Hey guys,
New here and got a MBP, late 2011. I upgraded my RAM from 2GB to 8GB (2x4GB). I ran Rember when I first got them, 4 months ago or so, and it passed 255 tests. I just retested them and they wont pass a single test.
I am wondering if the memory went bad, is it still good to use, could it have caused any harm to my computer within that timeframe?
