8GB DDR3 1600 ECC UDIMM

This module is an 8GB DDR3 1600 (PC3-12800) ECC unbuffered UDIMM rated at CL11 and 1.5V. It uses a 240-pin 2Rx8 design without a heat spreader and is built to JEDEC and RoHS standards for warranty-safe upgrades.

Workstations, servers and NAS systems

The specification targets workstations, servers and NAS platforms that require ECC unbuffered DDR3 memory. Systems needing registered or fully buffered DIMMs, non-ECC modules, or a different voltage should select a different part.

ECC unbuffered DDR3 1600 at 1.5V

The deciding specification is the combination of ECC unbuffered operation at DDR3 1600 with a 1.5V supply; only motherboards and chassis designed for that exact electrical and signalling profile will accept the module.

Perguntas sobre este artigo

Will this 8 GB DDR3 1600 CL11 ECC UDIMM fit my QNAP NAS that uses part numbers RAM-8GDR3EC-LD-1600 or RAM-8GDR3-LD-1600?

Yes. The module is built to the exact same specifications — 8 GB, DDR3 1600, PC3-12800, CL11, 2Rx8, 240-pin, 1.5 V, ECC unbuffered — so it replaces those QNAP parts directly.

My motherboard has standard 240-pin DDR3 slots but does not support ECC; can I still use this memory?

Most consumer boards will accept the DIMM physically, but they will ignore the ECC function and may not boot with it. Check the board manual or vendor QVL to confirm ECC unbuffered support before purchasing.

What do the numbers PC3-12800 and CL11 mean for real-world use?

PC3-12800 indicates a peak transfer rate of 12 800 MB/s at 1600 MHz, while CL11 means the column address strobe latency is 11 cycles; together they describe the module’s rated speed and timing for compatible systems.
