MSI P67A-GD65 (B3) Intel official boxed CPU fan, Better to use enhanced cooler set, Overclocking

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.

Intel official boxed CPU fan	Not recommend
This is the original boxed LGA1155 CPU
fan, and it’s not suitable for overclocking
due to its small-scale cooling design.

Better to use enhanced cooler set	Acceptable
The dissipation effect of the enhanced
cooler set is better than that of the origi-
nal factory fan.

The special design cooler set of	Better
overclocking

It takes the illustrated proprietary design cooler set to lower temperature and avoid system instability.

MANUAL OC OVERVIEW

All MSI Sandy Bridge mainboards are equipped with the latest UEFI BIOS technology, and the OC setup items are mostly found in the OC option in the main menu. Regardless of the differences in the user interface, both the name of options and the setup procedure of these options are similar to those of the previous MSI mainboards. Therefore, it is very easy for users to adapt to them.

Frequency Setting

Due to the Base Frequency restrictions of the Sandy Bridge processors, us- ers are advised to adjust the CPU Ratio while running frequency-related OC operations, while CPU Base Frequency is supportive. For example, when running memory OC, users can fine-tune the memory from DRAM Ratio. It is noteworthy that the unit for the Base Frequency is 10KHz.

Also, users were advised to shut down the Intel Turbo Boost when running OC manually. On the Sandy Bridge processors, however, users are advised to turn the Intel Turbo Boost in order to obtain the unexpectedly great OC effect.
