MSSQLSERVER_41342

Details

Product Name SQL Server
Event ID 41342
Event Source MSSQLSERVER
Component SQLEngine
Symbolic Name HK_HW_NOT_SUPPORTED
Message Text The model of the processor on the system does not support creating construct. This error typically occurs with older processors. See SQL Server Books Online for information on supported models.

Explanation

Memory-optimized tables require a processor model that supports atomic compare-and-exchange operations on 128-bit values, which require the assembly instruction CMPXCHG16B. Certain older AMD processor models do not support the CMPXCHG16B instruction. Also, certain virtualization environments do not enable this instruction by default.

User Action

Upgrade your processor. If your processor supports the instruction and you are running SQL Server in a virtual machine, change the configuration to support the instruction CMPXCHG16B.
