Is anybody fighting to increase their hash rate ? I have set up my miner in a vastly superior manner the air flow is miles better the GPU's are a lot cooler, But I've seen a 420Kh/s drop in performance on the site and also locally, I am not going mad, The cards are hashing at 1780Kh/s normally, And now I've seen them go down to 1360Kh/s WTF ?

Whats going on ? Is somebody playing games with me or something ?

There's no way its a configoration issue as the cards are still set the same way they was since i got em, And its not blown VRM's as sombody pointed out before because they have been working fine for days at high rates, Since the last drop

Anyway I would love some feedback form you all cheers.
