In windows they are all at the defaults, I wanted to get them all running before I tweak.
I am using 2 PSU, one is an antec earthwatts 750, the other is an ultra x 3 1000 watt. 1000 watt is for 2 X 5970 and the 750 runs the mobo, 1 X 5970 and 1 X 5870.
Using Linuxcoin everything is seen and runs fine. So I think its not a mobo or power issue.
uninstall CCC. you only need the drivers and SDK. |

What is this pool's policy on hopping? Hoppers are not welcome here. This policy is not yet added to the pool rules because my hopping-detection routine is not ready. When I'll be able to detect poolhoppers with low enough number of false positives, this policy may become forced. I know that some people call proportional method "flawed", but since there are lots of users that like this method, I have to protect them from evil ones. why not just post the verbiage anyway then when ready implement detection when ready. |

I have 4 cards on my MSI 890FXA-GD70. Using windows 7 32 bit.
5870 -->GPU 0
5970 -->GPU 1 and 2
5970 -->GPU 3 and 4
5970 -->GPU 5 and 6
I could mine with any 5 gpu, when I add the other 1 or 2 it will decrease the hash rate on the others. Is there a setting in the mobo bios that I should adjust?
Help me solve this problem and 2 bitcoins are yours for the taking!
What are the clock/memory settings and what PSU do you have these connected to? |

I'll go take a screeny in the other room on the mininer istelf, I assume that it's actually dropping the mem clock because when i drop it i loose 12° I have an MSI 6990 http://imageshack.us/f/12/unlednfw.png/As you can see here, i can put the mem clock Much lower, Or the core Much higher Maybe MSI doesn't have this restriction.... I'll have to hunt one down. Too bad I've sold 5 of them already without trying them... (to pay for 2 sapphire 6990s I kept for myself LOL)  Appreciate you posting this! I am more than certain that it's not my specific cards, Have you gone into MSIa and under the EULA and typed: [ATIADLHAL] EnableUnofficialOverclocking = 1 UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 AccessibilityCheckingPeriod = 0 Once you do this you can set whatever clocks you want on whatever card you want, NOTE: MISa becomes very "tweaky" after you've done this, (EG: drag mem to lowest, Hit apply, Close misa, Reopen it, And it can go lower) Yes, I surely do know how to use and setup/configure MSI AB for OC'ing. was one of the first things I learned when I started with bitcoins... still, if you look through forums regarding 6990s you will see that people are unable to underclock memmory outside the parameters I mentioned. I will hunt down an MSI board and see if it behaves differently. Will post back here, but it may really take a while... |

What's the purpose of the clipped grill, anyway?
I was trying to fit it into an 8 year old dell system and i had to clip the bottom off to make it fit into the case. ended up replacing all my 5830s with 5850s, so don't need this card anymore. |

How's the noise level compared to a 5970?
couldn't tell you... don't have a 5970. but i suspect it's lower. because youcan down-cklock memory on 5970, thus attaining lower temps whenre the fan can be set to lower setting. this particular ax6870x2 won't let you reduce memory by much, so it does run hotter and thus louder. i have to keep fan at 80% . However, 6990 is obviously louder than all of these... for me though, noise isn't an issue... all miners are locked in a computer room... so i don't hear them. |

Any experience with that merchant? yes, they are fine. ordered a bunch of 5850s from them a while back. got them OK, took some time. |

not a bad price, but with ncixus there will be a shipping charge... so, far this card is not on par with 6990 or 5970s on Mhashes alone, but on price that's a different story... |

When I first put it in it worked just fine. I was doing some stuff on my hard drive (moving some files) for a while, went to watch a movie in the other room while I was mining.
I came back about an hour later and I had artifacts all over. There's less of them when I underclock my vram to 275, but when I start mining there's more of them.
I have a very modest setup:
E8400 dual core CPU, one hard drive, four usb devices, one disk drive and the 5850 card, and one case fan.
Is my two-year-old 380W earthwatts PSU enough to handle it? According to online calculators I should be fine unless the capacitors on my PSU have aged. I'll test my card in another computer later just to make sure.
Is there anything else that can be causing it?
you mean your memory clock is at 275? try increasing to 300ish... or take your core clock / 3 add about 14 and use this for mem. clock speed |

Hey y'all (directed at miner coders, but anyone can answer) is there a way to either currently or in a future patch run miners in "stealth" mode? like in Windows have an option where, for instance, guiminer might have a mode after configuring it that it's hidden and only shows up in Task Manager (either as it's exe name, or even a configurable process name)?
same question for linux.. maybe able to set up and then run on startup in the background? Note I'm not very good in linux CLI, but given instructions I could follow them if this is already possible (like maybe a cron job or something)
you trying to hide your tracks when squatting other systems? |

how did you set the 6990 to 600 memory?
MISafter burner.... make sure you've "enabled unofficial overclocking" Hell i could drop it to 300 right now if i wanted, but it crashes when mining Hmmm... I'm very puzzled... there have been posts after posts about the limitation of underclocking 6990s i don't know how you're able to do this. Which 6990s do you have? maybe yours are some particular brand that allows this... basically i can set the values using MSI AB or whatever other program, but if you actually lookup the memory speed with say GPU-Z it won't run at the specified memory setting. On 6990s, for pretty much most people here, you can only set the memory clock by 125 less than the core clock. ex: 930/805, 940/815 etc... etc... If I try something like 930/600 with MSI, the core speed will be set at 930 but the memory clock will be at the default setting(1250 i think?) according to GPU-Z... So, i'm very curious whether you could verify what the actual memory speed is reported at when you down-clock it. |

are you all reading just the core temp? if you use something like everest/aida64 you can monitor the core temp, memory temp and shader temp. most of my cards are within 5C for the 3 temps but one of my 5850s is reading 75C core 72C mem and 95C shader, it seems fine and stable but i am a little concerned so im watching it closley
dunno in their cases, but you can use GPU-Z, it's one of the favorites out there... |

FYI running fans at 100% 24/7 will exponentially decrease the lifespan of the fan
Without a doubt. And they spin slower too, So your 100% will eventually be like a 60% .... Then how exactly am i mining at 1ghz with 650mem
Swapping to 982core and 1000mem and going to run CS:S video stress test at -f250
To test the theroy of 100+/-= no bugs
Too much heat. im expecting to crash and i dont want to deal with that crap. Flipping back to 962core 1150mem
it seems that dual-GPU cards have these limitations. 6990s have them, now this dual 6870 has it too. seems like any dual-gpu 6xxx series is limited to how low memory can be set to in comparison to the core clock speed. i thought you meant you had a dual-gpu 6870, but i see now that you have 2 cards actually. Uhhh buddy? I have a 6990 running at 930core 600mem, Your still wrong 982core and 1000mem showed no glitches and everything went OK, aside from Notably slower memclock loads, But the 5° drop is seemingly worth it in the mining senario how did you set the 6990 to 600 memory? |

Dual6870BE's(gaming rig) Very clusterfucked tight packed Both cards run @ 85° for the past three weeks mining, WHILE gaming, No issues
6990 Open case/20inch box fan= 87° running 1month no issues
5830 same case 78° 5months no issues
Dual 6870's overheat at 90° and auto shutdown, I wanna run them at dual 1ghz but i can only run them at dual 981mhz due to heat
Which 6870 are you running? are you able to underclock the memory to low setting? I have not attempted to drop the memory clock on these cards since i use the Often for gaming. I will go try to drop the mem and start mining Dropping the memory clock to 575 cause graphical errors, But no crash, Nor any Sign of crashing, just Blatent Card Display failure due to too slow of a mem clock im assuming Both cards are running and linked crossfired I am going to raise the memory clock to see if i can remove the "damages" since i feel that these "skews" are actaully Hurting my cards I've been experimenting with this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814131446and so far the memory clock speed can only be lowered by 100 less than clock speed. ex: 900/800, 930/830 ect... can't go less than by 100. tried flashing bios. seems some restriction is on the card and/or windows catalyst driver. damn thing detects that bios was flashed and keeps rebooting computer. have not tried under linux. read some posts that implied that under linux flashed bios are working... if so, it's probably windows driver limitation then. |

idk, I suggested the chip because I assumed gates are gates, no matter on which fpga they are. So I did some comparison. This wasn't meant as a critique or that you choose the wrong chip, just me trying to help  I've heard that the markups of fpgas are quite high, so I assumed it is possible that a cheaper chip is available which could be used with similar or superior capability. Xilinx is the market leader so I think it's save to assume that competitors try to offer cheaper products to get a higher market share. I didn't read it as critique, I was wondering if you had found something... i don't know much about fpga's so that's why I ask. I wouldn't know how to compare them... at least not yet. |
