System-Specific DDR3 Kit

This 32 GB kit contains four 8 GB unbuffered ECC DIMMs built for the Lenovo ThinkServer TS430. It targets administrators who need the full 32 GB capacity across the server’s four memory sockets. Buyers who want more storage or non-ECC modules should look elsewhere.

Compatibility Check

Verify that your ThinkServer TS430 carries a manufacturing part number in the 0387, 0388, 0389, 0390, 0391, 0392, 0393 or 0441 series. The server must accept 240-pin DDR3-1600 modules at 1.5 V with 2Rx8 organisation. Systems requiring registered DIMMs or a different pin count will not accept this kit.

Sustained Load Behaviour

Each module runs at CL11 11-11-11 timings without a heat spreader, so airflow through the chassis determines temperature stability. ECC correction operates continuously during long compute runs, maintaining data integrity across all four populated sockets.

Questions about this item

Does the B90 kit include anything besides the four 8 GB DDR3-1600 modules, or do I need to buy extra parts?

The box contains only the four 240-pin ECC unbuffered DIMMs; no cables, brackets or tools are included and none are required for installation in a ThinkServer TS430.

Should I choose the 32 GB B90 kit or a smaller capacity for my TS430?

The TS430 has four memory sockets and a 32 GB maximum, so this 4 x 8 GB kit fills every slot and reaches the system limit in one purchase.

What does the DDR3-1600 CL11 1.5 V rating mean once the modules are installed in the TS430?

The memory will run at 1600 MHz with 11-11-11 timings at the standard 1.5 V, delivering the rated PC3-12800 bandwidth for server workloads.
