Ok, so I've finally got all the correct pieces together, and I'm scratching my head a little bit. I've got the GekkoScience 7-port hub, the GekkoScience 12v 8a power supply, 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), 2x 2Pacs and an Arctic Breeze USB fan. There's a secondary Arctic Breeze fan being powered by the pc tower to keep temps down.
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?
I'm running the newest CGMiner version from the front page from Windows 10. I've seen one of the sticks hit 101GH at 450 but that's the best I've seen. Does this come down to operating system? I've also tested without the 2Pacs on the hub and I get similar results. Could it be that one stick is just inferior to the other two?
