Well personally I think there is something very wrong with your machine if it takes that long for 4 passes it really shouldn't take more than overnight say eight to ten hours.
There is no tester machine that I know of maybe some store techie might do now what I might suggest is to run the test on one stick in slot 1 if it passes then do stick 2 then stick 3 etc that way if you get no errors at least it means that the sticks are ok likewise if you do get errors you will likely have found the culprit stick.
Sorry mate there is no other way.
