Hi, i've got a poweredge T410 and i'm confused on how to upgrade the ram. it came with 2 x cpus and 16gb ram from new (8 x 2gb 2Rx8 PC3 10600E). so all eight slots are populated with ram. i've read loads of articles and still find it a bit confusing. I've got 2 new 8gb ram modules (8gb 2Rx8 PC3 12800R) which I would like to add but this doesn't seem to work in any of the slots as a pair. i've tried it in A2+B2, A3+B3, A4+B4 and A1+B1) and each time the system complains about a bad memory configuration and wont boot. please can someone advise on whether I can add these two ram modules to my current config and how? or whether I need to buy another two and add four to make it work? i've updated the bios too.
