1GB Memory for ReadyNAS NV

If its an NV+ look here viewtopic.php?f=110&t=52073

NV and NV+ are practically the same as each other (differences explained in FAQ) and use the same memory as each other.

NV/NV+ be spec uses PC2700. This module will work. http://www.crucial.com/store/partspecs. ... T12864X335

If your unit came with PC3200 CL3 then this one should work as well. Not sure it will provide any advantage as I think the NV/NV+ motherboard will still be limited to PC2700 speed.

This is the stick I left in my defective NV+ that was RMA'd, trying to see if I can recover it.
NewEgg quit selling this stick, so I guess I can buy it from here, and it should work as it did in my last one.
I hope so, not happy about paying another $50!! But I want a stick that will work.

For my ReadyNAS NV+I purchased the following from offtek:

Manufacturer: NETGEAR Memory Size: 1GB Module
Product: ReadyNAS NV+ RND4450 Quantity: 1 Unit Price: £23.25

It passed the memory check, and booted and has been running happily for over a week. Which is great as when I found the memory it seemed to good to be true. I opted for the 95p first class delivery and it arrived the next day (Saturday), but I believe they also offer a free delivery service, and no I do not work for them.

Here is the URL http://www.offtek.co.uk/ram-memory/netgear/netgear-workstation-server-memory/memstid6

Now all I need to do is source some 6-32 UNC 4mm countersunk screws...

If you're in Canada (or the US) this stuff seems to be compatible:

Passed three rounds of the memory test. Full 1GB shows up in the web interface.

Sped up my NV+ a fair bit. 32-35MB/sec during large file copies. :)

I have sucessfully upgraded the memory in 2 units. one is a NV+ and the other is a Dou.

I got the SODIMM at Fry's in Houston.

Corsair VS1GDS333 they sell them for 37.99 although the will pricematch Amazon for $31.99.

Since i have seen that some people are saying the "new" corsairs, just like "new" Kingston...cruitial ... Partriat.. ect may not work, I think I have figured out what to look for in roder to make sure you get one that does....

In another thread somwhere I read that it will not support 1G-bits DDR chips. You need to make sure you get a 1GByte module made up of 512M Bit chips. The easiest way to determine this is simply to count the big chips on the board. If there is 8 that are 1M bit chips, if there are 16 they are 512m bit chips. You will likely find 8 chips on each side (front and back) for a total of 16 on the ones that are compatable.
If there are only 8 chips, it will likly NOT work. I cant confirm what wont work, but I can confirm that both the 16 Chip Corsairs I bought work.
Whats good about getting them at a B&M store is you can count the chips, and if it isnt 16....ask for a different one before you checkout.

Is that ture? Or I can just buy a DDR 333 instead of a DDR400

It will run at DDR-333 speeds. There's no advantage to buying DDR-400. (Unless it's cheaper. Then there is an advantage.)

It's the chip count that matters. Don't forget to run the memory test 2+ times to make sure it's stable.

Bought the Patriot PSD1G33316S you linked to at NCIX, installed it in a ReadyNAS NV+ that was failing to take some rsync backups. Problem fixed, rsync is now doing fine.

For the next person googling, I leave this breadcrumb from my cronjob:

my Linux server talking to a ReadyNAS NV+ wrote:
rsync: writefd_unbuffered failed to write 4 bytes: phase "unknown": Connection reset by peer rsync error: error in rsync protocol data stream (code 12) at io.c(836)

Fix that ^ with more RAM.

Consistent with randynas' note about DDR chip size, my RAM module had 16 chips on it (8 on each side).

Also I should note that if you plan to do this upgrade and perform the recommended 2 cycles of memory testing, you should budget at least 4 hours downtime for the tests to complete.

Thanks for the help, BikeHelmet, randynas et al.
