OK ,your miner are working.

Your card listed?.. https://litecoin.info/Mining_hardware_comparison
I have to play a lot of trial and error with my cards, the 4 gig 270X’s (they outperform some 280’s with less power, why I went for the 4gigs, algo dependant) aint listed there and tbh, I really cba compiling for the linux box, I’m being lazy, letting the coders code before I poke at the new toys.
Just throwing this site out there, cause no way a 280 should be running at only 1k 1050 minimum, sure, ramp it up in 5’s from there, till the drivers crash, roll it back 5, start with a standard 1500 memclock

No errors. This was running overnight. nVidia GeForce GT 630M

What does WU:x mean?

What does WU:x mean?
WU: The Work Utility defined as the number of diff1 equivalent shares / minutehttp://bitcoin.stackexchange.com/questions/19260/deciphering-cgminer-interface-in-terminal
So I’m guessing the higher the number the more efficient your miner is
-
Ah nice. Cheers.

Which version Catalyst is best ?
my 7850 ,7970 are HW ,not work.
-
I think 13.4 is the best, but 14.4 for me was only 1% or 2% slower so not a huge difference.
I was running 8.something and that would crash cgminer.
What version are you currently using?
-
I use AMD 14.4 Catalyst + SDK 2.9 .
Can you mine with AMD 13.4 Catalyst + SDK 2.8 ?
-
I could mine with just AMD 13.4, I didn’t have SDK installed at all, although I now have installed SDK 2.9.
I have a Gigagbyte HD7870 GPU, running Windows 7 64 bit
-
There have been known mining issues with 14.4 since release, 13.12 max on windows.
-
The best choice:
AMD 13.12 Catalyst + SDK 2.9
AMD 7850 CARD =48Khash/s ;
AMD 7970 CARD =16Khash/s ;

I gave it a try last night on my nVidia 550M, Win7 and I got max 8 khs. Mostly default settings, --worksize 256 -I 13, no overclock. Driver version 294.10 - a bit old
76C gpu temp -> not bad
I think it can reach up to 10 khs with some tweakin
This is what i get with -I 14
Limitation of the gpu?
And whats the logic 7850 to perform 3 times faster than 7970?
Do you guys expect the stratum implementation to raise the productivity significantly?
-
Try dropping the intensity I am using 11 on my 7870, on I 12 it drops performance by half, and on 14 I would probably only get around 8 too.
For normal Scrypt I 12 is the sweet spot for me but 11 is required for Neoscrypt

Is there anything special you needed to do to get cgminer working with nvidia?

absolutely nothing… works right outta the box. I am curious to see what a decent desktop nvidia could do
