I’m not really sure what you mean from this post? Is the machine not happy with the RAM? Are you wondering if the machine can work with this RAM? Also what are you going to be using it for?
I’ve had to support a fair few T3500’s and had one at home myself. Annoyingly the machine can only take 24GB of RAM at the most. I did find however it does work if you put 3 x 8GB DIMM’s in there. I used the Crucial DDR3 ECC RAM in 4 machines and didn’t have any issue.
