Laptop RAM

Well, there is one shop u can try, its called, Java something, its not a jave center, just a name, but the guy in there is one of a kind, if anyone knows to get these in Qatar, he will. It's in Al-Azizyah Area, if u know Al-Azizyah complex, there is this big large shops street behind it, its there, sorry, lost its contact info, u can pay him a visit. and u can always order them online from whatever company ur buying from, or just look them up on ebay or something, Never tried on small stuff like that, but give it a try, hope I helped :)

@MagicDragon, my laptop is HP, I bought it a year and half ago, and its 1*4gb ram, my fathers, he bought it three months ago from germany, 6gbs + 2 free slots (laptop)

and besides, I think baldrick2dogs is asking about computer ram chips, not laptops, was just making things clear, no hard feelings :D

Which type of RAM, which clock frequency? which laptop can manage more than 3 GB?

I am not (100%) sure but you could try at Al Massa Computer on Salwa Road next to Sedarat Iran Bank.

Hope it helps!
