I don't use Unraid, but I have been following this thread and thought I would share my experience of the X11SCA-F with ESXi 7. After a lot of tinkering, I have managed concurrent use of iKVM and the passthrough of onboard iGPU and 2x graphics cards (RTX 4000 & T1000). BIOS 1.2 (X11SCA9.C05): Load Optimised Defaults Primary Display = PCI Primary PEG = Slot 4 (RTX 4000) Primary PCI = Onboard Internal Graphics = Enabled >then last, set the following: Option ROM, Video = UEFI save & reset server starts to POST and before completing, it reboots once, then boots fully into ESXi and is fine after I needed to activate the passthrough of the 'Processor Gaussian Mixture Model' PCI device to allow the 2nd GPU to remain Active, which was odd, but not a problem. All persists on reboot. IPMI version 01.73.13. I had this working a year ago with a Quadro P4000 and P620, but in an attempt to resolve an NVMe issue, I removed the GPUs, upgraded the BIOS to the current 1.6a and tried several other changes, but was not successful. I then installed my newer GPUs ...and entered the world blank screens and CMOS resets noted by others. With BIOS 1.6a, I had managed to get iKVM, iGPU and a single GPU to work using the settings above, but keeping the Video Option ROM = Legacy. For 2 GPUs I needed to revert to my last known working BIOS 1.2. I have a few BIOS files between 1.2 and 1.6a, so I could try these, but as it works now, I probably won't bother. X11SCA-F PCI slots: Slot 7: Broadcom 9400-16i (16x HDD) - Passthrough to OmniOS Slot 6: AOC-SHG3-4M2P (3x M.2-NVMe & 1x M.2-PCIe) - Local Slot 5: USB-C from motherboard header Slot 4: Nvidia Quadro RTX 4000 - Passthrough to Win VM (disable before VM shutdown) Slot 3: gap Slot 2: Nvidia T1000 - Passthrough to Win VM (Parsec only, no Gamestream) Slot 1: Intel X20-DA2 10Gbe NIC (PCIe cable to AOC-SHG3-4M2P) - Local M.2-2: Intel Optane 900P - Local AHCI: SSDs - Local iGPU: UHD P630 - Passthrough to Win VM

Lambdatek UK. 2 showed up in stock on a Sunday afternoon, so I grabbed one!

Yes! I received the Intel E-2278G a week ago, and 4 no. 32Gb ECC UDIMMS. I just booted for the first time into ESXi showing 128Gb of memory. the DIMMS are: 4 no. "32GB (1x32GB) Samsung M391A4G43MB1-CTD DDR4 ECC UDIMM, PC4-21300 (2666)" I'll carry on with the build now.
