Topic: HD 6770 - page 3. (Read 6825 times)

You got a link for that? I can't seem to find 11.12 drivers.

http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx#1

That page shows me only v12.11 Beta drivers... Can't seem to find it anywhere else on the AMD site either...

EDIT ::

Note that at first the card was not working or even being detected by Win7... So I checked device manager -- it was showing the yellow exclamation mark for an unidentified graphics device. I then clicked "Update Driver" and it successfully downloaded and installed driver. Then it popped up as "HD RADEON 6770" as a new graphics device, and it says "Device is working properly" and shows "No conflicts". But GUIMiner still won't detect the card. Now I'm trying ATI's "auto-detect" driver installation tool to see if I have the latest/proper drivers. If that doesn't work either I'll have to manually find this v11.12 like you said...but I dunno where/how to find it.

Download the 11.12 drivers directly from ATI, as those were the newest drivers that included the 2.5 SDK. Install the drivers and the included SDK, and see what GUIminer says.

Well, no it isn't... The system detected it when I first booted it up and said it was installing drivers >> "Your device is now ready to use"...

But GUIMiner doesn't even detect the HD 6770... WTF... 

Nevermind, I got it... for some reason the card didn't come with ANY of the necessary cables. Luckily, I had the right adapter in my desk drawer. Card now working fine.

Thanks!  

I'm not trying to profit from this HD 6770. It's just for a live demo to show our shareholders how Bitcoin mining works, and prove to them that the Bitcoins produced can actually be converted to cold, hard cash.

Also, I view a GPU or any other mining equipment as part of the company's capital. The card can be re-sold to someone else to get back a portion of the initial investment (perhaps a bit more, because I can get em very cheap). So the card only needs to return a few bucks in a couple months time to be in the black. The important thing, however, is that my shareholders get to see the rig in person and see how it works... it would be hard to otherwise convince them I can spend a bunch of money on little computer chips and manufacture some strange new form of money called "Bitcoin" -- unless they see it for themselves.

@ crazyates ::

Oh yes, that calculator has already become my best friend. It was one of the first things that sold me on the idea of Bitcoin. ;-)

EDIT ::

Just installed the 6770 beneath my GTX-580 but the system doesn't detect its presence. The instructions didn't say anything about connecting a PCI-E power cable to the card, but it looks like it does indeed need one, correct (which explains why it ain't juicin up lol)?

Also, I haven't shopped for GPUs in a good while. Head-to-head, how does the 6770 compare to my 580? Is it a better card? Would I be better off running 2x 6770s in "Crossfire" mode (seems likely)?

Unless you want to upgrade your PC to play around and you have free electricity, I would suggest purchasing coins.
As for the GPUs playing nice together, try it and see. I know some that mix as you want to do with good results while others complain of constant issues. Personally, I have never tried it as I have several boxes with only 1 brand in each. Good luck with whatever you decide.

http://dev.bitcoinx.com/profit/ is your friend. Plug those numbers in (230Mh, 88watts, $80), and you can see your estimated earnings. It shows for me 0.03BTC/day, and would take over 3 years to break-even. I expect you will end up never breaking even, as that time frame does not take into account the 10x (minimum) increase in difficulty that will be as result of ASICs over the next 6 months. My 2 cents.

Thanks, I bought one to try it out. 230MH/sec @ 88W for < $80 didn't sound bad at all, considering that my GTX-580 is only doing 140MH/s @ 240W!... That's about 3MH/$ and 2.61MH/W, which is pretty cost-effective for a GPU... If I like this GPU I can get bulk pricing on them for much, much cheaper... would be able to assemble a nice farm and sell the cards when I'm done with my investor demo.  

Just to be sure: There will not be any conflict running my GTX-580 and this new HD-6770 on my Gigabyte mobo, right?

I'm looking at some HD 6770s starting @ $79.00 and below (depending on qty). IIRC, hashrate is > 200MH/s, but what is wattage?

I can get a bundle of these cards on the cheap-cheap, and they seem decent for the price... only concern is power consumption. But I can't find it online and I'm browsing on a piece of junk phone. Can anyone tell me the power consumption ASAP?
