Hi guys,   I have a WRT54GL v1.1 running Tomato 1.21 and want to attempt a ram mod to increase my connections potential.   I would be happy with a 32mb upgrade but guess 64mb would be even better.
I've read another thread on this board and conclude that I should get either of the following 3 chips

Hynix  HY5DU56822DT-D43
Nanya  NT5DS32M16BS-5T
Micron MT46V32M16TG-6T

My questions are:
1) Are the above chips correct?
2) once I solder the chip to the board, it will read 32mb.  Do I telnet connect, then input the following commands to detect the full 64mb or is there more commands?

nvram set sdram_ncdl=0x000000
nvram commit

3) Once I get the ram upgraded, are the settings written to ROM or do I need to commit the new commands evertime I clear NVRAM for Tomato upgrades?

Thanks in advance for your help.
