[German]Cisco has issued a warning for memory chips (DIMMs) that are likely to be used in its own products, such as the Cisco Unified Computing System (UCS). A limited number of Cisco-supplied DIMMs manufactured in the mid-to-late 2020s are prone to early failures due to a manufacturing issue. For most DIMMs, ECC error correction can fix these memory errors. However, an uncorrectable memory event may occur at some point. If this occurs at runtime, uncorrectable memory errors will cause a sudden unexpected server reset. If the errors occur during the power-on self-test (POST), the DIMM module is blanked and the total available memory is reduced. In some cases, a boot failure may occur. 16GB, 32GB and 64GB DIMMs from certain batches are affected. Cisco provides a tool to identify the modules, which are then to be replaced. (via)
