MacBook Pro 2010 Mid 15" 1333Mhz 8G RAM Upgrade?

Hi all,

I had a 2nd MacBook Pro 2010 Mid 15" with i7, 4G Ram (It is a 1333Mhz, and using 1 Bank, so I still one bank RAM slot is empty right now).

I had search Google before, and look like this model work with 1066MHz only, but I am not too sure. Since new on this.

I want to buy other 4G Ram then install it to the empty slot.. But now, all 4G Ram is 1333Mhz, can't find the 1066MHz Ram anymore on 1st Market ...

Do anyone using this model who success install two 1333MHz 4G ram running on it?

I am using OS X 10.9.5 and OS X 10.10.2 with dual boot on it..

Thank you.

Best Regards,

Jimmy Chan

It work with two 1333MHz 8GB now (Two different brand RAM together)

Thank you.

It has been known to work most of the time, sometimes not. However, putting faster memory sticks in won't buy you better performance. You are limited by the clock speed of the front side bus and memory controller. You are restricted by the design the engineers originally intended the limits to be.

Match the existing stick of RAM and you should be fine.
