A few questions

[Burt]

Im using a GTX 570 to mine on the btcguild pool but I also have a 9400gt that I am not using and I want to use it to mine even though it wont help that much. I put it back into my computer but its not showing up in GUI miner. Any ideas why its not showing? and how would I get it to show?

Also if i get it working should I have it use the same worker in my btcguild pool or should I make a new worker?

Thanks

At current difficulty, a GTX 570 at full power 24/7 would end up wasting more electricity and cannot be offset by bitcoins earned.

Not sure why it's not showing though, what OS is it and PSU?

According to https://en.bitcoin.it/wiki/Mining_hardware_comparison 9400GT does    3.37 MHash/s.

Does it show up in Device Manager under Display adapters.

[Burt]

No it does not and im not sure why.

[doomy]

Yeah that's the root cause of the issue, try moving to another slot (if available), check on another box etc.

The slot is working though the fan is spinning
