I have an Nvidia Quadro P4000 GPU which has been running perfectly satisfactorily and without any apparent issues since it was installed in my previous Windows 10 system in 2017.
I recently built a new Windows 11 PC with an i9-13900K CPU and 64GB RAM on an Asus Z790 Proart Creator board and transferred the P4000 to that machine. Everything else runs perfectly on the new machine, but since then I have been plagued with random GPU crashes on file export in both C1 and PTGui, although no other software appears to be affected. Both applications may run without issue for several days, or may crash either immediately or part way through a batch export (C1) with various OpenCL and nvlddmkm errors. Following the initial crash, and even if one application or the other was previously running without any problems, both then continue to crash every time until the system is restarted, which appears temporarily to reset the card, driver or whatever is causing the crash. Both C1 and PTGui also run perfectly when exporting via either the CPU or the iGPU. As far as I can tell, the Topaz AI applications, which use the GPU heavily but run under OpenGL, not OpenCL, also all run without any problems under the P4000.
Neither C1 support nor PTGui have been able to reproduce the issue or to offer any further suggestions, and I have so far tried just about everything obvious apart from the more intrusive measures such as a complete teardown and rebuild of the machine to check for physical damage (bent LGA socket pins etc) or a full reinstall of Windows 11 from scratch.
The crashes appear to be directly connected with the GPU and/or the Nvidia driver, but it is not at all clear whether that might be due to a faulty GPU or motherboard, the driver, a GPU/motherboard/Windows 11/bios incompatibility, or anything else. I have already tried a full driver uninstall using DDU and a clean installation of various drivers going back several major versions, with no improvement.
In the event that no contributory factors can be located in the main system and I am forced as a last resort to replace the P4000, can anyone offer any suggestions for a suitable alternative? Use would be mainly C1, PTGui, Photoshop and the Topaz AI suite. I'm rather out of the loop with recent GPUs, and everything seems to be primarily gaming-oriented (and overpriced) these days. The simple answer would be another Quadro, but the nearest direct equivalent is some £980 and I don't want to go there. I'm also not confident that another Nvidia card might not have similar issues, and I know nothing about AMD.
Has anyone tried Intel Arc A750/770? It looks very interesting on paper as well as reasonably priced in comparison to Nvidia and AMD, and there have been some positive reviews about its performance with Photoshop and other creative apps, but I can find nothing about C1. There is also the question of it being a first generation product as well as the drivers very much still under development, and it is also unclear as to whether it supports 10-bit output. The latter is perhaps not an absolute deal-killer, but I do highly-accurate art repro professionally and it would be nice to have (and the original reason for the Quadro).
Any comments or suggestions for suitable GPUs would be gratefully received; and, if anyone has any ideas as to what might be causing the crashes in the first place, that would be a very welcome bonus!
Many thanks.
