq wrench or tq screwdriver so I've been trying to guess what "feels" like 12 lbs inches.
-socket pins look good. no bent pins. I confirmed using my smartphones magnifyer app to zoom in reallly close.
I RMA'd the first board because when I couldn't get any beep codes I figured the board was simply dead. But I'm having exact same issues on this 2nd board. Both boards are the X11DPI-NT. I find it hard to believe two boards are dead. The first board I bought from a reseller on Amazon. This 2nd board I bought from Wiredzone.com
and was drop shipped direct from Supermicro in San Jose CA.
What I've not tried yet:
- I've not tried flashing BIOS. To do this I need to acquire an IPMI license (about $20 I think). Or I may try a USB stick with FREEDOS and the BIOS files on it, plugged direct into the board. I'll have to read up on how to do this exactly. I'm unsure what my current BIOS version is.
- I've not tried replaceing CPU. Maybe I have a bad CPU. I'm seriously considering this one as I have only 7 days before returns are no longer accepted.
*update: I talked with the CPU seller and they issued me an RMA on the CPU. I'm getting crazy with these RMAs, I'm telling ya.
*also had a chat with friends on reddit in r/homelab...from the dialogue there it seems if it were bad RAM then I would've heard beep codes. Since I'm not hearing any beeps it is likely bad CPU or PSU. Another indication of bad CPU, it is cold to the touch even after being powered on for 30+ minutes. I have a few spare PSU from other servers that I will try tonight. But I still have my RMA return label if I need to mail the CPU back.
