Thank you very much for the info.
I asked HP and they answered me this: "The memory used in the customized HP Pavilion dv4000 series is 333 MHz DDR SDRAM PC2700"
We all know that is not true, not for the current model, so WTF is wrong with those guys that are supposed to give us technical support???
I still can't decide:
-2x512=1GB for $150 from HPshopping.com
-1GB from newegg.com + 512 (free upgrade form 256 to 512) from HP = 1.5GB for $88
The 256MB DDR2 PC4300 module and the 1GB DDR2 PC4200 module are compatible, right??? But will the memory run on Dual Channel??? Or both modules have to be the same to enable Dual CHannel???
Billcsho: I hope you post some information about your experiences with the memory upgrade.
