32GB DDR3 ECC kit for workstations

This 32GB kit contains four 8GB DDR3 1600 modules built to JEDEC PC3-12800 CL11 specifications. ECC unbuffered operation adds single-bit error correction for data integrity in workstations, servers and NAS systems. The modules run at 1.5V and use the standard 240-pin DIMM form factor.

JEDEC and ROHS compliance simplify upgrades

Full JEDEC compliance means the kit meets the published DDR3 electrical and timing standards without proprietary extensions. ROHS compliance removes restricted substances for broader regulatory acceptance. Together they make the upgrade warranty-safe on systems that require standard-spec memory.

DDR3 1600 interface limits maximum bandwidth

The PC3-12800 rating caps theoretical peak transfer rate at 12800 MB/s per channel. CL11 latency sets the minimum command-to-data delay at eleven cycles. Systems that only support lower DDR3 speeds or non-ECC memory will not gain the rated bandwidth or error-correction benefit.

Questions about this item

Will these 240-pin DDR3 modules fit my desktop motherboard?

The kit uses the standard 240-pin UDIMM form factor for DDR3 desktops, workstations and servers. Check your board manual to confirm it accepts unbuffered ECC DIMMs at 1.5 V.

Can I mix this ECC kit with non-ECC memory already installed?

Mixing ECC and non-ECC DIMMs is not recommended; most platforms will disable ECC or refuse to boot. Replace all modules with this matched 4×8 GB kit for reliable operation.

Does the CL11 latency at 1600 MHz suit a typical workstation workload?

CL11 at 1600 MHz is the standard JEDEC timing for DDR3-1600 and provides stable performance for workstation, server and NAS tasks.
