Dell 1950: How to tell what generation it is?

If you don't have a circle with a II or III then it's a I:

It's by age. So I use the HP equivalent, the DL360/380 G5. The servers were introduced in 2006 and followed the Intel XXXXX product line. The first CPUs to be supported were the dual-core Intel 5100-series. These were followed by the quad-core Intel 5300-series, and later, the quad-core Intel 5400-series.

That explains the Gen1, Gen2 and Gen3... They all used Intel 5000X chipsets and similar components.

If your server is from 2006, it's the first generation.

on the front left side of the face plate you will see a II or a III for gen 2 and gen 3. If there are no roman numerals then it is a gen I
