Server memory kit

This 32GB kit contains four 8GB DDR4 modules rated at 2133 MHz with CL15 latency and 1.20V operation. It is built for servers and workstations that require registered ECC memory and will not function in desktop or laptop systems.

Sustained workload behaviour

Registered ECC modules add a clock cycle for command buffering and perform continuous error correction, keeping data integrity intact during long compute runs. The dual-rank 2Rx8 organisation lets each channel interleave requests, which helps maintain steady throughput when all four DIMMs are populated.

Upgrade scope

The kit replaces non-ECC or unbuffered DIMMs in platforms that mandate registered memory, and it expands capacity in 288-pin DDR4 slots that support quad-channel configurations. Systems limited to lower speeds or single-rank populations will not gain the full benefit.

Questions about this item

Does the 1.2V DDR4 2133 kit run cool and quiet in a server chassis all day?

The modules operate at standard 1.2V DDR4 voltage with no active cooling, so they add minimal heat and make no noise during continuous operation.

What must my system already support to use this 288-pin ECC RDIMM kit?

Your server or workstation must accept DDR4 Registered ECC DIMMs, provide four 288-pin slots, and support quad-channel memory architecture.

Can I mix these dual-rank 2Rx8 modules with older single-rank DDR4 RDIMMs I already have?

Mixing ranks is possible if the platform supports it, but population rules vary by system; consult the motherboard manual for approved rank combinations per channel.
