Guys, someone of you have this board? Can you tell me how speedy this board can crunch the WU? I'm taking around 88 secs per WU on MW on a 5870 w/ 900MHz o/c. Thanks! |

I have a Sapphire Radeon 6970. No oc. Perhaps a bit faster. Saw some being done in 80 sec as I write this post. |

My 5970 (which is two 5870 gpu at 5850 speeds) overclocked to 923MHz gpu / 901MHz memory does a typical wu in 83 seconds (depending what is crunching on the CPU). Without anything on the CPU it would do them in 79 seconds/gpu. |

TGG What did your HD5970 do at stock (725/1000)? Mine is concentrating on DNETC Go away, I was asleep ![]() ![]() |

TGG John: No idea! But based purely on oc versus stock ratio (923/725 = 1.27) it would be 100 to 105 seconds per typical wu depending on what the cpu was doing. cncguru: Everything I see is tinged green for some reason! |

My 4 6970's are crunching the 213.76 wu's in 65-66 secs. Hey... they are all running stock speed? Thanks! Can you describe more precise your rig? CPU type/Speed, MOBO, PSU(s), RAM ? |

Core i7-950 @3.07 10GB corsair DDR3-1600 8-8-8-24 Corsair H50 CPU watercooler(moved to better H70 lately) Asus P6T7 WS Supercomputer motherboard Silverstone ST1500 power supply (4) XFX HD6970 @ 950 core 900 memory and +20 powertune Intel x-25m 80GB SSD LG Blu-ray/multi burner/player w/lightscribe I got almost the exact speed when I ran my very first 6970(it's posted in another thread awhile back)@ stock 880 but as I added more cards to the motherboard it required raising the clocks and then also powertune to keep the crunching time @ 65-66 secs/wu. This guy is the most stable running of all my systems. I have yet to see the first BSOD since installing the (4) 6970's!! I did have to strip out my Raid0 15K RPM SAS array tho! Takes alot of power to keep these babies maxed out! |

Core i7-950 @3.07 Impressive Setup, your PSU is 1.500 Watts? WOW! LOL!!! I got my XFX also 5870, but I needed to lower the memory from 1200 to 900 Mhz, otherwise the Screen flicks and my PC got BSOD, but, the GPU, the most important is runing at 900 MHz @ 62 C. temp. I'm running in a Intel Q9550 2.83GHz @ 4.00 GHz with 8GB Patriot RAM ( 2.00B ) Gigabyte Mobo, Crucial C300 64GB SSD Sata 3. Does your PSU have support for all this video card? Regards! |

Yes it comes with all 4 lines that split off into 8pin/6pin each and it is 100% Modular. Another power supply I can vouch for is the Antec 1200 which also comes with complete quadfire power support (I have two of them each running 4 gpu systems with no problems ever) but they are 5870's |

Gigabyte 6970 w/o oc - 68 seconds per task (85 fore some longer tasks). Anyone knows how long it takes for nvidia 580? |
