Mystery accessory

It took some pondering to work out what this was for. I think I ''ve got it but would like to here all theories

Bios - Mother Board Intelligent Tweaker(MIT) & Advanced CPU Features Sub Menu
The MIT is the section where all overclocking is done. As all Gigabyte Intel products since ther P45 chipset, Gigabyte have a very extensive bios allowing us to change a wide range of timings, voltages etc.,

The X58 bios has an unusual layout, it has a "simple" main level and detailed sub levels for timings and voltages etc., This means that items often appear in both levels , which can be confusing and somewhat unnecessary.

Main Screen (top)

CPU Clock Ratio - CPU Multiplier

Advanced CPU Features - Sub Menu
Here we see the first repeated item CPU Clock Ratio, also available in the top menu, as mentioned above.

Intel(R) Turbo Boost Tech Allow Turbo to operate , by increasing Multiplier if available resource exists.

CPU Cores Enabled - Allows enabling of all or some cores

CPU Multi Threading - Leave at Default = Enable

CPU Enhanced Halt (C1E) Power saving function During System halt if enabled CPU core frequency and voltage is reduced.

C3/C6/C7/ State Support A power saving state similar to C1E above , but more enhanced. Default= Disabled

CPU Thermal Monitor Overheating protection - CPU frequency and voltage throttled back on reaching tjMAX

CPU EIST Function Enhanced Intel Speedstep Technology. Depending on CPU loading will reduce speed and voltage when CPU utilisation is low

Virtualization Technology Allows running multiple OS and applications in independent partitions.

Bi-Directional ProcHost
Enabled - Both CPU & chipset can detect and trigger PROCHOST signals to lower CPU performance and reduce heat generation.
Disabled - Only CPU triggers PROCHOST.

Default = Enabled

UNCORE & QPI Features Sub Menu

QPI Link Speed Quick Path Interconnect Architecture (QPI) provides the link between the CPU and IOH( Previously northbridge) See for more info.

Uncore Frequency Needs to be at least x2 Memory Multiplier - Would be nice to see this adjust automatically , but it doesn't so don't forget to adjust it if changing the Memory Multi.
Low

High

Isochronous Support
Determines if certain specific streams are enabled between IOH & ICH (Southbridge) . Default = Enabled.

Advanced Clock Controls

>>>Standard Clock controls<<<
1st 2 items repeated from Main Menu:-
Base Clock (BCLK) Control Enable to allow manual selection of BCLK

BCLK Frequency Mhz Select BCLK (Formally FSB on Socket 775)

PCI Express Frequency Mhz.
Low

High

C.I.A.2 - Automatic CPU overclocking control.

Quote:

Disabled Disables the use of C.I.A.2. (Default)
Cruise Increases CPU frequency by 5% or 7% depending on CPU loading.
Sports Increases CPU frequency by 7% or 9% depending on CPU loading.
Racing Increases CPU frequency by 9% or 11% depending on CPU loading.
Turbo Increases CPU frequency by 15% or 17% depending on CPU loading.
Full Thrust Increases CPU frequency by 17% or 19% depending on CPU loading.

Advanced Dram Features Sub Menu
The following features are in both the main and Advanced Dram features Menus.

Performance Enhance
Extreme Memory Profile (X.M.P.)
System Memory Multiplier (SPD)
DRAM Timing Selectable
Channel A~C:-
CAS Latency Time
tRCD
tRP
tRAS

Advanced Dram Features

Performance Enhance Standard = more stability at the expense of performance. Turbo = Balanced or average Stability Performance Extreme = Tightest timings best performance, less stable.

Extreme Memory Profile (X.M.P.) Enable = Ram uses the XPM timings from your memory's SPD chip.

System Memory Multiplier Ram speed = BCLK x Memory Multiplier. Ram Multiplier should be < Uncore Multiplier/2 (so remember to change Uncore (see Advanced Clock Controls Sub Menu)
Low

High

Dram Timing Selectable Select Enable to manually set memory Timings. Disabled = X.M.P if enabled (see above) or SPD.

Note: Voltages are colour coded in bios :
White = OK safe to use.
Pink = ok in short runs or with extra cooling. May have long term risk to components if overused.
Red = Use at your own risk, watch out for smoke
