It shows accepted #rate. I've got 2.4 too in theory 780/810/790 on my 3x280 rig, but #rate on stat page shows usually 2.1-2.5
If u got below 2.0 i bet it's ur settings.
You need to compare it to your WU not KH/s...
I am

My WU from 3 cards is usually 2.3-2.2 with those 3 cards. I was explaining that theoretical KH/s doesnt count so much.
my settings for 280x are standard so -w 256 gpu threads 2, I 13 etc.
Just using high settings for cards, got 3x Asus DirectCU 2,
first is 1130/1500 with 1.44 V and 2&3rd have 1170/1800 with default voltage. Whole rig takes 959W.
Temps ~70 degrees with 60% fan settings on all 3 cards.
I think i will change my settings to 1130/1500 for all 3 cards, with lowered voltage, because in longer run it will be more profitable i guess. I can get 770KH/s with 1 card with 1130 engine clock.
