Trying to build a low-ish costing server used for minecraft
. I am stuck in a tough spot. I am able to get 32gb DDR4 2400 Memory for cheaper than 32gb ddr3 1600! Is there really a big difference? Anyways. for a build using ddr4, although it is much cheaper and higher performance than ddr3, the build itself then cannot use the mobo and cpu I had planned. When I was looking for an lga1151 mobo, I found them to be much more expensive with lower cpu speeds? Which would be better?
32GB DDR4 2400 + Intel Xeon E3-1225 v5
or
32GB DDR3 1600 + Intel Xeon E3-1231 v3
