Hi and welcome :).

When you follow this guide you will be mining in no time!

I doubt there are many (any) air cooling solutions that can cool 2x7970s running at 750khs in a case with the side on. The main issue is that the cards are simply too close to each other and the hot air from back of of 1 card get sucked into the fans of the other and it over heats.

Been there, tried it (in a HAF-X with water cooled CPU) and failed. Simple rule, if you want to mine with more than 1 7970 pushed to the max (~750khs) then you need the side off and a desk fan blowing in. If you want 3cards plus you need to look at custom open air setups.

You might get away with running it for a few hours, maybe days if your lucky but you WILL kill the card. Also just cos the core says 80c, doesn’t mean your VRMs aren’t frying themselves.

Mining is NOT the same as gaming. Just cos you can game with 2 cards doesn’t mean you can mine with them.

hello i just noticed this post so i have not tried it i tried seeing the ictures but i can only see the 1st and 2nd picture the 3rd link wont pop up

I can only advise you how I’ve done it. I don’t know if this will work for you. btw I’m using a stratum server like d2’s

[b]PROXY[/b]

I’m using guiminer-scrypt for my stratum proxy. Just realized im even using an older version too… but 0.04 should be fine i presume.

Go file - new miner - new stratum proxy.

Chuck in your proxy details and see if the proxy starts correctly.

[b]CUDA Miner[/b]

Inside your cuda miner directory, you want to make a .bat file with this typed in it. Where ***** is your username and ##### is your password

[quote]cudaminer.exe --no-longpoll -O *****:##### -x localhost:8332[/quote]

Start your proxy, then run the .bat file. fingers crossed it will connect and start accepting shares. I’ve included some screen shots that will hopefully give you an idea of what to do and what things look like if there working.

Let me know if you need to know any specifics. And also forgive me if this doesn’t work.

yea i bit the bullet and ordered the parts last night. This will put me at 3 rigs total plus a 5850 (unless i shove it into on of the 3). i have the power with 1500 watt power supplies. Thanks for the support and I think at worst i will break even.

So, what are your hashrates with 270 and 290 guys?
[/quote]

Getting 420-440KH/s on my 270x
[/quote]

290x with a completely untweaked config is getting ~800K

Are you using “auto-gpu”? This flag actually will try to lower your clock speed to help with cooling.

in cgminer? ADL doesn’t work so fan, gpu funcs don’t work.

the 8000 series is an OEM only series and will be seen in a few laptops and thats it. The 9000 series got a new name and its the R7 and R9 series of cards. All are rebranded version s of the 7000s except the R9 290/290x with new firmware/bios.
[/quote]

I see, thanks for the information!

[quote name=“RIPPEDDRAGON” post=“36645” timestamp=“1385503158”]
They sent you a 280x for a 7950?!? NICE!!! You should return more and upgrade your hash rate imo! I am looking at getting much bigger here soon so let me know if you want to sell some for BTC
[/quote]

Yeah i have 3 more 7950 about to fail in the same way…
So i was wondering about sending em a mail and tell em that since you replaced to one… i have three more about to fail… Still don’t wanna refund me?=P
(keep in mind that the time before i got full refund for my 7950, which was the same value as the 280x is now…, so either way i will be good).

Don’t like that i got a new sapphire however, those fan constructions are just to bad imo… want a gigabyte card instead…

the stability of the block rate is what I was concerned about.

since the FTC price bubble the hash rates went from 2.7 Mh/s to over 6.5Mh/s and the difficulty will adjust up highly

like you said, the profitability pools will see that FTC price has come down and difficulty has risen and they jump ship, leaving the block generation at 3.5-4.5 minutes per block. I watched it happen a few times over the last few days.

Well I don’t need USD as I’m in the UK but I would be happy to trade with you. Where u are how expensive are block erupted ASIC bitcoin miners. The price here is getting to £35 or more if you could buy them and post then for about £20/£25 I would be very interested in buying them and paying in feathercoin.

no i ment AMD MSI 7790 :)

Thanks for the reply :)
The problem solved itself… somehow. Anyway, it’s working now! 250 kh/s *it’s something*

ok update so i got the AMD MSI 7790 card out only problem is on Guiminer it shows where you can click on model you have and it will set values in on its own. I do not see anything for 7790 in the box i see from the 5500s — 7900s. I need to know what to do please remeber i am noob so dont want to mess around with setting this or entering comands here. My luck i would somehow explode my pc lol, no joke :'(

You mention OSX so I assume you have an nvidia card and may want to check out cudaminer.

[/quote]

If that is the case, install the cuda toolkit from the Nvidia website and use cudaminer.

cudaminer gives at least 5 times better hash rates compared with cgminer or bfgminer on nvidia cards.

When I started mining, I used an nvidia 8400 with linux at 2 khash/sec using bfgminer.
It increased to 12-13 khash/sec using cudaminer

Just checked my power bill… 29.403 cents per kWh (this includes GST/tax)

Converted to USD at time of writing, it’s roughly 27 cents per kWh

Or 0.2 Euro’s

Suppose I can’t complain to much.
