    Looking for a motherboard recommendation please!

    Supermicro has some X9 and X10 Motherboards with Dual Processors.

     

    You will have enough RAM slots, PCIe sockets... I have one with dual GPUs, dual HBA's, and several Nvme drives with Adapters. Sounds like it would work for you. You wont be able to get there with Ryzen, there are not enough PCIe lanes and sockets. Sever boards are the only way to get there.

    Second on the RAM, I have seen this on two of my servers. Both times it was RAM, a single stick went bad. Once I a ebay parts build, another was a stick that was working fine for 3 years and just quit working.

     

    Reboot, and from the menu run MEMTEST, Just let it run, let it finished, it might lock up, but you can watch the progress and see about where it is and then you can figure out what stick it was. In my case it would get stuck in MEMTEST around 33gb, so I just counted the ram and found where the stick was where 32GB started in the count. I pulled that stick and replaced, BigPot! done.  The other time, I had 8 sticks, I just pulled 4 stick, ran MEMTEST, Passed, so I swapped the other 4 sticks in, ran MEMTEST, it failed, so I then pulled 2 sticks, repeated till I found the single bad stick, done.

     

    Easy Peasy, I will say it took several hours each time, the process is long and slow.

    Hope this helps.

     

    How to check if memory is running Dual or Quad Channel mode?

    in Motherboards and CPUs

    Right, if the 4 DIMM's are not matched with the speed and timing, they will run as Dual, so 2 sets of 2, I think that was clear in my original message.

     

    My question: is there a Terminal Command to check the channel mode the memory is running in. Simple question.

    Don't go making this something complicated, I can get my answer by booting into a Windows USB and running a number of checks to see. I just want to know if there is a command that will tell me before I drag out a monitor, mouse and keyboard to get the answer.

     

    Random server reboots/crashes

    HynesJeff,

     

    Check your RAM, run MEMTEST64.

     

    Explain;

    I had a random hardware crash, reboot issue for about 6 months, I looked all over for the issue, but could not figure it out. I ended up running MEMTEST64 and found some bad RAM, it was easy to find out which DIMM it was with isolation. Once I pulled the bad stick out, it was solid for 3 months, RMA'd the ram and all is good again.

    Is there a terminal command I can run that will show what its doing?

     

    Explain:

    I had a 2 kit of Dual Channel Dimms in my x99 board, bought at the same time, running in Quad Mode, I had to RMA 2 of the 4 Dimms as one was bad and I bought them as 2 kits of Dual Channel. Fast forward, Kingston sent me 2 new Dimms, but they are different than the others, on paper they should be the same.

     

    The system came back up and is running all 4 Dimms, and all is good, I was not able to verify in the Bios if they are running in Dual or Quad, and I don't see it in Unraid anywhere either.

     

    I could pull the Unraid USB and run a Windows USB and run AIDA64 or HWINFO, but I was hoping there is a way to see that info without all that.

    I searched around and found a few commands to check memory info, but non of them seemed to help with determining what Mode they were running in. (Single, Dual or Quad)

    Thanks,

    Donovan
