You cannot stress test via the BIOS.
An improper setup may lead to an over-heating condition as other have stated, but more important an unstable OC can lead to a corrupted OS and data.
The amount of time required to validate a 'stable' OC varies from one oc'er to another; I personally stress test using Linx (5 passes, max. mem), then use the Folding @ Home SMP client to confirm on 24 hours.
Using this method I never had a failed OC.
