I consider 80PLUS Platinum rated power supplies ideal for workstations, and 80 PLUS Gold the minimum standard. Rule of thumb for rock-solid systems, based on my considerable experience in overloading and destroying power supplies: The total sum of nominal wattage of all system components should not exceed 60% of the nominal wattage of the power supply. I wouldn’t call it “more than enough”, I would call that “cutting it uncomfortably close”.
I’ve been told that 1500W should be more than enough to power 4x GPUs The recent upgrade from 3->4 GPUs suggests to me a reasonable possibility that your power supply is overtaxed. You probably want to make sure your system is delivering adequate power to your GPUs, and you want to make sure the GPUs are not overheating. Apart from modifying your WDDM TDR timeout, there wouldn’t be anything you could do to try to address this, and as already stated, a timeout, by itself, does not represent a hardware or driver problem. However, even in that case, it represents a software development issue (defect in redshift) that would have to be addressed by the software developer. Note that the “win10 freeze” may indicated a more serious software problem (hung kernel, never-ending kernel) than just a kernel that ran slightly longer than ~2s.
A launch timeout is not a fundamental defect or misconfiguration of your setup, nor does it represent any sort of hardware or driver problem. If you just google “WDDM TDR timeout” you’ll find many writeups of how to do it.įinally, this issue should probably be addressed with the software developer. If you have a GPU that can be used in TCC mode, that would probably help, but I don’t know if redshift can recognize and know how to use such a GPU, and your 1080Ti GPUs don’t support TCC mode anyway.Īlternatively, you could try increasing your WDDM TDR timeout.
A launch timeout usually means that a kernel ran for longer than the ~2 seconds or so that is normally allowed by the WDDM subsystem.
