reformatted/DL Ntune and no sli option

[Da Pure]

Hello,
I recently Reformatted harddrive reinstalled everything games etc.... Installed Ntune and I have options missing like performance settings and most important to me is the SLI option, I didnt think it would matter but apparently im not using both Cards because I seem to be getting 40 less Fps in game. And ive used regcure/downloaded Ntune about 20 times and still those options arent there.

specs
windows xp 32
intel quad core Q6600
westerndig raptor
4 gigs corsair
2x 8600 gt 512
650 watt thermaltake psu
Asus P5N-E SLI 650i

PS thank you in advance for any advice

Not sure about this, but look in your bios for an SLI option.

Probably won't find any SLI options in the BIOS. When you install Ntune, you have to accept the license agreement. That's why all those tabs aren't there. There should be one along the lines of license agreement. Once you accept it, all your options will be there.

No matter what i do with Ntune i always have my SLI option.

[Da Pure]

thankyou for the responses yes i have accepted the end user agreement. Still no changes went into bios and under advanced PciPn settings it says

x-sli memory option not detected


So im wondering if something isnt reading both my cards ive checked device manager and all drivers are downloaded and up to date. Still at a loss and more concerned now with the memory option not detected for sli ?

My apologies the sli memmory option not detected is in jumper free confugurations in the bios

and In PciPn i changed the primary display adapter option from pci to Pci E

and i uninstalled ntune ran regcure reinstalled ntune accepted enduser and still no SLI option?

Do you use dual monitors?

Also, dont use Ntune, just use Rivatuner. Ntune is a hassel to me right now.

[srpeters18]

Don't worry about the SLI memory, it has no bearing on SLI. Its for memory that has been tested to run faster than 800mhz and is 'certified' as SLI ready. Its a marketing ploy and won't affect if your cards will run in SLI or not.

[Da Pure]

No I'm not running dual monitors. My temps for my cards are 66 c and 48 c so apparently one is def not running.all drivers are installed there both showing up in device manager, But only one is being used ? Im stumped Thankyou all for the responses so far

Is the SLI bridge properly secured ? Try this.

1. Uninstall Ntune & your display driver.Use Driver Cleaner if needed.

2. Remove the SLI bridge & plug it again.

3. Install display driver,enable the SLI option if that exists & then install NTune & see if the SLI option comes.

[Kougar]

Unless I'm mistaken you need to enable SLI first in the graphics drivers... then it should show up under Ntune.

[Da Pure]

Hey you took me down the right path!!! When I reformatted it automatically installed the latest drivers through windows. When I read your post I said hmmm
maybe I should just stick my cd in and dl the other drivers. And Eureka SLI options performance options . I ve got my fps back and card temps are 64c and 61c under load. Alot closer than before lol. Thankyou all for your posts . Big smiles for me:grin:


PS. I honestly dont know why you do have to have the sli option enabled if its not there. For the cards to work you think they would just both work?

[srpeters18]

Cause of the people that use two cards but no SLI.

I would say more computers use 2 cards running not in SLI to run 2 montitors then computers use SLI.

Wait so Windows was downloading and using the drivers? That was your problem. You needed to go to Nvidia.com and get the latest drivers.
