Server Memory Upgrade

This A-Tech module delivers 8 GB of DDR3 ECC UDIMM capacity for Dell systems using part number A6559261. It targets administrators who need to add reliable memory to compatible servers or workstations without registered DIMM slots. Builders requiring registered or load-reduced memory should select a different module type.

DDR3 1333 PC3-10600 Specification

The module runs at 1333 MHz with CL9 latency at 1.50 V across 240 pins. Its 2Rx8 unbuffered ECC organisation is the single attribute that determines whether the host platform will accept it. Systems that demand registered signalling or a different rank configuration will not recognise this DIMM.

Sustained Workload Behaviour

Major-brand chips and full qualification testing keep error correction active during continuous server duties such as virtualisation hosting or database caching. The standard 1.5 V DDR3 voltage maintains stable throughput over long periods without the thermal spikes seen in higher-voltage enthusiast parts.

Questions about this item

What does the 1333 MHz speed mean once this module is installed in a server?

The module operates at DDR3 1333 (PC3-10600) with CL9 latency at 1.5 V, providing standard DDR3 bandwidth for the memory controller.

How does the ECC UDIMM interface affect what the module can do in practice?

ECC UDIMM adds single-bit error correction without registered buffering, so the memory controller handles address and command signals directly.

What physical slot and pin count does this 240-pin DIMM need to fit?

It requires a standard DDR3 240-pin UDIMM socket with 1.5 V keying; the 2Rx8 organisation fits any slot that accepts unbuffered ECC DIMMs.
