Ok so I know it's possible to do a memory upgrade from 16MB to 32MB on the v3 series of the WRT54G routers. Will post link in a second, can't find it in the 20 or so tabs I have open right now. From what I can gather. 128M(8Mx16) - HY5DU281622ET - Stock memory module 256M(16Mx16) - HY5DU561622CT - Upgradeable chip Now my question is, can the router accept a 64MB chip, the; 512M(32Mx16) - HY5DU121622LT I looked at the pin configuration (will take a more closer look in a second) and they appear to be identical. Anyone tried upgrading there WRT54G to 64MB of RAM? I wonder if there is a 1024M chip out there, back to researching. Just wanted to get this post up, see if anyone else has tried it yet.
