System-specific DDR3 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR3 1600 PC3-12800 CL11 registered ECC modules on 240-pin DIMMs. It is built for Lenovo ThinkStation C30, D30 and S30 workstations that require registered memory with error correction. The modules run at 1.5 V and use a 2Rx4 organisation without heat spreaders.

Verify registered ECC support before ordering

Standard desktop motherboards cannot use registered ECC DIMMs and will not boot with them installed. Confirm that your ThinkStation model is C30, D30 or S30 and that the system BIOS is configured for registered memory. Do not mix these modules with unbuffered DIMMs or with any non-ECC memory already present in the system.

Replaces six Lenovo part numbers directly

The kit substitutes Lenovo parts 00FE676, 03T7754, 03T8399, 03X4378, 0A65734 and 0A89483, simplifying procurement for maintenance or capacity expansion. No additional software, cables or brackets are included; the upgrade consists solely of the four memory modules.
