Hi I have been looking throught the forum and found a few people that have had issues with bios recognising the graphics card I have this sameproblem with a Gigabyte GA650 sli rev 1 MB vs a Leadtek gtx660 2gb graphics card .The MB does not recognise the card at all when set up as single card to enable the PCIex16 slot and will only see the card when set up SLi in slot 2 at PCIe 8X it intermittently doesn't see when set up like this either. Do you feel that a bios update would help solve this issue or do I have a major problem with the MB or the GTX660.
Yours hopefully... Paul.

given it runs in the second slot under sli, chances are its a switch that needs to manually set on the mobo, so that it's not in sli config, and then the card should be picked up in the first slot. Alternatively there could be an option in the bios for something similar. I know, on my own mobo (P5Ne- SLI) I have to manually flip a switch over.

As for bios updats, yes, they can solve issues like that. And could be worth a try. Firstly check your mobo manual, see if there's an SLI switch and exhaust that option. Then you can try a bios update. Note of caution, if you haven't done a bios update before, do some research, specially on your manufacturers website. Making a mess of a bios update, could potentially brick your machine.

According to the manual there seems to be some jumpers that need to be reconfigured for SLi use. A bunch of them that are sitting between the PCIe slots.

Thanks but kudos will have to go to whoever can read the manual or find an English one! :lol:

Thanks guys, between the pcie slots there is a flip card that you turn for either sli or single card, I am aware of it as I was running 2 x gt8800s until 1 popped I then I ran just the 1x gt8800 until I could afford to buy the GTX660. As stated I cannot get the 660 to run in the 16x slot1 with either setting on the flip card and can only get the 660 to work intermittently in slot 2 when set to sli (single card setting only enables slot 1 anyway.):pfff:

hmmm. given that the mobo is old now at this stage, it could just be starting to fail. Have you another GPU you could try? If not, then try the bios update. There were some issues with certain PCIe 3.0 cards working in certain 1.0/2.0 rev boards. I can't remember specifically and it could have been more to do with AMD cards as opposed to Nvidia. But it might be the option to get your mobo to pick up the 660!?

Thanks Keith looks like bios flash is the route I'll need to go down the mb is actually only 3 yrs old replaced a p5n32sli that suffered a power chip failure. Mind you looking at the Gigabyte site the last bios upgrade has got grey hairs. but I'll give it a try, or try to find a mobo that'll take my q6600 and ddr2 as i'm not buying all that lot again until I really need to and the processor still bangs along quite nicely.
