Hello. I am doing FEM simulations, and although they are not CFD but electromagnetics, I hope that you can still help me. I recently got a HP Z820 with dual Xeon 2643 @ 3.3 GHz and 32 GB ram. However, in the FEM simulations I do (using Ansoft software), I notice almost no difference between this machine and my previous machine, which was an Intel core i5-2400 @ 3.1 GHz. I would expect a dual 2643 to be a bit faster!

I have one idea about what could be wrong: The memory is installed as 4x8 GB, but HP recommends that you use 8x4 GB to take advantage of the Xeon's quad channels. Could this be the issue, or is there anything else ?
