Hey guys. Just purchased this. Intending on posting a better review after spending more time with the machine. Just letting everyone know this system does NOT support Load Reduced DIMM. It only supports DDR4 ECC RDIMM or ECC/non-ECC UDIMM. LRDimm has the same physical bus connector and same voltage but is not compatible with this system. I ordered the wrong Dimm (LRDimm) by mistake and had to get an RA and pay a restocking fee because of my error. Hope this can save you the same problem :)
