Lenovo Thinkpad T430



Works good with Gentoo. Following settings aim to make Thinkpad T430 usable.

RAM


ThinkPad T430 supports up to 16 GB of SO-DIMM DDR3/DDR3L memory. Max frequency that you can buy is 2133 MHz. DDR3L is better because it is 1.35V instead of 1.5V so it stips 10 percent less battery with the same performance as DDR3. To check how much of memory the laptop has:

This shows one 4GB module is installed and a second is unpopulated but available.

To find out the frequency of installed RAM modulesː

If you install second RAM module - note that they must operate on the same frequency, but size can differ (for example 4 GB plus 8 GB).
