No SLI enable? (Solved now :D)

post #1 of 12
Thread Starter 
Just put in my second 460, and it shows up and everything, just afterburner shows that it never clocks up during games and kombustor, also there isn't an option to enable SLI in the nvidia control panel, only PhysX.
I already did a clean install of my drivers.

What do? I am going to restart the computer and I'll be back in a bit.

its not the bridge, as you can run SLI without it.

first plug your monitors on one card first, why do you have 1 plugged in each? second in your Nvidia Control Panel it should have an option next to the physx option to enable SLI or disable SLI, or at least that is where it is for me

I am not home so I cannot check on my computer

update your video drivers to current release?

google?

I had it connected both to one originally, changed it to see if it changed anything lol
the option isn't there after reseating the bridge and restarting with clean drivers

Yes, do connect both monitors (Samsung and Dell) to the primary card.

If you have older cards (8 and 9-series), you might not need a SLI bridge for SLI to work.  But the GTX460 is modern enough to require a connector.

Well now that I changed the monitors to one card I'm going to restart again because the option still hasn't shown up :|

Still nothing after restart with bridge reseat and driver reinstall along with both monitors being on 1 card

the card will clock up if I apply afterburner settings so it's not a faulty card

Hmm here's a crazy idea that actually may explain your problem...

The P55 SLI mainboard has two x8 slots and a single x4 (for other devices, NOT GPUs). Any chance you installed you second GTX 460 on the x4 slot (the black slot?). If so, no SLI is enabled, since it's not a slot that included in the official SLI support, so if it's actually the case, install both cards on the grey PCI-E slots.

And after all, that's may be not a crazy idea, since I saw someone that tried to do that (installed on a x4 slot instead of the actual x16 @ x8 to make a bigger space between the cards to keep thermal perfomance better. Of course it didn't work, since only two slots are compatible with SLI officialy, the x4 is for other devices or a PhysX card), and that solved his problem.
