What is the acceptable RAM model for T400 2764 CTO (I mean ram BUS number)?

[sarah-kho]

Hi,

I have T400 with the model number 2764 CTO. It has 2*2 GB of ram installed and now I want to add a 4 GB module and remove a 2 GB one.

The problem is that I have the option to get a BUS 1066 mhz or BUS 1333 mhz RAM and I do not know which model will work with my laptop.

Please let me know if you happen to know whether the 1333 works on the laptop or not.

Thanks,

Sarah.

both 1066 mhz and 1333 mhz would work, but they all operate at 1066 mhz speed. That is the speed at which they operate at. I think you should just get the 1066 mhz version.
