8GB DDR4 2400 ECC SODIMM

This 8GB DDR4 2400 ECC SODIMM module delivers error-correcting memory for compatible laptop or compact server platforms. It operates at 2400MHz with CL17 latency and standard 1.20V power. The unbuffered design suits systems that require ECC without registered signalling. Builders upgrading a Samsung M474A1G43DB1-CRC or M474A1G43EB1-CRC module can use this as a direct replacement.

260-pin SO-DIMM fits DDR4 slots

The 260-pin SO-DIMM form factor installs in any DDR4 SO-DIMM slot wired for unbuffered ECC memory. No extra power cables or cooling brackets are required. The single 8GB rank leaves additional slots free for further capacity expansion if the platform supports it. Verify the system documentation for maximum supported memory and ECC enablement before installation.

Sustained workloads benefit from ECC

Error correction detects and corrects single-bit errors during continuous operation, reducing silent data corruption in long-running tasks. The module maintains its 2400MHz CL17 timing under sustained load at the rated 1.20V. Systems without ECC support in the memory controller will not activate the protection, so confirm platform compatibility to gain the reliability advantage.

Questions about this item

Will the CL17 latency throttle throughput during sustained server workloads?

The module runs at DDR4 2400 with CL17 timings; latency stays fixed at that rating and does not increase under continuous load.

Does the 1.20 V ECC SODIMM run hot or draw extra power in a 24/7 workstation?

Standard DDR4 1.20 V operation keeps power draw and heat at typical SODIMM levels even during all-day ECC workloads.

My laptop only takes non-ECC memory — will this 260-pin ECC module still work?

This is an ECC unbuffered SODIMM; it requires a platform that explicitly supports ECC SO-DIMMs, so a non-ECC-only laptop will not accept it.
