Will this work in my 21.5 iMac late 2009?  Apple says PC3-10600 1333 DDR3 204-pin SO-DIMM.

Accepted Answer

I'm not familiar with mac but if all the numbers/specs match I would think so. hope that helps

Question 2

Does this memory compatible with Asus G53jw-nx1? Thanks

Accepted Answer

Bought mine for an Asus G73 (iirc) that I have since sold. I believe it should work for yours as well.

Only stipulations for your model as listed with Asus are "DDR3 1333 MHz SDRAM, 4 x SO-DIMM socket for expansion up to 16 G SDRAM (Quad Core), 2 x SO-DIMM socket for expansion up to 8 G SDRAM (Dual Core)"

If yours is anything like mine, there is one memory card that is nearly impossible for consumers to replace. If you are having memory issues best to run memtest to determine which module is causing it. if just looking to expand, use the specs on the existing ram as pairs need to match up (i.e. socket 1 and 3 need to be the same and 2 and 4 need to match) good luck!
