Targeted Server Upgrade

This 4GB DDR3 1600MHz ECC RDIMM module replaces the Kingston KVR16R11S4/4HC in compatible server and workstation systems. It delivers registered error-correcting memory for workloads that demand data integrity and stable multitasking performance.

Registered DIMM Build

The 240-pin DDR3 form factor fits standard server DIMM slots and operates at the standard 1.5V DDR3 voltage. Registered buffering reduces electrical load on the memory controller, while ECC circuitry detects and corrects single-bit errors during continuous operation.

Lifetime Verified Reliability

Every module undergoes quality assurance testing before shipment to confirm dependable performance in supported platforms. A-Tech backs the memory with a lifetime warranty and provides US-based technical support for installation guidance and compatibility questions.

Questions about this item

What does the DDR3 1600 PC3-12800 rating mean for real-world bandwidth?

The module runs at 1600 MT/s with a PC3-12800 designation, matching the Kingston KVR16R11S4/4HC specification.

Will this 240-pin RDIMM fit my server board?

It uses a standard 240-pin DDR3 DIMM form factor with registered signalling; the board must accept registered ECC modules.

What BIOS step do people skip when adding this ECC RDIMM?

Enable ECC and registered mode in BIOS before booting; many forget to save the setting so the module runs as non-ECC.
