4GB DDR3 ECC UDIMM for Dell Servers

This 4GB DDR3 1600 ECC UDIMM module is built for Dell systems using part SNPWM5YYC/4G. It targets administrators maintaining compatible servers or workstations that require error-correcting unbuffered memory. The single 240-pin DIMM installs directly into standard DDR3 slots on qualified platforms.

Capacity and headroom for DDR3 workloads

The module provides 4GB of PC3-12800 memory running at 1600MHz with CL11 latency. ECC protection detects and corrects single-bit errors to maintain data integrity under sustained loads. Unbuffered design suits platforms that do not support registered DIMMs. Capacity limits appear when applications exceed the 4GB footprint per module.

Major-brand chips on a standard 240-pin build

Major-brand components are assembled on a 240-pin DDR3 PCB operating at 1.50V standard voltage. The 2Rx8 rank organisation fits the electrical layout expected by compatible Dell boards. Unbuffered signalling keeps trace routing straightforward for qualified motherboards. Lifetime warranty and US-based technical support back the module after installation.

Questions about this item

Will this DDR3 1600 CL11 ECC UDIMM work alongside my existing DDR3 modules in a Dell server?

This module runs at DDR3 1600 (PC3-12800) with CL11 latency and 1.5V. Mixing speeds causes the system to run all modules at the slowest installed speed; verify your current modules match these specifications for best stability.

How can I confirm the 4GB 2Rx8 ECC UDIMM is recognised and running at 1600MHz after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should show 4GB total capacity, 1600MHz operating speed, ECC enabled, and the module identified as unbuffered (UDIMM) with 2Rx8 organisation.

Does the single 240-pin DDR3 DIMM ship alone, or are brackets, cables or a heat spreader included?

The package contains only the 4GB DDR3 1600 ECC UDIMM module (240-pin DIMM). No brackets, cables, heat spreaders or additional accessories are supplied; the module installs directly into a compatible DDR3 DIMM slot.
