Are the H-cards even in stock?

Was hoping to fill out my starter kit but at that price point... yikes.

Got my sept payment. Thanks.

In my last correspondence with Yvonne I was told "here is some issue with a server or some such technical thing so he will make another attempt shortly". I would really like to resolve this now.

End of the month? I'm struggling to understand how distributing 1.25 BTC across 32 orders is requiring months of work. SebastianJu refunded 100's of customers in one day. Come on Dave, just send the payments.

The weekend came and went without a BTC refund for the delayed August orders. We are just a few days sort of a month waiting.

Still waiting.

11.5 BTC

GTA

Looking to sell one of my MBP Bitfury Starter Kits /w Version 2.1 M-Board for 11.5 BTC.

The included H-card runs stable at 35 GH/s with errors less than 4%. I am located in Canada and would prefer to ship to Canada to keep costs low for all involved. I'll throw in two DC fans so you can run it overclocked right out of the box.

It will be a few weeks until Megabigpower ships the rest of its units so get ahead while you can. If we settle today I can run down to the post office and get it in the mail today. Would prefer sale to be completed via escrow (SebastianJu).

I sent my address but did not receive a payment. I'll send it again right now.

Has any one been given a figure on the refund? 10+ days since the initial email from Dave.

Send Isokivi a tip for saving you the headache.

Just took a look at the results from 12+ hours of logging yesterday after pulling chainminer v1.2. The board looks quite stable and error rates dropped significantly (~1% over the entire peroid). I'm looking at 36 GH/s sustained over long periods just dc fans and no heat sinks. I've manually clocked all chips at 54 and have not noted any benefit in using the auto feature in v1.2. Now someone push the board up to 40

Anyone received details on the BTC payments to late august orders? I received an email saying there were compiling options but no details.

Nice bump in gh greaterninja. Glad to see the improvement I saw is not a one off.

Have you tried clocking the chips down? Mine seem much happier at 54 or 53 with the higher voltage. I need a bit of patience with mine as well, it often does not achieve its top end for a few hours.

The in circuit resistance is ~1.18K at room temperature. I've not measured the resistance once the system is up to operating temperature. I've moving air across the board somewhat aggressively to keep temperatures constant and the regulator happy. My digikey order came in today and I'll try to work up some stats on swapping resistors out this weekend. I'm not interested in using the pencil mod as a long term solution.

I'd take a "if its not broken dont..." stance on software changes unless you are having similar bus issues. I was interested in the spi changes (increased speed and reset rate) and have observed a positive increase in stability/noncerate by upgrading. I'll try to do a sensitivity sweep of the reset rate to find what works best for my setup on the v2 boards.

I had to remove the chainminer directory on the MBP supplied sd card as git was not setup on the directory. I then cloned chainminer from https://github.com/bfsb/chainminer and issued a make.

I only have an hour of logs to show here but the standard deviation on my mean chip noncerate has dropped significantly with additional spi resets. The card is consistently pushing above 35 GH/s with a pair of DC fans and a bit of graphite.

NOTE: I was one of the late august orders and received a 4 channel 2.3 M-board. Comments in this post only apply to those with this board or later revisions.

I pulled the latest commits from the bfsb/chainminer last night and have improvement in the stability of my starter kit over the last 12 hours. Error rates have dropped from ~7% to ~2%. More importantly my previous MISO errors have nearly disappeared. The comments on the pull suggest that by increasing the spi reset rate stability should increase. The H-Card is stable at around 36GH/s. If you are going to pull the latest commits make sure to back up your current software AND make sure you have the proper hardware to do so.

I'd like to hear about other experiences with the new spi resets.

They are marked as motherboards and taxed at 100%. I paid $110 on mine as well.

Emails were sent but they did not give a specific amount for compensation. I emailed them last thursday as the email stated and have not heard anything back.
