Just a preliminary post, "BUT" I may know why these things aren't hashing correctly and I don't think it has anything to do with the chips or power.
Can you give us more information?
Here is a copy of my cgminer screen.

It has been a very long long night. I have seen spikes of near 65GH/s with the following start command and replacing of the Power with a bigger brick. That was a snap shot of about 10 minutes running.
Command Line Args:
--bmsc-options 115200:0.65 --bmsc-freq 0D82 --bmsc-voltage 0850
I wouldn't recommend this for others just yet. Also if anyone knows a better one to reach what was promised please let me know but for now this is stable. I will attempt to post video's and Picture's tomorrow to show what lengths I had to go through to get this to work. Granted the base components are 1x120mm Fan, 1 Gridseed Power Connector, 1 "Cincinnati Tool CO." C-Clamp, and the corner of my table for now. I am hoping to find some components tomorrow to redesign the bottom half of the case tomorrow. Yes this is where I believe the entire problem is. But like I said I will dig a bit more tomorrow.
Also if Bitmain has anymore
then just coupon's that I can't use to give me, please let me know. (I don't spend BTC for mining equipment... USD ONLY....) to add please do? Also added name here to name there. I got 1 from minersource.net. You will see what I want to order in my cart.
