No.  You have 2GB UDIMMs and 8GB RDIMMs.   You cannot mix them.  They have to be all RDIMMs or all UDIMMs or the server will not start or POST. Regards,  
Hi, We  have a Power edge R710, we want to add more memory to this server, right now it has 16 GB memory. we did bought 2X 8 GB memory. yesterday for the first time I opened the server (it is in a rermote data center) and findout that there is still 2 X 3 empty memory slots for each processors. and also findout that the current memry modules are 8 X 2 GB memory. I did try dirrent combenation of empty slots (of the 2X3 empty slots ) but or the server wont start or it starts but did not recognized the new memories. Question: Can we mix the 8GB memory module  with the 2 GB memory module? or we have to buy only 2 GB memory? or we can replace all the existing 2 GB memories with new 8 gb Memories modules?   Thanks
Memory issue R710
