FAQ about Lenovo ThinkPad T430u RAM
How much RAM can I put in a T430u?
Maximum is 8GB total. You've got 2 slots, so that's either 2x4GB sticks or one 8GB stick if you want to leave a slot open.
What type of memory does the T430u use?
DDR3 laptop memory (SODIMM). Make sure you get the notebook kind, not desktop RAM - they're different sizes.
What speed RAM should I get for the T430u?
1600MHz (also called PC3-12800) is what you want. The system might work with faster RAM but it'll just run at 1600 anyway, so no point spending extra.
Can I mix different RAM sizes in my T430u?
Yeah, you can do like 4GB + 2GB if you want. Won't hurt anything, though matching sizes gives you dual channel which is a bit faster.
Do I need to remove the battery before upgrading RAM?
Always a good idea. Unplug it, take out the battery, then hold the power button for a few seconds to drain any leftover power. Better safe than sorry.
Is upgrading from 4GB to 8GB worth it on the T430u?
If you're running multiple programs, lots of browser tabs, or doing any photo editing - absolutely. Makes a noticeable difference in everyday use.
