M9750 + MemTest -- OMGL!

Ok so I thought I was super hardware guy ( LOL ) until my laptop gave me a run for my money... After seeing some performance issues ( especially in Aion ) I decided to benchmark the box yesterday with MemTest 2.0+ ( Came with CloneZilla ) ..... After taking down some results I'm confused as to some of the findings.. Maybe some of you uber hardware guys out there can decypher it for me. For testing purposes I put 1 2GB stick in each slot and then ran MemTest for 1 pass ... lastly I put back both 2GB sticks in the slots and ran that ... below are the results....

As you can see things are pretty much the same except when the RAM is in DIMM2, then the Type is changed to DDR-II and the CAS settings are more... I'm just courious as to see if anyone else has the same type of benchmarking or if I should go out and purchase some better RAM? .... Sorry for the long post...
