요런거 나오면 바로 적용

UEFI를 2012년 2쿼터에 발표한다고 하네요 요걸 적용해야하는데

안나왔다면 아래 방법으로

Workaround 1

Revert the server to third quarter 2011 UEFI, IMM, and Field Programmable Gate Array (FPGA) code levels as shown below. With these levels, the error may be ignored with minimal impact to performance.

UEFI v1.71a g0e171a
IMM v1.30 yuooc7e
FPGA v2.01 g0ud72b

Workaround 2

After applying Workaround 1, change the QPI link speed to Power Efficiency from Maximum Performance as follows:

F1 Setup --> System Settings --> Operating Modes --> QPI Link Frequency --> Power Efficiency

두가지 방법이 있다고 하니 요대로 적용
