One user have reported being able to run 4 GPU cards on a mobo using only a dual core AMD CPU.
I am in the process of building one, but one problem here.
It seems that Vista needs each Video card to have a monitor attached to it. Of course, I wouldn't have that many monitors.
There is this thing called a "VGA dummy". Now, most video card these days only have DVI ports, and I was wondering if there is such thing as a "DVI dummy"?
A DVI dummy termination is, at least in principle, possible. It depends on how the Graphic card recognizes a DVI termination. If the graphic card with only a DVI ouptput needs to see a digital feedback signal, then resistive load termination will probably not work. In other words the DVI output may require an active digital return signal to be terminated.
I can take a look at the specifications of the DVI connector and try to determine what is actually the case (maybe I can let you know what I learn by tomorrow night).
I am asking if anyone here can make a VGA or DVI dummy, I am more than willing to pay for them, and I am sure other members would find it useful as well.
Chungenhung, I can make VGA dummy terminators for you or anyone on The Longevity Meme team, at potentially at no cost to you or the team members.
It looks like the local Radio Shack carries the VGA connectors (15 pin, D connector) but does not have the required 75 Ohm resistors. There is a Fry's Electronics store a few miles away that could have both, but it will be a few days before I can get to it to check it out.
Perhaps it would be good for you and others on the team to decide how many are needed, or thought to be needed in the near future, and maybe locate a mail order source for the components. I could order the desired number of components, then solder them together and mail them out to those on the team that needed them.
Of course none of the above is very quick and you would probably like a quicker solution.
In the near term, you might try a KVM switch. All ports (in the not connected position) should I believe, serve as dummy terminator for those ports. If I am correct, a two port KVM switch can terminate one port (without any monitor) a four port KVM switch could terminate 3 ports with no monitor.
