Many years ago I picked up the old supermicro 24 bay chassis with opteron and server mobo and that worked fine for many years but I got the itch to upgrade it. So I put one of my old desktops into the case and bought new 9207-8i storage adapters here: https://www.ebay.com/itm/194910024856

My mobo had like 4 pcie slots that operated at fast enough speeds that I thought I would be fine.  It was older i7-4771 that I was using.  But I had trouble with it recognizing and running the 3 cards.  I ended up frying that board but I purchased another 1150 board off ebay with enough slots because I wanted to use the same 4771 with the 32gb of ram I have.  But alas it also is throwing errors "MPT BIOS Fault 01b" at boot some of the times but other times no errors.  I thought maybe it was because I hadnt tighted down the cards in the case because I was just testing it and that the cards maybe needed a good ground to the case from being tightened down.  When booting the system all the drives showed up so I thought I would be fine.  I booted into unraid and everything came up and seemed fine.  I decided to run a parity check last night and upon checking it today found about 1/3 of my drives as redballed.  My thinking is that this mobo also doesnt want to run these 3 cards together.  Does anyone have a recommendation for a mobo/cpu combo to run the three pcie x8 cards at speed that they know is able to run these types of cards?  It would be very much appreciated!  I dont want to break the bank but I do want to get this back online.

If those are the specific model, make sure you have enough airflow, since they have a different design from standard, which means air has to be forced through. Also you'll want to make sure they are all running the same firmware so I would flash firmware, bios and UEFI-bios on all of them, which you can all get here.

 

It is possible your motherboard doesn't have the capability to run all 3 copies of the firmware/bios at once, so consider replacing them with a 9305-24i instead, or 9400 models for a 16i and 8i, or two 16i's.

Sounds like a decent recommendation.  Not having any luck finding anything that isn't coming from China.  Is that worth the risk? I mean with regards to getting a counterfeit product.

lol... everything is made in China. I mean ok maybe it's made in India. But does that then make you feel like it's less likely to be counterfeit..? Just buy from a reputable seller that will work with you if a problem comes up. I mean I was sweating a warranty claim with Newegg over out of the box bent CPU pins. Just imagine hoping that the random ebay or Temu seller will help without ebay or Temu stepping in.
