error code 2F00:0119 Msg: system memory failure. read BFFFFFFFFh at
adress 94104514h. suspected memory component located on the system
board, at board at label channel a dimm 1. I ran systems diagnostics
test on a 4700 dell on my memory and I get this error everything time
during the test and it's not able to complete. I replaced my modules
and motherboard and I still get the same error when I run the test. I
need to know if anyone has ever seen this and know exactly what it
means? thank you.

I've already replaced the motherboard and the ram, I still get the same error.

Have you tried replacing the processor?  Often times there can be a
defect in the processor itself that masks as a RAM problem.  Since
you've replaced the mother board and RAM, try replacing the processor
chip.

I haven't tried replacing the processor yet. I'll give it a  try that. thank you.
