I'm trying to determine if a specific memory module (which I have not yet acquired) will work with my server.
My server is an Acer Altos T310 P3 server, and currently has a single 8GIG DIMM in it. The DIM inside is an 8GB 2Rx8 PC3L-12800E-11-13-E3 module made by Kingston. The memory module I'm looking to acquire is a 1Rx4 PC3L-12800R-11-13-C2 8 gig module made by Hynix.
What does the "E" and the "R" stand for, and what are the chances that the memory is compatible with current memory and server (I'm speculating the E is ECC, the R is registered, but I don't understand what the difference is - if there is any). Both the existing and new memory claims to be ECC memory.
(Acers specs for the system are here - I see that they recommend against mixing 1R and 2R memory - I'm wondering if I should take the punt - the module is only about US$40)
