For an excellent explanation of the problem of intersample overs, I recommend John Siau's article:
John is the VP and Director of Engineering at Benchmark. He explains how this problem occurs in the reconstruction filters in over-sampling D/A converters, and notes that the maximum peak above 0 is 3.01 dB. Benchmark is one of the few companies that has addressed this issue in their D/A converters.

I use an oversampling peak meter that gives the exact true peak level.
Using a limiter that is NOT oversampling = cannot detect interstitial clips I see regularly peaks going 2-3 dB above the 0 dB F/S max level.
While the nonoversampling meter only shows -0.1 dB F/S that the nonoversampling limiter was set too.
If you can live with that fine but I prefer to use a true oversampling peak limiter to get the levels accurate.
