DrMOS

In order to provide customers stable and high quality products, starting from P45 series motherboards, MSI is leading the industry to introduce the world's most advanced power supply component, DrMOS (Driver-MOSFET), which integrates Driver IC, Top MOSFET and Bottom MOSFET into one chip. Except for its outstanding performance in power saving, DrMOS possesses switch frequency which is 400% faster than traditional MOSFET and has great improvement in stabilizing power supply and voltage control. Even under heavy loading and overclocking conditions, DrMOS can still provide the most stable and efficient power supply and quality.

Unlock CPU Core

MSI’s Unlock CPU Core technology, exclusive from MSI, can unlock the hidden cores in the CPU by making a few selections from the BIOS. By unlocking a Phenom II X2 CPU into a Phenom II X4 CPU, users can boost the CPU performance over 104%. In Addition, MSI discovers the ability to unlock Phenom II X4 960T to a 6 core CPU through the same BIOS setting. At same time, MSI was the first who could unlock a 4-core AMD CPU to a 6-core because MSI does not use any "unlock" chip on our motherboards. MSI engineers developed a BIOS technology to unlock cores which can be easy upgraded via new BIOS. Because of this flexible BIOS core unlock feature, MSI can today announce that it made BIOS unlocking easy and accessible for the audience who doesn’t know their way around the BIOS. This new MSI software tool allows users to unlock CPU cores from Windows with just a few simple clicks, no need to enter the BIOS.

Easy OC Switch

Every user desires more performance.  MSI has special Easy OC Switches to provide that accessibility to all users. This great technology makes it easier to tweak the core clock settings. There's no need to have a detailed understanding; with just a few simple steps, everyone is able to get the most out of their motherboards. With a single click, the whole system will increase by 5%-20% performance, making overclocking a very easy thing to do.

All Solid Capacitors

Capacitors are the most important component for electronic product's power supply. The quality of the capacitors can impact the stability of the entire system and risk of product failure. Currently there are two types of capacitors, electrolytic capacitors and solid capacitors. Compared to electrolytic capacitors, solid capacitors have a longer lifespan, and provide a more stable power under high temperatures. More importantly, solid capacitors do not have any liquid materials inside, and thus will not suffer a leak which would infringe upon the product’s stability. With such benefits is it no wonder that solid capacitors are very important for product quality's improvement.
