OWC 32GB (2X16GB) ECC DDR4 RAM – works with QNAP TS-h973AX
Purchased this OWC 32GB (2x 16GB) DDR4 2666MHz PC4-21300 CL19 ECC SODIMM 2Rx8 1.2V (OWC2C6D42R8032P) hoping it will work with QNAP TS-h973AX that accepts ECC memory but came with regular DDR4.Installation took 30 seconds (it took longer to power off the NAS and remove HDDs to get access to memory slots), powered the QNAP TS-h973AX on, and…viola, 32GB memory was recognized!Memory is Made in Taiwan (not China!) and uses SK Hynix DRAM modules. Runs fine for 3 days so far, convinced that should I have any issues, OWC will provide a promised limited lifetime warranty. Price was also lower than other ECC modules everywhere, even the no-name ones.[admin@NAS ~]$ sudo dmidecode -t memory# dmidecode 3.1Getting SMBIOS data from sysfs.SMBIOS 3.2.0 present.Handle 0x000A, DMI type 16, 23 bytesPhysical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 32 GB Error Information Handle: 0x0009 Number Of Devices: 2Handle 0x0011, DMI type 17, 40 bytesMemory Device Array Handle: 0x000A Error Information Handle: 0x0010 Total Width: 128 bits Data Width: 64 bits Size: 16384 MB Form Factor: SODIMM Set: None Locator: DIMM 0 Bank Locator: P0 CHANNEL A Type: DDR4 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 2667 MT/s Manufacturer: Unknown Rank: 2 Configured Clock Speed: 2400 MT/s Configured Voltage: 1.2 VHandle 0x0014, DMI type 17, 40 bytesMemory Device Array Handle: 0x000A Error Information Handle: 0x0013 Total Width: 128 bits Data Width: 64 bits Size: 16384 MB Form Factor: SODIMM Set: None Locator: DIMM 0 Bank Locator: P0 CHANNEL B Type: DDR4 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 2667 MT/s Manufacturer: Unknown Rank: 2 Configured Clock Speed: 2400 MT/s Configured Voltage: 1.2 V[admin@NAS ~]$

Working on Synology Diskstation 1522+
We’ve all wanted to upgrade the RAM in our Synology Diskstations to run more docker containers, virtual machines, or packages. But GOOD LORD does Synology overcharge for RAM. I mean, even Tim Cook is jealous of how much Synology gets away with overcharging for RAM.Saw this listing for RAM compatible with my Synology Diskstation 1522+, and at nearly ONE TENTH(!!!) of the price of the official Synology module, figured I would give it a shot.Chips are SK Hynix as the other reviewer reported. Slapped it in the Diskstation, booted right up, no issues so far. Extremely thankful for OWC for providing these modules at fair prices.Going to stay vigilant for the next month or so to see if any latent errors or crashes occur. If they do, I will update this review. But so far I’m satisfied.ONE MONTH UPDATE: I have been running these modules for about a month and have not experienced any issues. Diskstation 1522+ is running solid with tons of containers and VMs, no crashes or resets or anything like that.TWO MONTH UPDATE: Still no issues, working great.

Ease of use and faultless performance
Only issue I had with installation was not the card but NAS memory holding slot locking mechanism. Small and delicate. Good thing I don’t need to access the card very often or if ever. I’ve maxed out the memory and should not need to mess with this slight bit of metal, about the size of a small earing, and just as cumbersome to work with.

Works without issue in my Synology 1522+
These were easy to install and showed up as 32GB RAM in my Synology 1522+. No issues detecting or any compatibility issues. Able to now run more docker containers along with some VMs without worry about RAM issues.

Perfect for DS1522+ as noted!
Great, worked perfectly! Then the original module from 1522+ went in perfectly to a 923+.

Excellent ram for DS1522+
Was able to upgrade my DS1522+ with this, giving a lot more room for cache, and with my 10gb backhaul, this makes things fly on my network.
