the Notch. google notch position for ram types.

Yours is a PC3-10600 . Means DDR3 Ram with 1333mhz clock.

Memory Clock : 166(2/3)
Cycles : 6 ns
I/O bus clock : 666 Mhz.
Data Rate : 1333 Mt/s.
Highest transfer rate : 10666MB/s

So which ram should i buy the one with bus clock 666Mhz.??

if you have only a single stick of DDR3 1GB, replace it with a single stick of DDR3 1333Mhz 4GB.
