I ran Rember memtest to test my recently-purchased 8GB Corsair RAM for Macbook Pro, and it came up with errors 2 out of 3 times.
I ran the following tests:
1 Loop: no error
3 Loops: error
4 Loops: error
I did get the feeling lately that my MBP felt slightly sluggish at times, so this error sort of confirms that it could be due to bad RAM? Or am I wrong? I would appreciate if someone could help me interpret the logs below:
