My first attempts were made with a too hard pencil and basically had almost no effect.
Then I overdid it using a classic soft HB grade pencil and my BlueFuries went to well beyond 3GHs which caused me to carefully undo and re-apply the pencil mod.
For now I'm running two at about 2.45Ghs and one at 2.8GHs with no unusual HW error rates or other malfunctions (have a big USB fan keeping them very cool).
I used a I think a HB pencil first, then re-did it using a 4B with a little bit of 6B on top of it. They seem to like the 4B pencil better. That's why I was asking if my USB hub could be the cause of not hitting numbers past 2.4 GHS.
Before I used the 4B I was getting about 2.3 and 2.2 GHS. With the 4B last night the most I got out of it is 2.46 and 2.33 GHS. That's with me watching and refreshing minepeon as I'm doing it. Could it be that minepeon doesn't have that most updated version of BFGMiner??? At this point I'm just happy that I was one of the few who just plugged in my Furies and they were up and running out of the box. I had to fiddle around a little bit to get the Antminer running right. It doesn't like going past x0981. I tired x0A81 but it wasn't going past 2.1 GHS and it had like 20% errors.
This is the hub I got.

Like I said, could that be the issue???
Thanks to everyone on here for the help!
