M5A99FX PRO Overview

Overview

 

Dual Intelligent Processors 3 with New DIGI+ Power Control

6+2+2 Phase DIGI+ Power Control for CPU and DRAM

The Digital revolution continues in the 990FX platform with the expansion of the DIGI+ Power Control beyond the CPU VCore. In the latest ASUS 990FX R2.0 motherboards, the DRAM Voltage get precise power control as well through a new inclusive Digital Power Design. With DIGI+ Power control over the DRAM, the overclocking adjustment possibilities increase exponentially and configurations that were once impossible are now achievable. All of these are adjustable through the UEFI BIOS or through the AI Suite.

6+2 Phase DIGI+ Power

EPU and SMART DIGI+

ASUS M5A99FX Pro R2.0 has an embedded energy-optimization microprocessor that works in conjunction with the DIGI+ VRM to achieve high energy efficiency. The EPU can be enabled or disabled via an onboard switch or through software, giving the user flexible options for adjusting the power saving features when necessary. With the capability to detect the accurate CPU load in real time, by interpreting the current consumption of the CPU, EPU intelligently manages the balance between performance and power consumption, delivering an unbeatable performance per watt ratio, as compared to competing solutions. The EPU is connected directly to the CPU to detect the exact CPU loading, and control active power phase, voltage and multiplier in real time.

TPU

A second microprocessor, dedicated for automatic system tuning, is embedded in the ASUS M5A99FX Pro R2.0 called TPU. The system automatically adjusts settings to an overclocked and stable state. This feature is also accessible in software mode through ASUS TurboV EVO easy overclocking tool for a single-click auto-system level up. The TPU not only allows a finer configuration of voltage control beyond the ability of any existing controllers, the real-time detection of the exact voltage reading are also made available through it. This is especially essential for overclocking purposes, ensuring the added on voltage can be minimized, whether it is for manual or automatic overclocking purposes. The TPU is connected to both the SMBUS and the CPU directly, to control the behavior of the rest of the system.

 

Dual Channel DDR3 up to 2400MHz with Q-DIMM Design and MemOK!

In case a memory error occurs during overclocking, the Mem OK! Button allows the adjustment of memory settings to a more acceptable state, whether the error was because of a voltage or memory timing issue. This ensures maximum working compatibility for the memory when overclocking without resorting to a CMOS reset.For convenient DIY installation, ASUS has also equipped their motherboards with the single locking Q-DIMM design for an unobstructed memory module installation without uninstalling the video card on the top most PCI-E x16 slot. With the latest BIOS update, 2133MHz and 2400MHz DDR3 memory are also now supported.

Fast SATA3 6G Ports with eSATA 6G

ASUS provides two extra SATA 6Gb/s ports on the ASUS M5A99FX Pro R2.0 through a dedicated ASMedia 1061 chipset, providing high bandwidth transfer rates without bottlenecking PCI Express performance. Combined with the SATA 6Gb/s natively supported in AMD SB950, the ASUS M5A99FX Pro R2.0 offers unparalleled connectivity options for users who want maximum performance out of their drives. One of the SATA3 6G Ports from the AMD SB950 provides hot-swap functionality for external drives.

USB 3.0 Ports with UASP Support and AiCharger+

With the introduction of providing both the front and rear USB 3.0 ports, users can enjoy ultra-fast external storage experience. ASUS M5A99FX Pro R2.0 motherboards also feature an onboard UASP USB3 controller to boost performance further when a UASP device is plugged in. The driver automatically boosts the performance of any device plugged in whether it detects a UASP compatible device or even any regular USB 3.0 or USB 2.0 device. USB devices plugged into ASUS motherboards also can be charged 3X faster than in other mainboards, saving users hours of wait time, and provides fast charging solution to a wide range of products that is not only limited to Apple iProducts but other smartphones and portable devices, as well.

USB 3.0

 

 

ASUS DirectKey

There is now a better way to access the BIOS other than rapidly tapping the DEL key on boot up. The M5A99FX Pro R2.0 comes with an on-board BIOS direct access button that can be pressed during standby mode to automatically enter the BIOS setup screen when the power is turned on the next time.

TPM Support

Despite being a mainstream motherboard, the M5A99FX Pro R2.0 motherboard has a Trusted Platform Module (TPM) header, providing extra security and another level of authentication compared to a software-based only solution.

USB BIOS Flashback

BIOS Flashback

To further simplify BIOS updates, ASUS implemented the new BIOS Flashback functionality in the M5A99FX Pro R2.0 motherboard which allows for a quick and single button BIOS update. The BIOS flashback utility does not even require any processor or memory module to be installed. All that is needed is for the 24-pin and 8-pin CPU power to be plugged in from the power supply (standby power). Users can just place a FAT16 or FAT32 formatted USB thumb drive with a UEFI BIOS file into the USB slot then simply hold the rear BIOS Flashback button for 3 seconds to initiate.
