Hey guys,
I recently sought to upgrade my late 2008 2.1 GHz Intel Core Duo Macbook from 1 GB of memory to 4 GB. I'm using 2 new 2GB RAMS from Best Buy (PNY DDR2). Installed them...Macbook wont boot up (light turns on, black screen, sound doesn't occur/nothing happens). However, keeping one of the old 512 MB rams in and one of the new 2 GB rams in will work fine with total memory equalling 2.5 GB and the computer is quite faster...just have the two new ones in wont work. But, I know this Macbook is capable of 4GB total.
I did a little research and found other people having similar problems with PNY ram, but really didn't find any definitive answer. Should I return the RAM and try a different brand?
Also, for the time being, if I keep one of the new 2 GB PNY ram chips in along with one of the old 512 MB chips, should this cause my macbook any problems? (mismatched ram chips)
Thanks!
