Server memory upgrade

This 8 GB DDR3 ECC UDIMM module runs at 1600 MHz with CL11 latency and 1.50 V operation. It uses a 240-pin form factor and 2Rx8 rank organisation for compatible Dell systems. The unbuffered design suits workstations and servers that require error-correcting memory without registered signalling.

Sustained workload behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preserving data integrity under long-running server loads. The major-brand chipset and 1.5 V standard voltage maintain stable timing across extended sessions. Quality assurance testing validates reliability for environments where uptime matters more than peak burst speed.

DDR3 interface limits

The PC3-12800 rating defines the maximum bandwidth available on the DDR3 1600 bus, capping throughput regardless of module capacity. Unbuffered topology restricts the number of modules a memory controller can address compared with registered alternatives. Builders needing larger total memory or higher frequencies must move to a newer memory generation.

Questions about this item

How much power does this 1.5V DDR3 1600MHz ECC UDIMM draw during continuous server workloads?

The module operates at the standard DDR3 voltage of 1.5V with a CL11 latency, typical for unbuffered ECC DIMMs in 24/7 server environments.

Does my Dell server need a specific chipset or BIOS revision to recognise this A6996784-compatible 2Rx8 stick?

This 240-pin DDR3 ECC UDIMM is built as a direct replacement for Dell part A6996784; verify your system's qualified-vendor list before installing.

Will this CL11 2Rx8 DDR3 1600 module run reliably alongside older DDR3 DIMMs already installed in my workstation?

Mixing ranks, speeds or latencies can cause instability; for best results populate all channels with identical 1600MHz CL11 2Rx8 modules.
