I am getting more than double the advertised hash rate. I have not tweaked them. This screenshot was 8 hours worth of mining. You can downclock them if you dont want HW but for double the hash and accepted shares i run them the way i got them. People have reported they get hot. I have a 10 inch box fan on mine. They all run cool. I can include the fan if you want it.  Note that the actual hashing rate is 2.695 GH/s as stated there, or approximately 335~MH/s per stick. There's no 'double the advertised hash rates' here. I vote we give this guy a scammer tag or at least a warning under his name. He is trying to sell something he possibly doesn't have and reporting that they are magical with double the hash rate. |

Thats fine i have nothing against you or your opinion. The truth remains. I gave this man 19.90 BTC for miners. He didnt deliver. Instead he sold them for profit using my BTC. He is wrong. If it was your money ou would also consider that shady and bad business.
Care to comment about: I have a non-cooperating buyer who has wasted countless hours of my time and will not sign a message no matter what. |

I have the exact same issue with all of my rigs, but have found that it is only with Windows.
As an example here are my rigs with 7970s. Each has Windows 7, afterbuner 3.00x beta 10, catalyst 13.3, + the following:
Rig 1. 2x7970 - ASRock OC Formula, 2500k, 8GB Ram, SSDs, + 1000 watt PSU
Rig 2. 3x7970 - ASRock 970 Extreme4, Sempron, 4GB Ram, SSD, + 1200 watt PSU
Rig 3. 2x7970 - ASRock 970 Extreme4, Sempron, 4GB Ram, SSD, +1100 watt PSU
These rigs have unfortunately had 7970s shuffled between them too many times due to hardware related issues.
Rig 1. For comparison (2x Visiontek)
1090mv / 1080e / 170m = 649.x Mh/s per GPU
Rig 2. With 4x7970 (2x Visiontek, 1x Powercolor, 1x Sapphire)
1169mv / 1110e / 170m = 645.x Mh/s per GPU (Visiontek)
1094mv / 1050e / 170m = 611.x Mh/s per GPU (Visiontek)
1056mv / 980e / 170m = 568.x Mh/s per GPU (Powercolor)
1169mv / 1110e / 170m = 645.x Mh/s per GPU (Sapphire)
Rig 2. With 3x7970 (2x Visiontek + 1x Sapphire)
1169mv / 1110e / 170m = 659.x Mh/s per GPU (Visiontek)
1094mv / 1050e / 170m = 623.x Mh/s per GPU (Visiontek)
1169mv / 1110e / 170m = 659.x Mh/s per GPU (Sapphire)
Rig 2. With 3x7970 (2x Visiontek + 1x Powercolor)
1169mv / 1110e / 170m = 652.x Mh/s per GPU (Sapphire)
1094mv / 1050e / 170m = 619.x Mh/s per GPU (Visiontek)
1056mv / 980e / 170m = 585.x Mh/s per GPU (Powercolor)
Rig 3. With 2x7970 (1x Visiontek + 1x Sapphire)
1094mv / 1050e / 170m = 621.x Mh/s per GPU (Visiontek)
1169mv / 1110e / 170m = 656.x Mh/s per GPU (Sapphire)
-------------------------------------------------------------------------------------------------------------------------
The weird thing about it is that it follows no pattern. The same Sapphire 7970 with two other 7970s in that system running generates 14 Mh/s more than if I add the Powercolor card into the system. But, if I put it in a system with only one other card running it generates -3Mh/s. It is something whacky with Windows and 7 series GPUs.
The first rigs I ever put together were 4x5870 rigs with xubuntu 11.04. Each GPU ran at 980e / 170m and generated 433 Mh/s. I recently had to split some of my rigs due to not having enough risers. Using the same 11.04 cd, catalyst 11.6, and SDK 2.5, two 5870 at the exact same settings till got 433 Mh/s. If that were Windows they'd somehow magically be getting 450 ish Mh/s.
I'd use linux for all of my rigs, but I need to have the ability to undervolt my 7970s to keep them cool as I live in a nuclear inferno. The only thing I can think of is that it has to have something to do with either MSI Afterburner, bios, or Windows power saving feature. At this point I've tried powered risers, moving power supplies aroun, testing voltage input from the wall, different catalyst versions, etc... I wish someone could figure this out as it is extremely annoying.
power saving mode? didnt even consider that <palmface/> |

Congrats on your success, I have traded allot with GLD in the past and everything went smoothly.
A couple of observations:
Move the chat tab to the right of the logout link, having it float on the right side especially on small devices really gets in the way of everything and is quite annoying. If I want to chat I can enable it from a stationary point and then let it float or dock to the right if I want.
In the /users/balances controller allow the user to move and or close securities of their choosing.
For instance, I traded GLD/BTC so I had no need to see BTB, BQC, CNC etc and got in the way of what I wanted to accomplish.
The left side bar is nice but detracts from the current experience, especially in the /markets/view controller, consider hiding it in this part of the site.
Just my .0000002 BTC

BCB & JohnK. are highly trusted here, I guarantee it!
I cannot personally verify this, but have been around long enough to confirm that other people have said that escrow with either of them went well. Good luck with your trade |

Scam Alert!, newbs watch out for this, 6 posts and the guy wants to sell 60 bitcoins.
Show us proof
How can he scam you if your meeting him face to face? Just make sure you meet in a public area and you should be fine. If he shows up with 12 friends with baseball bats..., just trying to help the newbs out, I don't want anybody to get scammed or worse, and we are not talking about 6BTC here for $780.00 we are talking about 60 BTC for $7800.00 which in my book is a nice chunk of change. |

I have USA checking account to send to. I'm surprised there isn't a tutorial for this after the dwolla fail.
I would suggest sending your BTC to coinbase, you will have to link your bank account but they are US based and VC funded (personally makes me less nervous). I have used them for 1 transaction, went very smooth with no problems. I even sent the BTC after 3 days to myself with 0 transaction fee. They use MtGox last price fyi. |

will you guys accept paypal payment? for those of us who are BTC poor  We want to promote Bitcoin. And since this is a Bitcoin mining machine, it makes perfect sense to sell it for BTC only. Initially it will be for BTC only, however, we might start accepting PayPal/CC later on. This statement is ass-backwards, if you want more people to get into mining with a decent hash-rate and spout the virtues of such to everyone they come across you would let them pay with anything they want to throw at you. That would be like Amazon forcing me to buy from them with Amazon coins. Do you not like USD or something? From what I understand the beef stems from the fact, if genuine, they have to play their rather unique suppliers in Bitcoins so would rather stay in that currency and it may help with tax related issues based on the tomato similie. Fact is guys, peeps are happy paying a little extra and covering the transaction fees for the case of security. See, some words haven't been as strong as their promises suggested they would so far... This makes sense, I hadn't considered this line of reasoning, thanks. |

Anybody have any ideas on this?
How do you guys get 3,4,5 or even 6 GPU's running without this issue?
