My work recently let me have one of their old servers, an R710.
It had only 4GB of RAM in it, configured as 4 x 1GB DIMMs installed in A2,A3,B2,B3.
Since I wanted to use it for virtualization I decided to upgrade the memory and have bought 4 x 4GB DIMMs (total 16GB).
All the old memory is DDR3 - 8500E
The new memory is DDR3 - 8500R
When I plugged the new DIMMs into the same slots it detects as 16GB but says that ECC is now disabled because the configuration isn't right (they are not pairs). I have tried putting them in all sorts of different ways in A2/A3/B2/B3 but it just won't configure correctly. The worst part is when I put the old memory back in that then has the same error where it didn't before.
Initially I thought the memory I had bought might be wrong and that still may be true (it did specifically say ECC for an R710), but I have this nagging feeling I am doing something stupid.
Any help / feedback would be much appreciated.
