Welcome to Tom's!
Compatible to the socket does NOT mean that CPUs are interchangeable. There are other factors involved, including cooling and power issues, not to mention that the BIOS has to support the new CPU. You would need to check with Toshiba. As far as memory is concerned, laptops tend to be VERY picky when it comes to upgrading ram. You can't just grab the first memory with similar specs. Again, Toshiba would be the most reliable source for this information.
Good Luck!

That depends on the socket of the motherboard. If it's BGA, then the CPU is soldered in and cannot be upgraded. If it's PGA, then you theoretically upgrade it with a same powered (35 watt TDP) processor.

The laptop supports DDR3 RAM. DDR3L RAM is low voltage and may not be compatible with your system. Any of the following RAM kits (save the Corsair Mac) should work fine for you.
