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.
Qnap TS-469L Cover removed
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
Top – Kingston 2GB DDR3 KVR1333D3S8S9/2G Bottom – Samsung 2GB DDR3 M471B5773DH0-CH9
Once fitted the Samsung M471B5773DH0-CH9 worked perfectly, with a noticeable speed increase.
how has it been so far? is it stable? and is there any reason why you didn’t upgrade to the 3gb module?
It’s been very stable.
I’m not sure they do a 3gb module.
After reading this page i went out and got Samsung M471B5773DH0-CH9 2gig RAM and can also confirm this works
Thanks a lot!
Worked great for me too. Thanks !
Worked for me, thanks for the heads up on the Samsung module!
Thanks for the information provided. I just order mine from Amazon. $10.34 USD, nice!
Thank you! Works very well on my TS-469L! Spent 18€ !
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
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
I show 3000mb ram
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?!
Here the same. Exactly the same samsung module.
Yes. It is perfectly worked for ts-269 pro too.
I just installed Crucial 2GB CT25664BF160B on my TS-269L and it works perfectly (after trying several others without success).
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!
