Problem with memory upgrade
I was change memory, upgrade to 128 Mb.
Hardware testing memory was done, but linux not see this:
~ # cat /proc/meminfo | grep MemTotal
MemTotal: 61948 kB
~ # dmesg | grep Memory
Memory policy: ECC disabled, Data cache writeback
Memory: 64MB 0MB 0MB 0MB = 64MB total
Memory: 55424KB available (2466K code, 454K data, 112K init)
How know what I must change in system for use new memory size?

Re: Problem with memory upgrade
Nothing to see, I was exchange modules. 32 to 64
I use foehn, extractor and solder. Its my work I fix broken memory card. Its very easy if u work with it.
But I not work with software. Please help me? How can dns-323 recognize new memory size?

Re: Problem with memory upgrade
I read about same problem but in PC. Memory size was written in GRAB loader.
But I dont know how to exactly solve my problem. Please, help if u knows!!!

From my point of view, more ram= more loaded apps = more fun. Adding faster ram would be great too, but maybe it's technically impossible.

Re: Problem with memory upgrade
I don't think you'd need to do anything to tell Linux that there's more memory, it should use whatever the system says it has... perhaps the problem is something to do with the DNS-323's bios?

Re: Problem with memory upgrade
Hurray! I've successfully upgraded my DNS-323 to 128MB RAM.
I'll start a thread in the custom firmware discussion on details as the steps are not trivial and risk of trashing your DNS-323 (either physically or software bricking) are high.
In short it requires upgrading the RAM modules to 64 MB versions of the right specs as Alexman did + patching U-Boot (which has hardcoded settings for memory on the DNS-323 rather than any dynamic discovery mechanism).
Why do it? #1 to see if I could and #2 I want to run SqueezeCenter 7 and hear that it really likes more RAM.

Re: Problem with memory upgrade
Congrats to JDOERING!!! I've thought about this one as well. Have you done any benchmarking to see if there has been any improvements in transfer speed?
Cheers!

Excellent, and let us know if and how you got squeezecenter to run. If you manage that I'll take the risk and upgrade as well.

Re: Problem with memory upgrade
Is it possible via the same proccedure to go for 256 mb? This makes the nas more future proof.

Re: Problem with memory upgrade
No; I don't think 256MB is possible. Most importantly I don't believe any source of 64Mx16 DDR1 chips is available. All the chips I ever located in that density were DDR2. While the Marvel chip can handle DDR2 - they are all BGA instead of TSOP by design so they can't be mounted on the DNS-323 board.
Even if 64Mx16 DDR1 chips were available; I'm not sure that the U-BOOT memory settings allow for that - although they very well might.
If anyone knows of a source for such chips; let me know.
I know that piggybacking of chips was used on the NSLU2 to add more chips than motherboard pads but (1) that required knowing pinout of other memory controller pins to connect to (2) the NSLU2 uses slower memory and I've seen suggestions that this DDR1 memory would be sensitive to intereference issues if piggybacked (this question was raised about the Asus WL500gp) and (3) I don't know nearly enough to sort out those details.
I'm working on SqueezeCenter 7.0.1 now...
