Server memory upgrade for DDR3 platforms

This 4GB DDR3 1333 module adds ECC registered capacity to compatible servers and workstations. It targets administrators who need to replace failed sticks or expand existing configurations without changing platform infrastructure.

DDR3 1333 registered DIMM interface limits

The PC3-10600 standard caps transfer rates at 1333 MT/s with CL9 latency at 1.50V. Registered buffering reduces electrical load on the memory controller but adds one cycle of latency. Systems must support ECC RDIMM topology and 240-pin DDR3 slots; non-ECC or unbuffered boards will not accept this module.

Major-brand chips on a 240-pin registered PCB

The 1Rx4 organisation uses major-brand components validated through A-Tech quality testing. Registered signalling and ECC circuitry suit 24/7 server workloads where data integrity matters more than raw bandwidth. Builders should confirm their mainboard qualifies this exact density and rank before installation.

Questions about this item

Should I choose the 1Rx4 version or look for a dual-rank alternative?

This module is a single-rank 1Rx4 design, which places less electrical load on the memory controller and can allow higher total capacities on boards with limited rank-per-channel limits.

What does the PC3-10600 rating mean for actual throughput in my server?

PC3-10600 indicates a peak transfer rate of 10 600 MB/s at 1333 MHz; real-world bandwidth will be slightly lower due to protocol overhead and system configuration.

How does the 240-pin registered ECC interface affect compatibility and speed limits?

The 240-pin registered ECC DIMM requires a server or workstation chipset that supports registered modules; it operates at the rated 1333 MHz and 1.5 V standard voltage.
