4GB DDR3 1600 ECC Registered DIMM

This 4GB DDR3 1600 module is built for servers and workstations that require error-correcting registered memory. It operates at PC3-12800 speed with a CL11 latency and standard 1.5V voltage. The single-rank 1Rx4 organisation uses major-brand chips on a 240-pin DIMM. It replaces a long list of HP part numbers including 647648-171, 676811-001 and 647895-B21.

Sustained-load behaviour with ECC registered design

The registered buffer reduces electrical loading on the memory controller, allowing stable operation when all slots are populated. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during continuous workloads. Standard 1.5V power draw keeps thermals predictable inside dense chassis. Quality-assurance testing verifies reliability before the module ships.

Registered ECC requirement decides fit

This module only works in systems that explicitly support DDR3 ECC RDIMM technology; it will not function in desktop boards or laptops that take unbuffered non-ECC DIMMs. Verify your platform’s qualified-vendor list for 1Rx4 registered modules before ordering. Buyers who need unbuffered memory or a different voltage must choose a different part.

Spurningar um þessa vöru

How much power does the 1.5V DDR3 1600 module draw under continuous load?

It operates at the standard 1.5V DDR3 voltage with CL11 latency, so power draw stays within normal registered DIMM limits for 24/7 server use.

What motherboard slot and chipset support are required for this 240-pin RDIMM?

The module needs a DDR3 RDIMM slot that supports registered ECC memory; the 240-pin form factor prevents it from fitting in UDIMM sockets.

Will this 1Rx4 registered stick work alongside older DDR3 ECC modules in the same server?

Yes, if the other modules are also DDR3 registered ECC at 1600 MHz; mixing ranks or voltages can prevent the system from posting.
