Server memory upgrade

This 128GB kit contains four 32GB DDR3L 1600 CL11 registered DIMMs built for Dell PowerVault DX6104, DX6112 SN, NX3200 and NX3300 systems. The modules operate at 1.35V and provide ECC error correction for data integrity in server and NAS workloads. They are not compatible with standard desktop computers or unbuffered memory configurations.

Sustained workload behaviour

ECC registered architecture detects and corrects single-bit errors during continuous operation, helping maintain data accuracy across long backup or virtualization tasks. CL11 latency at 1600MHz delivers consistent throughput for multi-threaded server applications. The 4Rx4 organisation supports high-density population across all available slots.

Build and connectivity

Each 240-pin DIMM follows JEDEC and RoHS standards without a heat spreader, allowing tight spacing in dense chassis. Registered buffering reduces electrical load on the memory controller when all four modules are installed. The kit is designed as a warranty-safe upgrade that meets OEM specifications for the listed PowerVault models.

Questions about this item

How much power does the 1.35V DDR3L kit draw when the server runs continuously?

Each 32GB module operates at 1.35 volts, lower than standard DDR3, so the four-module kit reduces overall power draw and heat output during all-day operation.

Which Dell PowerVault models must I already own for this 240-pin RDIMM kit to work?

The kit is validated for Dell PowerVault DX6104, DX6112 SN, NX3200 and NX3300; the system must accept 240-pin DDR3L ECC registered DIMMs.

Can I mix these 4Rx4 registered modules with any unbuffered DIMMs already installed in my PowerVault?

No — the modules are ECC registered (4Rx4) and cannot be mixed with unbuffered memory; all slots must use registered DIMMs for the system to function.
