Review: Great value for NAS memory - Working in my Synology RS1221+ no problem.
Review: Works and tested without errors in Synology DS1522+ with original Synology module - The labels don't say ECC, but it actually does have it, as in the description in desertcart. I wish they put it on the label though. They are actually SK Hynix manufacturered modules (has their label) but seem to be also labeled on the other side by Timetec, so maybe they're just reselling it under their brand. dmidecode does show it's a 3200 MT stick with total width of 74 bits and data width of 64 bits (proving it's ECC), matching the Synology module. Of course the AMD R1600 only uses the modules at 2400 MT only. I ran the memory test using Synology Assistant and it passed. Synology also did not flag the module as unsupported.

### ⭐⭐⭐⭐⭐ Great value for NAS memory
*by A***R on October 2, 2025*

### ⭐⭐⭐⭐⭐ Works and tested without errors in Synology DS1522+ with original Synology module
*by Z***E on December 20, 2023*

The labels don't say ECC, but it actually does have it, as in the description in Amazon. I wish they put it on the label though. They are actually SK Hynix manufacturered modules (has their label) but seem to be also labeled on the other side by Timetec, so maybe they're just reselling it under their brand. dmidecode does show it's a 3200 MT stick with total width of 74 bits and data width of 64 bits (proving it's ECC), matching the Synology module.

### ⭐⭐⭐⭐⭐ Installed 32g (2×16) in Synology 1621+ working well.
*by T***K on February 2, 2022*

Read a lot of reviews here and on synology forums on ECC memory, chose timetec ECC 2x16 because of the greater number of positive 1621/1821/xx21 reviews (like 11 on 2x16) - more that most all others at this price point. Also there was compatibility list in the ad detail so no sweat, no compatibility worries. Memory test from synology assistant passed (5+ hours) no errors. No boot up nags/messages about non-synology memory. Next step allocate 16gb of the 32gb to a couple of VM's (8gb each). Couldn't do that with the stock 4g memory that I will keep and have to put back in if I ever need to get tech support from Synology. Happy Camper saved a ton of money over the way overpriced Synology ECC 2x16 memory - just need to see if it lasts up to the lifetime warranty and USA support. Hope I never need either one.
