Fit perfectly in my Synology DS923+ NAS, with all 32g recognized and working like the NAS came with it from the factory with a great price to boot. I've used OWC for other applications in the past, and has always been a quality product; this purchase was no exception.

Worked perfectly in Synology DS923+ !!!There was no warning message in the Synology DSM interface that you aren't using their brand name RAM.

Cheapest that I could find - installed and works a charm., now have 32GB in my Synology 923+ NAS. Was worried about the time to deliver, but it was clearly stated and the tracking information was regularly updated.

I could not justify paying Synology's price for RAM SIMMs. RAM has been generic for decades -- and I'm someone who opened the original MacPlus and installed RAM SIMMs. For anyone curious, the Synology labelled RAM isn't even consistently from the same vendor so how exactly are they 'confirming' the quality?Anyway, I've never had a problem with any RAM sold under the OWC label. Other World Computing has been my go-to source for RAM for my Mac devices going all the way back to the MacPlus in 1988 so I figured if they were able to consistently get products to work with Apple's tech, then Synology should be a breeze. And so far, six months on, my DS923+ hasn't made a single chirp about the RAM not being Synology branded and works perfectly well. Considering I got 32gb for less than the price of a single 4gb Simm with a Synology sticker? I figure it was money well spent.

Unit powered right up and is now actually able to run VMs without running out of memory!

I used them for the Synology Nas DS723+ and when placed correctly, they will be recognized immediately. The Nas doesn't take longer to startup (just like regular) and the Memory test passed successfully. Just be sure not to use the 10G port for the test, but one of the build in 1G ports. (Otherwise it doesn't work)

Not listed by Synology as compatible. It works with Synology. However, I don't know the performance compared to Synology. You want performance. Buy Synology. Worked well enough while very low priced for the average Joe/Jane, including you. Cheers.

Very affordable ECC memory for my Synology DS923+ NAS.Works perfectly and saves a bunch of money over factory memory.

+ works with speeds as advertised.+ fair value from seller considering it’s a low volume import+ good packagingSince I’m using it in my DS923+ Synology NAS, I did not test extended speeds or overclocking (which is how usually quality is inferred.)One interesting observation - these sticks run cooler and does not get as hot.

My DS1522+ already came with one 8GB stick. This was extremely easy to install and despite synology DSM claiming it “may not be” compatible, it is 100% compatible and in perfect working order. Big upgrade for a very cheap price! No brainer purchase.

Installed in it 5min. No error no warning. Worked as advertised. Way cheaper than Synology branded RAM but only time will tell if it last as long.
