need some help again.

4 gigs probably isn't enough for 2 cards since some people have reported 2 gigs being an issue for one.

I could finally start gpu mining after putting a 4 gb memory.
But still have couple of problems.

1. I have 2 gpus but only one of them is working. Both of them work well when i mine ltc but  Gpu 0 doesnt work for mmc mining.

2. I know 1 280x gpu can mine about 20 coins but when i checked my wallet i could see only 0.5 coins were mined for the last 6 hours. Hpm is about 19 and i can see result is accepted.
