I am trying to build a high end pc for running pre-built virtual machines in Hyper V. I tested with my laptop which has i7-4710 processor with 12 GB RAM and found that the VM on Hyper V struggles to start and run, as there is not much of memory left to allocate to the Virtual machine. After researching some more about high end and custom build laptops, I found that the maximum memory they can get to is 32 GB RAM which may run short when I need to run multiple virtual machines simultaneously. So I decided to look at building a high end desktop and while researching about it, I got this forum.
Final goal is to have a high end desktop with 128 GB RAM, I may not buy all of them today, but want to be able to expand as required in future.
Following are my questions:
1. I found that the latest version i7 processor supports maximum of 64 GB, further some forums indicate that the processor cannot recognize more than 32 GB RAM.
2. So I have started looking for Intel Xeon processor (X 2) which 4 channel for RAM in each so it provides a total scalability of 128 GB RAM.
I would like to validate the above findings and request for feedback on following build specification on Intel Xeon. Note that I went for Xeon 2620 as it is less expensive compared to the latest version of Xeon.
