Synology DS1512+ RAM Upgrade to 3GB – A How to Guide

Upgrading your Synology DS1512+ to 3GB of RAM

1. Purchase compatible memory

The first step in your Synology DS1512+ RAM Upgrade is to acquire a compatible RAM module.

Synology states the DS1512+ supports: 2GB -DDR3-1066 unbuffered So-DIMM 204pin CL=7 1.5V

The Synology Community Forum seems to support that the Kingtson KVR1066D3S8S7/2G is the best choice for the DS1512+.  This is what I decided to go with and the upgrade went smoothly.  My DS1512+ passed all memory diagnostics and is running great with this stick of RAM.

Alternatively, there are several other User Reported Compatible RAM modules to choose from.  Just ensure that you purchase a module that is fully compatible with your DS1512+.

6. Lock the RAM module in place

Slowly push the RAM module down until you hear a solid click.  Note the two capture arms on both side should hold the RAM module in a locked position.

    Thanks for the tutorial – very straight forward!

    i just got one of these for our office to use as a raid5 nas backup.
    it seems to be running great – what would be the utility of upgrading the RAM?

    Sorry if this is a stupid question, but would this be more for people using it as a media server?

      The DS1512+ can run a variety of functions (File Server, FTP Server, WebStation, PhotoStation, AudioStation, Cloud Solution, VPN, Surveillance, the list goes on and on…). Additionally, the application store adds a ton of capabilities (Directory Server, DHCP Server, RADIUS Server, Mail Server, DNS Server, and many many more.
      There is a lot you can ask your DS1512+ to do, and the more you ask of it, the more the RAM upgrade will benefit you.
      Even if you are only running a few services, consider your user base as well. If you have a lot of simultaneous connections to the device, a RAM bump can make for a noticeable improvement.
      More is often better, and in this case a relatively inexpensive RAM upgrade will likely serve you well.

    Is your 1512+ still at 3GBs of RAM or did you add more? What are your transfer speeds like with the memory upgrade? Any performance issues with DSM 5?

    I couldn’t figure out how to add to the”User Reported Compatible RAM modules” wiki page, so I thought I’d comment here and hope it helps someone in the future. I just installed a Hynix 2GB PC3 – 10600S – 9 – 10 – B1 HMT325S6BFR8C-H9 NO AA into my Synology DS1512+ without any issue. It took a while to boot up (to recognize the RAM I suppose), but other than that, no problems!

    Brilliant, worked perfectly. Excellent guide.

    Like Kelly, I’m interested in what performance boosts you saw as well.

    The only place the unit was lacking before the upgrade was hardcore 1080p transcoding.
