Memtest 86+ checks if the ram works as it should.
It Does Not test if the ram works well together.

So I agree with the others. Mismatched ram is not a good idea. Most of the time it causes problems.

what kind of problems does mis-matched RAM cause? My plan moving forward is to removed the mis-matched RAM and then re-install Windows 7.

Mismatched memory usually have different frequency, timing and voltage.
Windows can't run at multiple frequency, timing and voltages so either of the sticks must run at different specs than designed.

Hardware running at different specs than designed could malfunction, that's why it is a bad idea.

You can change the ram without installing Windows 7 again.
Mismatched ram can cause all kinds of problem. To many to list.
All one has to remember is always use matched ram.

As Roy has mention on one of your other threads.

Have you install a legal copy of Windows 7 with a matching legal COA key?
