I have bought 6 pci express 1x to 16x powered USB raisers. I plugged all in correctly, but when i hit start button, the computer does not power on, all it does is give a small push to the fans for a split second and nothing happens. the fans turn on for a split second then powers off. the computer does not even boot or start or show anything on the screen. it simply does not start at all. specification: Motherboard: Gigabyte GA-Z87X-UD3H Powesully: 3x xfx 850W GPU: 6x r9 290 Raisers: 6x http://www.ebay.com/itm/PCI-express-1x-to-16x-16x-1x-mining-Extender-Riser-Card-Power-USB3-0-cable-/271378879332?pt=LH_DefaultDomain_0&hash=item3f2f711364Raiser info: the raisers have jumper installed so i dont need to do a jumper on the pci e 1x for the motherboard to recognize the card. |

my 2x 6990 are running at gpu cock 970 and mem clock 870. i have no problem with heat and the cards are at 60-65 celsius.
i want to overclock to 1000,900 or 1100,1000. but using amdoverdrivectrl the cards gets unstable and stop working when on 1000,900. its not heat problem because i have no problem with heat.
to overclock past 1000Mhz core and 900Mhz memory, should i use windows 7 64?
im running ubuntu 64 and amdoverdrivectrl 64.
any suggestions?

i have downloaded amdoverdrivectrl (64 bit) and it dont work properly. it sets gpu mhz to 950 but when i set memory mhz to 150 it will only show but not work under load: Adapter 0 - AMD Radeon HD 6990 Core (MHz) Memory (MHz) Current Clocks : 950 1250 Current Peak : 950 150 Configurable Peak Range : [500-1200] [75-1500] GPU load : 99% i have the same problem: Even leaving AMDOverdriveCtrl running, same result.. the displayed ranges of --odgc make it look like lower clocks are possible, but below some threshold which varies based on CPU clock any change (from --odsc or GUI) doesn't take effect and in fact causes the memory to snap back to the default for the current load level. Arrrgh!!!
thanks |

hi
im new here and to bitcoin. i have read a lot about bitcoin for 2 weeks now and finally decided to start with mining bitcoin but i want to start small....
you might tell me to read more about bitcoin but i think i know enough but no one is all knowing hehe.
so i have 1600usd, many friends told me to buy bitcoin and sell later when they rise, but i want to mine my bitcoin and this is the money i have to invest on hardware for bitcoin mining.
im not noob with building computers and im not pro. i have built 6 or 7 computers for my self and friends so far, all from parts and components ordered from different places. and i also have good experience with overclocking (right now im on a intel 920 2.6ghz overclocked to 4.0ghz). and i have studied electronic and will study electronic engineering next year.
so finally my question hehe:)
i dont know which hardware to chose, i can chose a good MB and GPU and CPU and RAM, but i want advice from bitcoin miners. i want to know what mb and gpu and hardware you are using. i want to know your hardware.
thanks very much for the help, i appreciate it.
and sorry for my bad english, its not my first language.
cheers.
