Good day everyone!I have a question about the ReadyNAS Ultra 2 memory upgrade.A couple of months ago I bought this new NAS for my home to backup, download and share files!Today I’ve upgraded the memory of this NAS from 1 GB ASint Sodimm DDR3 1066 mhz to 2GB Corsair Sodimm DDR 1333 mhz.2 Hours ago i started the memory test of this device, the pattern lit goes form1. Disk 1 lit2. Disk 2 lit3. Power button lit4. USB litI this the correct way to test my memory right, or is my memory bad?I've searched this forum but i cannot find any information about the Ultra 2 to run memory test.Thanks Alot!Bye... :shock:

I want to upgrade the memory of my Ultra 2 to 4GB. Does anyone have any experience with this?

The stock memory module in my Ultra 2 Plus was a 1GB Asint SSY3128M8-EAE1D; I replaced it with a 2GB Crucial CT25664BC1067. Works great, lasts a long time, costs only $11 from Amazon:http://www.amazon.com/dp/B001KB6Z2U/If you can't get that particular module for some reason, here are the important things to look for. Your module must meet all of these specs:2GB 204-pin DDR3 SODIMM. Larger than 2GB won't work.1066MHz speed, often expressed as "PC3-8500". Faster modules (higher numbers) are fine; they'll adjust their timing parameters (lower CAS latency, etc.) to function exactly like a 1066MHz module.Non-ECC, unbuffered.256x64 memory organization, single rank. Dual-rank modules (the 16-chip modules mentioned in earlier posts) apparently don't work.1.5V operation. A 1.35V module is ok only if the manufacturer guarantees it to also run at 1.5V.Make sure the NAS is unplugged before you open it up, and wear an anti-static wrist strap when you work on this or any other piece of electronic equipment, especially if you live someplace cold and dry. Amazon sells really nice wrist straps for like $6; that's a lot less than the cost of a new NAS.

The memory test runs in a loop until it encounters a problem or is stopped. If still running after a few hours or so memory should be fine

Dear mdgm,Thank you very much for your anwser.The memory test ran for about 10 hours straight without any problems, when I looked this morning the test still runs.So I can tell my memory should be fine.For people they want to upgrade they memory also:Its Corsair Valueram DDR3 1066 mhz Sodimm CM3X2GSD1066Thanks for your help!

Here it is a DDR3 2 GB SODIMM from Samsung: M471B5773DH0-CH9. The memory test ran for hours now, memory should be fine.

CT51264BC1339 4 GB DDR3 RAM its a 512 x 64 memory module from Crucial mite be the next option. It has 8 x chips seems to only accept modules with 8 x chips only by the look of it. at the moment I am using a 2gb crucial 256 x 64 at the moment and it works fine faster speed ram also 10600 its doing the job

Do not work:
Kingston KVR1333D3S9/4G (4GB, 16 chips)
Nanya NT2GC64B8HA1NS-BE (2GB, 16 chips)
Elpida 2Rx8 PC3-10600S-9-10-F1 (2GB, 16 chips)

I tried this as it was cheap as chips, under £15 quid delivered in the UK. It didn't work.

Have you tried any more yet, Danny?

Maximum amount would be 2GB for Ultra, its Intel Atom Chipset limitation, 4GB memory max, allocated to two slots. (2x2GB)
But as you may already know, Ultra has only one slot available ;)

Thats why Crucial CT51264BC1067 4GB module wouldnt work.
I used 2GB module CT25664BC1067, and it works fine, passed all memtests and so on. :rofl:

Kingston KVR1333D3S8S9/2G works too. Had it for 1 week now and no errors.

http://www.kingston.com/dataSheets/KVR1333D3S8S9_2G.pdf

It has 8 chips in total, 4 on each side.

I use my NAS to stream movies to APTV2. Is there a large gain to be had with upgrading from 1GB to 2GB for uploading and streaming content?
