32 GB DDR3 1600 ECC Kit

This 32 GB kit contains four 8 GB unbuffered DDR3 DIMMs rated at 1600 MHz with CL11 latency and 1.50 V operation. It targets servers and workstations that require error-correcting memory for data integrity.

DDR3 1600 Interface Limits

The DDR3 1600 standard tops out at 1600 MT/s and 1.50 V, so bandwidth and voltage headroom are fixed by the specification. Unbuffered ECC modules add error detection without the latency penalty of registered designs, but they still require motherboard support for ECC and 240-pin DDR3 slots.

32 GB Capacity Headroom

Four populated slots deliver 32 GB total, a practical ceiling for many dual-channel DDR3 platforms that max out at four DIMMs. Larger datasets or heavier virtualisation workloads will exceed this capacity, requiring a platform that accepts higher-density modules or more memory channels.

Questions about this item

Should I choose the 32 GB kit or a different capacity for my server?

This kit provides 32 GB total across four 8 GB modules; select it when your board has four slots and you need that exact capacity.

What does 1600 MHz with CL11 mean for actual server workloads?

The modules run at 1600 MHz DDR3 with CL11 timing, giving consistent throughput for ECC-protected tasks such as virtualization and database caching.

How does the 240-pin DDR3 interface limit performance in practice?

The 240-pin DDR3 interface caps transfer rates at the 1600 MHz specification, so bandwidth cannot exceed what this generation defines.
