First time upgrading RAM for a laptop,SODIMM or SDRAM?

[cracker2]

Cpu is a T2330 533mhz.Need a 2x1GB kit.
I am a bit confused.On my laptop specs it shows,
1024 MB 667 MHz DDR2 SDRAM (2 × 512).http://supcontent.gateway.com/s/Mobile/2007/Tempest/2905980R/2905980Rsp2.shtml

But when looking around for the hynix models ram in my laptop it says,
Hynix: HYMP564S64EP6-Y5 DDR2-SODIMM
https://support.gateway.com/s/Mobile/Q106/Oasis/2523232R/2523232Rsp8.shtml

I would like to know which is it?Also would like to know how to find the fastest I can get overall.

Here are the ones I am looking at.
Kingston HyperX 2GB (2 x 1GB) 200-Pin DDR2 SO-DIMM DDR2 800 (PC2 6400),timing:5-5-5-18

Kingston HyperX 2GB (2 x 1GB) 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300),timing:4-4-4-12
http://www.newegg.com/Product/Product.aspx?Item=N82E16820134660

G.SKILL 2GB (2 x 1GB) 200-Pin DDR2 SO-DIMM DDR2 533 (PC2 4200),timing:4-4-4-12
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231118

Anyone know where I can find this?
DDR2 SDRAM: DDR2-1066
Data rate:1066 MT/s 
Bit time:0.95 ns
Command rate:533 MHz
Cycle time:1.9 ns

pc2-5300 is the same as ddr2-667. According to gateway, 667 is the fastest it supports. So you would need any of these.

Thanks john!I wanted to make sure I got compatible ram.Would you go with the kingston or G.skill?Its just a $9 differance & they have same timing.Im not good at brands for ram.

On a laptop with only max ram of 2gb, you won't notice the difference in the timings. Therefore I would just suggest getting one of these.
