Supermicro ошибка ba

I’ve been testing my dual CPU Supermicro X9DR3-LN4F+ board for the past couple of weeks with a single CPU and 16GB Ram (2 x 8 GB). Everything has looked good and today I added the second CPU and it booted fine with no issues. After this, I added another 16GB RAM and now I can’t get past the System Initializing with BA code. Looking at Supermicro support it looks like this BA code refers to a memory related issue.

The memory I’m using is supported by the board and I’ve tried different sticks in the new slots so I’m pretty sure it’s not the RAM. Also, I’m following the recommendation from the manual for populating as it says:

2 CPUs & 4 DIMMs
P1-DIMMA1/P1-DIMMB1
P2-DIMME1/P2-DIMMF1

Any ideas on what I can try next?

Hi Patrick,

I’ve tried the following so far:

1 CPUs & 2 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1

2 CPUs & 4 DIMMs (BA Code)
P1-DIMMA1/P1-DIMMB1
P2-DIMME1/P2-DIMMF1

2 CPUs & 3 DIMMs (BA Code)
P1-DIMMA1/P1-DIMMB1
P2-DIMME1

2 CPUs & 4 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1
P2-DIMMC1/P2-DIMMD1

2 CPUs & 4 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1
P2-DIMMG1/P2-DIMMH1

I’m starting to wonder if there is an issue with the E/F DIMM slots.

I’m using the Supermicro SNK-P0048P heatsinks on my E5-2670 Xeons.

The reason I asked about heatsinks is that I have heard that non-standard heatsinks in some motherboards can damage the PCB and cause this issue.

I think I had a V3 motherboard BIOS which gave a similar error until it was flashed to a V4 BIOS.

That’s good to know about the heatsinks as I was thinking about upgrading them at some point. My BIOS was updated to the latest so I should be ok there.

I just tried the following:

2 CPUs & 12 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1
P1-DIMMA2/P1-DIMMB2
P1-DIMMA3/P1-DIMMB3
P2-DIMMC1/P2-DIMMD1
P2-DIMMC2/P2-DIMMD2
P2-DIMMC3/P2-DIMMD3

2 CPUs & 3 DIMMs (Boots, but only shows 16GB)
P1-DIMMA1/P1-DIMMB1
P2-DIMMG1

2 CPUs & 4 DIMMs (Boots, but only shows 16GB)
P1-DIMMA1/P1-DIMMB1
P2-DIMMG1/P1-DIMMH1

2 CPUs & 18 DIMMs (Boots, only shows 96GB)
P1-DIMMA1/P1-DIMMB1
P1-DIMMA2/P1-DIMMB2
P1-DIMMA3/P1-DIMMB3
P2-DIMMC1/P2-DIMMD1
P2-DIMMC2/P2-DIMMD2
P2-DIMMC3/P2-DIMMD3
P2-DIMMG1/P1-DIMMH1
P2-DIMMG2/P1-DIMMH2
P2-DIMMG3/P1-DIMMH3

2 CPUs & 18 DIMMs (BA Code)
P1-DIMMA1/P1-DIMMB1
P1-DIMMA2/P1-DIMMB2
P1-DIMMA3/P1-DIMMB3
P2-DIMMC1/P2-DIMMD1
P2-DIMMC2/P2-DIMMD2
P2-DIMMC3/P2-DIMMD3
P2-DIMME1/P2-DIMMF1
P2-DIMME2/P2-DIMMF2
P2-DIMME3/P2-DIMMF3
P2-DIMMG1/P1-DIMMH1
P2-DIMMG2/P1-DIMMH2
P2-DIMMG3/P1-DIMMH3

Something seems to be happening with the memory slots next to the second CPU. If I populate the G/H slots (without E/F slots), the machine boots, but the sticks aren’t recognized in Windows. If I populate the E/F slots it never boots and always stops at the BA code. All the slots (A/B/C/D) next to the first CPU seem fine.

Hi Piglover,

I’m using the V1 Xeons and I’m running Bios version R3.2. I had previously flashed all my components (Mobo Bios, Mobo IPMI and Dell H310 HBA Firmware) to the latest versions before starting my full testing as I was hoping to avoid issues like this.

Thanks for that last idea, Piglover!

I had quickly looked at the pins when I bought the board (from eBay), so I took off the second heatsink/CPU and took another look at the CPU area with a magnifying glass. The pins still looked ok (not that I could accurately confirm as I think I need a better magnifying glass/light to really look closely), but I did notice bits of fluff on and between the pins. I gently vacuumed the area using a soft brush attachment and then reattached the CPU/heatsink. I then tested the following configurations again:

2 CPUs & 3 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1
P2-DIMME1

2 CPUs & 4 DIMMs (Boots)
P1-DIMMA1/P1-DIMMB1
P2-DIMME1/P1-DIMMF1

This is the first time I’ve been able to boot when slots E/F have been populated! For my next two test I ran 2 DIMMs in each section followed by all slots filled:

2 CPUs & 8 DIMMs (Boots, but only shows 48GB)
P1-DIMMA1/P1-DIMMB1
P2-DIMMC1/P2-DIMMD1
P2-DIMME1/P1-DIMMF1
P2-DIMMG1/P1-DIMMH1

2 CPUs & 18 DIMMs (Boots, but only shows 144GB)
P1-DIMMA1/P1-DIMMB1
P1-DIMMA2/P1-DIMMB2
P1-DIMMA3/P1-DIMMB3
P2-DIMMC1/P2-DIMMD1
P2-DIMMC2/P2-DIMMD2
P2-DIMMC3/P2-DIMMD3
P2-DIMME1/P2-DIMMF1
P2-DIMME2/P2-DIMMF2
P2-DIMME3/P2-DIMMF3
P2-DIMMG1/P1-DIMMH1
P2-DIMMG2/P1-DIMMH2
P2-DIMMG3/P1-DIMMH3

It looks like the E/F slots are working now as they are no longer preventing the board from booting in all these tests. However, it looks like there may still be an issue with the G/H slots as they are not showing up in Windows.

Maybe there is an issue with the pins that I only partially fixed by reseating the CPU?

this didn’t happen to me until after irremovable USB connector form under the motherboard. i guess when screwing it it the chassis i didn’t see the test bench USB mouse connector had slipped in just under the board where the I/O should have been (had this board come with one). loosen a few screws lift slightly as to not hurt the PCB and pull it out. me thinks damaged PCB with all that an tower coolers. it worked prior and i had just bought this board to fix a broken one. seems like a WEAK board usually PCBs aren’t so fragile.

EDIT: looks like it was either bad or dirty stick of ram after doing some swapping and lazy trial and error.

Board clearly says X9DRI-LNF4 where as the bios says X9Dr6-LNF4

Does it work with the «X9Dr6-LNF4» bios? If yes I would make sure that it’s the right mainboard by comparing spec sheets, manuals or other sources.

Open a ticket with supermicro support and ask for the bios version 2.x for this mainboard. Try to update to this version first and then try the v3 bios.
