3x NewPacs (one older generation, 2 newer generation - the older one has a sticker on it like the 2Pacs did with it's serial on it, the 2 newer ones don't and the chips are tan colored instead of black like my original NewPac)...

I would assume you are referring to our serial # tags we used to place on the units. A number of customers have asked that we no longer do that, hence, the newer units dont have product tags on the side of the heat sink.

From what I've read, the hub should be able to support like 6x NewPacs at 600MHz. I'm running my 2Pacs at 275, and the NewPacs at 450. None hit the hashrates they should; at 450, the NewPacs should be hitting 102.6, and the 2Pacs at 275 should be hitting ~30. Two of the NewPacs are close, they're at 98.23GH and 99.95GH, which is within 5% of where they should be, but the 3rd is sitting at 91.9GH and the 2Pacs are sitting at 24.71. They've been stable at least, and I'm pulling this data after about 24 hours of hashing. Is there something I'm missing?

Like sidehack did already answer, not all chips are going to hit the same speeds. have you seen any plateau's from cgminer and had it step down the frequency on the units? and Always remember, more power, more heat, so more cool means better hash rates.
