Q: Hello, i have an imac 21'5" late 2009 with 4GB ram...with Mavericks its becoming slower.

So I'm thinking to upgrade my Ram from 4GB (now 2 slots with 2GB) to 8 gb.

Is it Ok if I put one modeule from 4GB INTO MY THIRD empty slot ? Or do I have to use 2 times 2GB like in the other slots ?

 

Thx

iMac, OS X Mavericks (10.9.1)
