I remeber something like "...it can go up to 6 mhs if u can cool it....".
I don't see that much. With external cooling and running at the max frequency of 954mhz, both of mine are doing ~5.45Mh/s.

Pushing it that hard, with all your equipment (hub, ext cooling), I'm sure u are equipped enough to measure somehow ur temps, because as I undestood it from last few posts, it matters alot. Maybe even with ext fan its too hot (or both of them). I am just guessing. But if you are complaining because you feel cheated somehow because you expected 5.8-5.9 I have no answer to that. Max I saw was about 5.80 on one post showing "simulation" or something like that. I am getting 4.40 @796, one piece, no hub, in 3.0 laptop port and I don't feel cheated btw., but respect everyones questions and feelings.
