Compatibility Focus

This 32GB kit targets administrators upgrading a Dell Powervault Nx3100 server with validated memory. The two 16GB DDR3L registered DIMMs carry ECC and run at 1.35V to match the platform’s low-voltage requirement. Computer Memory Solutions guarantees compatibility for the listed system. Buyers needing unbuffered ECC or consumer desktop modules cannot use this product.

Sustained Load Behaviour

Registered buffering and ECC correction keep data integrity stable during continuous server workloads. The modules operate at DDR3L 1333 with CL9 timing, though the platform may clock them to 1066MHz or 800MHz depending on the installed Xeon model and bank population. Quad-rank limits in the second triple-channel bank reduce speed to 800MHz. Mixing registered and unbuffered ECC is not supported.

Upgrade Context

The kit adds 32GB across two of the 12 or 18 available sockets, moving a configuration toward the 144GB or 192GB registered maximum. It replaces smaller registered DIMMs or fills empty slots in a bank that supports quad-rank modules. The jump is worthwhile when the workload demands ECC registered capacity beyond what unbuffered DIMMs can provide in the first two triple-channel banks per processor.

Questions about this item

How much power does each 16 GB DDR3L module draw at 1.35 V during continuous server operation?

Each module runs at 1.35 V, lower than standard DDR3, reducing heat output in a Dell Powervault Nx3100 running all day.

Does the Dell Powervault Nx3100 require registered ECC DIMMs or will unbuffered ECC work with this kit?

The system supports either registered ECC or unbuffered ECC, but mixing the two types is not supported; this kit provides registered ECC modules.

Will these 2Rx4 registered DIMMs run at 1333 MHz alongside older 1066 MHz DDR3 modules already installed in the Nx3100?

DDR3-1333 modules automatically clock down to 1066 MHz or 800 MHz depending on the Xeon model and how many banks are populated.
