ECC UDIMM for Synology NAS

This 8 GB DDR3 module runs at 1600 MHz with CL11 latency and 1.50 V operation. It uses a 240-pin unbuffered DIMM design and carries ECC for data-integrity protection in server workloads. The 2Rx8 organisation with major-brand chips targets reliable uptime in compatible systems.

Builders needing registered or load-reduced memory cannot use this unbuffered stick. Buyers who want more capacity per slot or a faster DDR3 speed grade should look at something else.

DDR3 1600 MHz CL11 ECC UDIMM 2Rx8

The 1600 MHz CL11 timing at 1.50 V decides whether the module matches the platform's qualified-vendor list. Verify the system's supported memory specifications before purchase to confirm compatibility.

Questions about this item

Should I choose the single 8GB module or a 2x8GB kit for my Synology?

The listing is a single 8GB DDR3 1600MHz ECC UDIMM; add a second identical module to run dual-channel if your NAS has two slots.

What does PC3-12800 mean for actual throughput in my server?

PC3-12800 is the JEDEC designation for DDR3 1600MHz, so the module runs at that data rate when the platform supports it.

Is this ECC UDIMM compatible with standard DDR3 DIMM slots?

Yes, it uses the 240-pin DDR3 DIMM form factor and fits any slot wired for unbuffered ECC memory at 1.5V.
