Server ECC Upgrade for ThinkServer TD230

This 8 GB kit contains two 4 GB DDR3 1333 MHz registered ECC DIMMs built for the Lenovo ThinkServer TD230. The modules run at 1.5 V with CL9 9-9-9 timings and use a 240-pin form factor. They are designed for server workloads that require error-correcting memory.

Replaces Non-ECC or Lower-Capacity DIMMs

Swapping standard unbuffered memory for these registered ECC modules adds data-integrity protection and enables the platform's full 32 GB ceiling across eight slots. The upgrade is worthwhile when the TD230 is used for virtualisation, database work or any task where silent data corruption is unacceptable.

Fits Eight-Slot TD230 Configurations

Each CPU in the TD230 provides four DIMM sockets; this two-stick kit occupies one channel per processor or both sticks on a single CPU. The registered design reduces electrical load on the memory controller, freeing headroom for populating all eight slots without signal-degradation issues. No heat spreaders are fitted, so airflow clearance is minimal.

Questions about this item

Will these 240-pin DDR3 modules fit the eight DIMM slots in a Lenovo ThinkServer TD230?

Yes, the kit is validated for the TD230 and its eight sockets, four per CPU, so both 4 GB sticks install directly.

What is the correct order for seating the two registered ECC sticks during installation?

Populate the lowest-numbered slot on each CPU first, then add the second stick to the matching channel; skipping a slot leaves the rank unrecognised.

When should the 1.5 V registered DIMMs be replaced if ECC error counts start rising?

Replace them once corrected-error logs show a sustained upward trend, typically after several years of continuous server duty.
