I have an ACER aspire 5733. It came with both memory slots filled, one DIMM0 with a Kingston DDR3 1024mb PC3-10700 (667 MHz) and the other, DIMM1 with a Kingston DDR3 4096 MBytes PC3-10700 (667 MHz).
I'd like to replace the smaller one with another 4gb stick so that it performs a little better, and is more likely to cope with Windows 10, but I can't work out how to idenitfy the right one to buy.
Which specification is most important to match. Is the Mhz important ? Some UK sites don't quote a mhz number on what seem to be the right sticks. how do I work out what pin I need?
any help most welcome
