What this 8GB DDR3 ECC RDIMM does

This module adds eight gigabytes of registered ECC memory to a compatible server or workstation. It runs at DDR3 1600 with CL11 timing and standard 1.5V voltage. The single-rank 1Rx4 organisation uses Samsung chips on a 240-pin DIMM. Buyers who need non-ECC or unbuffered memory for a desktop board cannot use this module.

Registered DDR3 limits at 1600 MT/s

The registered buffer adds one clock cycle of latency but lets the memory controller drive more modules per channel. DDR3 1600 caps peak bandwidth at the PC3-12800 rate, so workloads that scale with memory throughput will hit that ceiling. Systems that require higher frequencies or lower voltage than 1.5V will not benefit from this part.

Straightforward DIMM installation

Align the notch with the slot key, press firmly until the latches click, and confirm the module seats evenly. The most common issue is mixing registered and unbuffered DIMMs, which prevents the system from posting. Always check the platform’s qualified-vendor list before adding this stick.

Questions about this item

Should I choose the 8 GB DDR3 1600 MHz ECC RDIMM 1Rx4 module or a different capacity for my server?

This module provides 8 GB at DDR3 1600 MHz with ECC and registered buffering; select additional identical modules to reach your platform's supported total capacity and populate channels evenly for best throughput.

What does the PC3-12800 rating mean for actual bandwidth in my workstation?

PC3-12800 indicates a peak transfer rate of 12 800 MB/s per module; real-world throughput will be slightly lower due to protocol overhead and system memory controller efficiency.

Does the 240-pin DDR3 RDIMM interface limit speed or capacity on my motherboard?

The 240-pin DDR3 RDIMM slot caps operation at DDR3 1600 MHz and 1.5 V; maximum capacity per slot and total system memory are defined by your motherboard and CPU memory controller specifications.
