Server memory kit for Intel-validated platforms

This 64GB kit contains four 16GB DDR3 registered DIMMs with ECC and a thermal sensor. It targets system builders and integrators who need reliable capacity for Intel-validated servers and workstations.

Registered ECC at CL11 1600 speed

Each module runs at DDR3 1600 with CAS latency 11 and 1.50V on a 240-pin interface. The registered design and ECC support are the decisive specifications for compatibility with server chipsets that require buffered memory.

Steady throughput under continuous load

JEDEC-compliant validation and the onboard thermal sensor help maintain consistent operation during sustained workloads. The registered buffer reduces electrical load on the memory controller, supporting stable data integrity over long periods.

Questions about this item

What does the 1600 MHz speed and CL11 latency mean for real-world server throughput?

The kit runs at DDR3 1600 with CAS latency 11, giving each 16 GB module the standard JEDEC data rate for that speed grade; ECC and registered buffering add one cycle of address delay but protect data integrity.

How does the 240-pin DDR3 registered interface limit memory capacity or channel population?

Each stick is a 240-pin DDR3 registered DIMM; the register reduces electrical load on the memory controller, allowing more modules per channel than unbuffered DIMMs, but the motherboard chipset still sets the maximum total capacity and supported ranks.

What physical space and power connectors do the four 16 GB sticks require?

Four 240-pin DDR3 DIMMs occupy four full-height DIMM slots and draw 1.50 V from the slot; the modules include an on-board thermal sensor but need no extra power cables or heatsink clearance beyond standard server DIMM spacing.
