Guys I'm new to this forum, please bear with me. I ran memtest for one hour and got 0 errors, then I ran it for another hour the next day and got 6 errors. The next day I run it for 5 hours and get 0 errors. I dont know wheter the the ram is faulty or whether the 6 errors were flukes. Next question: On my other computer whenever I put in any ram into it, I always get an error before windows boots up saying "memory read failure" with a lone number. When i take the stick out it boots up fine, but this happens will all sticks that I've tried so far.
