[BBLISA] RAM speed difference?

[Scott Ehrlich]

I'm pricing out some servers (from Dell) and deciding between their 1955 blade 
server and a 2950 2U server.   I learned the 1955 has only 4 RAM slots, whereas 
the 2950 has 8.  Thus, I could populate with 4 x 4 GB modules, or 2 x 2 GB 
modules (cost savings).  But, for compute-intensive work, where the majority of 
a program will work between CPU and RAM, how much of a cost, compute-wise, is 
there, between 4 GB and 2 x 2 GB?

I could go with 10 blades, or 10 2950 machines.   The benefit of the 2950 would 
be more slots for RAM and, with its architecture, easier to manage and expand 
(I work with two of the 2950 machines anyway, and have seen the 1955).

I'm not a/the programmer.  I'm just relaying, and using my resources to get the 
best hardware that fits the need.

Thanks for insight/feedback.
