Hardware / Threadripper 2990 Performance Issues
« on: 2020-01-13, 18:34:38 »
Hello Coronists
It is all about render-speed on our Threadripper-node: We use a TR 2990/Cinema4D Setup as a render node since a year. At the beginning (I think, it was when we used Corona V3), all felt very fast – and renderings where calculated in no time. This changed, when we compared the results of the Threadripper and one of our iMacPro Workstations that has an 8-Core Xeon last fall (in Corona 4 hot fix 2&3). The results where +/- at the same level.
Then I built an additional render node, based on the new Ryzen 3950. Now we are rendering a movie clip – and while the results of the Ryzen 3950 (with a Cinebench of around 9000) are pleasing (14 minutes per frame), the Threadripper 2990 node (with a cinebench of around 11000) takes more than double the time for each frame (32 mins per frame).
For making sure, that there is no «cinebench-error», we rendered an image with good old physical rendering. The result was as we expected: Threadripper goes around 20% faster than Ryzen.
While researching, I now found several entries in this forum, that are about RAM and correct setup. We use 2 x 16GB Corsair LPX at 3200MHz (our MoBo is a Gigabyte Designare x399). Can it be, that we need to add some more RAM-Modules to get better results (at least two channels instead of only one? Or are other clockings of the RAM better than 3200 MHz? What RAM-Setup would you recommend?
Thanks for your help - any advice is highly appreciated!
