1 TH/s-miner with only 16 GH/s

[rezilient]

Could you have gotten one of these: http://bitmine.ch/?p=5178

Nope. I've ordered with Bitmine (yeah, beat me), so I would recognize them :-)

Hello.  Any luck with this?  One of these machines I ordered is showing only 600-700 GH/s on BTCGuild dashboard.  The machine itself thinks its doing 936 GH/s.  I have the minimum difficulty on BTCGuild and the machine set to 1024.  Thanks for any help or pointers.

Hi,

I fixed this error on my machine.
I have found out that you should never use 1024 on the machine side.
Normally CGMINER and pool communicates about best difficulty,  and to start at highest level is a very bad idea from machine side.
Set the machine to 256 (default) and the it works flawlessly.

If you wanna raise difficulty set the minimum diff in the pool. The parameters is called "minimum difficulty" and the difficulty starts at the value you choose. If yu choose 16 it will very soon automaticly raise.
In my 1 Th machines i use 1024 "minimum diff" and in my 200 Gh machines i use 512 or 256.
It doesnt effect the hashpower that much but the 1 Th machines works more stable with 1024 and it also minimize network traffic.

So problem solved :-)

Hi Urbie.  Thanks for the advise. I tried what you said, but alas still having troubles with my machine.

You can see in the pic, error rate on module #4 is very high, and therefor the speed is only 700-800 GH/s.  Speed on module #4 is obviously wrong.

Also I have a customer with another machine where the module #4 is not showing up at all, so he's only getting 650-750 GH/s.

Any thoughts?

I had some problems the first start and when i changed IP-adress.
Sometimes Asic 4 is not showing up for me, but perfoming a coldstart normally fix it.
You can also check the lights on each asic blade, there is around 10 green leds in a row and they should be green. If some of them are red that means that some chips are offline because of a failure. It could happen when power is to low or something else spoky :-)
Just restart the machine and hopefully all go green.
I have this problem on another miner, sometimes i need 3-4 restart until its all green.

If the problem persist it could be a fault in the machine and you need to get it fixed.

Ohh by the way
What is the temperature on that board (nr 4)?
Check the other values and see so there isnt any strange things that can lead you in any direction...

In 10 hours i am in front of my machine again and can compare numbers...
