Do you have sometimes tips, how do I get this pixel cleanly? Like one sees the Render time plays no more big role probably there.: (
Once 1600 ca 3,5h passageways and the other time 6000 ca 8h.

First of all You need to identify what is causing that noise:
* Try to give more samples to smaller lights or those who have difficulty to reach certain areas..
* Use some octane features (like hot pixel removal, etc) to get rid of noise.
* In the end simply render bigger image & rescale afterwards..
Some of those methods I've tried to put in a free scene
(look at my signature for a link =)
if You'll not be able to find a solution, post full image (or even scene) & I'm pretty sure some users will help You to figure out what's causing the noise =)

First: Thank you. 
Nevertheless, I will raise the lights where it goes the samples. Default stand this on 100. What would be a good value? 500? 1000?
Which Features you still mean. This would be really important.
It is a big scene, At night. artificial lighting. My titan is covered with 5,600 mb Ram.
Excuse if I do not understand so properly.
However, I present myself strives itself.
But I understand badly in English. Rather in German.
It is thereby extremely difficult for me.
I have many selfluminous surfaces. No Octane area Lights. And a fat lighting HDRI in the background.glimpse wrote:First of all You need to identify what is causing that noise:

I have none specially camera in use. Hotpixel stands on 1.* Use some octane features (like hot pixel removal, etc) to get rid of noise.

The noise is in the dark areas (under furniture). Or where light intersects. This free button (as shown in the picture).Some of those methods I've tried to put in a free scene

The value for the lights (samples) is relative. Try to raise small lights to 100, 1000, etc. Look to result as You go, how Your tweaks effect it, is there any noticable difference?..
Lower hotpixel removal, to 0.5, make a test run then adjust to .2, & even 0 - no need to rerender (as I remember), simply save out - & compare in photoshop 100% crops. Sometimes if You leave it too low, it might blur some details, so You better be sure You have enough resolution.
Play with Filter size, caustic blur parameter (in certain situations it might help to remove some noise that)..
It's very hard to recomend something for sure as we don't see the scene. There different things that could cause noise..
hope it helps at least a bit.
Post some progress as You go =)
