Did you get my email Marto?

Hi Marto,

Very satisfied customer here, shipment was faster than i expected and board is working fine now.
I did buy an TPlink router and applied image from your website.
Both (7 and 24 GH/s) are working fine now.
It was very hard to get them working under windows or ubuntu, but with tp-link router it works as it should be.

So thank you for good software and miners.

Regards

Wilco

You guys must be making fuckall now with the BTC difficulty being so high? When I ordered 2 Hex16Bs, i stood to make 2.25 BTC when I checked in LATE november. If I checked now, I could make just over 0.6 BTC a month... absolute joke lol

That's just the way Bitcoin is. You get screwed by any delays. Marto seems to be improving, I got my HexA81's on time, at least. Hopefully one day the market will get over MtGox and the BTC will be back at $1000.

If anyone in the UK wants to buy some Hex16B's send me an offer. I've got 6x doing 270GH for 415W, fitted with quiet fans, I'll even throw in the PSUs, Hub and TP-Link miner if someone can take the whole lot in one go.

God dammit Marto, you said you will give me my refund last week! Where is it?

After I waited for 5 months (for nothing), is it now too hard for you to make a few clicks and send my money back? Are you TRYING to make your business look bad? I honestly don't understand you.
If this takes any longer I'll demand more due to interest rates. You are holding my money for 5 months now.

Confirmed.

Let me publicly acknowledge this: marto74 has given me my full refund.

Some advice to people doing business with TechnoBit/Marto: be patient. VERY patient. Don't be surprised if it takes weeks to get a reply. If all else fails, use this forum to communicate.
Some advice to Marto: DUDE! TALK TO YOUR CUSTOMERS! I can't stress this enough. Answer their emails and contact requests. People don't hate you, they just hate to be left in the dark, because they don't know what's going on. Just answer their emails and everything will be fine. I know you're mainly a tech guy, but communication with customers is EXTREMELY important. Hire some student to answer emails for 1 hour a day. That's all you need. You wouldn't be having any of these complaints if you just talk to them.

That is all. Thank you for keeping your word, even if it took so long.

Marto,

I'm having an unknown issue with one of my technobit hex 16b. It is reporting a problem connecting as a usb device. I'm unsure of the cause, it just stopped working.

I'd like to try to fix it, but if I cannot, may I ship a non-working unit to you for repair?

Thanks!

Batshark

Edit: Got a response through technobit.eu, I'm going to ship 2 units, one unit does not work, the second is working, however there are burned out components on the bottom of the board.

Edit Edit: I'm only going to ship one unit, the one that is completely non-functional Thanks for quick response by the way!

hello all
     I have 2 miners running off of a raspberry pi one is a hex16B which runs around 44 ghs

     The other is suppose to be a Hex16A2 which should run at 24 ghs but I set up voltage to 1500 and options to 16:540 yet it seems to only manage around 7 ghs  1500/705mV not sure how to tell if this is a 16A or 16A2

 Thanks for any help or advice

Hey marto74 how long until we see some gen2 bitfury boards running?

I don't think a 25% improvement per chip is enough to make them competitive unless they cut their price so Marto can put 32 chip/110GH on a board or slash the 16 chip board drastically. Really disappointed they are still at 55nm, could have put 40nm in the same package.

The 4x A1 130GH/s board looks the best right now (8x A1 has cooling requirements not suitable for home use!).

FriedCat is working on a 40nm chip that might be competitive. Was talking similar specs to A1 but at 40nm should make it much cheaper than 28nm.

Wrong setting. It's should be --hexminerc-voltage 1100 --hexminerc-options 16:1500

Check the asics, Gen2 is Avalon A3255-Q48.

[GayEddie]

Also it seems to have one blinking red light

I have been putting hexminerb 900 hexminerb 16:540 then hexminera 1500 hexminera 16 540 so your saying leave off second part and add  --hexminerc-voltage 1100 --hexminerc-options 16:1500

Sorry Zich I am a bit off a noob

Did you own HEX16A too? If not then no need to add command --hexminera-voltage 1460 --hexminerc-options 16:480
Just use:

Code:

sudo nano ./cgminer --hexminerc-voltage 1100 --hexminerc-options 16:1500 --hexminerb-voltage 900 --hexminerb-options 16:540

I see they priced the BitFury 2 test chips at €5. 32x €5 = €160/$220 for about 110GH/s, expect double for other costs and Martos time, would make them about $4/GH per board.

I was thinking the same thing. PCB and components do have a fixed cost that will influence the final cost per GH/s very much. Having a 2.5GH/s chip at ~0.7W/GH pushes the 3$/GH limit very much. Paying for more per GH/s is just throwing money on the window. Let's hope for a dump price for the chips!

What's the min PSU needed to run 3 boards?

My 3 bitburner fury's are running on a corsair 750, and I was thinking the technobit boards might have similar power requirements.

[marto74]

3 boards hex16b will draw up to 3x75W
