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.

Edit : Martin is more than welcome to remove my posts once he has provided my tracking number, to reduce the clutter in the thread.

Tracking Received, Thank you

feel free to clean.

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

Morning, if can you tell me reported speed with nanos?
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

Yeah
