I made this test, the scene is around 300x300 mt.
As youy can see noise bump map works, but height doesn't encrease, rightly I think, using a bump map.
Using noise bump map in displacement you can edit height.
Said that I will ask to developers what they think about.

Here's another test to illustrate the point. I baked out the procedural map--that's the front row. The procedural map is the back row. You can see they match perfectly in the diffuse slot. You can see that the baked out image works as expected in the bump slot. The procedural map doesn't work as it should.

Hi senorpablo,
The noise works in the bump slot, but is barely visible in your scene.
It seems that with the scale 100 on the UVW transform, the output of the Noise texture need to be amplified. Here we inserted a Color correction that allows to have the bump effect visible:

I hope that this will work for you.
Thanks for your reply. We can disagree that it "works." I found a work-around and shipped that scene some time ago, that's not really the point.
In my opinion, it doesn't work "correctly," or as people would expect it to work. There is no obvious or intuitive reason, from a users perspective, why a procedural map wouldn't behave consistent with it's diffuse output, or a similar bitmap image. I could spend some time trying to replicate the test in various other render plugins to see and demonstrate if my expectations and experience are incorrect or unrealistic. But, I've already spent considerably more time on this than I should have, in finding a work-around for my scene, and then subsequently making test cases for you guys.
I can't image that I'm the only person who has had, or will have this problem in the future. I believe addressing this issue would make Octane a better and more polished product.
