Hi, so I have Sony Vaio VPCEB4JOE laptop. I'm just wondering if I should upgrade to ddr3l 4GB 1333MHz or 1600MHz? My laptop has built-in 3 GB (1 - 1 GB and 1 - 2 GB).
UPDATE: I have now upgraded to 2x4GB ddr3 1333 MHz and it was a success! Now when I click my start menu, it opens right away! Thank you everyone for the recommendations, appreciate you all!
