I know this are an older unit but I have got my hands on a decommissioned one that I want to setup for personal use. I also can get some decommissioned HP server memory modules but wanted to check first that they are compatible. The memory is:

HP Part Number 500205-071U (not sure what the U stands for)

This memory I believe is DIMM,8GB PC3-10600R,512Mx4,RoHS Dual Rank
