In the long run the GTS 450 is going t be unsupported at all. The Fermi chips used ti make them do not support OpenCL 1.2. If you have the variant made with a GF116 chip instead of a GF106 it supports a bit more of the OpenCL commands introduced between 1.1 and 1.2 and will fail on projects less often.

But the current requirements are support for both OpenCL 1.2 and double precision (FP64).

In early 2020 there were still some Core_21 Work Units, Which were lax about needing OpenCL 1.2, but with the new COVID work, they were all Core_22, which needs OpenCL 1.2. While I have seen no official announcement that Core_21 is retired, it has been almost 2 years since I saw one.

Early versions of Core_22 would sometimes process on Fermi based GPUs as well. But WUs from some projects that created calls to missing OpenCL functions would fail, not always predictably. WUs might work on one model GPU using one type of Fermi chip and fail on a different one. There are also two generations of Fermi chips, the GF11n chips worked a bit better than the first GF10n.

It's a Fermi GPU that has been unsupported by nVidia for a long time now ... Kepler GPU support has also been dropped recently but the drivers are still new enough to use them.

I guess the time has come to completely turn off Fermi support on FAH with the latest version of FAHCore 22 ... :(
