We should start a new Fury/Blizzard thread for those of us with those devices. I thought about doing it, but haven't had the chance to really sit down and compile the information and stuff.
These things do run hot, and if you look at the circuit board, there are some test points with voltage markings next to them. I have a good idea that the points are labeled for core voltage, bus voltage, etc. If you check some of the pics on this link you can see in the upper left there is a point labeled 1.2vc...I would assume that stands for 1.2v core. There are some other points on the other side of the board labeled 3.3vb and two labeled 1.2vb. I haven't measured them yet though.
So far I've been trying to reduce the number of errors with settings and cooling. I found some discussion on litecointalk where they mentioned that the speed 336 combined with higher difficulty reduces the number of errors. I set the speed to 336, and at least on Manicminer pool the diff is set to 256 (or close to it) and so far out of 650 accepted shares, I have 29 hardware errors and 0 rejects (4.4%?! if my math is right...I'm tired as hell)
I also added some extra cooling. The back of the board is smeared with a VERY thin layer of thermal paste...and it actually was making hardly any contact with the heatsink. They should have used more paste or a thermal pad. So I put dabs of paste on the backside of the board where the chips are, and added some heatsinks to the tops of the chips as well as the mosfets. After the added thermal paste on the backside of the board the heatsink is noticeably warmer indicating more heat is being transferred to it from the board....so that's good. The heatsinks on the top of the chips don't do a lot of good by themselves unless there's a fan pushing air through the case over them but that's for another time. I have a second Fury coming so I could slap them together and make sort of a blade configuration with a fan on one end blowing over all of it.
Anyway...here's a pic where you can see the voltage test points and added heatsinks.
