As more people ask me to update their WRT54GLs I'm getting a handfull of original Hynix RAM chips (the 16MB ones).

Are they of any value for the WRT54Gv5 users?
Is it possible to use them there?
(I s ...

I got the MT46V32M16-5B chip from a Kingston KVR400X64SC3A/256 SoDIMM DDR module.

I believe - any four-chip module will do.

If you do not have any industial-grade soldering station - follow [url=htt ...

Yes, right, on the very first power-up an unmodified NVRAM and MT46V32M16 will give you 32MB only.

Editing the NVRAM as shown above and power-cycling the box again will give you the whole 64MB of RAM ...

Both v1.0 and v1.1 (supposedly - WRT54G v2.0~4.0 too) can be upgraded with the Micron's MT46V32M16 chip.

Without any further messing you'll have 32MB.

After doing
nvram set sdram_init = 0x0113

I've just soldered the MT46V32M16 and only 32MB are available...
Isn't MT46V32M16 a DDR SDRAM chip?
Sorry, probably I do not understand your question.

My WRT54GL v1.0 works fine with the MT46V32M16 c ...

sdram_refresh=0x0000
sdram_ncdl=0xfd0009

the same here with WRT54GS, WRT54GL and buffalo WHR-HP-G54
My WRT54GL v1.0 with OpenWRT RC6 works fine with WPA2-Enterprize: I am able to control the SSID broadcasts properly.

Go forth and debrick!!

No, I'm not debricking it (yet), I'm going to replace the FLASH chip now.
(BTW, the RAM upgrade was half-successfull: from the 64MB expected I see only 32MB available...)

There are no RH2, RH3, RH4, RH5, RH7, RG1 resistors soldered close to the connector placeholder.
Only the RH8 is there (4k7).

Do I need to solder them to be able to use JTAG?

I have just replaced the original Hynix HY5DU281622ET-J chip with the Micron's 46V32M16-5B F (the smallest SDRAM I could find).

I expected to be having the full 64MB, but instead I have only half of ...
