This is not a flame just a friendly piece of advice/information. (all said in a calm soothing voice like a parent reading a fairy tale to a child)
The tachometer indicates engine revolutions per minute. At around 7000 RPMs you will see these red markings on the tachometer. Red means stop. If you do not stop accelerating the "rev limiter" will stop the acceleration for you by reducing power. It is best for the car for you to not use the rev limiter, instead use the "common sense limiter" and shift before the red.
The BMW M3 is a high performance automobile. It is meant to go fast and hold the road. To go fast depress the accelerator. The higher you let the rpms (see revolutions-per-minute above) get, the more torque and horsepower the engine will produce. For maximum acceleration shift at 6900rpms or just before red line. The engine will sound loud and scary but if the tachometer is not in the red, then you are simply using the car as it was intended. Shift at lower rpms for less agressive driving and fuel economy. Shifting under 3000 rpms is...well....just...wrong (IMHO) for this type of automobile (sniff).
So don't worry about 5,000rpms, if anything your engine was dissapointed that you did it by mistake.
