The IBM 00RR681 is a Memory Buffer VRM (voltage regulator module), CCIN 6B33, which regulates the power rail feeding the Centaur memory buffer chips on IBM Power System E870, E880 and S824 (Power8) servers. The Centaur chip sits between the POWER8 processor and the physical DIMMs, buffering and caching memory traffic, and needs its own dedicated, tightly-regulated voltage supply separate from the processor and DRAM rails – which is what this card provides. Independent listings confirm this exact part number against CCIN 6B33 for the E870/E880 platform. As with the rest of the Power8 CEC VRM family, it is an individually swappable field part. Tech-Star supplies this as a pull from decommissioned Power8 systems, ready to restore memory-buffer power redundancy on a compatible installation.
