Platform
Despite design and architectural similarities between the Intel Series 60
chipsets for the brand new LGA1155 processors and the previous Series 50
chipsets for LGA1156 processors, none of them are compatible. In addition to
the integrated GPU, the Sandy Bridge is equipped with more demanding OC
restrictions. That is to say, it is less flexible than any LGA1156 processors.
OC : You need K SKU CPU
First, Intel has restricted base clock OC of
Sandy Bridge processors, and the average
BCLK OC range is about 10%. Given that the
default BCLK of the Sandy Bridge is 100MHz,
the OC range will fall within 110MHz. When
compared with the processors of previous
versions, the range is far less. In other words,
we can only adjust the CPU ratio (multiplier)
to run OC on the Sandy Bridge processors,
and the K series processors without ratio
block will surely be the primary choice for OC
power users.

Chipsets OC Limited
Apart from the range limit of processors, the design
of the Series 60 chipsets also differs. Although the
OC features of the P55 and H55 chipsets are similar
(depending on the mainboard design), it is necessary
for consumers to carefully select the Series 60 chipsets in order to run OC on their systems. Despite the
fact that the GPU is integrated with all Sandy Bridge
processors, users are advised to choose the K-series
processors and P67 mainbaords in order to exert the
power of OC. However, when one wants to run OC
on the GPU integrated with the processors, the H67
platforms will be the only choice. Simply speaking, it
is impossible to run GPU OC on the P67 platforms or
CPU OC on the H67 platforms.

Easy OC for Sandy Bridge ~ OC Genie II
MILITARY CLASS MATERIALS
Previously, MSI provided OC Genie to simplify overclocking for the P55
mainboards. Today, MSI’s Sandy Bridge boards feature the next generation OC Genie II. Since Sandy Bridge base clocks are now limited, the
new OC Genie II will take CPU ratio, CPU voltage, and XMP into consideration when overclocking various CPUs. With a press of a button, the
OC Genie II will overclock the CPU beyond what is possible with Intel
Turbo Boost.

Hi-C CAP
Hi-C CAP, HighlyConductive Polymerized Capacitor,
uses high electric
conduction polymer
as internal electrolyte,
featuring the small size
and high capacity, which
are commonly used in
many electronic products such as laptop computers, satellites and so on.
The main reason Hi-C CAP can be applied in high tech and precise machine is
that the special Core brings low ESR (Equivalent Series Resistance), low electric leaks (Leakage Current) and larger adaptation range of ambient temperature scope. High ESR and Leakage current cause not only unstable system
but also the life cycle reduction of spare part. The Hi-C CAP performance in
ESR and Leakage current both surpass the present mainstream Solid CAP,
not to say the obsolete EL CAP. Being as for the whole, Hi-C CAP stables the
motherboard power output, enhances the power transference efficiency
and has the adjustment function when Inrush Current (burst electric current)
occurs. Naturally, the power loss is extremely low, brings the greatest superiority either in overclocking operation or life cycle.
Once the
system is
shutdown,
depress the OC
Genie Button, and
the CPU will automatically be optimally overclocked. While it is possible
to disable OC Genie from the
BIOS or Control Center II, it is not
recommended.

SFC
To reach the lower power consumption, P67A-GD80 (B3)’s PWM adopt Green
Choke design, SFC (Super Ferrite Choke), utilizing the latest material technology - iron core. The material’s exclusive physical character allows SFC
automatically to adjust the inductance value for optimal power efficiency
based on the system’s loading. During light loading such as surfing the net
or running 2D operations, SFC can help provide up to a 20% improvement
in power efficiency compared to a normal ferrite choke. For heavier loading
such as playing 3D games, SFC’s ultra-low impedance still helps to maintain a
low operating temperature. Even when overclocking to the max, Super Ferrite Choke offers an incredibly stable supply of power. Clearly, SFC can satisfy
every possible power demand and usage scenario.
P67 with Multi-Graphics Cards
P67A-GD80 (B3) is equipped with three PCI-E x16 slots to support 3-Way
CrossFire as well as 2-Way SLI, allowing users to maximize their gaming experience with Nvidia and AMD graphics cards.

USB 3.0 has become the accepted standard for high-speed transfer. As a
response to the growing demand of USB 3.0, the P67A-GD80 (B3) breaks
through previous limitations by including two NEC USB 3.0 chips as well as a
VIA USB Hub chip to increase the number of USB 3.0 ports possible.
The P67A-GD80 (B3) has a VIA USB Hub chip in addition to the two NEC USB 3.0 chips. This combination increases the number of USB 3.0 ports on the
mainboard to ten.

OC NOTICE:
COOLER CONFIGURATION
Well-controlled temperature is sure to enhance overclocking capability. The
higher the CPU temperature rises, the higher risks of system instability and
overclocking failure may cause. According to our clinical test, temperature
of the boxed CPU fan of Intel may exceed 50 easily during OC usage due to
its small-scale cooling design. That is why changing a high-efficiency CPU fan
with better heat dissipation is recommend, radiation fan for instance, seems
to be a better solution for both of CPU and PWM. Furthermore, if you intend
to push your hardware to the limit, then CPU-LN2 would be the best choice
of all so far.

Manual OC Overview
Starting from the Sandy Bridge series, MSI will now adopt the new UEFI BIOS
as well as Click BIOS into its products. Previously, overclocking options were
listed in the “Cell Menu” those options can now be accessed by clicking on
the “Overclocking” picture.
Frequency Setting
Limitations of CPU base clock introduced by the Sandy Bridge series means
that there will only be a limited range of adjustment. Therefore, to overclock effectively, we will have to mainly increase the CPU ratio and leave CPU
base clock to make fine adjustments. The range of possible CPU ratios based
on the CPU will be reflected in the BIOS.
Note that the Memory Frequency adjustment is also limited by CPU base
clock. With the default 100MHz base clock, the possible memory frequency
are as follows: DDR3-800MHz, DDR3-1066MHz, DDR3-1333MHz, DDR31600MHz, DDR3-1866MHz, and DDR3-2133MHz. Any overclocking to the
memories will require adjustments to the base clock.
Voltage Setting
CPU Voltage, CPU IO Voltage (VTT), DRAM Voltage, System Agent Voltage,
and etc can be access in the “OC” options. The parameters relevant to CPU
overclocking are CPU Voltage and IO Voltage. The parameters relevant
for memory overclocking are DRAM Voltage and IO Voltage. In addition,
Internal PLL Voltage affects K SKU CPU’s overclocking ability; we recommend
turning on this option when overclocking. Important to note that the CPU
has built-in protections that will decrease CPU ratio if the CPU is too hot;
thus, when increasing the voltage, be aware that there may be circumstances
where more higher voltage may lower system performance.

Advanced Memory Timing Setting
After selecting DRAM Timing Mode, the Advanced DRAM Configuration
menu can be used to adjust memory settings. The left side shows the
memory’s default settings while the right side can be used to change the
memory’s timing.
OC Ability Reference
Now, taking the P67A-GD80 (B3) mainboard with the Intel’s latest Core i5
2500K CPU as an example, we will set Core Speed and Memory Frequency as
overclocking items to introduce some points and notices to users for reference.

CPU Feature
The CPU Feature menu can be used to adjust settings such as Execute Disable
Bit, Virtualization Technology, Power Technology, C-State, etc. The Long/
Short Duration Power Limit setting in particular can be used to adjust CPU
TDP wattage limit. These two settings will affect the processor when it is
under heavy load but will not affect CPU ratio.
Max CPU Core Speed
Previous platforms based on the P55 and X58 chipsets can overclock up to
about 4GHz~4.2GHz with air cooling. The unlocked ratio of the LGA 1155 K
SKUs allows the new CPU to overclock even further. K CPUs depend on CPU
ratio to overclock, while using base clock to make finer adjustments. CPU
voltage can be controlled with the VCore Voltage setting. CPU I/O voltage
should also be adjusted in with respect to base clock. In addition, changing
Vdroop voltage to Low Vdroop will increase stability for systems under heaving load. Extra care should be taken when using Low Vdroop, as voltage can
be erratic as well under heavy load.

Max Memory Frequency
Memory overclocking on the Sandy Bridge is limited by the Memory Ratio. Memory frequency can only be set to 800MHz, 1066MHz, 1333MHz,
1600MHz, 1866MHz, or 2133MHz.
In other words, the most stable memory overclock that can be achieved with
XMP is 2133MHz. To increase the frequency even further, the Memory Ratio
will need to be adjusted along with CPU base clock and voltage.
