## Questions & Answers

**Q: Any reason why one can't use a crucial or samsung ram which is same speed for a fraction of the price?**
A: SAMSUNG M471A1K43CB1-CTD 8GB DDR4 will work and not give warnings. Also,  it's double the memory for half the price.

**Q: Just wondering why this is  $90 when you can buy an equivalent piece for $30 elsewhere?**
A: I use cheaper modules and they work fine

**Q: Compatible with DS2419+?**
A: For the price of Synology Branded memory and the fallout for having gotten it wrong, do not trust this type of Q/A to some random stranger off of amazon.  Open Synology's official documentation about what memory is supported in what system and go off of that.

**Q: Is this a synology oem part (d4neso-2666-4g) or is this an off-brand?**
A: It’s Synology branded RAM
