T7500 Memory Population
I have a question about populating memory slots on a Precision T7500. The system came with a mere 8gb and I'm changing those out for 16gb. Is it not possible to simply use 2 sticks of 8gb? I seem to be at a loss on why I either get lights 3 & 4 on the front panel or an amber power light with 2 3 4 flashing.

It is. It can be picky about what slots you use.
From the manual:
T7500 Memory Population Rules
Your computer requires DIMMs within a channel to be populated starting with the DIMMs farthest from the processor first. This means the DIMM slots 1, 2 and 3 must be populated before DIMM slots 4, 5 and 6. In addition, when populating a Quad-rank DIMM with a Single- or Dual-rank DIMM in the same channel, the Quad-rank DIMM must be populated farthest from the CPU.
To maximize available memory bandwidth, DIMMs within a configuration should generally be spread across as many channels as possible before populating multiple DIMMs per channel. The population guidelines below help to achieve this.
