OK - not keeping up with all of this. I see there are h-boards available on the website. If I order one, when is the "expected" delivery?
In stock H boards ship immediately but they only work with the older M board. I bought 4 of them and they are nice hashers right out of the box with no OC mods. Averaging about 33GH/s per board.

What is that monstrosity you have on the inductor? Good gravy man, looks like a rhino ran it over.

Tired of substandard power distribution in your ASIC setup??? Chris' Custom Cablez will get you sorted out right! No job too hard so PM me for a quote Check my products or ask a question here: https://bitcointalk.org/index.php?topic=74397.0

Nice results, goxed. What voltage are your boards at (once they're heated)?

These are good overclockers as well, but the price needs to be slashed for it to make business sense. You need to understand that MGP would never reduce the price while there are still October orders to deliver. Also, these H boards are "in stock" and offer about the same value as other in stock ASICs like Avalon and ASICMiner. ROI is really beside the point in the current ASIC market and has been ever since Avalon batch 1 & 2. But if you want to mine, you have to pay the price. Otherwise, just go buy BTC, lol. Telling ASIC manufacturers that their products are overpriced is an absolute waste of time as long as there is a demand for them.

The boards with good chips are at 0.9V, the ones with >=2 bad chips are at 0.95V

The boards with good chips are at 0.9V, the ones with >=2 bad chips are at 0.95V OC to .95V overkilled and must have heatsink + fan.

The boards with good chips are at 0.9V, the ones with >=2 bad chips are at 0.95V impressive. I cant get past 0.88v (39-41GH per board) without having chips or boards drop to 0 hashrate or produce massive3 error rates time to time

I have put up a reference picture in this thread. if you copy that you should get the board up to 0.9v provided there's good airflow.

I have put up a reference picture in this thread. if you copy that you should get the board up to 0.9v provided there's good airflow. I have good heatsinks but perhaps could use slightly larger ones on the regulator/inductor. 0.865-0.87 is good for 40GH on my boards, but the pencil mod ramps up to maximum (or minimum?) resistance over a few days and its difficult to get the exact balance. once it climbs to >0.88v the boards become unstable and i see high error rates followed by entire boards or just some of the chips dropping to 0 every few hours and upkeep is a PITA. i'm sure if i had cold air moving through the heatsinks (rather then the 21 C room temperature) I could reach 0.9V though, or at least achieve a stable 0.88v

Kudos!

Kudos! thats what i figured. Right now its running around 0.86-0.65v and producing 76-79GH fairly stable

You are aware that ghash.io has nothing whatsoever to do with Dave's operation, right? That is not the 100 TH mine. I don't know where people get that idea from, but it's untrue.
