Gpu identification

I have a rig of 6 gpus. My question is how can I tell which gpu is 0, 1, 2, 3, 4 or 5 on gpuz or watttool? Thanks.

run -g 0 for the the first GPu and see in GPU-z, the one that have 100% load is g0.
Do the same for g1 to g5

do you mean type run -g 0 in dos prompt?

in your bat file -g to specify which graphic card to use.

Oh it already has the -g in the bat file. What I wanted to know was what card is in slot 0, 2, 4, 5? If I have different gpu mfg, I want to know which cards belongs to which slot. GPUz only gives you a drop down list of all the cards but it doesn't say which card slot it belongs to. Hope I'm making sense.

Because you run 6 card at the same time -g 0 1 2 3 4 5, I said that run only one card by using -g 0 to see the gpu load in GPU-Z and in gpuz you can know the slot that have 100% gpu load is g0 in bat file.

ok i think got it. I was hoping there would be a tool out there that would tell you which card belongs to which slot with all cards plugged in. I can try this route. thanks!
