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?

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.

Hi,
after testing the Ztex 1.15x on CGMiner (and really not liking the experience.. unfortunately) i tried to get back on BTCMiner but i have a problem:

Code:
C:\ztex>java -cp ZtexBTCMiner-120703.jar BTCMiner  -host "http://de.btcguild.com:8332" -u Nachtwind_fpga -p yup -f ztex_ufm1_15d4.ihx
Error: Device lost after uploading Firmware: No new device found

I cant find a way to revive it for BTCMiner... CGMiner still works "fine" (as in the limits set by CGMiner) though..

Any ideas?

Did you change the usb driver back ? IIRC you can do that with Zadig.

Ok, changing the driver to libusb did the trick. Thanks.

works great - i have arround 200 MH/s more submitted shares with 2 quads.

The temperature limit is set using the parameter -t, e.g. -t 65 sets it to 65°C. If this temperature is reached the FPGA is shut down.

Up to 70°C (default temperature limit) is ok. But try to stay below 60°C in order to achieve the maximum performance.

See https://en.bitcoin.it/wiki/Target, if pool difficulty is > 1 it only submits shares that met the target. (By default all shares smaller then the maximum target are submitted).

Hi,

I've integrated the recent changes into my httpd version of BTCMiner.

Source is online here: https://github.com/gr0bi42/BTCMiner

Made some changes regarding target checking too, although there are still problems with pool.itzod.ru.

Added a cool looking JSON based Webinterface. See photos below.

Precompiled package is available here: https://github.com/downloads/gr0bi42/BTCMiner/ZtexBTCMiner_gr0bi42_20121108.tar.bz2

See the README for further infos.

Happy mining  Smiley

grobi42: Thanks you for the fancy webinterface. I am running the miner on a QNAP NAS. But the Webserver doesn't start up. Are there any logs where I can see why ?
