Hi again Derek,
I can understand your feelings. When you tested the memopry with Memtest 86+ did you run it for hours ? This is how it should be done:
Memtest86+
http://www.memtest.org/Insert one stick of memory in slot 1 and run Memtest on it for at least
10 complete loops/cycles and if there are no errors then swap it over with the next one and continue untill you have checked all modules.
If you have any errors the module is faulty.
If you have any faulty modules you will have to return the whole kit as they are matched.
Post back when you have done that with the results.
