The heartbeat light noes not blink and the controller does not show up in the output of lspci, when it is working it does show up: ``` 41:00.0 Serial Attached SCSI controller: Broadcom / LSI SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02) ```

Actually, I did get hynix ram, and it has been just fine. It was certified by supermicro, I think the ram I had before was just too slow

Is my face red! Latest Arch Linux running the current LTS kernel. Supermicro CSE-847E16-R1K28LPB Chassis with BPN-SAS2-846EL1 24-port 4U SAS2 6Gbps single-expander backplane BPN-SAS2-826EL1 12-port 2U SAS2 6Gbps single-expander backplane I should add that both backplanes disappear. I have 2...

I have 2 Supermicro H12SSL-CT motherboards, one of them has been doing something strange. When I reboot, the SAS adapter gets disabled, if I shut down, pull the power, and then boot - it comes back - but only until I reboot the system - then poof! it is gone! Any ideas on what I should look at...

I should thank everyone, I ordered new ram from supermicro and it is working like a charm!

I also did try it with and without any adapters - same issues. I also looked at the board and could not see any damage, and I ruled that out after the second board gave me the same issues with the same CPU AND a different CPU

I installed the CPU, and ram from the one system in question on another board, and the exact same issues showed up, same DIMM slots were bad. So I concluded that the ram is either bad or more likely not compatible with the board. So I returned the ram and ordered some PC3200 direct from...

You guys have been fantastic! I have reseated the CPU and carefully inspected it and the socket, I was unable to find any damage, dirt, oil, etc. I have tried multiple memory configurations I have reseated all memory sticks multiple times I have installed washers below the motherboard pegs on...

nope, I installed some washers and now only 2 sticks show up. hopefully the board is not damaged and the ram is not bad. I have another server to build with the same board, that should tell me if there are issues with the motherboard or ram

Thanks @nabsltd , I think that is it. the chassis I am using is used and I think part of it may be rising up and touching the motherboard. The problem came back when I installed a video card now it can only see 128 GB of ram. I will need to figure out how to add some insulation or tighten where...

Thanks! I do not have a misplaced motherboard standoff, I checked before I posted I can reseat the CPU, I will give that a shot There are no errors during post and no errors in the IPMI The big question I have is this: Milan does not like Hynix LRDIMM Really? Whats that about? I will look...

I just got a SuperMicro H12SSL motherboard and an AMD Epyc 7313 processor. The board boots up just fine and is running Linux like a champ - but only with half the ram installed. But I got 8x64GB memory sticks, and if I put in more than half of them the system refuses to post. I can get into the...
