12gb of RAM. Is it a good idea?

Solution


Who told you that??? Of course you can. Some people say you shouldn't, but thats another issues. I've used different sized ram sticks in the past and had no issue. Again, forget whether you should or not, don't give false info saying can't use them because that is false.


One more thing lets say that 8gb stick is dealing with game. Can 4gb stick afford web browser in the same time?

RAM doesn't work like that.
It is all one pile.

8 + 4 might work, but no guarantee. It is highly advisable to have a set of RAM, rather than 2 random sticks in there.
 


What the guy told you is false you can use 8 and 4 gig sticks together. Also no you can't set one stick or ram to be be set aside for one task and the other stick for another task. You have pool of ram and it is all available for any job that needs it.
 


I guess that only memory speed shuld match up right?

 


Even that is not a must. They will run at the speed of the slowest stick. Again, you should just have the same ram, but different capacities and speeds wont stop the computer from working in most circumstances.
 
Sure you can. I have 2 different sticks in my laptop. Came with 4; I added 8 to it. 100% stable. Not even the same manufactuer.

It will match timings to the slower of the 2 RAM sticks, but it's generally a good idea to try to match latency and timings between sticks so you're not degrading the performance of a faster stick.
