Server DDR2 ECC Registered kit

This 16 GB kit contains four 4 GB DDR2 667 modules built for Supermicro X7Dcl-I, X7Dct, X7Dct-10G, X7Dct-3 and X7Dct-3F servers. Each stick is a 240-pin registered DIMM with ECC and a 2Rx4 organisation. The kit targets administrators who need to populate all slots on these platforms with validated memory.

Sustained load behaviour

Registered buffering and ECC correction keep data integrity steady during continuous server workloads. The CL5 5-5-5 timings and 1.8 V operation are maintained across all four modules without throttling. The major-brand chipset supports the rated PC2-5300 bandwidth throughout extended duty cycles.

Thermals, noise and power

Modules run at the standard DDR2 1.8 V with no heat spreader unless current inventory includes one. Power draw stays within the DDR2 specification for registered DIMMs. Passive cooling in a server chassis keeps temperatures in check and adds no audible noise.

Questions about this item

How much heat and power will the 1.8 V DDR2 667 registered DIMMs add when the server runs all day?

Each module operates at 1.8 V with a CL5 5-5-5 timing; registered buffering reduces electrical load on the memory controller, keeping power draw and heat modest for continuous server operation.

What must the system already provide for these four 240-pin DIMMs to function?

A Supermicro X7Dcl-I, X7Dct, X7Dct-10G, X7Dct-3 or X7Dct-3F motherboard with four available 240-pin DDR2 slots that support ECC registered memory at PC2-5300 speed.

Will the 2Rx4 ECC registered kit work alongside older 512 MB or 1 GB DDR2 modules already installed in the same server?

The kit uses major-brand 18-chip 2Rx4 ICs at 667 MHz; mixing ranks or speeds can prevent the board from training, so populated slots should match this specification for stable operation.
