Qnap RAM Memory Upgrade

I’ve had a Qnap TS 469L for a while now, the standard 1GB physical RAM has always hovered around 80% used with a 400-500Mb Swap file in use, in order to try and speed up the responsiveness of the unit I looked into upgrading the RAM from 1GB to 3GB for the claimed 48% improvement in speed.

The best price I could find for official Qnap ram was £89. this was a bit expensive for me so I looked into alternatives.  Kingston 2GB DDR3 KVR1333D3S8S9/2G appeared to have  worked so I purchased a stick from eBay

The upgrade is really easy to do, just remove 3 screws, slide the cover off, pop in the new ram into the slot and turn it on. http://www.qnap.com/index.php?sn=4605 On powering up with the Kingston RAM installed all I got was the HDD lights flashing slowly red, I removed the Kingston RAM and lucky no damage had been done and every thing power back up fine.

After a bit of digging on Google if found a blog by Cyconet who had also experienced problems with the kingston RAM it turns out there are 2 different designs of ram it seems essentially that the module has a 8-chip design. The Kingston module has only 8 memory chips, but the design is a 16 chip chip both using the same part number and only the 8 chip version works with the Qnap NAS, so I ordered a Samsung M471B5773DH0-CH9

Once fitted the Samsung M471B5773DH0-CH9 worked perfectly, with a noticeable speed increase.

  1. After reading this page i went out and got Samsung M471B5773DH0-CH9 2gig RAM and can also confirm this works
    Thanks a lot!

  2. Very helpful, did you add the 2GB stick or replace the existing one with the new 2GB? After the install, did you have a total of 3 or 2? Thanks

  3. I have a similar question to Drew ^, i have a 469L also upgraded to 3Gb but the RAM usage with the latest FW and Q centre is requiring > 70% usage, i would like some buffer… can the original 1GB mod. be replaced in the 469L

  4. Hi, I had the same problem as you did with the Kingston card and was hopeful when I read your post, however I just tried using the samsung (exact same) on my 469L but doesn’t power up correctly. Not sure what I’m doing wrong?!

  5. I just installed Crucial 2GB CT25664BF160B on my TS-269L and it works perfectly (after trying several others without success).

  6. Ordered the Samsung memory on ebay for 7 euro, stuck it in my TS-469L (after removing a couple of years worth of dust), worked right away. Web interface and the whole NAS feels as responsive as it should have done from start. Thanks!
