Hi I have got my Linksys WRT54G v5 with DD-WRT for a very long time
but under heavy traffic, it always become unresponsive(e.g. Wi-fi down,Cant get in to info site etc.) though i have already changed the Maximum port to 1024 instead of the default 4096, TCP timeout from 3200 to 90 and UDP timeout from 120 to 90
And I have got a few question that hopefully the experts here could help me
1. The actual total Memory is constituted from two chips?
2. I have to change both with 16MByte so I can get a total of 32MByte of Total Available Memory?
3. The estimated cost for the 2 memory module is around?
4. Is it worthy to upgrade this device
Picture of the chips(one is at the center and the other one is at the right head corner with yellow labal stick on it)
Sorry for my poor english
If more information is required please tell me!!!
Thanks in advance!
First, realize that the chip front and center in the picture is the SDRAM (6ns, 166MHz, if you like specs like I do), the one with the yellow sticker is the flash memory.
So, after realizing that, there's only one chip to change to get more memory. I'd recommend replacing the SDRAM chip with a Micron MT48LC8M16A2P-6A:G ($3.63 US from Arrow before shipping.)
Like the article you were reading says, if you have no soldering experience, you should probably leave the mod to someone more experienced.
16MB should definitely stop the the freezing. I just recently moved my WRT54GS2 (8MB RAM standard) to 32MB (because it actually has pin 36 connected to the Broadcom chip.) Pics follow.
WAWO...!
Never thought that someone would still reply this old old old post! Thank You SO MUCH!
I have tried to upgrade the firmware, the situation improves a little bit.But under heavy traffic its still freeze but wifi is working.
I havent found anyone that is confident to do the soldering work, so I think I gotta halt this project for some time(till I found someone is cofident to do that)
But still, I would like to know more.
1.The chip Micron MT48LC8M16A2P-6A:G is also suitable for my WRT54G v5? Do I have to compare the number of pin and pins position again?
2.The WRT54G v5 support SDRAM that runs at a higher frequency?
3.You do the soldering work by your own? I saw quite a lot of professinal tools LOL...
I already looked up the RAM on the board and matched the MT48LC8M16A2P-6A:G's pinout and speed grade to it.
Using faster memory? I wouldn't bother trying to see if it'd make any difference or what you'd have to do to nvram settings to change that, if it can even be changed at all.
And yes, I do my own soldering I'm a hardware technician for a networking company (No, not cisco), so I have access to the fancier tools.
I saw some other brand (actually NO brand cause they are like replica) chip with model number MT48LC8M16A2P-6A:G made from china, they are pretty cheap.
Do you think its a good idea to use them or should I just bought Micron's MT48LC8M16A2P-6A:G
