Not "dual-ranked"
March 31st 2024 Verified user
Bought this particular module for a Synology DS224+ (unsupported upgrade) on the basis that it was in stock and described as dual-ranked.

Unfortunately after installing into the NAS, the machine would not boot. I double-checked that the module was inserted correctly and left the NAS on for an extended period, but it would still not boot.

Probing further, I then tested it in an Intel NUC7I3BNH and it was recognised and worked fine.

The output from dmidecode --type 17 was:

Handle 0x0037, DMI type 17, 40 bytes
Memory Device
Array Handle: 0x0035
Error Information Handle: Not Provided
Total Width: 64 bits
Data Width: 64 bits
Size: 16 GB
Form Factor: SODIMM
Set: None

Bank Locator: BANK 2
Type: DDR4
Type Detail: Synchronous

Manufacturer: 0000

Part Number:

Configured Memory Speed: 2133 MT/s
Minimum Voltage: 1.2 V

This output shows the RAM as single rank.

I subsequently bought a Kingston KVR26S19D8/16 which is dual-ranked (2R) and is recognised and working in the Synology.
