Check out my first novel, midnight's simulacra!
X10QBi
A SuperMicro motherboard supporting four LGA2011 CPUs and eight SuperMicro memory boards. The physical board comes in at least versions 1.01, 1.2a, and 1.21. It requires a SuperMicro AOM-X10QBi-A/L I/O board to boot (the card uses a proprietary slot). This card implements BNC/IPMI, offers two 10GigE ports via an Intel controller, and supports VGA. The chipset is Intel C602J.
Contrary to some information online, it boots just fine off a single CPU in Socket 1. It requires about five minutes to reach UEFI handoff, and goes through several dozen boot codes (some of them repeated) before doing so. Similarly, you can boot off any subset of CPU sockets, so long as there's one in socket 1, and there is working memory on board 1.
Memory boards
There are 8 slots for SuperMicro memory boards, of which there are three variants (different boards cannot be mixed):
- 10QBi-MEM1 1.01: DDR3 with Jordan Creek 1 controller
- 10QBi-MEM1 2.0: DDR3 with Jordan Creek 2 controller
- 10QBi-MEM2 1.01: 1866MHz DDR4 with Jordan Creek 2 controller
The X10QBi supports ECC memory, correcting single-bit errors and detecting double-bit errors.
The manual claims that MEM2 boards are required to use v3/v4 Xeons, but my experience is that these newer processors work fine with MEM1, so long as you have the most recent firmware.
Boot codes
If the machine immediately goes to state FF and doesn't leave, the CPU output ports are not being written to. You have either a bad motherboard, at least one bad processor, and/or at least one badly-seated processor.
Updating BIOS via BMC
The most recent BIOS is 3.2 from 2019-08-08, X10QBi9.808.
