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.

[. . . ] The key point of P45 Reference setting · CPU · CPU Vcore: 1. 429V ratio: x10 · DRAM Voltage: 1. 956V · MCH Voltage: 1. 304V · VTT FSB Voltage: 1. 3V 04 Invincible P45 Warrior 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.

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. 4-phase DrMOS P45 Neo2 built-in 4-phase DrMOS IC for PWM solution which is the best choice for overclocking and powersaving. Perfect Efficiency DrMOS IC is composed of Driver IC, Top MOS and Bottom MOS, offering amazing power conversion efficiency and low heat. 06 Invincible P45 Warrior Brand New: APS 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. 4-phase DrMOS P45 Neo2 built-in 4-phase DrMOS IC for PWM solution which is the best choice for overclocking and powersaving. CPU Vcore APS While system loading become heavier, then the APS LED itself will be AUTO adjusted depend on different loading percentage. 07 P45 Neo2 Overclocking Guide Brand New: EZ OC Switch EZ OC Switch is a hardware-based overclocking solution, it provides users an easy way to experience overclocking. With three different DIP settings, the system can easily get up to 20% additional performance. DIP switch Through EZ OC Switch, users could easily enjoy the fun of overclocking without any advanced BIOS adjustments. Adjustment method Through EZ OC Switch, you can easily get additional performance without any complex BIOS setting, particularly suitable for overclocking beginners. 08 P45 Neo2 Intel LGA775 P45 Neo2 2009MSIP45 10 P45 Neo2 11 Cell Menu 12 14 : DrMOS 15 : APS 16 : EZ OC Switch 09 P45 Neo2 P45 Neo2 P45 Neo2 MS-7577 v1. 0 I/O 4DrMOS APS DDR2 PCI Express x16 CrossFire ALC888 6+2 SATA LED (P45 Neo2-FIR) 10 P45 Cell Menu Cell Menu Cell Menu DRAM Intel P45MSI RDP45 Neo2Cell Menu CPU ClockGen TunerCPU DRAM DRAM 11 P45 Neo2 P45 Neo2P45 DiamondP45 / P45 Neo2 BIOS CPU HDD PSU OS MSI P45 Neo2 v. 1. 0 v. 120 Core 2 Quad 9650 Extreme Edition/Core 2 Duo E8400 Corsair CM2X1024-10000C5D ATI Radeon HD4870 512MB Western Digital VelociRaptor WD3000HLFS, 300GB/SATA Ikonik GAIA 500W 80Plus Windows Vista SP1 CPU P45 Neo24. 1GHz QX9650P45 Neo2 · CPU: · CPU: 1. 429V x10 · DRAM: 1. 956V · MCH: 1. 304V · VTT FSB: 1. 3V 12 P45 MCHVTT FSB FSB MCH1. 4~1. 45V CPU FSB CPU FSBCPU Core 2 Duo E8400CPU x6 FSB 540MHzCPU FSB CPUMCH 1. 5083V 540MHz · CPU: x6 · DRAM: 1. 992V · MCH: 1. 388V · VTT FSB: 1. 38V · FSB: · CPU: CPUMCH CLK Skew CPU FSB 13 P45 Neo2 : DrMOS DrMOSP45 Neo2 Driver ICTop MOSBottom MOS 90%P45 Neo2 4DrMOS P45 Neo24 DrMOS ICPWM DrMOS ICDriver ICTop MOSBottom MOS 14 P45 : APS APS"Active Phase Switching"MSI P45 Neo2CPUAPS BIOSAPS PWM IC APS4 50%2/3 4DrMOS P45 Neo24 DrMOS ICPWM CPUAPS APS LED 15 P45 Neo2 : EZ OC Switch EZ OC Switch DIP 20% DIP EZ OC Switch BIOS EZ OC SwitchBIOS 16 P45 Neo2 Intel LGA775 . . 18 P45 Neo2 19 20 22 : DrMOS 23 : APS 24 : EZ OC Switch 17 P45 Neo2 P45 Neo2 P45 Neo2 .
