DDR3 ECC UDIMM kit for workstations and servers

This kit provides two 4 GB unbuffered DIMMs giving a total of 8 GB of DDR3 memory rated at 1600 MT/s with CL11 latency. It is built for desktop workstations, servers and NAS systems that require error-correcting code memory. The modules operate at the standard 1.5 V and use the 240-pin UDIMM form factor. No heat spreaders are included.

Verify DDR3 ECC unbuffered support before purchase

Confirm that your motherboard or system accepts DDR3 ECC unbuffered UDIMMs and has two free 240-pin slots for dual-channel operation. The platform must be able to run memory at 1.5 V and support the PC3-12800 speed grade. Check the vendor’s qualified-vendor list or manual for the exact part number 1E6D32R8008P to ensure compatibility. Do not install in systems that require registered or load-reduced DIMMs.

JEDEC and RoHS compliance simplify deployment

Each module meets JEDEC-standard specifications and is RoHS compliant, so the upgrade is warranty-safe for most OEM workstations and servers. The dual-channel kit is packaged as a matched pair to avoid timing mismatches during installation. OWC tests every module in-house and backs the kit with a limited lifetime warranty and free technical support. No additional software or drivers are required.

Questions about this item

What comes in the box and do I need to buy anything else to install these modules?

The kit includes two 4 GB DDR3 1600 ECC unbuffered UDIMMs, a 240-pin dual-channel pair totalling 8 GB. No extra parts are required for installation in a compatible desktop, workstation or server.

Why choose this 8 GB dual-channel kit instead of a single 8 GB stick?

The matched 2×4 GB pair runs in dual-channel mode, doubling memory bandwidth over a single module and providing the ECC error correction needed for workstation and server workloads.

What does the PC3-12800 1600 MHz CL11 rating mean for my system's actual performance?

PC3-12800 indicates a peak transfer rate of 12 800 MB/s at 1 600 MHz with CAS latency 11, giving low-latency ECC throughput for multi-tasking and large-file workloads on supported platforms.
