Sorry for the delay.  We have received confirmation that the part listed (HMT351U6CFR8C ) has the wrong specifications listed on the Hynix website.  As suspected, it is not an ECC DIMM, and this system explicitly prohibits non-ECC DIMMs.   Hynix indicated that they will update the tech sheets accordingly. They indicated that HMT351U7CFR8C-H9 is the equivalent ECC UDIMM. Please let us know if you need additional information that we can help with.

We also tried a few more options with ecc and none of them worked. The processor is    thank you
