IBM 44V5183 server / storage / networking hardware Server Hardware / Parts

The IBM 44V5183 is a Memory Voltage Regulator Module rated at 95A, IBM CCIN 2A29, used on POWER6-based Power Systems servers. It converts the system’s main DC bus voltage down to the tighter, higher-current voltage that DDR2 memory DIMMs require, mounted directly on or adjacent to the memory riser it serves; VRMs of this class are matched to a specific memory technology and current draw, so a mismatched VRM can undersupply a fully populated memory riser even if it physically fits. This exact CCIN is documented consistently across multiple specialist IBM hardware resellers as a 95A memory VRM, distinguishing it from the general processor VRMs used elsewhere in the same server family. Genuine replacement VRMs of this CCIN are needed when a memory riser reports a voltage fault or when restoring full memory capacity after a VRM failure. Tech-Star (UK-based, shipped worldwide) supplies IBM Power Systems components to support ongoing server maintenance.
