>>>*** ABOUT RivaTuner (suggested by Wang Chern Hoe): *** I'll keep that trick for my personal record and use, but we don't want to use any dual boot solution in the lab (at least not yet). For a whole lab solution I will agree with Cameron (cm...@ucsd.edu) who suggests to opt for a real hardware stereo card. But for personal purposes I find interesting to turn a Geforce 6800 into a Quadro and be able to run O, NOC and PyMol from the XP side, but I've read: - this will turn it into a Quadro 540 but not 4400 (COULD YOU CONFIRM THIS, WANG ?)
The Geforce 6800 has 12-pixel pipelines & 4 vertex pipelines. Now compare that with Geforce 6800GT or 6800Ultra which has 16-pixel pipes and 5-vertex pipelines. Now it is known that a Geforce 6800 card with an AGP interface can be soft-modded via Rivatuner to unmask all its 21-pipelines. You can also unlock its professional capabilities to provide you with stereo. As a further step, it will automatically determine a safe amount of overclocking for the GPU core and the graphics memory core. The end result is an improved performance. However if your Geforce 6800 comes with a PCI-E interface, then its GPU core (NV41) has only 12=pixel pipelines in silico, and hardware unmasking will not work, although it is still possible to unlock stereo and to overclock it. If I am not mistaken, the equivalent of Geforce 6800 is Quadro 1400, and the equivalent of Geforce 6600 is Quadro 540. In both cases, the performance is more than sufficient for crystallography. >>>>- as asked Sabuj (sabuj.pattana...@vanderbilt.edu) what is the magic taht modify the pin connector for the emitter. Wang could you tell us how physically the connection with the emitter is made ? The Geforce cards do not have a 3-pin mini-DIN stereo sync interface. So just buy a 60-GX-NSR from http://www.nuvision3d.com/the60gx.html to solve this problem >>>>[Doug Bailley; bail...@ncifcrf.gov] Our "standard" linux workstation is as follows. Dell Precision 370/380, Pent.4-3.6, 1GB RAM 120GB SATA, DVD+-RW, Quadro FX1400 NEC-Mitsubishi FP2141SB-BK 22" CRT NuVision 60GX Wireless stereo emitter and glasses RedHat Enterprise Linux WS. Our set-up is similar to the one above, except that we use Centos 4.1, which is the free equivalent of Redhat Enterprise Linux ES 4. Download your copy from http://www.centos.org. We also have a SGI Dial Box connected. It works under O on a Linux box after installing Joe Krahn's freeglut mod at http://spdbv.niehs.nih.gov/resources/ DISCLAIMER: This email is confidential and may be privileged.
