Have you tried moving known good memory modules to different slots?
Did you install the memory following these T7600 guidelines?
Memory Module Guidelines: To ensure optimal performance of your computer, observe the following general guidelines when configuring your system memory:
Memory modules of different sizes can be mixed (for example, 2 GB and 4 GB), but all populated channels must have identical configurations.
Memory modules must be installed beginning with the first socket.
NOTE: The memory sockets in your computer may be labelled differently depending on the hardware configuration. For example, A1, A2 or 1,2,3.
If the quad-rank memory modules are mixed with single or dual-rank modules, the quad-rank modules must be installed in the sockets with the white release levers.
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).

======In addition, you say your T7600 is running BIOS A18? Looking at Dell Drivers webpage the latest BIOS is A16 --> https://www.dell.com/support/home/us/en/04/product-support/product/precision-t7600/drivers
