PowerEdge 2950 II Memory

What is the difference in the RAM memory between a PowerEdge 2950 and a 2950 III? and even more important, what should be the memory option when a memory configurator only shows the two first?

For example: The specs for a 8GB (2x4) RAM from Crucial for a 2950III is: CT782905 for a 2950 is: CT553023; so, what would be the option for a 2950 II????

How can I determine that the 8GB memory part: CT2KIT51272AB667  would be compatible with a 2950II???

This is going to sound silly but the best way to determine what memory you need in your Dell server is to give the service tag to a support technician.  They can look up what is compatible.  Just go here: http://support.dell.com/ and click the chat link.  Shouldn't take more than 10 minutes... they can get that info pretty easily with the service tag.

The PowerEdge 2950 II and III have the same bus speed (only 1066/1333) and same memory support (8x8GB=64GB), but the 2950 III will support the 5400-series processors.  The 2950 I also supports 667 with some lower-end processors not available in the next two versions, as they support only the higher rated procs.

Bottom line, if shopping for a PE 2950 II, choose the 2950 III ... just remember the one difference that the 2950 III is the only one that supports the 5400/QC processors.  Other than the processor, if it works in the III, it will work in the II.

As for the difference in the memory between I and III ... the only difference is that the III can support the 8GB/4R DIMM's, where the I is limited to 4GB/2R DIMM's, hence the difference in maximum memory supported.  Both require Fully-Buffered, ECC memory, so the CT2KIT51272AB667 will not work.  In fact, as it is not a FB-DIMM, it will not even fit.  If you want an 8GB (2x4GB) upgrade, you would need either of the other two you listed:
