Danke für die Rückmeldung und die reibungslose und freundliche Abwicklung  Viel Erfolg beim Minen ;-) |

Someone told me it is. Like I guessed above, the HW error rates are absolutely okay because that's the only way for CGMiner to test if the board can handle the requested speed.
Please correct me if I'm wrong...

Gut gesagt  Nun ja, bei Interesse, einfach melden. So eilig habe ich's mit dem Verkauf auch nicht. |

Ja, kann Deine Argumente nachvollziehen, aber noch habe ich keinen der ASIC's wirklich in freier Wildbahn gesehen und was die 5970er (oder 7970er) angeht, nun ja, ich habe erst letzte Woche meine dritte davon "zu Grabe getragen" da ich vermutlich immer ein wenig Pech mit der Langlebigkeit der Spannungswandler hatte.
Wie auch immer, falls doch noch jemand Interesse hat, bitte melden.
Aktueller Preis liegt jetzt bei 620,- EUR.

Sorry, habe mich wohl beim Preis etwas verhauen. Meine jetzige Vorstellung ist 780 EUR 620 EUR.

Yes, already did this at the very first time it started making these noise. The fan is working again ... but the first GPU is dead and therefore I have no chance of controlling the fan (because it seems that it can only be controlled by the first GPU).

Yes, I doubt that but I always thought that the entire card will die if the master GPU dies... So maybe I should try to flash a master BIOS to the slave GPU in order to get at least the fan control back? So I would effectively convert my 5970 to a 5850  |

At the moment, I'm still searching for a system which can handle such a card ;-)
I've already tried swapping both cards (or running with just the defective one) but the effect remains the same: Only one GPU in the device manager (and GPU-Z) and the monitor only displays a picture if it is connected to the 2nd DVI port, even at booting stage!
I will try an alternate operating system as soon as possible but at the moment, I also doubt it is some kind of BIOS problem. A long time ago, I flashed the card (both GPUs with the according master/slave BIOS) in order to get better OC possibilities. Maybe there went something wrong ... but the card's function wasn't effected in any way.
There is one thing which sounds a little bit curious to me:
I can't control the fan speed of this card and I guess this is because the fan is strictly controlled by the master GPU (which isn't visible to me). But the automatic fan speed control is still working. I can clearly hear the fan spinning up when there is high load on the GPU.
I mean, as far as I know, both GPUs are connected to an internal PCIe-Bridge which is then connected to the PCIe-bus of my system. So the 5970's internal bridge would enumerate both GPUs at boot time, just as my system does with regular single chip GPUs, right? So maybe the 1st GPU just isn't responding fast enough (or with the right devid).
But how could I reset or reflash the BIOS if I can't "see" the card?

One of my two 5970 is driving me nuts: A week ago, CGMiner started to crash randomly. I figured out that this was caused by "GPU0" which is the master GPU of the 1st 5970 (ATI Reference card). I got the entire system working again by lowering the freq to 600/300 and setting the intensity to 5. Everything just on this core, of course. The remaining (slave on this card and both on the 2nd card) were still mining at 830/300, intensity 8. Temperatures were all in range (~80C on the first and ~65C on the second card which uses an Arctic cooler).
So far, so good but after a few days, the fan on the first card started to produce a heavy noise and I instantly saw a decrease in fan speed and of course an increase of temperatures. The system crashed a few seconds later. I was able to get the fan working again ... but now the first GPU of the first card disappeared in the device manager (Win7 x64). The 2nd GPU and the entire 2nd card are working perfectly. Even the two red LEDs light up for a second when starting the system.
Do you think there's anything I can do?
I thought about flashing a modified BIOS which will decrease the clock just at POST because I think, the first GPU is failing at this point. But RBE doesn't recognize the first GPU ... just the slave one :-(
Maybe someone has an idea...

Whew, up and running again. Glad to see my wallet is still alive and my offers are on schedule...

Unfortunately, Bitmarket.eu is unreachable since midnight (August 30th). I hope, my wallet is still valid  |

Are there any rough estimates on how many BTCs to expect per GHash a day?
I know, it depends on many factors but I just want to cross check that I'm on track.
At the moment, I get around 1 BTC (+/- 0.3) per day with a hashrate of about 3 GHashes/sec.

I've recently started mining with a ZTex 1.15y (quad FPGA) using CGMiner. As far as I can tell everything works fine (2 chips run @ 212MHz, 2 @ 216MHz) but I'm quite unsure about the stats:
After running nearly 4h, each FPGA showed about 4% rejects and three of them had about 150 HW errors. One surprisingly had only 15 errors. I don't know how to deal with these errors because I haven't seen them in the past on my GPU rigs...
Is this a normal behavior because the chips are simply regulating their clock speed on high error rates or should I check my setup?

Danke an chefnet ... mein Quad ist angekommen und scheint auch zu funktionieren ;-)
Zwei kleine Fragen hätte ich aber noch:
Ist es normal, dass CGMiner nach knapp 1h Betriebszeit bei 3 FPGAs etwa 40 HW-Errors und bei einem <10 anzeigt? Ich tippe zwar darauf, dass dies ein normaler Indikator dafür ist, dass die FPGAs jetzt runtertakten, aber ich würd gern noch eine Meinung dazu lesen.
Wenn die Prozessoren nach einiger Zeit von 220MHz wieder auf 216MHz heruntergehen, dann heißt das doch sicherlich, dass die Kühlung noch nicht okay ist, oder? Was wäre denn das Maximum an Taktfrequenz was schon erreicht wurde?
Gruß,
ox

Hi!
Ich benutze seit einiger Zeit Anubis um meiner fünf Miner (insgesamt acht GPUs) zu überwachen. Jetzt ist mir aufgefallen, dass bei drei Rechnern die Werte bei "Discards" (basiert wohl auf dem "DW"-Wert in cgminer) über 50% betragen. Bei den anderen sind es nur ca. 5%. Stales, Rejects, Get Fails und Rem Fails sind bei allen Miner gegen 0%...
Leider konnte ich nicht wirklich feststellen, woran es liegt oder was es genau heißt. Das bedeutet jetzt aber nicht, dass 50% der Shares für den Mülleimer sind, oder?

Hi! Hat jemand Ideen, was man für ein Gehäuse für das ZTEX 1.15y Board benutzen könnte? Idealerweise sollte es groß genug sein, das 12x12cm Board inkl. der vier Lüfter und evtl. noch einen Gehäuselfter aufzunehmen. Das Platinenlayout ist unter http://www.ztex.de/usb-fpga-1/usb-fpga-1.15y.d.html#fd zu finden. |

Interesting point. Thanks for that!
Nevertheless, now I'm using the Anubis frontend and it already has exactly this functionality built in ;-)

Does anyone know if it's possible to query information of my wallet outside the original client (bitcoin-qt)?
I'm looking for an easy way to access current bitcoin amount in my wallet and optionally the transaction log using either ODBC or ADO.net.
Thanks for any help...
