LOL, so you took all the online advice and your buddy's and just dumped it all in the trash?? why would you do that? I have to sadly inform you that you are likely going to regret doing that, heck, I feel bad for getting those gears LONG before the reviews started coming out, I sure as hell would feel worse if I knew in advance that I was getting some shit-gear.

Don't even think about overclocking them, your experience with computers will not serve you once those gears go bad, it isn't a matter of gluing a heatsink, the chips themselves will go bad or become loose, identifying the chip/chips that need fixing require some special tools, acquiring the replacement chip from China is some serious pain on its own, fixing these mining gears isn't something the average joe with some computer background can fix, so chances are you will have to send them for repair, which is costly and takes forever to be done, assuming the will be in a fixable state anyways.

Keep these gears as cool as possible, forget the overclocking thing all together, that's my advice.
