I don’t think ReClock has any control over the refresh rate, only the video and audio. The underlying problem is that video card refresh rates tend to fluctuate a bit, and are rarely at exactly
the rate you set them to (seems to be more of an issue with 24/1.001 than 24.000) and the video and audio rates are not synchronised. In my case, my display only accepts CEA timings, so I cannot use a custom refresh rate to tweak things. (though 24Hz is very close to 24.00000)
What ReClock does, is measure the current refresh rate, and adjust the video speed so that it matches it. So rather than outputting video at 23.976, it would send the frames at 23.97542fps in your case, and resample the audio so that it stays in sync with the new framerate.
Where ReClock gets interesting, is that it does not require the input to be a close match to the refresh rate. (you can adjust the tolerances) So even if Nvidia/AMD decided they wanted to one-up the other by outputting exact
video clocks (to be honest I wonder how good stand-alone devices actually are) ReClock would still have a purpose.
What this means, is that you can use ReClock to sync a 25fps (PAL) film to a 24Hz refresh rate to play back a sped-up European release, at the original 24fps speed. Similarly, you can speed up a 24/1.001fps film (US Blu-ray/telecined DVD) to the original 24fps—or whatever your display is actually running at when you select "24Hz". When playing back films on my HTPC, it gets output at the original 24Hz of the film, whether it’s a PAL 25fps release, an NTSC 23.976fps release, or a Europan 24fps Blu-ray.

Glad you got this sorted, and can see how good it is when ReClock + madVR are working together.
