Server-grade DDR3L 64GB kit

This 64GB kit contains four 16GB DDR3L 1333 ECC Registered RDIMM modules built for Cisco UCS B230 M2 and C260 M2 servers. The modules run at 1.35V with CL9 latency and a 2Rx4 rank configuration. They are designed for workstation and server platforms that require registered ECC memory.

Sustained-load behaviour

Registered buffering and ECC correction keep data integrity stable during continuous multi-threaded workloads typical of virtualization hosts or database servers. The lower 1.35V operating voltage reduces thermal output compared to standard DDR3, helping maintain consistent throughput in densely populated memory channels over long periods.

Pre-order checklist

Verify that your system explicitly supports DDR3L 1333 ECC Registered RDIMMs and cannot accept unbuffered or load-reduced DIMMs. Confirm the motherboard has four available 240-pin slots and that the BIOS recognises 16GB density modules per slot. Mixing with non-registered memory will prevent boot.

Questions about this item

How much power does the 1.35 V DDR3L kit draw under continuous load?

Each module runs at 1.35 V, lower than standard DDR3, reducing power draw and heat during all-day operation in Cisco UCS B230 M2 or C260 M2 servers.

What must the system already have to accept these 240-pin registered DIMMs?

A Cisco UCS B230 M2 or C260 M2 with free 240-pin DDR3L slots that support ECC registered memory; it will not work in standard desktops or with unbuffered or load-reduced modules.

Can the 2Rx4 CL9 modules share channels with existing Cisco A02M316GB1L or UCSMR1X162RXA parts?

Yes, they replace Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC, so they can populate the same server platforms.
