    I have a MBP 2009 13’’ but one of the RAM slot is out of order.

    Could I stick in one single stick of 8GB RAM in the slot that’s working, or would it only take up to 4GB RAM stick?

    I think in the Core 2 Duo era regular motherboard RAM slots were only made to work with up to 4 GB per module.

    Core 2 platform can support 16GB, however it was up to OEMs to enable it for higher density memory.
    You could try a stick of 8GB in the 2009 if you're running Lion or higher as Apple enabled support for the 2010 model which uses the same memory controller, keep in mind once you cross past the 8GB mark booting back to a Snow Leopard can't be done. I'm guessing Apple held out 16GB support for a native 64-bit OS due to kernel limitations of SL.

    I own a 2010 13" MBP, did it just to see what would happen and being unable to dual-boot Snow Leopard(for Rosetta) left me downgrading.

    Can anyone confirm this? One slot can hold 8GB for 2009 as long as you are running Lion or higher?
