I have encountered an error when running a memory test. Does a failed "Data Bus Stress Test" mean a problem with the RAM stick, or with the motherboard/chipset? Or could it be either?

(ie: is the data bus it's refering to in the RAM stick, or on the motherboard)

Note: I am using the Dell Diagnostics Utility (on a bootable partition).

It would appear that a "Data Bus Stress Test" in this case tested the RAM stick's bus. The "Data Bus Stress Test" failure/error indicated a problem with one of the RAM sticks.

After experimenting, I found that removing one of the memory sticks solved the problem (eliminated the error). So it was a problem with the RAM stick.
