FAQ about Lenovo ThinkPad T400 (2767) RAM
How much RAM can I put in a T400?
Maximum is 8GB total - that means 4GB per slot since there are 2 slots. Some older docs might say 4GB max but 8GB definitely works.
What type of memory does the T400 take?
DDR3 SODIMM - the laptop-sized sticks, not the big desktop ones. Make sure it's DDR3, not DDR2 or DDR4.
What speed RAM should I get?
1066MHz (PC3-8500) is the recommended speed. You can use faster RAM like 1333MHz but it'll just run at 1066 anyway, so no point paying extra.
Can I mix different RAM sizes?
Yeah you can do like 2GB + 4GB if you want 6GB total. Just try to match speeds if possible. Dual channel works better with matched pairs though.
Do I need to remove the battery to upgrade RAM?
Yes, always remove battery and unplug power first. The RAM door is on the bottom - just one screw to access both slots.
Will any DDR3 laptop memory work?
As long as it's DDR3 SODIMM and 1066MHz or higher, should be fine. Both 1.5V and 1.35V low voltage sticks work.
