## Description

Samsung 4GB DDR4 PC4-21300 2666MHz 260pin SODIMM Memory M471A5244CB0-CTD

Review: Easy if yk what your doing - Worked just as described and easy to put in
Review: Excellent memory expansion option for Synology DS220+ - I wasn't willing to pay the ridiculous Synology price for the official memory expansion card, so I looked at the specs, and decided that this Samsung 4GB card would meet my needs nicely, while still staying within the official 6GB maximum. Installation is quite easy: you shutdown and disconnect the box, take out one of the drives (on the side with the memory card slot), carefully insert the new card at a slight angle, then press down gently until it clicks into place with the retaining clips. Then restart, and check the system info to confirm that you have 6GB memory. I experienced no problems throughout this process. Note: if you do a web search, you'll see various sites discussing the addition of an 8GB or 16GB chip, supposedly this works because the system board supports it. I didn't go there because my system isn't going to be heavily loaded (I use it as a NAS, that's it), so it wasn't worthwhile for me. I seem to have sufficient headroom for all my anticipated needs, and the system performance is more than adequate.

**Q: My ram slots are mirrored so i'd have to install this upside down to get it to line up. it will only fit in the left hand slot. what am i missing?**
A: First, I would check to be sure the ram module is for your computer model.  Second, check the pin alignment for each side.  Third, try flipping one of the ram to see if that lines up with the pins.  Best wishes.

### ⭐⭐⭐⭐⭐ Works perfect in Synology DS920+
*by D***N on September 24, 2022*

Figured I'd max out the RAM in my Synology DS920+ and went ahead and picked up this module since the price was really low. Not really needed right now but figured why not...cheap upgrade. Installed easy, with no errors. Synology NAS arrays can be picky when it comes to RAM chips and NVMe SSDs used for cache. I'm pretty sure the RAM chips soldered on the board that come with the NAS are Samsung but rebranded.
