Performance ram for a lappy is kind of hard to find.
If you are not increasing the amount of ram you have, save your money. You wont see much improvement by going to a slightly better ram if your staying at the same amount.
If you increasing your ram amount I would say buy some quality ram, and possibly do some tweaking on it in the BIOS, if you can.
