I have noticed that there are 6 distinct programs in my windows un-install that all have Nvidia on them. One, of course, is the video card driver. On a Seti only computation box which other ones are necessary? It lists: 3D vision driver, 3D vision driver controller, GeForce Experience, HD Audio driver, PhYic systems software. Each one takes up ram and uses cpu/gpu cycles. Which can I do without? The same question applies to the Radeon side. Thanks, Tom A proud member of the OFA (Old Farts Association). |

 None are necessary for SETI@home You can search on Google what they are. I think: 3D vision - for 3D glasses and monitors GeForce Experience http://www.geforce.com/geforce-experience HD Audio driver - to send Audio to TV via HDMI PhysX - some games (Switchball) and demos (FluidMark) need it I don't think they consume any noticeable CPU/GPU/RAM while not in use (but you may check the list of processes to see in your case)   - ALF - "Find out what you don't do well ..... then don't do it!" :)  |

I did un-install everything on two of my lower end systems (didn't think it would matter at all on a Xeon). One system keeps re-installing the HD Audio drivers, the other doesn't. Hmmmm.... I also un-installed the equivalent stuff on my netbook. So apparently as long as you have the basic gpu device driver in place Seti will happily use your gpu. I can understand them not taking up cpu cycles. But they do take up some ram. And conventional wisdom for speeding up windows is "un-install" any programs you are not using...

One system keeps re-installing the HD Audio drivers Yes, Windows do that If you don't like this you may try to disable the device (HD Audio on the video card) in Device Manager So apparently as long as you have the basic gpu device driver in place Seti will happily use your gpu. I don't know what you consider as "basic gpu device driver" but: - on NVIDIA you need CUDA and OpenCL drivers - on ATI AMD you need OpenCL drivers (I don't know how it is on newer driver packages, in the past the ('custom', 'advanced') selection to install CUDA and/or OpenCL is separate from 'Video driver') Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

They do not take up RAM unless they have a component loaded at startup. I'm not sure who told you that to speed up Windows you have to uninstall anything you're not using, but that is bad advice. The only thing that affects Window's performance is background running applications which you can get rid of either by killing or preventing them from loading in the first place, and turning off services you don't use. |
