How to speed up the render time?

With the help of a reliable and trustworthy source, you can achieve a fixed match. First, let me say that a fixed match is real, and many know this. However, these people were deceived in their search to find a genuine one. Like yourself, myself, and many others. Nevertheless, the chance of finding a real fixed match source is 1 in 50, and this is within a certain period.

By lots of detail, I am assuming that you have several maps of each object and likely at least a few lights in your scene. Even with a good graphics card, high resolution animations can take a very long time to render if the vertex count is high, and the number of light passes is set high as well. Try reducing your light passes to speed up your rendering. If you must maintain very high levels of detail and high light pass/render pass, consider a plan at a render farm. You simply upload your blend file and then they render for you and its done before you know it!
