Windows 7 out of the box with The newest SDK and Catalyst drivers, 5800 and 5900 series ATI cards cannot do that.
Thats your problem. Use 11.12 drivers and 2.5 SDK. Nothing is "modded". Just use software that is known to work. |

SIX is the max number for windows 7.
not true. Yes True. I personally have multiple 5870s and 5970s. 5970s are dual GPUs. I have motherboards with 6 PCI slots. I can install six 5870s. Or I can install two 5970s and two 5870s. I cannot install more than three 5970s. I can not install one 5870 and three 5970s. I have personally verified that you can not install more than 6 GPUs with windows 7. I have looked this up online to find that Windows 7 maxes out at 6 GPUs and Linux maxes out at 7 GPUs. If you disagree, then explain. I disagree with you. This picture is all the explaining that is needed. Yes this is windows 7.  |

Pictures please. Do you have a model number too? Brand? Cmon, details!

Generally a residential wall outlet is rated for 180VA for calculation purposes. .... Max total for each 15a circuit is 1800va.
Wait, so the circuit is rated for 1800W, but each outlet is only rated for 180W? That doesn't seem right...  He typo'd. Me meant 1800VA. He missed a 0. Also, some people might wonder what the difference is between VA and watts. An AC circuit is a sine wave. When you measure the volts of some AC with a multimeter, the displayed volts is the peak voltage. The voltage isn't always 120v. It goes up and down in a regular fashion 60 (or 50) times a second, like a sine wave. Now, take a device thats 1500 watts (12.5 amps @ 120 volts) and tries to pull a significant amount of power while the sine wave is not at or near a peak (say when the wave is at 60 volts instead of 120), it will draw more current to compensate (twice as much in this scenario). So while the power consumed will continue to draw 1500 watts, it will in fact be drawing 25 amps, or 3000 VA (!), which will easily trip a breaker, or melt wire insulation if for some reason you aren't using a breaker. The way this is gotten around for AC to DC, like computer power supplies, is active PFC. It aligns power draw with the peaks of voltage, so your VA will always be very close to your watts. Kill-a-watts measure both watts and VA. Try plugging in an old, budget, non-PFC computer power supply and load it up and compare watts to VA, and do the same with a newer power supply with active PFC. |

Looks like i missed the party  Not quite. I have a LOT more cards sitting idle in the basement right now. I'm just taking a break before I take pictures and list them. Can you give me an itemized list of what you are selling. I might be able to take a lot of it off your hands if you are willing to give a good discount for one large purchase. I'm still in the process of testing my equipment. Generally, 7970s expect $290 each, 5970s $250 each, 5870's $120 each, mobo combo $100, power supplies $160, risers $1.50, and pci-e power plug splitters $2.50. Shipping is not included. If some GPUs are malfunctioning, they will be marked down, but it requires time to know if they are malfunctioning. If a GPU passes a 5 minute pass of OCCT:GPU:3D with no errors, 5 minutes of furmark with no visual artifacts, and a 3dmark 2011 benchmark without artifacts/crashes, it's marked as GOOD, but I maintain that I make no guarantees, all equipment is sold AS IS, and all sales are final. |

If you are placing these all on a USB hub, its entirely possible the hub cant handle it. A poor quality hub will exhibit any of the symptoms: ASIC not detected at all in mining software; ASIC appearing to hash but never submits shares and the ASIC itself is relatively cooler to the touch compared to the other ASICS submitting shares; ASIC spams hundreds of HW errors every second; A very strange hashrate like TH or EH. GH is less suspect and could just be bad timing estimation by mining software. A poor quality/low output power adapter will exhibit symptoms such as devices in the mining software inexplicably resetting or disconnecting and reconnecting.
I suggest plugging in your ASICs directly to one of the USB root ports (not using a USB hub) to see if the symptoms go away. It's also possible that the ASICS themselves are flawed, but lets rule out the USB hub first.

4x used 7950 = $900 (225 each)
used power supply = $180 (seasonic), $160 (anything else)
SSD = $40
motherboard + cpu + ram = $125?
rack (?)/case = $25
$1270.
You're asking a pretty hefty premium.

A quick phone call and teamviewer session and I've gotten him up and running! |

I've mined on up to 12 5970s with unpowered 1x > 1x risers over the course of 1.5 years. No problems with them.

Judging from the posts in this thread, none of you except the OP actually have owned a 5970. Luckily for the OP, I have.
The fan can only be adjusted from the second GPU. The fan setting in the first GPU is a dummy setting (always shows 30%, can't change it. If you try to, it will fail). The second GPU is the one that controls the fan. Bear in mind that fan control on the 5970 is a little wonky. Speeding up is usually instantaneous, but slowing down is done slowly, so if you try to decrease fan speed and it doesn't seem to be working, give it a minute.

Hi. It was very simple for me to get my block erupters working. First step: Download and install the CP2102 driver http://www.silabs.com/Support%20Documents/Software/CP210x_VCP_Windows.zip and extract it somewhere. Run the CP210xVCPInstaller_x64.exe if you run 64 bit OS, and CP210xVCPInstaller_x86.exe if you use 32 bit OS. Second step: Download BFGMiner 3.1.1 Third Step: Add this to your command line. The -G will disable mining on all GPU's. The "-S all" command will enable mining on all devices on com ports. Here is what my full command line looks like. bfgminer.exe -G -S all -c \\Ssateneth-pc\d\minersettings\btcconfig.conf The "-c \\Ssateneth-pc\d\minersettings\btcconfig.conf" is just a config file I load that contains my pools and other non-device specific settings like no stratum, api access, etc. If you don't use a config file for pools/settings, then instead replace that part with "-o http://pool:port -u username -p password" where pool is the pool URL, port is the port, username is the username, and password is the password. You should be mining away then!  Here's payment address. 1BXNapSrzTSfmqSD63e49eh2JvDkeotCxt If this is still above and beyond you, I would be willing to teamview or vnc to remotely fix the problem. |

*Sigh* Bunch of trolls. Go back to your corner of 4chan.

Well if you read the entire eBay description then you would know.
The only part that remotely mentions italian anything, aside from referencing itself, is something about some grapes. My question still stands, and give me a direct answer instead of pussyfooting around. |

what makes it an "italian special edition"? are you just trolling? making shit up? or does it run faster? have special decals? wtf?

Don't know why popmoney wont let you add your bank. Mine wasn't listed but they let me add it anyways. I think the thing where it shows all the banks is only if that bank natively has popmoney support. You can still do popmoney with banks that dont specially support it.
Lets move this to PM.
Edit: It's been a very busy night! Lots of stuff are sold! I will have much more merchandise sometime in the next week or the week after with many AMD reference 7970's, 1x > 1x open ended risers, maybe some motherboards/CPU/Ram and maybe some power supplies. Stay tuned!
