Our R810 has a single processor and came with 32GB (16 2GB) memory modules installed on A1-A8 and C1-C8. I wanted to expand the memory to 64GB. I bought 8 8GB modules. I first of all took out all the existing memory and put 4 8GB modules at A1,A2,C1,C2 and that worked OK. At that point, still had 32GB and seemed to accept the new memory. Then I added the other 4 8GB modules at A3,A4,C3,C4. Under Task Manager, it still says I have 32GB of memory. Under System Information it said I have 64 GB Installed Physical Memory and 32 GB Total Physical Memory. Am I limited to 32GB with 1 processor? I also get the "memory configuration not optimal" warning when I boot up. If I can expand beyond 32GB without installing additional processors, then how is it done? What memory configuration will work?
