CUDA is for nVidia cards. Don't know why your messing with that on an ATI/AMD card?
Also the 3xxx series cards aren't supported by OpenCL which is which is required for mining. Get a cheap AMD card listed here that actually works. Of course I don't scrypt mine so I don't know which ones will actually work for that.

Topic: HD Radeon 3400 (Read 1107 times)
i have tried cuda, cgminer, reaper and gui and none of them can find my card. i realize this is a really low card but it doesn't matter. i simply must get it online for the release of my scrypt coin, so even a few khash will be ok. i humbly beg someone to point me to a mining software that will recognize the HD 3400. i got catalyst, vision engine, and the driver installed, as well as the APP SDK. what else do i require to mine with this card. and yes, i realize this card has no fan. to prevent it from overheating i've jerry rigged a fan to each side of the card, one blowing down through the blades and one blowing down onto the back of the card.
