FAQ about Lenovo ThinkPad T430 RAM
How much RAM can I put in my T430?
Max is 16GB total. You've got 2 slots, so that's 8GB per slot maximum.
What type of RAM does the T430 use?
DDR3 SODIMM - the smaller laptop memory sticks. Make sure you don't accidentally buy regular desktop RAM.
What speed RAM should I get?
1600MHz (also called PC3-12800) works best. You can use slower RAM but why bottleneck yourself.
Can I mix different RAM sizes?
Yeah you can do like 4GB + 8GB if you want. Just know that dual channel performance is better with matched pairs.
Do I need to remove the battery before upgrading?
Definitely. Unplug it, remove battery, hold power button for a few seconds to discharge any remaining power. Basic safety stuff.
Where are the RAM slots located?
Under the keyboard. You'll need to pop out the keyboard first - there's usually a couple screws on the bottom marked with keyboard symbols.
Will faster RAM like 1866MHz work?
It'll work but just run at 1600MHz anyway. The system won't use the extra speed so save your money.
