Review: Seamless Upgrade for Synology DS923+ – Highly Recommended - 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. Review: 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 3.1 Getting SMBIOS data from sysfs. SMBIOS 3.2.0 present.
