    I'll be purchasing a T61 soon, which has "PC2-5300 SDRAM DDR2 667MHz SODIMM" type of ram installed.

    1) I'm assuming if I purchase more ram elsewhere that is of this same type, it should be compatible, yes?

    2) How does the Pin # number factor into this? Should I care if it's 200-pin or 240 pin, etc?

    3) Kingston sells "system specific" memory. Apparently this RAM that is specifically designed for certain computer models. Is this what Lenovo puts in their machines, and is that why upgrading RAM from Lenovo is more expensive? Or is it just because of the labor costs? Should I try to buy ram that is "system specific"?

    1.) Yes

    2.) Yes it does. If you have ram with the wrong number of pins, it will not fit into the DIMM slot.

    3.) It is often cheaper to buy RAM from places such as newEgg, instead of system specific RAM for Kingson or Crucial. Simply make a note of the RAM details using the Kingston RAM search function and search for the RAM elsewhere. RAM would be much more expensive if you buy from Lenovo.

    2. 200pin is pin# used in notebook memory. Only some ultraportables have different pin count memory. But by and large almost all laptops use 200pin DDR2(DDR if you have an older system) SODIMM's. 240 pins are typically used in desktops with DDR2 slots.

    3. They just gurantee that the memory will be compatible with the system but as lil mayz mentioned you should be fine with buying cheaper memory elsewhere.

    Frys.com is also a great place to load up on memory.
