I was wondering. since i cant get any information off the internet about this model.

I am planning to change the stock rams to either corsair or hyperx rams.

I know that this laptop is so far said to only be able to hold on max 4gigs of ram, which im very dissapointed.

Can anyone suggest, or maybe specifically recomend me the model of ram which i can change to.

BTW, i want ddr3 rams, high performance if available, and of course has to be available in malaysia.

Ive tried certain webs about ram checkin but it seems that this laptop is too new for them.... so no databases

Compaq has bad support on performance ram. Value ram with normal latency is fine though. 
So, NO to you for performance ram like HyperX

i see. so can i use this??? Kingston DDR3 PC1066 Notebook 2GB RAM - RM 180. its normal rite??
