I run 7870xt at 1100mhz (1.113v) and 750 mem for bitcoins ~505mh/s Happy medium undervolted and overclocked!
Scrypt runs poorly on these units 850mhz .981v stock mem ~410kh/s@ 20 I 16834 thread.
how are you getting 505mh/s out of it only clocked to 1100? all the ones I have Sapphires dont hit 500 till 1150mh/s No idea, but I suspect yours are throttling. VRM temps get WAY too high at stock voltages and 1175 is the max I can run my cards at any voltage before they throttle down. Watch MSI afterburner and the gpu goes form 60-99% back and forth when the vrm's get too hot (even with a good gpu temp of 70c). Try setting powertune to 20% etc etc. and 375w is barely enough for that gpu. These babies have been known to suck nearly 300w each when overclocked at stock voltage, think 7950 territory. That plus cpu, ram mobo and I bet your psu is about to catch fire.  PM me if there is any other way I can help, that way we keep this thread cleaner. |

Sorry if this has been asked but eta till machines are physically in hand?

It's poor from my location (near Toronto) mining for 24hrs with ~4200kh/s netted a whopping 1ltc. Either he's scamming or there is a major server problem. Switched over to another pool based out of NY and payouts are as expected now. YMMV.

Of course none of us have a crystal ball  How does this system reward you if we keep bouncing between coins not long enough to actually solve anything? Does it pick up where we left off? I'm just trying to understand your system, not here to give you a hard time. Well, typically coins become more profitable when their difficulty drops. It's usually not the result of market price fluctuation (although it can be, but the difficulty typically has a far larger effect). Don't forget, submitted shares do not 'build' toward anything. Each share is a random guess at the solution for the block. Once a new block is found on the network of a particular coin, all the work done on the previous block is null and void. So there is really no penalty for switching between coins. If the multiport goes from LTC to WDC, all it really means is instead of submitting random guesses for LTC you are now submitting them for WDC. A block should be found every X random guesses, on average. (X depends on difficulty) Thanks! |

I have a sincere question, sorry if it has been asked before. But with this switching port (which I think is a great idea) it mines only what is worth the most at that point in time correct? What's the point if the coins are all up and down in value? Why not just mine what will be predicted to be worth the most over the time it would take to get a block mined so those of that are into quick sales can do that? Sorry again if this has all be covered!

I'm mining away just fine, if it keeps working I will stay  Coinotron keeps annoying me with insane page load times and site outages. |

I have bought some new cards, got some free hats and crap and already have all these games. Help subsidise my card purchases 3x Bioshock Infinite 3x Crysis 3 2x Blood Dragon 1.2btc You send coins I send the keys, yes you'll need to trust me. I'd rather send this out as a lot to one individual. Only 2x blood dragon as I gave one away to a friend as a gift. Offers will be considered. https://www.bitmit.net/en/item/36854-lot-of-11-game-keys for the gun shy folks. |

One set of ram I had would refuse to run at all with any manual/default auto settings (probably a bios bug) but I found that if I forced the xmp profile it would work fine. This was with some "fancy" Ripjaws ram and a gigabyte 990fx board.

Thanks for your "pro tip", just the tip right?
I find that strange as we should be looking for every scrap of extra performance we can get. Perhaps for the people with larger farms this makes little difference due to the downtime involved but I don't mind experimenting, part of the fun for me with a hobby that pays.

Where is the "Caution don't do this shit" area then  PS- I'm using 7950's so....? PPS-These did work fine with the non-beta drivers using no monitor connections, dummy plugs or otherwise, this was an attempt to be helpful. |

Sounds like bad ram or psu. Try memtest86.

Can't seem to run my machines headless with the above drivers, two different machines and the same results with various settings in afterburner. All are using a combo of 7950's (gigabyte, sapphire and xfx). I'm using TeamViewer as my means to connect to the machines... With no monitor connection can't get any video to display that isn't all blocky and distorted. This is not a cry for help, just a warning for anyone wanting to try. I guess I'll have to get some dummy plugs at some point and give that a try. |

Same link won't work for me either  |

850 core, 1500 mem, .981v
Reaper 16384 threads, 1, 1, worksize 256, intensity 18 ~400kh/s
I have 2 Tahiti myst cards in one machine and they both work fine with these settings.

That's a shame |

If it was just the amd driver failure then YES! I've found with my setup that if I enable and then disable crossfire it resets the driver if that is all that has crashed after playing with o/c settings.
