OC 2020.1 How to engage NVLink memory pooling?
Posted: Thu Jun 25, 2020 6:59 pm
I have 2x RTX 2080ti connected via NVLink, but Octane doesn't seem to use the second GPU's memory. I set the "Peers" in device preferences but it doesn't seem to change anything.
I know Octane is NOT supposed to show a larger memory pool in the System panel. Instead, once the main GPU's memory limit in exceeded it should overflow into secondary GPU's memory. Thing is, once the single GPU memory limit is exceeded, Octane starts using Out-of-Core memory instead of VRAM on the second GPU, as it would without NVLink. I'm using 451.48 Nvidia drivers and 2020.1.0.55 version of Octane.
Am I missing something?
