Martin are you ever going to refund me for my order which was placed on 11th November?

If you also have been scammed by this business go here and make an entry in his TRUST so that others will not be taken in by him.

The scammer marto74 (Technobiteu) has deleted my customer account on Technobit.eu and I got nothing!
Plus I don't received the refund I asked on 2013-12-09 for.

Thanks for the advice, I'll try those settings.
Can it have to do with cgminer or the raspberry?

I guess no

I've ordered and received a couple of these miners. First order was from the "week 1/2 december shipment" batch, the others were from the "december shipment" batch.
From this last batch, one of the miners is acting weird.

It's connected via a molex plug to a Corsair 430CX PSU, no other devices attached to the PSU (so plenty of power I'd say).
Via USB connected to a raspberry, running the patched CGminer found on the technobit site.

When using the recommended settings (1500Mhz, 1.000volt) it starts hashing at 22-23GH/s but after about 2 hours the speed drops to only 6GH/s. Reconnecting the miner and starting it again gives the same behavior.
I've tested some other settings, and the most stable now seems to be 1300Mhz and about 1.2 volts. With this it still drops in speed but it seems a bit more stable (it takes longer to drop).

The fan is blowing and the heatsink doesn't feel extremely hot. Also tested it on another PSU but still the same behavior.

Any ideas?

That sound like over setting on frequency but 1500 is still on stable range. I had similar result while trying frequency 1600 but never happen with 1500.
With frequency 1500 you could give 1100mv.
And You could try frequency 1400 with 1060mv.

I was hoping this could be a thread with information about new products and updates on software and perhaps some guides. But too bad, it's already cluttered with people asking about existing orders.
Can't that be moved back to the thread about the actual product?

With all due respect there is much outstanding business to be dealt with that has not been dealt with in those threads.

I have 32 HEX16A2 boards from Technobit.
What is the best and safest way to power them? I had planned that a PSU CX750 from Corsair would power 10 in my opinion, but it is clearly insufficient.. Sad

Based on CX750 spec, 12 V rail can supply 62 A. One HEX16A2 use about 9 A.
So 1 unit PSU only able to supply 6 board of HEX16A2.
And please noted that one modular molex power cable can only sustain 1 hex16A2.

7 if they run at 92W each. Put I'm pushing it atm. lol

It should be back to normal. No more dupes also the chip1 should be ok of hexa2 Wink

Morning too loshia Grin

Yes, nanos speed back to normal Cheesy

But i can not run it along with other in TL-MR3020, one nano hash rate become low after few minute. Maybe hub issue Cheesy

Yup, no more dupe & chip1 is hashing normally Grin

Super we will get back to nanos when there is a time for that.nano code is very aggressive and that is the main reason it to break
I do have two nanos + 5 hexa on single tplink and never had an issue there

Marto, trolling is one thing from no apperent reason, however some of your costomers have indeed legit claims and no other way to get issue fixed. If you continue with delay and ignore messages, then this will happen again.
It looks bad on you really. Remember, you have make a wrong first, did not do what you promised and ignored issues.
Fix this so everybody can move one. If user has a legit reason to be upset because you ignore him, why you think hes trolling and continue to sturb the issue. I am sure that mods would remove trolling post withot backing up their claims.

Its not about winning. You have obligation to your customers and that is all. You just can not say, oh, i wont issue refund becasue of numerous angry post of users who has legit reason to be upset and angry.

Nope. You had your chance. I should have received the boards by mid December 2013. I'm not putting 42Gh/s on the network @ 600W at that difficulty.

Assuming that you have 6 boards and shipping is imminent I would be willing to buy your order for say 0.35 BTC on the condition that Marto can combine the shipping at minimum extra coast and in reasonable time.

I know that's not what you paid but we have all lost here.

Your boards are assembled and packed.
If we try to disassemble the chips we can destroy them.
And do you know when the chips were received here?
And do you understand that PCB are populated in batches?

SO shipment tomorrow and no refund.
You can start trolling like the other one too.

Best Martin

P.S.
I checked your order
You paid only 2 EUR for packing.
Your boards are about 4 kg package.
Please organize your transport
You have our shipping address it is a pickup too.

Marto please confirm that are boards have NOT been produced yet.

Please confirm to the best of your knowledge when you expect production to take place.

Please be honest..

Will you provide answers here, that you have ignored in your other threads.

All left Hex16A are packed
to be shipped tommorow
This is except orders got in January

Not acceptable. I asked for refund. I want my chips back AND bitcoins I paid you AND postage. I mailed my chips back in 2013-11-04! Now they are useless pretty much.

Now, if this gets deleted - I promise to spend a bitcoin or 2 on google ads to make sure that everybody knows what technobit.eu is and how good their customer service.
