Targeted Lenovo Workstation Upgrade

This 8GB kit contains two 4GB DDR3L modules built for Lenovo ThinkStation S20 and ThinkServer TS140 systems. It suits administrators who need ECC protection on Xeon platforms without registered buffering.

Low-Voltage Stability

Operating at 1.35V, the unregistered DIMMs reduce power draw compared to standard DDR3 while maintaining CL11 timing at 1600MHz. The modules automatically clock down to 1333MHz, 1066MHz or 800MHz depending on the installed Xeon model and population order.

Matched Pair for Triple-Channel Boards

The two-stick package lets you populate a single bank of three sockets; maximum capacity reaches 24GB across six slots when kits are combined. Mixing these unbuffered ECC sticks with registered ECC modules is not supported by the platform.

Questions about this item

How do I install the two 4 GB DDR3L 1600 modules in a Lenovo ThinkStation S20, and which step is most often missed?

Populate all three slots of a memory bank with identical modules to enable triple-channel mode; the common mistake is installing only one or two sticks per bank.

What maintenance or replacement will this 8 GB DDR3L ECC kit need later?

No routine maintenance is required; replace modules only if memory diagnostics report correctable ECC errors that exceed the platform threshold.

What limit appears first when this DDR3L 1600 kit runs sustained workloads in a ThinkStation S20?

The Xeon memory controller down-clocks the modules to 1066 MHz or 800 MHz depending on the processor and population, capping sustained bandwidth.
