-====== Device overheating message ======
-//, 2013/06/11 09:46 //
-Hi, I'm running my FPGA 1.15b + experimental board 1.3 on Linux.
-I was able to upload the firmware to eeprom with the following command:
-vp@deathstar:~/Downloads/ztex/ztex/java/FWLoader$ sudo ./FWLoader -ue ../../../btcminer/ztex_ufm1_15b1.ihx
-Firmware to EEPROM upload time: 2581 ms
-the ihx i've got from btcminer, because I wasn't able to find it in the Download package offered in the download area. if its there, please advise me. The .bit file i couldnt find it as well. do I MUST to generate the bitstream or do you have it download?
-then I tried to run it as:
-    java -cp ~/ZtexBTCMiner-121126.jar BTCMiner -host "http://mint.bitminter.com:8332" -u foo -p bar -d 0
-    ztex_ufm1_15b1-04A39E20AD: New device: bitfile=ztex_ufm1_15b1   f_default=184.00MHz  f_max=224.00MHz  HpC=0.5H
-    ztex_ufm1_15b1-04A39E20AD: MAC address: 0004a39e20ad
-    Warning: Possible Bitstream CRC error: INIT_B_HIST=111
-    ztex_ufm1_15b1-04A39E20AD: FPGA 1: configuration time: 231 ms
-    ztex_ufm1_15b1-04A39E20AD-1: New FPGA
-    ztex_ufm1_15b1-04A39E20AD-1: Set frequency to 184.00MHz
-then after that It just quits with the message:
-    ztex_ufm1_15b1-04A39E20AD-1: Using LongPolling URL http://mint.bitminter.com:8332/lp
-    ztex_ufm1_15b1-04A39E20AD-1: Set frequency from 184.00MHz to 176.00MHz

-    ztex_ufm1_15b1-04A39E20AD-1: Set frequency from 176.00MHz to 168.00MHz
-    ztex_ufm1_15b1-04A39E20AD-1: Error: Hash rate drop of 8.7% detect. This may be caused by overheating. FPGA is shut down to prevent damage.: Disabling device
-if i set the BTCMiner parameter -oh to 1.0 I don't get the CRC error but the frequency goes down like:

-What are the possible causes? As power supply I'm using this one from Conrad http://www.conrad.de/ce/de/product/512898/VOLTCRAFT-FTPS-12-60W-Tischnetzteil-Getaktet-Schaltnetzteil-12-VDC-5000-mA-60-Watt?queryFromSuggest=true
