Memory boot issues

[red_vette]

I purchased a matched 16 set of Samsung M393B1G70QH0-CK0 8GB PC3-12800R memory off eBay. I have tried a couple different combinations of them in two SuperMicro servers. They have X9DRi-LN4F+ and X9DRi motherboards with two Xeons each.

I pulled the existing memory kits from each server, installed this new set and booted the servers. Both got stuck on boot sequence B7, which according to SuperMicro is a memory error. I have tried everything from all 16 sticks, down to the minimum 4 which is required for dual socket setups. Is it possible for an entire set of used ram to be bad, or is there something I need to do with the motherboard when swapping memory?

I think with Xeon E5's you can do 1 DIMM per socket. Maybe try that?

I'd also check the backside of the motherboards for shorts, but it's odd that you're seeing it on two motherboards.

The SuperMicro manuals only show a configuration of 4 dimms for 2 cpu minimum. I also doubt it's shorts since the memory that came with each system works fine. I was wanting to go from the 64GB to the new 128GB set.
