Server-grade ECC RDIMM for Dell PowerEdge

This 8GB DDR3 registered DIMM delivers error-correcting memory for Dell PowerEdge C2100, C6105, M910, R810 and R910 servers. It operates at 1333MHz with CL9 latency and 1.5V voltage. The module uses a 2Rx4 organisation and 240-pin form factor. It is not compatible with standard desktop computers or unbuffered memory configurations.

Sustained reliability under continuous workloads

ECC registration corrects single-bit errors and detects multi-bit errors during extended operation, reducing the risk of data corruption in always-on environments. Registered signalling lowers electrical load on the memory controller, allowing stable performance across fully populated slots. JEDEC-compliant construction and laboratory testing support consistent throughput in multi-user server and NAS deployments.

Registered ECC requirement decides fit

This module only works in systems that require registered ECC DDR3 memory; it will not function in platforms that accept only unbuffered non-ECC DIMMs. Buyers needing standard desktop memory or non-ECC server modules cannot use this part. Verify that the target Dell PowerEdge model specifies registered ECC support before purchase.

Questions about this item

How much power does the 1.5V DDR3 1333 module draw when the server runs continuously?

The module operates at 1.5V, the standard voltage for DDR3 1333 registered DIMMs, so power draw matches the JEDEC specification for that speed and voltage.

What must the Dell PowerEdge already have to accept this 240-pin ECC RDIMM?

The system must be a Dell PowerEdge C2100, C6105, M910, R810 or R910 with free 240-pin DDR3 slots that support registered ECC memory.

Can this 2Rx4 CL9 stick run alongside older 1Rx4 DDR3 modules in the same R810?

Mixing ranks is possible if the platform's memory controller supports it, but registered ECC cannot be mixed with unbuffered memory and all modules must run at the same 1333 MT/s speed.
