Server memory kit for DDR3 platforms

This 32 GB kit contains four 8 GB DDR3 1866 ECC RDIMM modules built for registered server and workstation boards. Each module runs at 1.5 V with CL13 latency and a single-rank x4 layout. The quad-channel pack is intended for multi-socket systems that require registered error-correcting memory.

Steady throughput under registered ECC load

Registered buffering and on-die ECC keep data integrity intact during continuous multi-threaded workloads such as virtualisation hosts or database engines. Single-rank x4 organisation allows all four DIMMs to populate a channel without exceeding typical rank limits, sustaining bandwidth over long runs rather than short bursts.

Verify DDR3 registered DIMM support first

Confirm the motherboard accepts 240-pin DDR3 RDIMMs at 1.5 V and can address 32 GB across four slots in quad-channel mode. Systems limited to unbuffered UDIMMs or to a different DDR generation will not post with these modules. Check the vendor memory-qualified list for exact population rules.

Questions about this item

How much power does this 1.5V DDR3 1866 kit draw when the server runs continuously?

Each module operates at the standard DDR3 voltage of 1.50V; total system draw depends on the platform and workload rather than the memory alone.

What must my motherboard provide to run this quad-channel 240-pin ECC RDIMM kit?

The board needs four DDR3 240-pin slots, a memory controller that supports registered ECC DIMMs, and BIOS that can initialise 1Rx4 modules at 1866 MHz.

Can I mix these 1Rx4 registered sticks with older unbuffered DDR3 DIMMs I already own?

No — registered and unbuffered DDR3 cannot be used together, and the memory controller must be configured for one type exclusively.
