when rendering lots of phoenix particles I get this error in RC7. The new build 4.0 crashes even after 1 frame. You cannot even cancel and see the error message. It renders but has an error at the same time.

here is the error. Not sure how it is out of memory when I use CPU ram

CUDA error 2 on device 2: out of memory
-> failed to allocate device memory
device 2: failed to allocate space for geometry (1)

also this happens while octane viewport is open due to denoising

Hi coilbook,
what about your TDR delay?

Thanks I'll change it. Could you please test the scene I sent to you as PM and add phoenix liquid grid that I attached in the post viewtopic.php?f=80&t=69843&start=20. Thank you

Hi coilbook,
yes we'll do it.
