ReadyNAS Ultra 4 (RNDU4220) & RAM upgrade?

There is an old thread here: https://community.netgear.com/t5/New-ReadyNAS-Users-General/Ultra-4-4-gig/td-p/811325 that should help.

I've upgraded the RAM in my Pro-6, but that is of course a different platform.

Granted I own a Pro 2, but i will say that when i doubled the RAM from 1 GB to 2 GB, the system UI was alot quicker and snappy. Unsure if it helped with traffic and throughput as it is just my long term storage backup. I think it is definitely worthwhile, esp as i have upgraded my Pro to run 6.9.5 and kept it somewhat relevant and secure.

All OS-6 Intel ReadyNAS ship with 2 GB or more. I think its a good idea to have at least that much in the converted Pros and Ultras, since Netgear is developing and testing the firmware for platforms with that memory footprint.

I upgraded my Pro-6 RAM in order to support Crashplan backup (which requires a lot of memory). I didn't see any performance speedup for file transfers when I did that. However, I was (and still am) running 4.2.x firmware on that NAS. I do intend to convert it the next time I need to do a factory reset.

  StephenByes thats my point as well. The device is relative old and RAM wasn´t that cheap as its the situation at the moment.
  
  Any advices which RAM would work in the ReadyNAS Ultra 4 (RNDU4220)?
  
  Orginally the device seamed to have a "1GB DDR2 SO-DIMM". According to the forum here (https://community.netgear.com/t5/ReadyNAS-Hardware-Compatibility/upgrade-memory-readynas-ultra/td-p/806953) the chipset would support 4GB via 2 slots. However as the U2 has only one slot a 2GB DIMM seamed to be the max.
  
  Can anybody recommend a working DIMM?

    I believe that, like the Pro2, it's limited to 2GB. Just get something with a speed at least as high as the original. I've not found the ReadyNAS (save the original SPARC NV/NV+) to be especially picky about RAM.
