ECC SODIMM kit for workstations

This 16 GB kit contains two 8 GB DDR4 SO-DIMM modules rated at 2933 MHz with CL21 latency. ECC unbuffered operation adds single-bit error correction for data integrity. The 1.2 V modules suit mobile workstations, microservers and NAS appliances that require 260-pin DDR4 ECC memory.

Steady throughput with error correction

ECC circuitry detects and corrects single-bit errors during sustained workloads, preventing silent data corruption in long-running tasks. Unbuffered design keeps latency low while the dual-channel kit populates both slots for balanced bandwidth. JEDEC-standard 1.2 V power draw remains stable under continuous load.

Single-rank x8 organisation

Each module uses a 1Rx8 layout, a key factor for compatibility with platforms that limit rank population per channel. Verify your system's qualified-vendor list for 260-pin DDR4 ECC SODIMM support before purchase. Modules lacking this rank structure may not post in restricted configurations.

Questions about this item

How much power does the 1.2V DDR4 2933 kit draw under continuous load?

The modules run at 1.20V JEDEC standard voltage, so power draw stays at the DDR4 baseline for 2933 MHz CL21 operation.

Does my laptop need an ECC-capable SO-DIMM slot to use this 260-pin kit?

Yes — the system must support DDR4 ECC unbuffered SO-DIMM; standard non-ECC slots will not enable the error-correction function.

Will these single-rank 1Rx8 sticks work alongside older dual-rank DDR4 SODIMMs I already have?

Mixing ranks is possible if the platform allows it, but the memory controller will run all modules at the lowest common speed and timings.
