RAM upgrade for wl-500gx

[Ivan]

well
If I find IC K4S561632E-TC75, I can try it.

I hope...

512Mbit chips have 66 pins. It's difficult.

512Mbit chips have 66 pins. It's difficult.

Not the ones I had in mind....

Edit: digikey has them in stock: http://www.digikey.com/scripts/dksea...MICRON&site=us

[Ivan]

eh eh do you have try debian with 64Mb?

[CountZero]

Too expensive for me But digikey was cheaper.. if it weren't for shipping and import duties... well well 64MB is enough for now

No, and I don't plan to, 128MB would be helpful for debian I think..

I am quite happy with Olegs firmware for the moment. I have tested transmission without any swap and it seems to run fine. Still have to do some more testing with more active torrents(max 2 so far) but I don't have a suitable HDD(i.e a silent one).

[Ivan]

on my WL500G Deluxe I have Olegs firmware + debian and... AMULE
It work correctly but if I put more 6 files to download, swap wake up to 30Mb and cpu usage is too expansive.
swap file on HDD is too late...

I've 80Gb HDD 2.5" attacked to USB port.

perhaps with 64Mb it work perfectly.

[CountZero]

I have a 3.5" HDD, but keep it switched off for most of the time... next time I get one with automatic spindown

Next thing on my list is a quiet 2.5" hdd (but one of the 1.8" would be nice )

Main motivation for doing the mod was to see if it was possible and perhaps download torrents while away(possible anyway)... I'm not realy a software guy.. more interested in hardware

If you do upgrade, practice on something cheaper first until you feel you can do the soldering without damage to the router.. like an old motherboard, find a suitable chip, remove it and put it back... hopefully it will work as before (but do check that it worked in the first place )

Thanks
However, you have buy and mount MT48LC16M16A2P-75: D from micron, confirm?

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.

[Tamadite]

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.

First deluxe is upgraded to 64MB!

First test was not good, there was no output on serial port. I looked again, and there was one tiny connection between 2 pins.

That did the trick!

Router booted normally, with 64MB reported!

              total         used         free       shared      buffers
  Mem:        62968        10096        52872            0         1208
 Swap:            0            0            0
Total:        62968        10096        52872

Great! Another 2 deluxe's to go!

First I will run this one for a while, to see if it will be stable.

I used Corsair SDram 128MB PC133 module, 4 chip on one side.

I'm selling my wl500gx routers, because I'm migrating to other hardware. But I have still some memory chips messing around here, which will fit for the Deluxe router! So, if you're interested in them, send me a message. I can also do the upgrade for other people, my deluxe is running fine until now on 64MB.

If you want me to do the upgrade, send me a message.
