ztex any plans for stratum for BTCMiner?

The bandwidth requirement of your ZTEX cluster is a few hundred bytes per second. Your Internet connection should be able to handle this.

Implementation is not planned within the next release (but maybe later).

In the meantime you could use slush's Stratum mining proxy.

At difficulty=1 the get-work frequency is approximately twice as high as the submit-work frequency. I hope this is not considered as flooding too.

Ok, getwork is slowly going to die. I'm not sure if you're aware of Stratum or GBT, but there are no "getwork requests" in these proposals at all. And with faster miners (or big mining operations based on ZTEX), submitting diff1 shares really may look like flooding. Where's the sense of sending 10 diff1 submits per second?

Check the PSU. They often die slowly / become unstable over time if they run permanently at high temperatures (liquid electrolytic capacitors).

What effect does a dying or unstable PSU have? Dropping voltage, interruptions, anything else?

Liquid electrolytic capacitors loose their capacity over the time if they run permanently at high temperatures. This causes voltage drops or interruptions at the load step after configuration. Possible effects are:

* Full loss of configuration ==> bitstream upload errors
* Partial loss of configuration ==> FPGA delivers wrong results ==> dowclocking
* device disappears from the USB if PSU interrupts (e.g. due to undervoltage or overload protection)

The same effects occur is PSU is to weak or output capacitance of PSU us to small.

If Inaba means that BTCminer does not support difficulty >1 checking he is right. This is obsolete because it is done by the bitcoin server / pool.

You probably cannot be more wrong with this. All pools were working with diff1 shares for almost two years, but with rising hashrates of miners, submitting diff1 shares is wasting of resources - too much traffic and pool load for no reason. So all modern pools are slowly implementing dynamic difficulty for their workers. Submitting low-diff shares to the pool may be considered as a flooding and may be a reason for ban.

Please add checking difficulty for next release, it is literally five lines of code.

At difficulty=1 the get-work frequency is approximately twice as high as the submit-work frequency. I hope this is not considered as flooding too.

How do you enable backup pool with BTCMiner?

it should switch to your backup pool, if you enabled one in your config?

@Ztex
Yes my power supplies died ore wer slowly dying. After six month of contious mining.

I'm still getting (not your fault):

001-0: ztex_ufm1_15d4-04A346E2B9-1: Error: connect timed out: Disabling URL http://pit.deepbit.net:8332 for 30s

But after a few of these in a row the whole cluster shuts down (problem with BTCMiner)!?

changed the power supplies.

and now im testing if it works ....

i really do have to make some connectors for my pc power supply. Couldn't be that hard to do it myself?

i dont need to reset the boards. they are just dying one by one.
Sometines a Single FPGA and then two to four. (all randomly x and y boards).

I Checked the HUPS and the Cables ... everything is at least bought from "good quality" vendors (Hubs are from Belkin and trust) cables are shielded etc...

I'm thinking about buying a small Netbook or a router (i have tried TPlink but ddnt succeed ...) that's going to be my miner ...

Looks to me like that software does not support > difficulty 1 shares.

Thats his answer ?

and i'm facing massive USB Connection errors out of no reason (i cant think of one, since it worked flawless for several month now).

My Setup:
A Windows 7 VM on a MAX OSX Mountain Lion Host ( Since i'm totally unable to get BTC miner < or anything else that can mine with OSX> working natively on MAC)

A 7 Port USB Hub.
A Silex SWX2000W+ device Server (All boards connected to this device server)

It worked realy good for at least 4 month now .... All of a sudden, after a small Software update and a brief restart of my MAC all my board are facing massive USB Connection errors ....

If i connect them to the device server or directly to my mac they wont be stable at all. After some time they randomly shut down with libusb connection errors.

--> Im buying a video card tomorrow .... need to ged rid of the MAC / VM solution.

Does it help when you pull the power plugs from the boards and then plug them in again (while keeping the usb cables connected!)?
