Lenovo ThinkSystem C527 16GB TruDDR5 5600MHz ECC UDIMM - 16 GB RAM - DDR5-5600/PC5-44800 TruDDR5 - 5600 MHz Single-rank Memory - 288-pin - DIMM

The Lenovo ThinkSystem C527 is a 16GB DDR5-5600 ECC UDIMM for users upgrading a compatible desktop or workstation that requires 288-pin ECC unbuffered memory.

Recommended For

• Operators upgrading a Lenovo ThinkSystem ST50 V3 or SR250 V3 for a small-office file, print, or application server: Lenovo lists this exact 16GB ECC UDIMM as a supported memory option for both models.
• Administrators maintaining an ECC-capable server who need a replacement or added memory module and have confirmed their system supports Lenovo part 4X77A99751; this is a 16GB DDR5-5600 ECC UDIMM, not a registered DIMM.
• ST50 V3 or SR250 V3 owners building a modest ECC memory configuration with matched modules; Lenovo specifies identical DIMMs for these systems, so check the system’s supported configuration before mixing modules.

Real-World Use Scenarios

• When an ST50 V3 needs more memory for small-business services, adding a matching C527 module can increase available capacity; check the server’s DIMM population rules before installing it.
• For a compatible ST50 V3 running shared business applications, ECC memory can help correct certain memory errors, reducing the risk of interruptions associated with those errors.
• When setting up a supported ST50 V3 for a lightweight virtualization lab, this DIMM contributes memory for the host and virtual machines; the workload still needs to fit within the server’s total installed RAM.
• If an ST50 V3 reports a memory fault, using this listed Lenovo memory option as a compatible replacement can restore the supported DIMM configuration after the faulty module is replaced.
• For a small or branch-office server used for routine business workloads, installing C527 memory in a supported ST50 V3 provides a Lenovo-qualified ECC memory option; it is not a general-purpose desktop-memory upgrade.
