What does MCi_STATUS MSR = 0x00000000BE000000000000000100110B and MCi_STATUS MSR = 0x00000000BE000000000000000100117B mean?

I have encountered two BSODs (bug check 0x124) on two different devices using Intel Celeron 3765U @ 1.9 GHz.

Additional parameters provided by the bug check:

1. 0, 0xFFFFFA800532A038, 0xBE000000, 0x100110B

2. 0, 0xFFFFFA800530C038, 0xBE000000, 0x100117B

Have created a support ticket at Microsoft and support engineer asked me to check contents of the MCI_STATUS MSR with Intel.

So here it is:

1. MCi_STATUS MSR = 0x00000000BE000000000000000100110B

2. MCi_STATUS MSR = 0x00000000BE000000000000000100117B

Additionally a support engineer at Intel already opened the case# 02812568.

Is it possible to gain more information from the contents of the MCI_STATUS MSR?

Thank you very much in advance.

BR,

Matthias

Hi Carlos,

It looks to me like Cache Hierarchy Errors with unknown transaction type and hierarchy level (one is cache eviction error).

My understanding is family=6 and model=0x3D for Celeron 3765 U @ 1.90 GHz (Dual Core) but I could not find a section in chapter 16 for this CPU to interpret the model specific error code (0x0100). Is there a separate Software Developer's Manual for this architecture?

Best Regards,

Gary
