How many of the tests did Memtest86 get through in an hour? Even though the early tests may be passed with no errors the latter ones might show up errors. To be sure you can run it using the extended/all tests option (to found under "Test Selection"), although it is time consuming.
Also be aware that if Memtest86 finds errors, they could be actually caused by your CPU (or possibly your motherboard?). As Jiff Lemon mentioned, if you do get errors, then re-test each stick separately, as only one might be bust.
