4GB DDR3 1333MHz ECC RDIMM

This 4GB DDR3 1333MHz ECC Registered DIMM is built for servers and workstations that require error-correcting memory. It operates at PC3-10600 speed with CL9 latency and a standard 1.50V supply. The module uses a 2Rx8 organisation and major-brand chips on a 240-pin form factor. It serves as a direct replacement for the Crucial CT51272BB1339 part number.

Sustained-load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute runs. Major-brand chips are tested to meet stringent quality standards for dependable operation under continuous workloads. The CL9 timing delivers consistent latency for predictable throughput.

Thermals noise and power at 1.50V standard voltage

Running at the standard DDR3 voltage of 1.50V keeps power draw within normal limits for registered server memory. Passive cooling via system airflow is sufficient; no active fan or heatsink is required on the module itself. The component produces no audible noise during operation. Compatibility with the target platform should be verified before installation to ensure proper electrical and firmware support.

Questions about this item

How much power does a 1.5V DDR3 1333MHz ECC RDIMM draw when the server runs continuously?

This registered DDR3 module operates at the standard 1.5V supply voltage. Actual power draw depends on the server platform and workload, but registered DIMMs typically consume slightly more power than unbuffered modules due to the onboard register.

What motherboard slot and chipset support are required for this 240-pin registered ECC DDR3 module?

You need a server or workstation motherboard with DDR3 240-pin DIMM slots that explicitly support registered ECC memory. Consumer desktop boards generally do not support registered DIMMs.

Can this 2Rx8 PC3-10600 registered DIMM be mixed with older unbuffered ECC DDR3 sticks in the same system?

Registered and unbuffered ECC DIMMs cannot be mixed in the same memory channel or system. All installed modules must be registered ECC for the server to POST and operate correctly.
