I have a SR MBP (see sig). I recently purchased a 4GB kit of OCZ ram from Newegg. In the few days following installing it, I had a couple kernel panics so I ran memtest. It turned up numerous errors. I reseated twice with no change. The original Apple memory had no errors. I returned the memory and purchased the 4GB kit from OWC which arrived today. It is Techworks branded (although I only ordered their house brand). The first thing I did was run memtest and in the first run it started turning up numerous errors so I aborted and reseated the ram. I then successfully ran memtest (3 runs) with no errors. OS X appears to run fine but I really haven't used it much yet. So what do you guys think? Should I do more testing? Am I good to go? I'm still a little concerned that I got errors the first time even with new ram. Could there be some inherent problem with my MBP? Thanks for the advice.
