Configuration options: [CLTT] [OLTT] [Disabled] [Auto] Selecting CLTT forces the BIOS to enable CLTT throttling mode Selecting OLTT forces the BIOS to enable OLTT throttling mode Selecting Disabled configures the BIOS not to implement memory throttling on the system. Selecting Auto allows the BIOS to determine which memory throttling mechanism to support. If BIOS detects that the installed DIMMs have the necessary thermal sensors, then CLTT will be enabled. If BIOS detects that the installed DIMMs have faulty or missing thermal sensors, then OLTT will be enabled. When the Memory Thermal Throttling option is set to any setting except [Disabled], the following additional options displays on the screen: Intel® Server System SR1670HV Service Guide 63
