Q: MacBook Pro - RAM Upgrade Problems
I recently purchased the Kingston 4gb RAM upgrade kit for my MacBook Pro. The RAM is the KTA-MB667K2/4G model with 2 x 2gb memory modules. According the Kingston website this RAM is compatible with my MacBook Pro (details below).
When I inserted both new moduless, my MBP failed to boot. The power light illuminated but OS X did not boot. I then tried the following permutations:
1. New 2gb Kingston module + the original 1gb Samsung module = booted and recognized a total of 3gb RAM.
2. The second 2gb Kingston module + the original 1gb Samsung module = booted and recognized a total of 3gb RAM.
3. Either of the new 2gb Kingston modules ALONE = MBP did not boot.
4. I inserted the both 2gb Kingston module into a MacBook (white, 2008 model) and the MB booted and recognized the full 4gb memory.
The experiment suggests that the memory modules are OK. I should also add that all permutations were examined when testing the Kingston memory modules in the MBP i.e the RAM bays were fitted to both modules during the tests.
There are similar reports of MBP not booting using this type of Kingston memory. Any help would be appreciated.
