    Some machines (PC And Mac) have issues when downclocking large amounts of RAM. Return the 2x4 GB sticks of 1333 and go with 2x4 GB sticks of 1066 and it should run nicely.

    I also recommend you reinstall the old RAM and update to the latest firmware first.

    It would come through Software Update.

    I just had a similar experience with my son's late-2008 MacBook. i upgraded his original 2 GB of 1066 RAM to 8 GB of 1333 RAM. It restarted normally and recognized all 8 GB in the system profiler. But he started getting system and app crashes. Once I put the original 2 GB of factory RAM back in the stability returned to normal. Slower, but no more Safari or OS crashes.

    I ordered a 4 GB upgrade kit of the proper speed RAM from Crucial.com and he'll just have to live with that. I might upgrade his hard drive to a 240 GB OWC Mercury SSD though. :D

    I don't think it is an issue with the downclocking when you are at the RAM limit rather than hitting the limit. I have used many 8 GB RAM equipped machines but it only had 1066 MHz RAM.

    I'm pretty sure that all Mac-RAM sellers do is buying OEM 1066 RAM from China, apply a brand adhesive on the modules and test them before selling. And this process adds from 500% to 1000% over the original module price.

    We just needed knowing their suppliers to buy inexpensive RAM.

    The importance is to buy the appropriate speed and capacity RAM.

    In summary, 8 GB is fine, but it must be the correct clock speed. Many different computers I have worked on have issues downclocking RAM when it is to the limit.
