128 GB DDR3 ECC kit for servers

This 128 GB kit contains eight 16 GB DDR3 1066 modules built to the PC3-8500R standard. Each stick is a registered DIMM with ECC and a 4Rx4 quad-rank layout. The kit targets servers and workstations that require registered ECC memory and will not function in desktop or laptop platforms.

Fits registered DDR3 slots

The modules use the 240-pin DDR3 DIMM form factor and operate at the standard 1.5 V. They must be installed in systems that explicitly support DDR3 registered ECC memory with quad-rank modules. Using them releases non-ECC or unbuffered slots for other configurations while providing error correction for critical workloads.

Steady throughput under continuous server loads

Rated at DDR3 1066 with CL7 latency, the memory delivers consistent bandwidth during extended multi-threaded tasks such as virtualization or database serving. Registered buffering and ECC maintain data integrity over long periods without the error accumulation seen in unbuffered alternatives.

Questions about this item

Does the 4Rx4 quad-rank organisation limit the number of modules a memory controller can address?

Each module presents four ranks; most server platforms restrict the total rank count per channel, so eight 4Rx4 DIMMs may exceed that limit depending on the specific system.

What is the power draw and thermal output when all eight 1.5 V modules run continuously?

Operating at the standard 1.5 V DDR3 voltage, the kit draws typical registered DIMM power; sustained loads increase heat, so adequate airflow across the 240-pin slots is required.

Which server or workstation platforms accept 128 GB of DDR3 1066 ECC RDIMM memory?

Only systems that support DDR3 registered ECC DIMMs at 1066 MHz with quad-rank x4 modules can use this kit; verify the motherboard or chassis manual before purchase.
