4GB RAM Replacement for Dell A6994474 | DDR3 1600MHz PC3L-12800 ECC RDIMM 2Rx8 Server Memory

This A-Tech 4GB DDR3L-1600 ECC Registered DIMM is a server-memory replacement for Dell A6994474, suited to compatible servers and workstations that support 240-pin, 1.35V, 2Rx8 RDIMMs.

Recommended For

• Owners of a Dell PowerEdge R320 or another verified DDR3 system who need a like-for-like 4GB ECC registered DIMM replacement; Dell lists 4GB dual-rank RDIMMs among the R320’s supported memory capacities.
• Dell Precision R7610 operators maintaining an older workstation who need a single 4GB DDR3 ECC RDIMM module; Dell documents 4GB RDIMMs as a supported capacity for that system.
• IT technicians and homelab maintainers servicing a compatible legacy server or workstation who want one 4GB registered ECC DIMM for a targeted repair or small-capacity replacement, rather than a major memory expansion.

Real-World Use Scenarios

• When a compatible Dell PowerEdge reports a failed memory module, replace the defective DIMM to help restore normal startup and operation; confirm the server supports this module type and configuration first.
• When maintaining a compatible older server, add this module to increase installed memory in a small increment; the extra capacity may help when the existing configuration is short on RAM, but the benefit depends on the server’s total memory and workload.
• For a home lab using a compatible DDR3 server, add the module as part of a larger memory configuration for light services or testing; one 4GB module alone is a limited amount of memory for running multiple virtual machines.
• When adding memory to a server that already has DIMMs installed, use it only if the system supports registered ECC memory and the module fits its population rules; the system may run memory at a lower speed depending on the installed DIMMs and configuration.
