[PyMOL] RE: [ccp4bb]: SUMMARY - nVidia Quadro FX 1400, FX 3400 and FX 4400

[Wang C. H. <che...@im...>]

>>>*** ABOUT RivaTuner (suggested by Wang Chern Hoe): ***
I'll keep that trick for my personal record and use, but we don't want =20
to use any dual boot solution in the lab (at least not yet). For a =20
whole lab solution I will agree with  Cameron (cm...@uc...) who =20
suggests to opt for a real hardware stereo card.
But for personal purposes I find interesting to turn a Geforce 6800 =20
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 =20
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=3Dpixel 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 (sab...@va...) what is the magic =
=20
taht modify the pin connector for the emitter.
Wang could you tell us how physically the connection with the emitter =20
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

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 =
