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

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

are you using heatsinks? especially on the regulator and the lower half of the board? 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

OC to .95V overkilled and must have heatsink + fan.

Depends, I have atleast 2 chips that are dead at anything less. Infact they are happy at 1.0V as well, but the regulator approaches its limits.

in the case of bitfury it is unlikely they can make a board for any less than $200 (and continue to pay off nre costs) for some time.

That is BS. They can make it for less than $200, easily.
The board can be done for $50, chips $5/ea (using their own January pricing). The chips are probably less than $1 each.

Just watch, they will charge $400 or $350 for November deliveries. And slowly sell them to new people.

BTW, we are right on track to clock 40% increase in this step. We are ~500 blocks out of 2036 and difficulty is already projected at 10% more.

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

I tried to cut that heatsink to size with pliers. Guess I need a dremel Wink

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.

Thx. That's what I have. The old board.

Well, I cant say you are wrong mainly because I really have no idea, although it seems like a bit of a jump in hashing power to hit those numbers.

+30% jumps are conservative. BFL is still shipping, so is KNC; HF, Cointerra, BA are still unknowns. Then you have bitfuries. I suspect we'll see 30-50% jumps every 2 weeks at least until Feb/14 or Mar/14. Monarchs and BAs shipped in numbers will culminate this run up.

I think people who ordered Monarchs will be dumping their pre-orders sometime in December at 50% loss.

BTW, Bitfury kits for November better be in the KNC price range, i.e. $3-4K per full kit. It all can change very quickly if HF demos their chip.
Then $3K/full kit will become expensive overnight.

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. Wink

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.

This is insanely overpriced. $8000 = 40BTC.

400GH will get you only 27 BTC.

http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=390928787.63809&dcosts=8000&diff_mincrease=30&blpbtc=25&dhsmhs=400000&diff_mincreasedecrease=3&btcusd=190.75&dpowcon=30&btcusd_mincrease=1&pcost=0.25&calcweeks=32&dleadtime=0&action=calc

Why would someone spend $8000 to buy 27BTC via this mining hardware when they can spend $8000 to buy 40BTC via an exchange.

AM I missing something?

I bought some hashing power on cex.io last week. You could have gotten them at 0.07BTC if you were lucky and quick. There was plenty of hashing power at 0.08-0.085. Nobody wanted it.

Even now, you can get 400 GH/s for about 40BTC without doing anything or waiting for your boards. Not to mention the PSU, hosting and cooling.
Just buy, and you get ghash.io worker with the corresponding hashing power working for you immediately. You can redeem your hashing power for the actual hardware, again, immediate delivery.

MBP really overpriced the October deliveries. I sold my two August kits for 7.8 BTCs (~65GH/s).

So h-boards are back in stock with 250 count... where's the shipments?

Wow, I literally hit Save about 30 seconds ago...yes I have a few extra H-cards of the old type that arrived. Since I don't the M-boards for them, they are only useful for filling out your V1 or V2 M-boards. Buy them now, and they will ship immediately.

Production is cranking for the next-gen boards, but I haven't received any shipping notifications yet. I expect to see something in the next day or two...when product is on the way I'll give an update.
