8GB DDR3 1600MHz ECC RDIMM

This 8GB DDR3 1600MHz ECC registered DIMM is built for server and workstation systems that require registered memory with error correction. It operates at 1.5V with CL11 latency and uses a 2Rx4 rank configuration on a 240-pin module.

Suits Dell part-number match

This module replaces Dell part numbers A5681559, A5681561, A5816804, A5816812, A5816819 and SNPRYK18C/8G, making it a direct fit for compatible Dell servers and workstations. Builders whose systems need unbuffered UDIMMs, non-ECC memory, or a different DDR generation should select another module.

Registered ECC DDR3 1600MHz requirement

The system must support DDR3 1600MHz registered ECC RDIMM memory at 1.5V; if the platform requires unbuffered, non-ECC, or a different speed, this module will not function.

Questions about this item

What does the DDR3 1600 PC3-12800 interface mean for real-world throughput?

The module runs at 1600 MHz with a PC3-12800 rating, so its peak transfer rate is 12800 MB/s. Actual throughput depends on the server's memory controller and channel configuration.

What physical slot and clearance does this 240-pin DDR3 RDIMM require?

It needs a standard 240-pin DDR3 DIMM slot. The registered design adds a register chip on the PCB, so verify the motherboard supports registered memory and that heatsink clearance is adequate.

What is the correct installation sequence for this registered ECC module, and what step is often missed?

Power down, open the chassis, align the notch with the 240-pin slot, press firmly until both latches click. The step often missed is confirming the BIOS recognises the module as ECC registered at 1600 MHz.
