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. The T640 accepts cpus up to 205W so I went for that. If your CPUs are above 165W each, make sure to get a pair of high wattage heatsinks from Dell ( Dell P/N: 0VX3D ) Here's a 0489KP heatsink (stock, left) next to a K2PNJ heatsink (right). 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.
