Hello and thanks for the help,
System:
Motherboard: Supermicro X11SSM-F Rev 1.01 with BIOS v3.3 (05/20/2024) (USED)
CPU: Intel Xeon E3-1275 v5 Quad Core 3.6 GHz with 4.0 GHz Turbo (USED)
RAM: 64GB Kingston 2133MHz DDR4 (ECC) (USED)
Power Supply: Seasonic FOCUS V3 GX-1000 1000W 80+ Gold ATX Fully Modular PSU (NEW)
Case: Fractal Design Node 804 Micro-ATX Computer Case (Windowed, Black) (NEW)
Add-on card: Supermicro AOC-SLG3-2M2 with two 64GB Optane M.2 NVMe SSDs (NEW)
No Hard Drives installed yet
Problem: My Supermicro X11SSM-F BIOS fails to boot if its NVMe M.2 SSD memory is installed.
I’m using a Supermicro AOC-SLG3-2M2 memory add-on card to add two Intel 64GB Optane NVMe M.2 SSDs to my Supermicro X11SSM-F motherboard.
According to the Supermicro website, my motherboard is compatible with this memory add-on card: <FORUM tool won’t allow me to add the “Supermicro AOC-SLG3-2M2” documentation link>
The documentation for the Supermicro AOC-SLG3-2M2 add-on card suggests the following changes to the motherboard BIOS:
Depending on the system, motherboard, and BIOS version, the following BIOS
settings may be necessary for the proper operation of M.2 NVMe drives:
• Having the CPU IOU settings set to x4x4x4x4 PCIe bifurcation. This option may
be found under BIOS Setup -> Advanced -> Chipset Configuration -> North
Bridge -> IIO Configuration -> CPU Configuration -> IOU Setting -> x4x4x4x4.
• Having the NVMe Firmware Source set to AMI Native Support. This option may
be found under BIOS Setup -> Advanced -> PCIe/PCI/PnP Configuration ->
NVMe Firmware Source -> AMI Native Support.
So I upgraded the motherboard BIOS to the latest version (v3.3, dated 05/20/2024),
reset the CMOS memory, and set the following BIOS options:
- Advanced tab->Chipset Configuration->System Agent (SA) Configuration->PEG Port Configuration->SLOT7 Bifurcation=[x4x4]
- Advanced tab->PCIe/PCI/PnP Configuration->NVMe Firmware Source=[AMI Native Support]
- Save & Exit->Save Changes and Reset
Then I installed the Supermicro AOC-SLG3-2M2 add-on card into SLOT7.
(My motherboard BIOS offers bifurcation only on SLOT7. So I’m using SLOT7 for the memory add-on card.)
Bootup fails with:
0x08=mrcWriteLevelingError 02
and
5 short beeps, 1 long beep
indicating a “memory error”.
The motherboard boots if this memory card is not installed. But fails to boot if it is installed.
What am I doing wrong?
I’d appreciate any help.
