It was either Arctic Silver 5 or it was an OEM brand. Those are the only types I've worked with.
I don't remember exactly which it was.

With the $1800 at your disposal, it's probably best to splurge it all on good GPU's then.
Then make a dedicated mining machine with those good GPU's like grue suggested.
That will get you the most bang/buck as far as mining is concerned.

ok, so where in these forums can i find some discussion about the different mining pools out there I would like to make a decision on joining one. Or perhaps we can discuss some options here. It seems like deepbit is a popular option.
If you look through the mining board, each of the major mining pools has a post. deepbit has fees, though it's the most popular due to ease of use probably. bitcoinwatch.com has a little pie chart that lists the most popular pools. When I'm not solo mining, I'm using btcguild myself right now, and deepbit is my backup pool. |

Why would multiple cheaper rigs be better? The issue is the insurance, I have to give an equivalent build, I can't tell them two computers haha.
that does look pretty cheap, and I can do up to 3 cards in xfire, correct? Yeah I heard antec's ps was better, thanks
Ah, well my idea was multiple computers, more GPU's, but if you can only do one rig... How does this insurance work? You don't get to keep the full $1800? From what I've read that MSI board should handle quad crossfire at x8 speeds. |

If you're mining with AMD cards you should have the Stream SDK installed already.
2.4 is the latest version, that and version 2.1 are the best for mining, so I've heard.
With MSI Afterburner, you could probably push those cards enough to get 110-120 Mh/s each out of them.
If you join a decent pool, you'll make about 3/4 of a BTC per day probably.
I don't do those calculations with any precision though.
The other guy's on this board have excel spreadsheets, etc... etc...
I'm a rounding guy myself.
I do it in my head and guess the rest.
Uhh no...? He is about 200mh/s right now. That would only earn him 0.42BTC per day using deepbit's calculator. I'm at 2gh/s and I get 4.5 a day, there's no way he could get 3/4. Deepbit's calculator, eh? Well I prefer feeless pools myself. Like I said though, I didn't calculate crap. I guesstimated those numbers in my head. Forgive me for being a little off. ;p |

But yeah, a 5670 gets about 80 Mh/s and the 6670 is supposed to be the 5670's big brother, so if you're getting over 100 Mh/s you're doing quite well with that card.
uh, no. due to AMD/ATI's messed up naming scheme. the 6xxx cards have their second digit increased by 1. so a 6870 is comparable to a 5770, NOT a 5870 That's just the higher end Barts cards. The 6670 is an improved 5670 in essence. 5670 stats: Core Config: 400:20:8 Core Clock: 775 Mhz Bandwidth: 64 Gb/s GFlops: 620 TDP: 64w 6670 stats: Core config: 480:24:8 Core Clock: 800 Mhz Bandwidth: 64 Gb/s Gflops: 768 TDP: 66w See? It's pretty much the 5670's big brother. |

You can save a lot of money if you go the AMD route and do an MSI 890FXA-GD70 motherboard.
Also, you can get the Antec 1200w PSU Quattro for $200
Versus what you have selected, if you're doing this for mining, it would be the smarter option.
You could probably save enough money to build 2-4 rigs total.
Which would kick the crap out of the single rig you're thinking of getting in terms of hashing power.

Ah, sorry about that, I'm not too good at explaining those sorts of things on the first try.
But yeah, a 5670 gets about 80 Mh/s and the 6670 is supposed to be the 5670's big brother, so if you're getting over 100 Mh/s you're doing quite well with that card.
I don't know how well a 6670 overclocks, but if it's anything like my card, then you can squeeze some more performance out of it via MSI Afterburner, if you use the unlocked mode.
However, it does come with a risk, and ultimately lowers the life span of your GPU.
If you don't want to try it out, I understand completely.
Best of luck mining, with the setup you have, you'd be best off in a pool IMO.

$50-100 to spare?
Get a 5830, they're only about $100 now.
If you overclock a 5830 properly, you can easily pull 275Mh/s +

That looks short though, what if I want the card 1 ft away from eachother (to keep heat levels @ a min)? There isn't any reason you can't chain them together. Secondly, there's other external PCI-E cables online if you look around, some companies will even make them a custom length for you. |

Yeah exactly my point. You say I should get at least around 80 Mh/s when I am only getting 100,000kh/s. A 10-20% increase means nothing in solving my issue. It is more of something I would think about doing later on. For now I'd like to at least get speeds fast enough to generate some BTC within the next couple of months lol.
80 Mh/s = 80,000 Kh/s If you're getting 100,000 Kh/s then you're getting 100 Mh/s I take it you're not that good with metric conversions? |

No need for another case,, stick all 4 cards in there....850W PS more than enough..
Only if your mobo has enough slots and are far apart, or else how would you stick 4 cards if their next do eachother? PCI-E riser connectors |

I'd bet money on you being 100% fine at stock speeds.
If you overclock too far though, you might get a hard lockup.
Overclocking can increase power draws significantly.

Not 10x the speeds.
100,000 Kh/s = 100 Mh/s
So you'd be getting 10-20% more.
If you don't want to overclock that's cool.
I personally am overclocking my 5830's.
Put me from about 220 Mh/s at stock speeds, all the way up to 285 Mh/s
The stock speed was 800 Mhz
I overclocked them to 975 Mhz
I didn't even play with voltages, not that you even can with 5830's

If you're using poclbm on Windows 7 with those series ATI cards...
-v -w 128
Try those flags out if you're not using them already.
Afterburner can let you overclock further than AMD overdrive will.
Are you using AMD Stream SDK 2.4?

You should be getting about 80Mh/s each for 6670's, that seems like the right numbers to me.
You could try adjusting the settings in your miner or overclocking with MSI Afterburner to increase your speeds.
What OS and which miner do you use?
|
|
|
|

It doesn't have any OpenCL support, so no, you can't mine with it using existing miners.
There may be a miner made specifically for older cards that might work?
If not, you'd have to reinvent the wheel yourself on that one.

My mining rigs have kicked the breaker in my house once, but beyond that I don't have any scary mining stories.
Hardware stories though?
Once I was replacing the thermal paste on my CPU, I got some thermal paste on my hand and didn't wash it off. (That's a BIG mistake depending on what type of thermal paste...)
I now have a permanent chemical burn on my hand from CPU thermal paste...
Any skin I have that grows over the burn dies at a very accelerated rate, it looks like psoriasis.
did you go to the doctor for that? Nah, I didn't go to a doctor, I went over the affected area with a razor blade as soon as I realized it was burning, to get out the skin and chemicals. I washed off what I could, and I tried to cut the chemicals out of my skin, but I didn't get all of it. I don't have prints there anymore. It's on the right side of my right hand's index finger. |
