Hello The reason I am asking is I bought some Corsair ram 2x4 gigs worth of ram for my laptop don't remember which type, and it is making the computer very unstable in programs that make heavy use of the ram. Have had the computer crash a few times now cause of this problem, forcing me to reboot my computer. Want to downgrade to 2x4 gigs cause I know this will be stable, just need to find the best I can get for $100 or less. The type I am looking for advice on is to what is the best possible 2x2 gigs of ram: PC2-6400 DDR2-800 240pin SDRAM SODIMM I can buy for my laptop? Was looking at: Kingston HyperX PC2-6400 4GB 2X2GB DDR2-800 CL4-4-4-12 240PIN Dual Channel Memory Kit How ever I suspect this may be the wrong type of ram and may not fit in my Hp G62-219ca laptop.
