[QUOTE=Rodrigo;317332]Huh, interesting. How does one find out which numbers to input there?

Another issue: If you do run mfakto (or whatever) on both the iGP and the discrete GPU, is there any processing capability left over to run, say, videos or Windows Media Center?

Rodrigo[/QUOTE]

There should be, especially if you run one less instance of mfakto than is necessary to max the GPU.

That helps a lot, thanks!

Maybe it's time to start playing with mfakto and see how it works. :smile: Other than Brain's GPU Computing Guide, is there a "one-stop shopping" place to look for info on how to run it, or should I just consult the "Trial division with OpenCL" and "GPU Trial Factoring FAQ" threads?

Yes, but consider perhaps the "Trial division with OpenCL" thread. :smile: Or even better, the README that comes with mfakto.

Shoot, you read my post before I finished fixing it!! :blush:

Much appreciate the info. :tu:

OK, next question. Do people run mfakt_ on their graphics card 24/7, or do they let it rest every so often? Are there any concerns (or not really) about burning the card out, or shortening its lifespan?

Not anymore so than with Prime95. I let it run all the time.

They [U]WILL[/U] - for sure - generate a lot of heat! (and take a lot of money from your pocket in electricity costs, but this is secondary). If you can efficiently get rid of that heat, you are good. Keeping the GPU at some (approximate) constant temperature will NOT shorten its life time, assuming that temperature is not ridiculously high. Running gtx580 at 45 celsius or at 75 celsius would not make much difference in its life time, assuming the thermal strain is low (i.e. you always keep the temperature around that level). Repeatedly switching between 45 and 75 would be much worse (and shorten the life time of the card faster, due to thermal strain).

As Dub' said, my cards are continuously running too. Usually I need to switch from "aggressive" mode to "polite" mode when I play high definition videos or work in autocad/solid works, otherwise the screen is jumpy. And this for the main card only (the one connected to the monitors).

Thanks @LaurV and @Dubslow, this is good news. The machine is liquid-cooled, so we'll soon find out how effective that cooling system is.

I see in the UEFI menu, under "Advanced," that there is an option to enable the Integrated Video (default value is Disabled). If I flip this to Enable, would it ipso facto disable the add-on graphics card? I'm assuming that doing this would not disable it, but it can't hurt to ask...

No. I do not think that it will disable the add-on card. This is only an On/Off for the onboard GPU.

Fabulous! This is sounding better and better.

I'll print out the README in the morning and proceed from there.

Thanks for your help.

You do, of course, have to load drivers for the various GPUs, *if available.*
If they are all the same make, then this will probably not be an issue.

*I have no knowledge of Intel iGPUs.
