MSI P67A-GD65 User Manual
After Intel launched the Series 50 chipsets
and Lynneld and Clarkdale processors for
desktops in 2009, platforms for LGA1156
processors have since become the focus of
worldwide power users. After another year
pf further research, Intel revolutionized again
the desktop platforms by launching the brand
new platform code-named Sandy Bridge,
which included both the Series 60 chipsets
and core processors. MSI thus launched the
next-gen Intel mainboards for consumers to
experience these new desktop products from
Intel.

OVERVIEW
New P67 Platform Weapon P67A-GD65 (B3)
For the new P67 mainboards, MSI also upgraded the OC Genie for P55
mainboards that has received critical acclaim to the OC Genie II. Along
with the brand new heat-sink design, the SATA III (6Gbps) interface
and USB3.0 ports to expand the mainboard capacity; and the militaryclass components, both the quality and lifespan of the P67 mainboards
have been enhanced.

Some OC Info About New
P67 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.

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.

NEXT GENERATION - OC GENIE II
MILITARY CLASS MATERIALS
Although Intel has imposed various OC restrictions on the Sandy Bridge
platform, the OC Genie button is still equipped on the mainboards for this
platform. In fact, it is the new-gen OC Genie II from MSI. Also equipped with
the auto optimization and quick hardware OC features, the OC Genie II can
automatically optimize the CPU Multiplier, CPU VCore, Memory Ratio and
Memory Voltage of Core i7/i5 processors for beginners to enjoy the greater
performance delivered by the Intel Turbo Boost in the simplest and fastest
manner.
OC Genie Button
It is easy to use the OC Genie. You just need to press the “OC
Genie” button when the system is shut off and the system will
auto overclock to its optimum status when rebooting.
Note:
The OC Genie II does not support Core i3 processors as a result
of the architectural restrictions of Sandy Bridge processors.

Continuing the premium-quality material design tradition, apart
from delivering a longer lifespan, the MSI P67A-GD65 (B3) mainboard makes OC operation more stable.
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.
