4 GB Registered DDR3 Module

This 4 GB DDR3 module runs at 1333 MT/s with a PC3-10600 rating. It uses a registered design and operates at 1.50 V. The 240-pin DIMM targets desktop workstations and entry servers that require registered memory.

Verify Registered Memory Support

Confirm the motherboard accepts registered DDR3 DIMMs before ordering. Many consumer desktop boards only support unbuffered modules and will not post with this stick. Check the manual for explicit registered memory qualification and ensure a free 240-pin slot is available.

Registered DIMM for Compatible Platforms

The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-DIMM configurations on supported chipsets. It frees the builder from seeking unbuffered ECC alternatives when the platform mandates registered modules. The single 4 GB stick leaves additional slots open for future capacity expansion.
