On WL-500g leg no. 36 (SD_A12) on memory chip is not connected hence memory upgrade is not possible.
Does somebody know if there is some guarantee this is to work on a WL-500g?
I have taken a look at the schematics of the WL-500GX but I do not find the R68&R69 connected in the same manner in the WL-500G. I do not get continuity between R68&R69 and leg 36.
On WL-500g leg no. 36 (SD_A12) on memory chip is not connected hence memory upgrade is not possible.
I'm definitely interested in this upgrade. It looks like this module would do the trick for 2 128 MB upgrades. What say ye?

I like the idea of buying new chips from Digikey because then you don't have to desolder, but I am pretty good at desoldering, and considering the price difference, the Kingston module seems good.
Looks OK. Go for IT. Post results.
Hi Guys,
Now I'm using competitive firmware DD-WRT,
but I tried to upgrade WL-500gp to 128MB RAM according to post http://wl500g.info/showthread.php?t=...ighlight=hynix
I need more RAM to run asterisk. Now I'm using Torrent client and FTP server with USB disk.
Unfortunately upgrade failed. Slowly I'm induce to Oleg's firmware, but decision like this required time to configure router once again and familiarize with new firmware.
I'm not a linux specialist, so this is not easy for me.
This is quote from DD-WRT forum, but nobody can help me. Maybe somebody of you give me answer.
[QUOTE]I'm tried failed RAM upgrade (to 128 MB) on the WL-500gp. It was done by follow post from Oleg's forum:
[URL="http://wl500g.info/showthread.php?t=7048&highlight=hynix (is written in russian language, but I know it a little). Before replacing memory chip from 2x HY5DU281622ETP-5 to 2x HY5DU121622CTP-J, (which should give me 128 MB) I sets NVRAM settings (only 16 MB):
nvram set sdram_init=0x000b
nvram set sdram_config=0x0032
nvram set sdram_ncdl=0
nvram commit
Desoldering and resoldering was not so easy (I haven't experience with hot air station).
Finally router doesn't want boot correctly. Power led came on, but router don't respond on ping. So I replace memory chips once again for new one (maybe damaged ? over temperature ?), without new result, and again new chip and again the same. It was possible to put router in firmware restoration state (by pressing together restoration switch with power on), power led start flashing, but putting firware was not possible.
My questions is:
DD-WRT can support 128 MB RAM ?
How works memory detectiom at startup ? Only by NVRAM settings ? CFE ?
Generally what was wrong ?
I came back to old one memory chips, work fine.
sorry for my english[/QUOTE]
Which setting I have to set before upgrade ?
Problem was with firmware or not ?
regards Gidus
So, I understand my mistake. Problem probably was with NVRAM settings.
Module HY5DU121622CTP-J is a DDR333, works only with CL2 or CL2.5
I try to understand rules for set correct nvram variable settings sdram_config,sdram_init http://wl500g.dyndns.org/sdram.html
but could you help me and suggest correct one for
HY5DU121622CTP-J ? http://www.hynix.com/datasheet/pdf/d...TP(Rev1.5).pdf
regards Gidus
Have anyone did it success , Pls tell the step in eng.
Thank you very much..
Has anyone can tell step for wl500gp.
Can anyone translate this thread or provide step by step guide?

Would it be nice to have 128Mb of ram for wl500gp
use babelfish it to translate

typically, what are the tools that u will need to do these stuff? .. that is, adding more RAM. from what i gather, we must have excellent de-soldering and soldering skills to do so?
are there multiple methods to do it? where can I find tutorials on how to solder on new RAMs?
lastly, i do not understand.. what is the issue that is limiting us from adding alot of memory? why can't the router detect properly / function as it should if the RAM used is too large?
Oleo, I have a deluxe for testing, and a 4 chip 128MB PC100 sdram package. So, I'm ready for the upgrade, but is there a reason for PC133 instead of PC100?
In your tutorial, you say that 128mb is the maximum possible configuration. If I find a 4 chip 256MB module, will it bring me 128MB when I use your tutorial?

PC133 means 60ns while PC100 means 70ns RAM speed. If you look at schematics you'll see -6 RAM is specified. I could not tell you if PC100 will work, but I assume that it should. If you look at http://wl500g.dyndns.org/sdram.html you will see that there is cas_latency whch is calibrated during boot if sdram_ncdl is reset. So there is a chance that PC100 should work.
With 256MB 4chip module you could have 128MB router. Oleg reported success on Premium, while I've read that Deluxe had problems with 128MB.
