Glad to hear you are retooling back up nitteo!! Sorry about the EUE, what is up with so many of these lately?

Memory and core speed do have a small effect on your folding performance. There is no reason to not bring them up if you can.

Also, you will need to run the core at 1/2 the speed of your shader. The 54Mhz strapping will do this automatically for you, but keep that in mind when you are OCing. So as an example, if you are running at 1566 shader, the core will have to be at 783. That is what one of my GTX 260s is at, not sure what the 8800GT is capable of.

The shader strapping means that your GPU core and shader are only capable of running at certain frequencies. These frequencies are available every 54Mhz. Rivatuner may show you a core frequency of 774Mhz, but in reality it is running at 783 because that is where the strapping falls for the case of my GTX 260. There is a recent post here that does a good job of explaining it in the Folding Forum.

That isn't neccesarily true though, since Rivatuner allows you to unlink the core and shader clocks?

3. Depending on #2, could I get a link to the proper client needed?
4. Does SMP still run a DOS window minimized or is it like the old client where its just an icon in your system tray?

Thanks

EDIT: Is a dummy plug just used to "trick" your system into thinking there's a monitor attached to the second port? If so, why do you need to do that to allow F@H to use both cores?
As a senior moderator you should know about the search button and reading stickies; j/p!
Since the others have been adequately answered, I will only be responding to #4: If you decide to fold on both your GPU and CPU (and why shouldn't you?), you can use "TrayIt!" to automatically minimize the console client to the system tray. But in general I would advise to set up a Virtual Machine and run a Linux based SMP instance for moar PPD. Read through this thread for information about how to set this up.

No, it will still go to the 1:2 ratio of Core:Shader.

actually, i haven't had that problem. i've only OC'd shaders and my core doesn't move a bit.

Go to the hardware monitoring in Rivatuner and it will show you what the actual speeds of your core and shader are. GPUz does not show the actual speed of the core and shader.

It may not always require a 1:2 ratio of core and shader, but as far as I have witnessed and seen from other people, that will provide the best and most stable folding performance.

thats what i'm talking about. i don't use GPU-z to look at my clocks. i use rivatuner. i have never seen my core clocks go up if i go beyond that 1:2 ratio.

a good example would be my GTX... i'm running it at 1998 for shaders.. there is no way my core is going to hit 1000.

If you adjust them beyond the 1:2 ratio it will automatically push them back to 1:2. If you have it at a stable clock now, try adjusting the core up by a few clicks and you will watch it pop back down to the previous setting as you hit the OK button and minimize Rivatuner.

*EDIT* You can see here that Rivatuner shows clocks for GPU 1 that are not in the 1:2 ratio. 774:1559. However, in the Hardware Monitor, you can see how GPU 1 is actually running at a 1:2 ratio while maintaining the proper strapping. 783:1566. Also, the memory is shown as 1303, but it is really 1296 but I have removed that from Hardware Monitor.
