OWC 32GB (2X16GB) DDR4 RAM Compatible With Synology DiskStation DS1522+ 2666MHz PC4-21300 CL19 ECC SODIMM 2Rx8 1.2V Memory Upgrade | 32GB (2x16GB) PC4-21300 DDR4 2666MHz ECC Unbuff 2Rx8 CL19 260-pin SODIMM

I recently upgraded my Synology DS923+ with the OWC 32GB (2x16GB) DDR4 RAM, and the experience has been outstanding. Installation was straightforward, and the system recognized the full 32GB immediately without any compatibility issues or warnings.Since the upgrade, I've noticed improved performance, especially when running multiple applications simultaneously. The ECC feature adds an extra layer of reliability, which is crucial for data integrity in a NAS environment.Overall, this memory upgrade has enhanced the efficiency of my NAS setup. I highly recommend this OWC RAM to anyone looking to boost their Synology DS923+'s performance.

Funcionou perfeitamente!Não precisou configurar nada para que as memórias fossem identificados pelo NAS Synology DS923+

This worked excellent on my Synology. I was worried about compatibility and dependability, but I have had zero issues and performance is excellent.

Does not work with DS3622xs+ even though its advertised as if it does.

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 ArrayLocation: System Board Or MotherboardUse: System MemoryError Correction Type: Multi-bit ECCMaximum Capacity: 32 GBError Information Handle: 0x0009Number Of Devices: 2Handle 0x0011, DMI type 17, 40 bytesMemory DeviceArray Handle: 0x000AError Information Handle: 0x0010Total Width: 128 bitsData Width: 64 bitsSize: 16384 MBForm Factor: SODIMMSet: NoneLocator: DIMM 0Bank Locator: P0 CHANNEL AType: DDR4Type Detail: Synchronous Unbuffered (Unregistered)Speed: 2667 MT/sManufacturer: UnknownRank: 2Configured Clock Speed: 2400 MT/sConfigured Voltage: 1.2 VHandle 0x0014, DMI type 17, 40 bytesMemory DeviceArray Handle: 0x000AError Information Handle: 0x0013Total Width: 128 bitsData Width: 64 bitsSize: 16384 MBForm Factor: SODIMMSet: NoneLocator: DIMM 0Bank Locator: P0 CHANNEL BType: DDR4Type Detail: Synchronous Unbuffered (Unregistered)Speed: 2667 MT/sManufacturer: UnknownRank: 2Configured Clock Speed: 2400 MT/sConfigured Voltage: 1.2 V[admin@NAS ~]$

I purchased two modules for my Synology DSM1522+ for use as internal RAM for the server. I have no issues with the modules or their performance.
