[QUOTE=Zerg_humper;16620184]So there's really no way to switch at startup? Cause that kinda of sucks. What about with a dual boot?
low power => Linux launches and the X800 XL starts up while the GTX 275 remains off
gaming => Windows launches and the GTX 275 launches while the X800 remains off
Might that work?

See my goal here is not just saving power, but also making my PC quieter and the fan on my 275
is like a jet compared to my X800[/QUOTE]
That would required a huge recompiling of your used linux distro.
just use the GTX 275 and underclock it when not gaming with rivatuner or some sort.
[QUOTE=nVidia;16620216]Just use the GTX 275 all the time.[/QUOTE]
Wow thanks for that insightful and helpful response.
Ok here we go again
GTX 275 even in low power mode is 2x louder
and uses 40 more watts than the X800
I want to be able to switch between the cards, even if it means a dual boot
configuration, I just don't want to have to physically swap cards everytime.

See I don't care about how much work it will take in the short term, I
just want to know if it would work or would my second card still spin up when the
system starts?
[QUOTE=Zerg_humper;16620122]Because for one thing the card runs really hot and I have
to run the fan at 80% power to keep it cool, whereas the X800 is quite and uses less power.
[editline]02:03AM[/editline]
I have both cards in my PC right now, I'm not trying to run both at the same time, and my video cable is
hooked to my GTX 275 right now, but the 800 XL is powered too.[/QUOTE]
There is nothing wrong with leaving GPU fans high
They were designed to run that way
GPU's put themseleves into the CPU equivalent of idle mode, some cards even downclock the shaders
iirc the total usage for a 285 in idle 2D mode is only around 40-60 Watts

yes it would, thanks to mobo design.
The X800 is powerd by the PCI-E bus, so short answer, no.
It's impossible withouit recompiling your own BIOS.
no, no, no, no, no.
I figured out a workable solution.
Could a mod please close this thread? Thanks.
OK.
Here's how it works.
You can not disable specific PCI-E lanes from BIOS or software. It just doesn't work like that. Unless your motherboard is spiffy and somehow supports disabling certain PCI-E lanes, then it just wont happen.
Your X800 will use less power, correct. But you'd need to physically unplug your GTX 275, or make some sort of massive switching device that literally disconnects it from the PCI-E bus and the power supply.
Running ATI and nVidia drivers is asking for trouble IMO, you'd get better performance dumping the X800 and running just the 275. Underclock it, it will use less power. Sure, it wont be as low power as an X800, but you have a fucking i7, why the hell are you worried about 40 watts of usage??
So to make what you want work, you'd need a physical disconnect, or have a magic motherboard that can disable PCI-E lanes. Even then you'd need to restart your comp twice every time you want to change cards. It just isn't sensible to go to all that effort just to save 40 watts of power. If you wanted a low power rig then get a nettop and boot that up instead of this dual graphics card nonsense.
EDIT: Please tell us your workable solution? I'd actually be interested in what you have planned.

My bad, logged off after that last post.
Actually the solution is part of what you suggested, a friend of mine is selling a netbook so I'll just buy it and use it for basic stuff, although that leaves my X800 gathering dust, my PC noisy, and my electric bill [i]slightly[/i] higher.
On a completely absolutely unrelated note, anyone interested in buying an X800xl GPU? :smile:
Why buy a laptop?
Get rivatuner, downclock it the lowest you possibly can without the drivers failing and save it as a profile. Use that profile for basic desktop stuff and turn it back to normal for games.
In a very, very low clock it will use even less power than the X800.
Did you build your PC yourself? If so, there are plenty of good guides on getting decent airflow and reducing noise in a PC (like using 120mm low noise fans, rubber padding, cable management, etc).
And really, your electric bill would be no higher than if you had a 50 watt bulb running for the same amount of time.
Sell that GPU on eBay, suckers always pay more. >:)

I saw a 9500 with that written in the information.
I giggled.

Oh cmon! You don't deserve that computer! Its probably a prebuilt isnt it?
The way it sounds really isn't everything bro. I meen if i had a loud fan i would only change it out if i had a spare just laying around. But I don't care if it DOES sound like a jet, I would LOVE to have a computer that had a gtx275 in it.
But it really isn't possibly, And it really wont impact your power bill unless you keep it on constantly. Though it probably did seem like a good idea at the time.
Why do you even need to do this, just fucking take the x800 out, it's a piece of shit, underclock you're gtx 275, hell why do you even need low power mode?
[editline]11:27PM[/editline]
wait didn't read the cooling post.
[editline]11:29PM[/editline]
anyway, fucking hell a GPU isn't actually loud, jeez, my system with a gtx 295 (which recently, fried, I hate my fucking family, younger cousins are always fucking shit up) barely puts out any sound at all, hell the only problem with the system is the hdd, so I unplugged all the outer fans of it just to leave the CPU and GPU fans, it was fucking quite, Dude GPU's aren't loud!
