WL-520GU RAM upgrade

[itanium]

Greetings, e'body...
I'm new to this forum
I have Asus WL520GU, and don't know if this is the right thread to talk about upgrading RAM on Asus WL520GU.
Currently have experience with tomato, optware, and USB flashdisk/HDD on it.

The Asus WL520GU has 4MB Flash, and 16MB of RAM.
Is it possible to do 32MB RAM upgrade or 64MB to asus WL520GU?
I see pin 36 (A12?) is disconnected by R66 which is not there.
Is it simply replacing the memory with a 256Mbit or 512Mbit chip?
What is the setting for the nvram sdram_init?

Hi,

I'm planning to upgrade RAM in Asus WL-520GU router. There is only one memory chip (actually Samsung K4S281632I-UC60 8Mx16). If I use 32Mx16 SDRAM chip (ex. Samsung K4S511632D-UC75) will I get 64MB of RAM or only 32MB? A12 line (actually not connected) should be connected?

What's a good 128MB SDRAM for WL500g or WL-520GU?

Thx, Ivan
