Server Memory Upgrade

This 8 GB DDR3 1333 MHz module is a registered ECC DIMM built for Dell servers and workstations. It replaces part numbers A3721483, A3858996, A4051416, A4105734, A4188276 and PK4TR. The 2Rx4 organisation and 1.5 V operation suit systems that require registered memory with error correction. Buyers needing unbuffered or non-ECC modules cannot use this product.

Build Integration

The 240-pin DIMM plugs into standard DDR3 server slots and draws 1.5 V from the platform. Registered buffering reduces electrical load on the memory controller, freeing headroom for larger memory populations. Systems that only accept unregistered DIMMs or that lack ECC support will not accept this module.

Sustained Workload Behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, protecting data integrity under heavy multitasking. Major-brand chips and CL9 latency deliver stable throughput for extended server tasks. The registered design maintains signal quality across fully populated channels without the timing drift seen in unbuffered configurations.

Questions about this item

Does the 1.50 V DDR3 voltage limit how many modules I can run continuously in a fully populated server?

The module operates at the standard 1.50 V for DDR3 1333, so power draw per DIMM is predictable; total system power will scale with the number of slots you fill.

How much heat and noise should I expect from this 2Rx4 registered ECC DIMM during 24/7 operation?

Registered ECC DIMMs run passively with no moving parts; heat output is low and any noise comes only from chassis fans, not the memory itself.

My Dell server needs DDR3 1333 RDIMMs — will this 240-pin module work without a BIOS update?

The 240-pin DDR3 1333 RDIMM matches the form factor and speed for the listed Dell part numbers A3721483, A3858996, A4051416, A4105734, A4188276 and PK4TR.
