Two GPU's but only one working

Hello
Recently I have upgraded my machine and now I have two GPUs. In Render Settings > Advanced tab, I have selected both GPUs, but when I look in Task Manager at performance I see that one GPU is used 100% while the other is at 0%. Not sure what I'm doing wrong.
Comments
A) Which two GPUs? If one has substantially more VRAM than the other, that might explain it, because a render will only use GPUs that can fit the scene into their VRAM
B) Task Manager doesn't give a particularly accurate view of GPU usage. Try GPU-Z.
Thank you. I have tried the GPU-Z thing and there it showed that both GPUs where working. It seems that the problem was with the Task Manager
What GPU's are you using for this? I'm assuming they're Nvidia GPU's so that you can GPU render, as AMD GPU's aren't supported for GPU rendering in DAZ at present [unless something changed since I last checked]. I'm looking to do another dual GPU build with Nvidia GPU's this time, but it's a bit difficult to find updated information about which cards still have mGPU support. I believe Nvidia once had it on the 3060, then removed it after the 40 Series was released. I've been asking around but no one would respond. When I look up the specs, there's no mention of it aside from the standard mGPU is dead schtick that isn't actually true outside of gaming.
