I have tried on 3 motherboard the Intel Rapid Storage Technology Smart Responce Acceralation wihout success. Once I accerale it, the performance of the system degrades instead of improving. Checking on IRST status I find every thing is normal, but the performance does not improve as the IRST promises. I don't know anybody else had the same experience.

List your system specs.
Also note that technology is meant to accelerate mechanical HDD's. If you have SSD's or a really fast raid setup then you dont need this.
