Memory test ReadyNAS Ultra 2

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:

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.
