今天遇到一个问题是服务器上BIOS检查DIMM出现错误：
462-Uncorrectable Memory Error Threshold Exceeded(Processor 1, DIMM 14). The DIMM is mapped out and is currently not available. Action: Take corrective action for the failing DIMM. Re-map all DIMMs back into the memory in RBSU.

这个错误的提示非常的明显了，就是DIMM-14有不能改正的错误，需要做RBSU里做re-map。
做了之后就好了。
