Daniel,
I also have an R710 Poweredge with 4GB DIMMs and am looking to upgrade to 16GB DIMMs.
My current configuration is:

I have 2 servers build this way. I have purchased 4 each (16 total) 16GB DIMMs for these 2 servers thinking that I needed half of the 8 slots populated for them to operate.
After reading your posts to Utpal1, I take it that I should have purchased either 3 each or 6 each and re-used the 4GB DIMMS in the remaining slots. I want to get the most out of what I purchased. If I use 3 of the 4 16GB DIMMs in slots 1-3, can I mix the remaining single 16GB DIMM with 4GB DIMMs in slots 4-6?
Will this diminish the speed of the DIMMs if I mix them? I want to obtain the highest performance possible.
Thank you,
Paladin IT
