Yeah i have salamander ready to go on a usb stick, just need to find the time. Cards are all sapphire. It boots straight to windows when i put the bamt stick in. even when i disable the hdd it wont boot, its like theres nothing on the usb stick at all.
As the previous post said, forget BAMT and go with Ubuntu, there is a link I posted some posts back which contain all you need to set it up on a usb stick. |

Hi, Did you get to the bottom of this? I am having exact same problem, need Windows 8 maybe? Does it work? I have no experience at all with Linux and there are no easy step by step guides to follow  If you are using 6 of any 200 series cards you have to use linux. The beta drivers you have to use for R9 cards don't support more than 4, even in windows 8. It is a driver limitation, not hardware, as 6 work perfectly fine in linux. R9 cards won't mine on anything but the 13.11 beta drivers, it's not possible to use modified 79xx series drivers to get 6 working in windows (yet, give it time...) Five card r9 290x rig running in windows 8.1 is good just had to switch pci latency over That was posted a long time ago, and you still won't get 6 in wondows. I can run 3x Sapphire R9 290 Tri-x , 1x Sapphire 280x Toxic, and 1x 7950 in Windows 8.1 just fine, but in Windows 7 I get Code 43 on the 7950 (if I put another 280x in there I still get the Code 43) no matter what I do. 13.11 beta, 13.12 both work in Windows 8.1, but in Windows 7 I can only get 4 cards going. Fucking sucks. AMD needs to work this shit out. And of course, in Win 8.1 my GPU mapping is so screwed up I don't even want to waste my time trying to fix it. Hey I noticed that there is an issue running 7950/290 with 280X card in the same rig. The issue lies with the gpu threads setting. Basically both the 7950 and the 290 prefers 1 thread but the 280x prefers 2. Running 290 with 7950 works great, with just different settings on the intensity, shaders and everything else but running with a 280X in the same rig is not something that I would recommend. You can run multiple instances of cgminer on the same rig, but I dont really recommend that either... I would put the 290 and the 7950 in one rig, and sell the 280X or swap it with another 7950 or a 290 to get a more stable rig. Also, if you are not using riser cables that are shielded, that could also be an issue with EMI between the cards. You can buy aluminium tape to shield the cables and make sure the cables don't physically touch each other. Also, remember that the 290 is a quite new card so it requires later versions of drivers, that can also be an issue if you run on older set of drivers, as some other guide sometimes suggest. I.e you have to run this version, with this version of sdk etc. I think that is just bullshit. AMD releases new drivers for a reason, not to make the cards perform worse. I prefer using the newest drivers, since I have seen they provide the most stable configuration. I run both on Ubuntu and Windows 7 without any issues, but I have heard people having issues with more cards due to EMI or bad riser cables. I had a really strange issue with one rig, where two of the 290 cards worked fine but the third didnt, and it stopped after a while. I then switched to 1X->16X powered risers, and connected two of the cards to the 1X and one to the 16X and the problem dissappeared. Check my guide out in the previous post, if you fancy trying Ubuntu and want to run it on a USB stick instead of on a HDD and Windows. |

Added MNC/Mincoin, CSC/Casinocoin, SBC/Stablecoin (re-added now that it passed its 317k block for the re-target issue), and GME/Gamecoin
Good job! Any news on IFC? |

Great pool. Putting another 2400 khs your way.
By the way, had any time looking into IFC?

Hey what about IFC (Infinitecoin)?
Just joined the pool :-)
Reviewing IFC and will likely add it shortly  Thanks! No worries mate. Happy to help. Pool is looking good. |

Working on a more reliable block explorer right now, then 2.0 is next on the list! need more people telling me what they want in 2.0!
Great work, we appreciate it a lot! |

What is the current block reward for IFC ? Also does anyone have a site with a countdown to the next halving. Thanks in advance!
Current block reward is 16 384 and next halving is at block 518400. Right now we are at 515576. Not much left in other words. |

guys, remove your walls on @150
Yes, please remove your walls. It's too soon. no ones even getting to that point coz dumb twats keep jumping in...why cant they just think 'hmm if i go a bit higher ill get that price in an hour or so'. I wish cryptsy showed usernames so we could name and shame! :p You look down the sell list and tbh i think theres gotta be a lot in safe hands atm. I dunno what the total sells amount upto but its nowhere near the 9 billion in circulation! Someone sold 50btc worth at .000001. I bet he feels pretty awesome right now knowing he's already lost 25btc and pretty soon it will be a lot more. Agree. It is like throwing your money in the well. |

Thank you all for the answers.
What flavor of Linux do you recommend? What will work the best?
Would you recommend running it on USB?
Thanks once again!

Thanks man, but your links got censored. Could you post them again?

Hello everyone!
I've been thinking of building two rigs both of which will use 7990 for GPU mining.
I'm looking for advise on the following
* Linux/Windows?
- I am thinking of Linux since I am much more used with it and I wanted to run the OS from a thumb drive. Any thoughts? I also find it easier to administrate with just using SSH etc.
* MSI/Sapphire/Asus?
- Will it matter? What is better on win/linux?
* PSU? 1200W or will 1000W be enough?
- I'm thinking of 1000W, but unsure
* Alternating pools or just one pool, any tips on alternating pools such as multipool.us?
- Unsure if alternating pools are the way to go..
The rigs will be built without chassis and placed in a cold cellar. I dont think I will be using water cooling.
Thank you for all your help!
/O

Any good tips on alternating pools? I've been using multipool.us for a while but not sure if it is the right one to go with.

Hello all! Thank you all for leading me in the right direction, the PSU. I don't know how many hours I spent troubleshooting this, but now it seems to work! I did the following 1. Added another cable from the PSU to one of the cards, so each cable has two PCIe connectors, I added one cable and used one of the connectors on one of the cards. 2. I changed power outlet for the computer, just put it in another outlet. I used the same connector in the wall where I usually connect a BBQ, so I know that has plenty of power  I now do around 600khs per card, which is fairly ok. I will do some testing with underclocking etc now that it is working properly and no more 80khs. THANK YOU ALL! |

are you undervolting your cards at all ?
I had mine undervolted and one card was stable but the other wasn't. Had to find a value that worked for both.
I use two cards which have 2GPUs so I have 4GPUs but i only specify thread concurrency once ie --thread-concurrency 8192 not 8192,8192
Hello! No not undervolting at all. I did a test though. I disabled one of the cards in the device manager and just ran it by itself, it produced the expected khs. Then I disabled that card and enabled the other card and tested that one, same result. So both cards work. I think you are all right that this is related to the PSU. I only have a 650W bronze cpu at home, do you think it is worth the try? I also thought that maybe connecting more cables from the PSU as it is modular, so that each connection on the GPU gets a dedicated cable. Right now the connections are two cables from the PSU and then two connectors on the GPU's. But if I switch to four cables and one to each connector, perhaps that will make any difference. Thoughts? Thank you all for your kind help! |

Hey, I got the same thing when a set up my rig.
I tried to make a rig with 3 7950 with a 760 watts 80+gold psu. The 3rd card was like your one, only 80kh. I switched many times, but the thrid pci-e slot refuses to make more khs.
And when I used only two card, even on the 3rd pci-e slot, everything was right.
So it ends up to the conclusion : my psu wasn't enough to supply 3 card, even with a gold psu. I would say that your psu is kinda broken, since 850 w is clearly enough to run 2 cards. Is that a 80+ psu ? Remember that 80+ means 80% of power delivered, so 850*80% = 680 watts
Hi, This is the PSU I'm using: XFX ProSeries Black Edition 850W PSU ATX 12V V2.31, 80 Plus Gold, Modular, 6x 6+2pin PCIe, 10x SATA, 5x Molex, 1x FDD So I guess that could be the case |
