I have two Dell servers (R710 and R610) that I'm trying to swap the memory in. The R610 is now out of warranty and has died. Rather than replace the broken pieces, I would rather condense the workloads and put the R610's memory into the R710. The R610's RAM is labeled "2GB PC3L 1Rx8 10600E-9-10-D0". The R710's RAM is labeled "2GB PC3 2Rx8 8500E-07-10-E1". Are these two types of RAM compatible? I have enough slots open in the R710 to do the swap. I just need to know if the sticks are compatible.
