Server Memory Kit

This 64 GB kit consists of two 32 GB DDR3 modules rated at 1066 MT/s with CL11 timings. It targets administrators upgrading or repairing registered-ECC platforms that require 240-pin DIMMs.

Registered ECC Configuration

The modules are 4Rx4 load-reduced registered DIMMs, so the memory controller sees a lighter electrical load per channel. This arrangement frees the platform to populate more slots without exceeding the chipset's rank limit.

Sustained Operation

ECC circuitry corrects single-bit errors on the fly while the registered buffer stabilises signalling during continuous workloads. The CL11 11-11-11-14 timing profile maintains consistent latency across extended duty cycles rather than optimising for short bursts.

Questions about this item

Will the 4Rx4 registered DDR3 modules saturate the 1066 MT/s bus before the CPU under sustained load?

The kit runs at DDR3 1066 (PC3 8500) with CL11 11-11-11-14 timings; registered 4Rx4 organisation lets the memory controller keep the bus full during long workloads.

How much heat and power should I budget for two 32 GB registered sticks running 24/7?

Registered DDR3 1066 modules draw modest power and generate low heat; standard server airflow handles the thermal load without extra cooling.

Does my server mainboard need 240-pin DDR3 slots that support registered ECC memory?

Yes — the kit uses 240-pin DDR3 SDRAM, registered ECC, so the board must accept registered DDR3 DIMMs with ECC enabled.
