Hi,
I hope somebody knows what's going on here. I have purchased two 4GB ram modules to upgrade my MBP from 2GB.
I have installed the two 4gig ram and everything seems fine but read on the net that it's the best to test your new rams so I've ran Rember which gave me errors as follows:

So I have run Memtest86 (booting from a CD) and it also shows several errors (which I have no logs from) so I have removed one of the ram and re-run both tests. It passed both tests with flying colors so I have swapped the rams and ran both tests on the other one too. Same thing: no errors deteced.
Now I'm kinda puzzled. Should I return the rams and ask for new ones or what?
