I recheck 2 PSU and lots of Cables

Switch to 250/100 and so on dosent work

Greetz Glen

Do as follows
1. Unplug USB
2. Restart cgminer
3. Wait for it to start
Plug USB cable
If you are on tplink USB hub is a must
Post Dmesg output also will you?
Set it to 240/970

oops many HW Errors, i restarted the Pro under Windows and try to go higher with Voltage

Damn how i can get add am JPG here ?

What is your voltage and clock?
Try it with 230/970
For some reason it refuses to start when voltage is low. You can go up to 1050 mv no problems do not be afraid
And use tplink or Linux if you can. If you insists on windows reinstall USB driver

i tried diff Voltages
910,950 etc

I do not know what else to tell see if there are some fuses?
I am not a hardware expert though. Sorry

Hi everybody .

now its the sadly Day for me, cause my Hex8 - 130 dont wont to hash anymore.
Whats happend ?
Nothing. At the Morning i looked at the Miner and everything was OK.
Later on it shows no Hashrate anymore. Ok, Server or other Things down.

BUT !

it always Shows 0,800 V ( settings = 240/900 till start )

Reboot Raspi , PSU Change , Cable Change , disconnected 100 Times.
Then start over to normal Windows PC .
Hex Miner Programm starts the same when i get this Board. No other Things changed. 100 Times changed differnet Settings , HW Find and up

But no Hashes anymore.

Power LEd = on , USB LED = ON
2 LEDS green
Chips Cold, Fans OK

Any Hints ?

Or its going to be RMA ?

Greetz Glen

Try it at 950 voltage.

The diference is comming from the diference in chips.
We do not favor any body in terms of boards performance.
What we do is to check on a test software how many engines are working.
If there are more than 20 dead engines on a board it is stoped and returned for repair.
Also if there is a single chip with less than 25 engines we stop it again

Thanks for the reply marto74

Apologies if I came across as accusing you of something. Your customer service have been top notch.

But I do think that seller is pushing the marketing boundaries when selling HEX8A1 gear as 270GH. Further, is seem he made or it reads like he got a better deal on h/w performance. Anyhows, not your problem.

On another matter, any plans on 40nm Hammer ASIC from Spondoolies-Tech or their 28nm RockerBox ASIC??

Cheers,

Thanks the question!

Hub is here. Yesterday I've restarted it and working since then.

Now i won't touch until it stops, so I can post what dmesg shows, and I'll make the hub then.

You had a good carma, the miner is afraid..

It will not stop Wink

Ops i have not said it Lips sealed

That is how tplink works when done things are done right Wink

Non stop since last cgminer upgrade

Hey marto74,

Would you care to comment on the quotes below? Particularly, aopa38's claim that different batches will perform differently? I understand ASIC chips have grades and h/w performance will vary between units; But do you grade your h/w and how is it distributed to your customers? Do some customers get favouritism over better performing h/w? How does one get the cream of the crop h/w?

aopa38's 2nd claim is to run the HEX8A1 at 270GHs. Presumably this is Turbo, Turbo Mode. Is it recommended to run these units at 1050V? I know the numbers are possible, i've tried them, but the results are some what disconcerting that I ran my units at a lower V and F and still manage to get just under 260Ghs. Of cause I'll be happier running them at 270GHs if you say its not a problem.

I'd like to see what h/w error rates you are getting when you run them at 270GHs. Please do tell

Technobit advertises 260GHs "Hash rate - about 260 Gh/s overclocked in turbo mode" (http://technobit.eu/index.php?id_product=63&controller=product&id_lang=1) and you are saying "270 Gh/s overclocked in turbo mode"? So is this like turbo, turbo mode?

I hate to be a troll but I am really not; Cause really, you are just exaggerating the facts to make financial gain. That's dishonest Angry

Prove I'm a troll and show me pics of you running those boards at 270GHs with min. H/W errors. Or you can tell me what freq and a V settings you are using to achieve those Hashing rates.

Maybe it's cooler in Canada now then it it is in Australia. But iirc, it's Spring there atm?

Cheers,
QG

It depends on which batch of boards you get from Martin at Technobit. The difference in the A1 chip between batches in particular is quite big.

As for settings, 270 / 1050 will normally get you 270GH/s although in the past we have had some boards which can do it with less voltage.

We run over 200 Coincraft boards in our converted warehouse with an ambient temperature of 28 C. They have run stable since the start of March. I'll update the thread with CGMINER stats ASAP.

Cheers,
QG

I have some HEX8A1 130 and I was planing to buy more mining power, and now I see one technobit web page the Avalon Gen 3 based miners, and I dont know which one is better, if this one or the hex8a1. The price is lower but the hash power is lower too, maybe the difference is the power needed. I dont know which one to buy.

I don't think the avalon chips are better.
+ if you have already HEX8A1 and you are happy with it, continue with the A1

I see Ioshia gets the "good" chips Huh

Not he chips dude the setup and the software Wink

Any way cgminer-api stats | grep En

Would give you how many engines are working
it is normal to have some dead ones. That is the chip quality
so check this and then we will talk again ok Wink

And besides i am not undervolting as you can see Cheesy

Post your cores count voltage and clock and we will do the math it is easy Cheesy
