1GB Memory for ReadyNAS NV

I wanted to upgrade my NV+ and had a LOT of trouble finding definitive information on what to buy. So I first took-apart my unit and found this:

Unigen UG032D6686LM-GJFHYN
256MB DDR400 SO-DIMM 200PIN

Then I searched (and searched, and searched some more) on 1GB SO-DIMMs with a CL of 2.5 and came-up with a grand total of one, which I found at Newegg.com:

AllComponents ACSO400X64/1024
1GB SC DDR-400
http://www.newegg.com/Product/Product.a ... 6820159414

Seeing a positive NV+ review there, and that it was only $29 bucks, made this a must-buy for me. Almost done with the 2nd test, after one successful one already--seems like a winner.

Apparently some here have been successful with other speeds (and 3.0 CAS Latency) but I am happy to find a 1GB chip that matches my old SODIMM.

I have two NV+ units. One came with 256M the other with 1G...So I opened the 1G unit to see what was installed...

MT16VDDF12864HY-335F2

According to the Micron Technology data sheet, it is a 16 chip, 2.5V DDR SDRAM, DDR FBGA, 128 x 64, 200-pin SODIM, DDR333 FBGA, 167Mhz clock, 333MT/s Data band rate, PC2700, 2.5-3-3

The nice part, it the part number says it has 16 memory components...I am trying to find another one.

Ok,it's confirmed. DDR333 is enough for running NV+.

I leave this note as future reference and potential memory upgraders:

I have two NV+ running with Radiator 4.1.8.

The first one, I was able to sucessfully update to 1GB RAM (Kingston KVR333X64SC25/1G, a type which was recommended in another post). Memory test was passed successfully more than 4 times. The unit is runing smoothly.

The other one will pass the memory test (so far 5 or 6 times). But now the unit hangs while booting. First the blue power-LED will start to flash more slowly, then more irregularly, then it will freeze - either off or on. The display shows "Booting" for hours. The unit still works fine with the 256MB RAM.

I guess it only shows what a gamble the memory upgrade is ... :shock:

Was it the same module?

How much newer is the second NV+?

You are right about memory upgrades being a gamble. I tried the 1GB module out of a 2004 HP laptop as it matched the specs. It worked great, but since I only used it as a file server without any add-ons, I noted no significant performance increase, and when I needed the laptop back, I returned the original memory module back to the NV+ and the 1GB back to the laptop. That was over a year ago now.

I found a small increase in Read/Write speed with PC-router-ReadyNAS NV+ by upgrading to Crucial 1Gb memory, as documented on a little wiki that I wrote: <http://readynas.pbworks.com/>

And I found one online, installed it and it booted nicely...running tests now.
