Intel (R) C-STATE tech. Intel (R) C-STATE tech. is achieved by making the power and thermal control unit part of the core logic and not part of the chipset as before. Migration of the power and thermal management flow into the processor allows us to use a hardware coordination mechanism in which each core can request any C-state it wishes, thus allowing for individual core savings to be maximized. The CPU C-state is determined and entered based on the lowest common denominator of both cores' requests, portraying a single CPU entity to the chipset power management hardware and flows. Thus, software can manage each core independently, while the actual power management adheres to the platform and CPU shared resource restrictions. Configuration options are: [C2], [C3], [C4] and [Disabled]. The default value is [Disabled]. 3.4.3 Chipset Configuration BIOS SETUP UTILITY Advanced Chipset Settings Memory Remap Feature [Disabled] DRAM Frequency [Auto] Flexibility Option [Disabled] Standard Memory Info : 5-5-5-15-36-5-3-3-3 DRAM tCL [Auto] DRAM tRCD [Auto] DRAM tRP [Auto] DRAM tRAS [Auto] DRAM tRFC [Auto] DRAM tWR [Auto] DRAM tWTR [Auto] DRAM tRRD [Auto] DRAM tRTP [Auto] Advanced Memory Info : 18-18-4-4-0-0 DRAM CH0 RCOMP ODT [Auto] DRAM CH1 RCOMP ODT [Auto] DRAM CH0 tRD [Auto] DRAM CH1 tRD [Auto] ENABLE: Allow remapping of overlapped PCI memory above the total physical memory.

Memory Remap Feature Use this item to enable or disable memory remap feature. Configuration options: [Enabled] and [Disabled]. The default value is [Disabled]. DRAM Frequency If [Auto] is selected, the motherboard will detect the memory module(s) inserted and assigns appropriate frequency automatically. You may select [333MHz (DDR2 667)], [400MHz (DDR2 800)] or [533MHz (DDR2 1066)] for DDR2 memory modules, or select [533MHz (DDR3 1066)] or [667MHz (DDR3 1333)] for DDR3 memory modules. The configuration options depend on the CPU and memory module you adopt on this motherboard. Please refer to page 9 for the CPU FSB frequency and its corresponding memory support frequency. Flexibility Option The default value of this option is [Disabled]. It will allow better tolerance for memory compatibility when it is set to [Enabled]. 54
