I've just got a ThinkPad x230t. I have this memory kit from Crucial that I've got for a different Laptop. Note that they are both DDR3. The problem is that this memory kit does not work with my x230t. When I sent a ticket to Crucial, they said that nothing in their website mentions that they are compatible. Does anyone know why they wouldn't be so?
It looks like the issue with CT2CP51264BC1067 and the ThinkPad x230t would be the speed of the RAM. The ThinkPad x230t requires 1600mhz or 1866mhz RAM. The kit that you had purchased is 1067mhz. Usually, the RAM would just run at the slower speed but it can cause other issues in some cases. Please let me know if you have any other questions about this system.
