Select appropriate second CPU for Dell PowerEdge T430
I have Dell PowerEdge T430 server with single Intel Xeon E5-2630 v3 (2,4Ghz) CPU installed and 96Gb memory. The issue is that in this mode operating only 3 of 5 PCI express slots (user guide), and I can't use RAID adapter/NIC in 4th or 5th slot. To solve this trouble I need a second CPU and seems like more memory.
What is less expensive E5-2600 v3 CPU I need to purchase and how much memory must be added to system to minimize upgrade budget?
