Can't help you as far as getting connectors, but once you get them can you keep the thread updates as to how well they work?  The reason I am curious is because I saw a thread before about those adapters and people were having troubles getting more than 1 to work.  It would be nice to see if you can get em' to work. 

How on earth are you getting 420khps out of 6870's without overclocking???

I would recommend a giant fan, like the one pictured above.  They are pretty cheap, and it should do the trick.

Does this mean that the motherboard you have can only take 5 GPUs on Windows 7, or Windows 7 can only take 5 GPUs?

VisionTek 6950 $320 together, or $160 each (plus shipping) - These GPUs both mine at speeds up to 450khps.  They are at the stock 1408 shaders.  These cards do not feature a dual bios, so I haven't tried to flash unlocked shaders onto either of them.  They are 2 slot cards, but they have a massive heatsink so they take up 3 slots of space.  These are the 1GB edition cards which might seem a little small but they still could handle games with up to 4xMSAA without VRAM becoming a problem.  Finally, as for temperatures these cards are great.  Under full load the cards only reach 58 degrees Celsius with ambient temperatures of 75 degrees F and a fan speeds of ~55%.

One of my 7970's gets 655khps at 1000MHz core clock, 1500MHz memory clock, and 1.163 voltage (won't let me go any lower).  However, I have gotten this card to reach past 1.2MHz on the core at its maximum voltage of 1.256v.  The thing is, the Litecoin mining doesn't scale up as I would hope. I can never get past 660khps no matter what I do.  I would like to break 700khps, as I think this card is capable of it.  At this point though, I think I need some guidance as to what I am doing incorrectly

I'll put 10 bucks down 

Anyone else with me?

You have to wait until the block gets 120 confirms (about 2 hours) until you actually get a payment.

Would you be willing to use escrow?

In light of this, I would be willing to buy any CHN you would like to get off your hands  .

Make sure ULPS is turned off.

I would recommend the MSI Z77a-G45: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130645

It is pretty cheap and you can get 6 gpus on there, which will give you an extra slot to expand.

As far as how to set it up (for 6 gpus, if you are only going to be doing 5 you should still be able to understand how) you will need 3 x1 to x16 powered adapter cables and 2 x16 to x16 riser cables.  Refer to this image (credit to ssateneth) https://dl.dropboxusercontent.com/u/9768004/z77ag45.jpg

If you only do 5 gpus, you wont need to pay attention to the presence short.  If you decide to go for it, look at these pics: http://blog.zorinaq.com/images/pcie-short-schematic.png and http://blog.zorinaq.com/images/pcie-short-photo.jpg

You simply plug the adapters and riser in the slots and then put your cards in.  Then you should be good to go.

Yes you can do this.  4 cards is just the maximum for gaming, you can have as many as you want for compute purposes.  If you dedicate any amount of cards to a xfire setup you can use the rest for whatever you want, in this case mining.

If you have Far Cry 3 or a Far Cry 3 code, PM an offer.

I messaged him.  There should be no reason for him to say no, especially with escrow available.  If he declines that would be a major red flag.

Across two 7970's, I am using 2.8 gigs.

1,398,780k on one
1,405,892k on the other

Would you take a rate of 100CHN/10LTC?

I would like to purchase around 1000 CNC.  I can pay in FTC, LTC, or BTC; whichever is preferred.  Send a PM to negotiate price. 

I will only do a transaction if you send first, we have escrow, or we break it up into small increments and you pay first.

Pretty sure this guy is a phony.  I traded 50 CHN with him, but he hesitated when I worked my way up to bigger numbers and wanted him to send first. 

Probably should stay away until someone else confirms he is legit.
