1. You should follow this hardware and setting guide located here: https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison , give that a shot with some predefined settings and see how that goes - a lot of people have luck using that.
2. You do not need to install the SDK, all the recent drivers have it included. If you install both, they could be overwriting eachother which is something you don't want.
3. With 12 in mind, the most common issue with this card (I have a bunch of) is the thread concurrency, and correct clocks. It is totally necessary to play with the clocks for this to get the speed that will help you out, because they can be finicky. Every system is different. Make sure when you finally find a good clock that you have 0 HW errors, as it can damage the card if you start to get any.
4. Consider flashing the bios, it will reduce the power consumption and save you 50watts on each card, you are looking for the newest F43 bios.
Good luck

The README file in cgminer (I think that's where I read it), says that SDK 2.8 is bad for mining. Get rid of it and try 2.7 and see if it helps.
That's the same GPU I use and set thread concurrency at 22400 for optimal hashing.

Do you still need to install the SDK?
I thought the new drivers come with the SDK already?

Drivers? APP SDK? Correct threads and shaders? Intensity =19 or 20?
Hey all,
A friend of mine recently purchased a few GIGABYTE GV-R795WF3-3GD 7950s for a litecoin rig. Cant seem to get these bastads to do anything over like 300khash ish.
PC has 8gb of memory.
OS is Ubuntu with AMD 13.1 drivers and SDK 2.8
Using CGMiner
Have tried all kinds of things but cannot set the thread concurancy over 8192 for whatever reason.
Link to card on the egg.
