P45 Neo2 Overclocking Guide
Following Intel official strategy of desktop platform, LGA775architecture processor is still the mainstream product line in the
channel market. P45 Neo2 is a price-competitive mainstream
model which is positioned to high-performance and high economical product.
Entered in 2009, MSI is taking energy-saving seriously and looking forward to establish a new landmark with P45 Neo2 in P45
segment market.
We produce the overclocking guide aimed to provide users
a more detailed and precise overclocking information for the
smooth achievement of objectives and enjoy the fun of overclocking.

Although P45 Neo2 is defined as the price competitiveness mainstream
models, but has amazing performance and practicality. This includes excellent overclocking performance, and emphasizes on energy conservation
by a sign of high power efficiency, and even provides the vast majority of
players who want to expand the capacity.

Basically, Cell Menu is designed for overclocking. Through Cell Menu, overclockers could tweak detailed system configuration, like core component voltage or
DRAM timing and so on. Besides, according to the characteristic of Intel P45
platform, MSI RD team enhanced the Cell Menu for P45 Neo2 and try to fulfill
every kind of overclocking demand.

CPU-related adjustment items, whether
simple performance output, or trying
overclocking, here are completed function for overclockers to adjust options.
In order to achieve the best memory
performance, users can complete the
relevant option and make appropriate
adjustments. These include timing delay,
operating frequency.
ClockGen Tuner is the key point of CPU
overclocking. Which could tweaking the
signal skew rate and making overclocking
more smoothly.

items, offering complete option and
range for chasing highest overclocking.
Shorter DRAM delay timing could get
better performance but lengthen DRAM
timing would benefit for overclocking.
Or, you can manually adjust the timing
delay of the memory.

In general, P45 Neo2 is a high performance/value segment model in the
channel market, even though it didn’t equip with full feature like P45
flagship model such as P45 Diamond. But P45 Neo2 still has outstanding
overclocking ability. The below is a demonstration system as an overclocking
example of P45 Neo2.

Neo2 overclocking are both of MCH and VTT FSB voltages, and appropriate
voltage setting could benefit the system overclocking. For example, raising the
MCH voltage up to 1.4~1.45V is an ideal range while you chase extreme FSB
frequency.
Max CPU FSB frequency
For chasing highest CPU FSB frequency, generally we suggest to decrease the
CPU multiplier. Taking Core 2 Duo E8400 for example, setting CPU multiplier
as x6 would be better and easier way to touch its limitation. With Core 2 Duo
E8400, its FSB frequency could overclock up to 540MHz under air-cooling
configuration. The key point of chasing max CPU FSB frequency would be the
CPU and MCH clock skew. Appropriate clock skew would help overclocking
more smoothly.

Next-generation DrMOS technology is the key power efficiency function of
P45 Neo2. Combined with Driver IC, Top MOS and Bottom MOS, DrMOS
provide the best power conversion-efficiency up to 90% or above. With its
characteristic, P45 Neo2 provideing lower impedance and shorter power
react timing which is benefit for not only harsh overclocking usage but
also dynamic power-saving.

APS is abbreviation for “Active Phase Switching”, which is the unique
energy efficient solution made by MSI. P45 Neo2 provides APS function in
CPU Vcore side, it could be controlled under BIOS. APS was implemented
by additional circuit from PWM IC, and it would switch the phases automatically by detecting system loading.
For example, when system is under full loading, APS would switch to
4-phase control and if only 50% or lower loading, it would switch to 2 or
3-phase control.

While system loading become heavier, then the APS LED itself will be AUTO adjusted
