Personally, I have found the 'Auto Detect' in the more recent NEDs to not even be close to accurate, so we explored the limits the old fashion (and very time consuming) way. Beginning with our 425MHz core and 650MHz memory speed we inched our way up to the wall of 477MHz on the GPU and 721MHz on the memory. This puts the Albatron 5700P Turbo at the same GPU speed as the Ultra model.
