作者誰找我
fermi似乎有日產至少4萬ppd的能力...
這一位名喚FahMan, 說他用七片工程版fermi...
OpenCL

Hi Folks!
Thanks for your interesting in my humble contribution in team EVGA.
Some of you wanted to know about my hardware so please check:
www.fahmanfolding.webs.com
As you can see on photos this single PC is able to produce more then 200kppd (around 250 with extreme overclocking).
Some additional explanations:
I was forced to use usb monitor as GPUs haven't any video output (this engineering samples of Fermi are Tesla like, but they have 1.5GB of memory each like GT300 will).
Because of the new MIMD architecture (they have 32 clusters of 16 shaders) i was not able to load them at 100% in any other way but to launch 1 F@H client per cluster and per card. Every client is GPU3 core Beta (Open MM library). I supose it is much more efficient then previous GPU2. In addition they need very little memory to run. Having 16GB of DDR3 and using Windows 7 Enterprise I've managed to run 200 instances of F@H GPU and 4 CPU (i7 processor HT off). The 7th card is not fully loaded. This could also be an issue with EVGA X58 mobo.
I use together two Silverstone Strider PSU's 1500W each that is probably too much but
now I experiment with overclocking (cards are factory unlocked). Max power consumption
I've noticed was 2400W.
The whole system is cooled by my own construction of liquid CO2 which is heavy an inconvenient and I have to supply a new cylinder every 5 days.
That's It. I wish everybody to improve your folding speed using GT300 soon!
Just keep folding...

不知道是不是真的用了 一台i7 + usb顯卡+ 7片fermi 達到平均日產24萬.
小弟覺得有幾個問題：
Q1.
http://fah-web.stanford.edu/cgi-bin...username=FahMan
從上面的連結看到他是用了大約250顆核心才達到的日產24萬
算起來一個核心日產不到1000
Q2.
一台機器的頂多有16個Machine ID，
但FahMan有大約250顆核心..
希望fermi 的效率(PPT/W)可以威到讓小弟把9800GX2直接除役..
