8GB DDR3 ECC Registered Module

This 8GB Samsung DDR3 module runs at 1333 MT/s with CL9 latency and 1.35V operation. It is a registered ECC DIMM built for server platforms that require error correction and signal buffering. The 2Rx4 dual-rank layout fits standard 240-pin slots.

Verify DDR3 Registered ECC Support

Confirm your motherboard accepts DDR3 registered ECC memory before ordering. Consumer boards often reject registered modules or disable ECC functionality. Check the vendor documentation for qualified DIMM populations and maximum supported capacity per channel. This module requires a 240-pin DDR3 slot.

Suited for Compatible Server Upgrades

Ideal for administrators expanding memory in validated DDR3 server systems that specify registered ECC DIMMs. Not suitable for desktop PCs, laptops, or workstations that require unbuffered non-ECC memory. Buyers needing higher speeds, different voltages, or larger single-module capacities should look elsewhere.

Questions about this item

Does the 240-pin DDR3 module arrive as a single 8 GB stick or do I need to buy anything else to install it?

The module is a single 8 GB 240-pin DDR3 DIMM; no extra parts are required for installation.

Why choose the 1.35 V 2Rx4 registered version instead of a standard unbuffered kit?

The 1.35 V 2Rx4 registered design adds ECC error correction and signal buffering, which are required by many server motherboards.

What does the DDR3 1333 CL9 rating deliver once the module is seated in a server?

It runs at 1333 MT/s with CL9 latency at 1.35 V, providing ECC-protected throughput for compatible DDR3 server platforms.
