Some Tips about using a Dell PowerEdge T640 as a Workstation (or Frankenstation)
Rationale As much as I liked my T4X0 machines (T430, T440) with RHEL, I started to feel limited in terms of PCIe slots, HDD bays, DIMM slots and CPUs. I have slowly started to decommission the T4X0 machines to replace them with T6X0 machines. The T640 was a little more difficult to make into a silent workstation than the T630's so here are a few notes to help others: CPUs Nothing fancy here.

RAM Most of the Xeon Scalable 2nd Gen literature mentions DDR4-2633 or above but 2400 and 2133 LRDIMMs do work fine too. I'm currently using 16 x 32gb 2133MHz LRDIMM with my Xeon Platinum 26C/52T 8269CY CPUs: # memconf memconf: V3.15 16-Jul-2019 http://sourceforge.net/projects/memconf/ Dell Inc.
