Server DDR3 quad kit

This 16 GB kit contains four 4 GB DDR3 1866 modules built for servers and workstations that require ECC unbuffered memory. Each stick is a single-rank 1Rx8 DIMM running at standard 1.5 V with CL13 latency. The kit is not compatible with desktop or laptop platforms.

Thermals and power

Standard 1.5 V DDR3 voltage keeps power draw predictable in multi-DIMM server configurations. Unbuffered ECC operation adds minimal overhead while providing error correction for data integrity. Quad-channel population distributes electrical load evenly across the memory controller.

Build and connectors

Four 240-pin UDIMMs use major-brand chips tested for reliability in continuous operation. Single-rank x8 organisation supports dense population without signal degradation. Modules must be seated according to the system manual to activate quad-channel mode and ensure proper ECC function.

Questions about this item

How do I install the four 240-pin DDR3 modules so the quad-channel kit works correctly?

Shut down the server, open the chassis, align each module notch with the slot key, press firmly until the retention clips lock on both sides, then populate all four slots following the motherboard manual's channel order.

What maintenance or replacement will this ECC UDIMM kit need over its service life?

ECC corrects single-bit errors automatically; no scheduled maintenance is required, and a module is only replaced if the system logs uncorrectable errors or a diagnostic test flags a failure.

At what point does the 1.5 V voltage limit appear first during sustained heavy workloads?

The JEDEC-standard 1.5 V supply is the primary constraint; if the memory controller cannot maintain that voltage under load, the system will throttle or halt before any thermal limit is reached.
