GTX295 installation problem
 
So,

I'm trying to install the GTX295 into the following rig:

ASUS F1A75-M Pro
A6 3670K
SPI 650W powersupply.

I only want to put in there for folding purposes.

However, when I install it, the rig does not post. Instead it gives me the (one long, three short) video card warning signal. I checked the GTX295 in my other rig, and it starts up just fine. I then installed a GTX680 in the APU rig, and that booted up just fine. So, it seems like the problem is between the 295 and the F1A75 motherboard.

Any ideas? And before anybody pinpoints the powersupply, that powersupply ran the GTX295, an HD7950 and an overclocked Hex core thuban processor concurrently in my previous rig. So, it's not the powersupply.

Not that it will be the case, but the only issue I could possibly see is the PCI-e slot not giving the 295 enough Juice, where as whatever other comp you put it into has no issues. The 680 being a much more recent efficent card doesn't have the same PCI-e consumption and therefore works.

A long shot, but its really the only thing I can think of.

Hmm, I wonder how I could prove or disprove this, and if so, what the remedy would be.

I thought PCI-E slots were supposed to give a solid 75W of power...

Like I said, long shot but its the only thing comming to mind.

I think the newer style cards (6XX series) pull from PCI-e cables first and slot second. I could be totally wrong though.
The only possible way I could think of testing GBA is find another card similar in power and vintage to a 295 and put it in.

GX2 maybe, 3870x2 I dunno, something that will eat a ton of power.

Just a thought.

Hmmm, Okay, so no reasonable way for me to test this theory then.

Anybody else have any ideas? I just really want to get this card in and crunching away. I could always put it in my main rig, but I don't want to potentially disturb my 680 from crunching 170K PPD.

Sorry :(

Was only a theory, and the only one I can think of, unless there is some BIOS item that needs to be enabled, but that is doubtful.

Hey ST, it's not your fault I'm having this problem. You actually gave me an idea that I can potentially test around.

Okay I think I know what your issue is. I had this before loading a Nvidia card into the FM1 setup.
Go into the bios under video settings set main video controller to the PCI GPU and disable on the onboard. you might have to take screen shots for me to walk you through if that's not it as I dont have any of my test benches in Calgary yet. but oh also make sure the newest bios is on, I have not had enough time to read your full issue as I am at work :)

I already tested a discrete GTX680 on the board, and it worked. So, are we sure this is the problem? I will try when I get home.

wait a second the 295 thats a sli on chip card right? is the lack of SLI support a issue? I could be completely off I will ask tech support in a moment :)
