ASUS ROG Crosshair IV Formula motherboard ASUS Unveils 890FX Boards; Crosshair IV Formula & M4A89TD PRO
ASUS today has unveiled two AMD 890FX based motherboards that supports and pushes the limits of the new Phenom II X6 CPUs with 2 new exclusive features; Core Unlocker and Turbo Unlocker. The Core Unlocker turns a budget quad-core version of a CPU into a full six-cores while Turbo Unlocker overclocks the CPU.
Speaking on the inclusion of these two unique tools, Joe Hsieh, General Manager of Motherboard Business with ASUS, said: “ASUS will never stop developing the friendliest and most performance-boosting features available to consumers, whether enthusiasts, beginners or anyone else. Both Core Unlocker and Turbo Unlocker realize CPU potential, making them ideal for users looking for the best value on the best performance motherboards around.”

Press Release :

Unrivalled CPU Unlocking Leadership
ASUS shows the way in extreme PC performance with the inclusion of Core Unlocker on new 890FX boards. This technology has garnered much acclaim from international media since its inception, and remains the most reliable and successful way to unlock additional cores for performance improvements on motherboards using the AMD 800-series chipset. Core Unlocker makes it possible to turn a budget quad-core version of a CPU into a full six-cores for significant computing gains*. 
It is accompanied by Turbo Unlocker, an intelligent overclocking engine that opens up CPU performance instantly by CPU core ratio when engaged in heavy computing or intensive tasks, including gaming.

Both Core Unlocker and Turbo Unlocker realize CPU potential, making them ideal for users looking for the best value on the best performance motherboards around.” 
Real Time Boost on All Phenom II Black Edition CPUs (2/3/4/6 Cores)
Turbo Unlocker represents the next evolution of performance tuning from ASUS. Designed for AMD Black Edition and 6-core processors equipped with an unlockable multiplier, it intelligently adjusts CPU clock speeds with one-click input from users to attain even more computing power. When running single-core optimized applications, Turbo Unlocker dynamically adjusts resources and ensures maximum performance on dedicated cores. For multi-threaded applications, all cores supercharge to the highest performance available. Performance gains occur dynamically and instantly based on actual system conditions, so overclocking is always safe and stable. 
Turning Four Cores into Six
Using a switch on both new motherboards, award-winning Core Unlocker is an ASUS exclusive that leads to fast and easy performance gains through the activation of latent CPU cores. One press sets Core Unlocker going as it scans the CPU for additional cores and puts them to work for major computational gains. Heavy multitasking, rendering and gaming go faster and better with additional cores available, as Core Unlocker can turn a dual-core CPU into a tri or quad, or turn quad-core versions into a full six-cores for significant computing gains*. In many cases Core Unlocker has demonstrated up to 103% in added performance?it is a supremely capable technology that injects great value into these motherboards. 
Faster than Ever Connectivity
Both ROG Crosshair IV Formula and the M4A89TD PRO boast native next-generation data USB 3.0 and SATA 6Gb/s. These super-fast connections bring users into the HD era with the speed and reliability needed to handle large files quickly. The motherboards feature two USB 3.0 ports each, transferring data at up to ten times the speed of USB 2.0, so moving an entire Blu-ray disc (25GB) takes just 70 seconds. SATA 6Gb/s offers twice the throughput of its predecessor, making hard drives noticeably more expedient. 
With the performance and speed demanded by users constantly rising, these technologies could not have come at a better time.
