Well, so far the best I can get out of a set of 10 is about 3.5Mh/s (850MHz)...a far cry from the 5Mh/s or so in the "secret picture" Jack has in the original post. I hope this is going to be something we can expect with a future firmware update to the controller. I tried turning the little voltage dial up on the power supplies, but it didn't appear to have any noticeable effect.

Had to cut and strip the power cables for the PSUs but it was the green/ground white/neg black/pos wiring someone else posted here, so that was easy. All of my miner cables were correctly colored. Unfortunately, the power cable for one of the USB hubs was bad out of the box...but I had another cable in my giant box of spares that works.

Setting these up is a cable management nightmare, but I've got it to where I'm happy with it. Now I'm just going to leave them overnight to do their thing and see how it goes. I had one of the controllers reset randomly on its own once, that I noticed - hopefully that isn't a frequent occurrence.

So far, I like these little guys...they look unique and the gadget factor is there. I just wish I could get the 500Kh/s performance seen in that photo...I wish Jack would tell us what was done to achieve that!

Are you having problems with the controller? Every 12-14 hours my controller randomly craps out and randomly starts working again a few hours later after unplugging+ replugging it in over and over again.

Yes...it's really annoying. I have no idea what's causing it, other than it just being a piece of junk.

Also, fun with screen shots time...Jack's "secret photo" in the OP is what made me decide to buy these, figuring that if they each did 500Kh/s, that would make them worth the investment. Unfortunately, I've only managed to average around 350Kh/s each. However, at one point after switching from 800MHz to 850MHz I did see this reported by the dashboard (see screenshot). Proof positive that anyone can post a "Wow look at these high hashrates" screenshot as a form of semi-false advertising on the Gridseed performance. Unless something radically changes, you won't see this kind of performance.



How do you get your controllers up and working again?

They seem to randomly cycle themselves for unknown reasons but occasionally when they stop responding via the web interface it requires you to power cycle them. Really annoying, got to train my wife how to do it so we dont have downtime while I am at work.
