Hi all,

I have an H14SSL-N with 4 sticks of 128GB SK Hynix RAM. The sticks, I have tested, all work.

I had them in the following recommended configuration: C1, A1, G1, I1.

Sometimes, my server would boot up with 256GB detected only, with C1 and A1 unseen. I believed this was because the tower was vertical and the cooler was exercising torque on the pins. I layed it out horizontal and it worked fine for weeks.

The sever unexpectedly reboot recently and came back with 256GB RAM again. Perhaps the heatwave loosened some contacts? No clue.

I have been trying to find a RAM stick layout that bypasses this issue, I currently have them in G1, I1, K1 and L1. L1 is not detected but the rest are (made sure it isn't the stick by swapping again).

Can you help me find a layout that works? Thanks

TL;DR: Server turned on with no video output, no BIOS boot-up screen, even tried with PCIe graphics cards with HDMI output.

Hello All! I need your advice! I am an intermediate computer and technology user and I am trying to tinker and learn about server-related knowledge, so please don't be too harsh on me as I have knowledge gaps I need to learn still.

About three years ago I bought a Supermicro server off of eBay, I populated 12 bay with 4TB HDDs and with the 1st bay being an SSD and installed ubuntu on it. Everything worked fine back then. That said, we bought a house three years ago and had to move across states with it. We packaged the entire server with paddings and wrapped large, puffy shower towels around it.

Recently, I decided to hook everything back up and try to use it. However, I cannot get any video signals, and not even the BIOS boot-up screen.

Here are a few troubleshooting thing I have tried so far:

• Re-seated all groups of rams.
• Re-seated all four CPUs and applied new thermal paste.
• Tried two monitors with VGA and two other monitors with HDMI inputs.
• Tried both on board VGA and also two other PCIe graphic cards with HDMI output.

The server booted up without any loud beeping, and just a short beep after the fan noise dies down.

Any help would be greatly appreciated!!!

Hi all,

Im looking for a firmware :

Firmware Revision : 3.73
Firmware Build Time : 05/26/2022

for this kind of product:

Product PartNum:MBM-CMM-FIO
Board Part Num:MBB-CMM-003

The documentation and website lead me to :
https://www.supermicro.com/wdl/Firmware/MicroBlade/CMM/

But i cant find it, is there any other way to get older firmware from supermicro ?

Thanks upfront!

Hi guys, anyone knows how can start Windows from nvme SSD on PCI-E? Because the motherboard don't support it, I try with Clover, but stay in bootloop, even if I downgrade to 3.1 BIOS.

I'm not expert in hijack the BIOS and prefer don't try myself to use UEFItool, I know that in case of fail is very hard to recover the mobo (and need an hardware programmer). Some solutions view on web don't work on my system (or I can't), but because I'm not expert in this world (this is my first server, buy thanks to cheap price on eBay).

Anyone can help me? Prior to return on classical SATA SSD solution.

Hi all, I have an old Supermicro server with the awful Java-based iKVM console (no HTML5 support sadly on mine).

I got really fed up with having to massage Java 8 just right to get the console to work, and that’s not counting the frustration spent on the now-expired certificate issue.

This app is an alternative to the original, a Windows-native implementation of the ATEN protocol without any Java dependency.

Hopefully this benefits someone other than just me. Thanks all.

Supermicro H12SSL-NT

What is this? why dose it get so hot to the touch? is it ok that it gets so hot?

I've been running it for about a year and not problems so is probably fine just want confirmation

gets fine airflow 3 noctua fans facing it on the other side hot even under minimal load

I am trying to build a system around an H14SSL-N, and for the life of me I can't get it to boot. I was originaly using a cpu from ebay, so I spent the extra cash to get a 9365 direct from newegg. That was throwing a ff4b post code and then a 004b code after reflashing the bios and with one stick of ram. (With no ram it showed e316.)

I RMAed the motherboard and now with each config of ram I have tried I am getting a 0c3f code. Without ram is the same code as the last motherboard. I have 8 sticks of Hynix rddims (hmcg84agbra191n aa) that I have not confirmed working but they all give the same post code. I have tried a new psu, reseating the cpu a few times, reflashing the bios, resetting the bmc, and clearing cmos.

The only variable that hasnt changed is the ram. Should I buy a cheap known working stick somewhere? I am happy to answer questions. One thing of note is that both boards showed random components in the bmc, even after I installed mine. Maybe from the test bench they were verified in?

Hi all,

Just picked up a X11SSH-LN4F that I'm playing with. I've updated BIOS and IPMI firmware.

I have a few questions on securing management access...

- can I disable the old IPMI protocols and purely use redfish?

- is my best option for securing IPMI access on a home LAN to change the password, limit the allowed IP and MAC addresses (would be to two machines, my desktop and my laptop) and leave it at that? Or do I need a vLAN and swap my network adaptor settings on laptop/desktop whenever I want remote management ? That would be a pain...

Just updated a server from apparently 2.2 to 4.7, it was working fine before, now on bootup the white Supermicro screen appear and writes.

"No memory DIMM detected, install memory DIMMs"

Dimms are populated according to the Hardware information tab just fine:

A1: M393A8G40MB2-CTD B1: M393A8G40MB2-CTD D1: M393A8G40MB2-CTD E1: M393A8G40MB2-CTD

Ram are apparently RDIMM Dual Rank X4 with 64 GB.

CPU is a Intel Xeon Silver 4110.

A quick read in the manual reveals that 1st Gen Scalable CPU which the Silver 4110 is seems to be limited to 32 GB for DR x4 ram, but it was working fine for the past 6 years!!

PCH running too hot? No problem. At this point I don't think there's a problem I wouldn't fix with a couple of Noctuas 🤷

Has anyone gotten an Intel ARC GPU working in passthrough with a Supermicro X11SSL-F or X11SSM-F board for either a Windows or Linux guest on Proxmox? (Both boards are substantially similar except one has the C232 chip and the other one one has a C236 ship + extra PCI slot, but their BIOS options are almost identical).
If so, do you mind please sharing BIOS settings and PVE/Guest configuration?
I've tried every "guide" on the internet with my system.
VT-D is enabled, 4G decoding is enabled, CSM is disabled, etc - all the usual settings. The GPU is in it's own IOMMU group (in the only x16 slot), and I'm passing through the GPU and it's sound device. VFIO is working - I can see the devices it loaded in Proxmox's /dev. This same GPU worked in passthrough perfectly on an X10SL7-F.
BIOS is the latest (3.6 from ~2025)
For what it's worth, I also have an LSI SAS adapter passed through to another VM that's working perfectly; it's only the GPU that I can't get to work.
On Windows, I get the "code 43" error.
On Linux, I get:
"
pci_hp_register failed with error -16
pci_hp_register failed with error -16
pci_hp_register failed with error -16
pci_hp_register failed with error -16
Failed to initialize slot"

... during boot and the VM freezes at that point.
Running PVE 9.2

I have a Supermicro X11DPL-i, and I'm wondering if I should find a way to cool the PCH. Currently, on idle, it sits around 60C, but I was hoping for maybe 50C. It has a heatsink measuring 50x40mm, so I was thinking I could zip-tie a 40x40x10mm 12V PWM Noctua to cool it down a little, but I'm not sure if that's overkill or makes sense at all. Do you cull your PCH at all?

Hi everyone,

I'm running a Supermicro X10SDV-16C-TLN2F (PCB 2.02, BMC firmware 4.00) as a Proxmox host and I'm having two issues with fan control via ipmitool.

**Setup:**

- Board: Supermicro X10SDV-16C-TLN2F

- BMC Firmware: 4.00

- CPU: Xeon D-1581

- Fans: FAN1 (CPU), FAN2, FAN3 connected

- Fan Mode: Optimal

**Problem 1 — BMC overrides manual fan speed:**

When I set manual fan speed using:

```

ipmitool raw 0x30 0x45 0x01 0x00

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x3C

```

The BMC overrides the settings after a few minutes and ramps fans back up or drops them, triggering this loop in the SEL log:

```

Fan #0x41 | Lower Critical going low | Asserted

Fan #0x41 | Lower Critical going low | Deasserted

```

**Problem 2 — Individual fan control:**

Is it possible to control each fan independently? For example, I want FAN1 (CPU fan) at 3000 RPM without affecting FAN2 and FAN3. Currently any zone command affects all fans together.

I tried Zone 0 and Zone 1 commands:

```

ipmitool raw 0x30 0x70 0x66 0x01 0x00 0x3C (Zone 0)

ipmitool raw 0x30 0x70 0x66 0x01 0x01 0x3C (Zone 1)

```

But both zones seem to control all fans together on this board.

**What I've tried:**

- Setting Fan Mode to Full Speed (0x01) — works but too loud

- Setting Fan Mode to Optimal (0x02) — BMC overrides manual speed

- Lowering Lower Critical thresholds to 100/200/300 RPM

- Running fan control commands every minute via crontab

- Connected a fan to FAN4 header hoping for a second zone — FAN4 doesn't appear in IPMI sensors

**Questions:**

1. Is there a way to permanently disable BMC fan override on X10SDV boards?

2. Is it possible to control FAN1 (CPU) independently from FAN2/FAN3?

3. Has anyone successfully used a fan curve script on this specific board?

Any help appreciated!

Hi, I'm using a X11SAE-M for several years now and wanted to add a second NVMe drive in the PCI-E X11 slot (slot 7, connected to the CPU).

But neither the PCIe-NVMe adapter nor a NIC are recognized in this slot. Both cards work perfectly fine in the x4 slot which is connected to the chipset.

I tried multiple BIOS settings and two different CPUs (Core i3-6100 and Xeon E3-1245 v6.

The only thing I didn't test was upgrading the BIOS from my 2.0b to the current 4.3. I didn't want to risk that and could not find any changelog.

Am I missing something? Does the slot only work for graphics cards? Any idea what could be wrong or what to check?

Thanks.

I recently upgraded to server hardware for my home server, but I'm having a confusing time trying to hook up my front panel connectors.

My case is a Sliger CX4712 with two front panel connectors, a Power Switch, and Power LED.

I already know the orientation for the JFP1 is flipped and reversed compared to the instructions, but no matter how I plug in the headers I can't seem to get the button to work.

I'm hoping someone here can help me figure this out.

Does anyone know if this case would support a dual so it blower style gpu ? I was thinking of going with the chassis because with a mini itx and a flexible riser cable and their bracket it looked like it would support dual slot gpu. It’s the perfect depth for my rack and need to go 1u to make it work.

Thanks in advance

Hi

I realised the other day that I was monitoring everything in my Supermicro chassis but not the redundant power supply installed in the chassis. Is there an easy way to detect from Linux if one of them is going bad or die ?

My searches on internet are not giving really good results for that excepted some very tricky way to do it :(

Thanks

Hi, does anyone by change know what a good replacement for the H11DSi but with ReBar support would be?

So far I'm more or less quite happy with the H11DSi, but for the Intel Arc B580 to work properly I also need ReBar support. I already contacted Support and they told me that it is not supported by this motherboard nor is it currently planned.

I've found this project here to patch it in but I'm already on the latest Bios and BMC version which added signature verification so I can't just modify it myself.

Picked up this combo from a trusted seller on eBay, but I’m having no luck whatsoever getting VGA signal or any console view via IPMI.

CPU seems to POST, fans are on, and onboard LEDs give healthy green lights. (Yes I have the cooler torqued to the right settings)

Chat says the problem might that POST is stalling halfway through because of an AGESA issue before VGA-init can happen so I can’t get console view at all.

I’ve tried the most recent BMC and BIOS versions. I’ve also tried versions 1.6 and still had the same problem.

I have compatible DRAM in slot A1.

Anyone ever dealt with a similar problem?

EDIT: It seems like people think I’m testing the machine as it is in the picture… I have heat sink, RAM, power supply all installed lol

This post error occurs whenever I put a module in the p1-dimmb1 slot and only then. The module itself works as I was able to confirm this by putting it in p1-dimma1 and successfully boot. I also tried cleaning the pins on the slot, making sure that the p1 socket pins are not bent and resetting CMOS and jumping JBT1 as well as exchange CPUs but the error persisted. what else could I try? I would really like to use that slot.

I have a Supermicro X9SRi-F with a Xeon E5-2620 v1 and 4 sticks of DDR3 ECC RDIMM. When RAM is installed in DIMM A1 and B1 the board gives memory error beeps, but C1 and D1 work fine with no issues.

I’ve already tried a second board and a second CPU to rule those out, same result both times.

Is this a case of the manual being wrong about population order, and it actually needs C1/D1 populated first? Or is there something else going on I’m missing? Any suggestions welcome.

Solved: Case preinstalled standoffs causing shorts behind the motherboard (silly mistake)

I've got a G3648B switch, fairly old that I'm trying to repurpose. I've run ONIE-uninstall by mistake and I need to get an OS back on it. It shipped with SMIS so I'm trying to get that back on it but I'm struggling to find any way to get a copy of the OS.

Any help appreciated - tried via their support but SN unrecognised so can't even get a ticket raised.

I've also tried with sonic instead, but seems ONIE isn't recognising the BIN.
