m8 dont get me wrong, but, buying 6 750ti to mine scrypt is like buying a mini cooper and going off road. Let the pool take its due, 5,5MH for 6 750ti seems low, my 660ti gets up to 2MHZ on latest CC miner alone, and I know for a fact that one 750ti can get better than that, while running cooler and not needing so much watt.
Were I you, I would definitely hit the cudaminer thread, you totally need to finetune your cards if u dont get more than 10MH.
TL:DR 750ti has the best MH/watt/investment ratio for x11, you need better settings
No offense taken, but I think your analogy is all off: It's like buying a monster truck and never taking it off road... or buying a race car and only driving it to starbucks.
Getting 10.5 Mhs now on the x11. If I'm using ccminer, would I still hit up the cudaminer thread to do some tuning?
And yeah, you do need to visit the cudaminer topic or google for ur cards settings, you can certainly do better than that
