At this moment, AMD family 10 series is equivalent to AM2+, and most CPU in this series are
Quad Cores. This option enables shutting down portions of the circuits in core when not in load,
it is a new feature of AM2+ CPU. This option will be displayed only if your CPU is supporting
this feature.
[Auto] : Enable entire cores, [Single Core] : Enable 1 core, Dual Core] : Enable 2 cores,
[Tri Core] : Enable 3 cores, [Quad Core] : Enable 4 cores.
Memory Timing Setting
► SLI-Ready Memory
Memory modules all have a programmable ROM chip that stores the SPD (Serial Presence
Detect) information. The function of SPD is to hold the performance capabilities of the memory.
This information is typically the optimal memory frequency and timings. Only one set of mem-
ory information can be stored on the SPD ROM because of JEDEC specifications. Developed
as an extension to the traditional Serial Presence Detect (SPD) found on today’s high-perform-
ance DIMMS, Enhanced Performance Profiles (EPP) allow memory manufacturers to integrate
additional module performance data in the unused portion of the JEDEC standard SPD, allow-
ing compatible motherboards to read and take advantage of added performance capabilities.
Enhanced Performance Profiles are useful for JEDEC specified modules as manufacturers
can have two predefined profiles for the memory modules—conservative and aggressive tim-
ings.SLI-Ready Memory settings become available when SLI-Ready/EPP memory modules
are detected by the BIOS. The settings include CPUOC 0% to CPUOC 13% and CPUOC
MAX. The various settings tells the BIOS the user wants to run the memory modules at the
higher speed, and it is alright to overclock the processor by the selected percentage. With the
selected option the BIOS will automatically drop the multiplier and increase the Hyper Trans-
port reference clock accordingly. The only thing the BIOS can’t do is adjust the CPU voltage so
if it goes too high you may run into stability problems if the CPU voltage isn’t increased. While
memory modules with Enhanced Performance Profiles will work on any motherboard, only
motherboards equipped with properly-designed BIOSes, such as those designed for NVIDIA
nForce® SLI media and communications processors (MCPs), will detect the presence of these
