Lenovo ThinkSystem ECC UDIMM

This 8 GB DDR4 3200 module is built for Lenovo ThinkSystem servers and workstations that require ECC unbuffered memory. It targets IT professionals and system builders who need validated compatibility with Intel processor based platforms. The single-rank design keeps electrical loading low for stable operation in multi-slot configurations.

Verify DDR4 ECC UDIMM support

Confirm that your motherboard accepts 288-pin DDR4 ECC unbuffered DIMMs and can run at 3200 MT/s with CL22 latency at 1.20 V. Check the system documentation for maximum capacity per slot and total population rules before ordering. Ensure the platform BIOS is current to avoid training issues with this speed grade.

Single module frees remaining slots

The 1Rx8 organisation leaves additional DIMM sockets available for future expansion without exceeding rank limits per channel. No heat spreader is fitted, so clearance is minimal in dense chassis layouts. The module draws standard DDR4 voltage, simplifying power budgeting for memory-heavy deployments.

Questions sur cet article

Does the package contain only the single 8GB DDR4 3200 ECC UDIMM module, or are additional components included?

The package contains one 8GB DDR4 3200 ECC UDIMM module (1Rx8, CL22, 1.2V, 288-pin). No extra cables, brackets or heat spreaders are supplied.

Should I choose this 8GB 1Rx8 CL22 module or a different capacity or rank for my Lenovo ThinkSystem server?

Select this 8GB 1Rx8 CL22 module when your ThinkSystem requires DDR4 3200 ECC UDIMM memory matching part number 4X77A77494. Other capacities or ranks may not be validated for that system.

What does the 3200 MT/s rating mean once the module is installed in a compatible Lenovo server?

In a supported ThinkSystem the module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, delivering the rated bandwidth and ECC error correction for the platform.
