Recycled :
I am building a lot of Dell Tx500 workstations at the moment. They are coming off lease and are awesome deals.
The Dell Precision T7500 is capable of amazing RAM speeds, but Yours is currently misconfigured. It runs, but the RAM is slow. The Dell Precision T7500 runs Intel's 5520 chipset. That supports 3-channel DDR3 RAM at up to 1333 MHz if You use 1, 2, 4, or 8GB ECC DIMMs. It supports up to 1066MHz if You use 16GB DIMMs.
The Dell Prevision T7500 does something that the R5500 also does, but that the T5500 and T3500 do not do. There is a second memory controller on the T7500's second-processor-riser-card. That enables 3 additional memory channels.
Your system could be running 6 channels, all at once, if only the RAM was installed correctly. As It is, I suspect it is running 1 or 2 channels. To get the most speed out of Your RAM, install RAM in sets of 3.
To upgrade to about 16GB of RAM:
1. DO NOT buy 4x4GB DIMMs. Buy 2x1GB DIMMs and 3x4GB DIMMs to get a total of 4+2+12=18GB. This machine takes ECC RAM, either unbuffered or registered. You will need to match what You buy to what You have. (CPU-Z will tell You what You have.) Also match the clock speeds, if possible.
2. While observing all electrical and ESD precautions, pull the 2x1GB DIMMs off the riser and add the 3x4GB DIMMs there (where the white tabs hold the DIMMs on the riser.)
3. Add one DIMM to the 2 on the main board (where the white tabs hold the DIMMs on the main board.)
4. I don't think it matters where the other 3 go as long as they all go on the riser or the main board. I could be wrong about this last point. They will go where black tabs hold the DIMMs on.
Some details are available here, but it takes a LOT of digging to find out what all these Dell Precision Workstations are capable of.

One more thing...working inside to T7500 is not as trivial as working inside some gamer's home-brew rig. You will need the service manual: http://sivirt.utsa.edu/Documents/Manuals/precision-t7500_Service%20Manual_en-us.pdf
I am complete novice at computer upgrades - need to speed up my computer to run all Adobe products, AVS4You video software, surf multiple sites, currently my computer is taking sometimes ten minutes to load a file or program.
I am sure i need more ram but what type and how much and would the motherboard cope? or would i need to upgrade that too as well as the Processor?
