I purchases a new laptop from ASUS, which come with 256mb of ddr-ram. I checked the ram, it's code = HY5DU561622DT-J. from Hynix. And i checked it on internet, my model of Ram is ddr 333, x16 66 pin. And i would like to upgrade my ram to 512 Mb, can i buy a ram which is also ddr 333, 66 pin, from other brand, such as kingston, and add it on my laptop? Will it stack with the elder one? coz i has a friend, he add 256mb ram on his own and he still get 256mb.
 
but then.....i can't find a kingston ram with 66pins? SO DIMM always come with 184 pin or 200 pin? and i check it on the lynix site, the ram is isn't a SO DIMM ram, it is a DDR ram.
 
172 pin? I only saw 66, 72, 144, 184, 200 pin memory so far. And, my laptop support dual-channel DDR. So, if i install a 200 pin DDR-333, would it run at dual-channel? I m just worried that, even i install 256mb ram more, and it won't give me any increasement. As i said, my friend laptop come with 256, he add another 256, but in the info still give him 256ram
 
My guide on laptop RAM was Newegg.com, and they had 4 kinds listed (for notebooks and laptops). Generally, I've found, if it's out there Newegg will have it listed. I don't know how they'd manage to not carry an entire slot-type of RAM, much less 2-4 slot types.....I've not previously dealt with laptop RAM stuff, but at a glance something seems fishy about the 66-pin bit.....Anyone who knows a bit more than me about laptop RAM is encouraged to step in and help, because, though I'm resourceful, I'm confused, and I'm a bit curious as to this whole pin differentialization bit.

EDIT: I did a Google search, and can now say with total confidence; There is no such thing as 66-pin laptop RAM. Either you got a bogus reading, or you read it wrong. Try using a different program, such as CPU-Z or AIDA32.

The "66-pin" bit on that webpage is in reference to the TSOP modules (which I'm assuming are the physical chips on the sides of the RAM). It isn't 66-pin RAM. I suggest using AIDA32 or CPU-Z; they're easy to use, and they'll tell you how many pins the RAM has.
