HI Everyone, In order to boost performance of my DUO v1 with respect to add-ons, I wanted to upgrade my stock 256mb memory chip to 1GB. I have read Netgears's official stance on upgrading RAM (i.e. don't do it and if you do, support will be denied) and read a number of posts in this forum related to what people have gotten to work. I also realize I will not see a speed improvement related to data access. Merely a potential improvement when it comes add-ons. Does anyone know where I might purchase a 1GB memory module (or even 512 MB) that is highly likely to be compatible with my Duo V1?Maybe some here knows were I can obtain an older module, who someone who just purchased a newer one a few months ago that they know works for them.Alternatively if anyone here as a 1GB memory module that they were using reliably on their Duo v1 which they no longer need I would be willing to buy it off of you.-Brad

If I remember correctly (from my Duo which I upgraded to 1GB), there were an issue, with memory timings.CL2,5-3-3-7 DDR400 SODIMM from PQI was the only one which worked for me. Actually DUO memory runs slower than 400Mhz (DUO has 333Mhz Bus), but I discovered that its pretty explict on timings.With "high-performance" CL2-2-2-5 DDR400 Memory it didnt even boot, regardless of the fact that memory modules are definitely capable of running on more "loose" timings.As old DDR memory modules arent actually manufactured anymore, you may run into problems finding one... :roll: (I had to buy my PQI stick from aftermarket, and this was already 2 years ago)

Hi Etz, Thanks for the information. I don't suppose you no longer need your 1 GB CL2-2-2-5 DDR400 memory module by any chance? I'd be willing to buy it off your hands since you know it works.--Brad

I dont have that anymore, as I sold it with my Duo... :roll:And that other CL2-2-2-5 SODIMM is in use unfortunately...also it didnt work with Duo... :)

I've just confirmed a brand new Crosair VS1GSDS333 for my ReadyNAS Duo v1.Works like a charm, but as expected no fancy speed upgrade, bottlenecked by CPU.Exact type for reference:

Also just installed a Corsair VS1GSDS333 for my ReadyNAS Duo v1 (went from 512Mb to 1 Gb). Ran the memory test 2 times, both successful, booted and everything looks okay. The Squeezebox Server responds noticeably faster (still not screaming fast) which was my goal. No other noticeable improvements.

Duo V1 Memory Upgrade : Recommended module at this time?

FYI, I just installed this memory (which you can still buy in several webshops in the Netherlands) in my Duo and it seems to be working fine.

Just installed the Corsair VS1GSDS333 memory module and I am running through the first time through the memory test now. Last night I ran through the memory on the existing 256 mb module just to make sure I understood how to start the test and read the results. Thanks to Afiorai for his post on translating the LED sequence from the 4 bay NV to the two bay Duo (since the duo only has two drive LEDs).

I'll let know how well the Corsair works for me.

Incidentally, The factory installed memory module was an Apacer SOD PC3200 CL3.(P/N 75.85387.G00)

Well it looks like a no go for my new Corsair VS1GSDS333. Although it passed the memory test twice, when i tried to boot using the new memory module it failed to boot. I put the original 256 mb module back in and the units booted fine.

I will try once more tomorrow just in case it was a problem with seating the memory (though I would have thought that would have resulted in a failed memory test). If it does not work, I may be able to put the !GB module into our old Toshiba satellite laptop.

If tomorrow's try does not work, any other suggestions ?

Having a Duo v1 as well I'm Interested in your experiences.
But from what I've read so far, it seems to be a risky operation with unclear results.
And the performance gain seems to be minimal. So I do hesitate.
