how to enable 295 sli?

[moorebwb]

my system,

ASUS Rampage Formula, Intel Xeon x3350, 4gb corsair dominator 2*295gtx(Gainward-v2), Dell 30" 3008wfp.

I am trying to enable both of my 295's to run in sli, when i try doing so in nvidia control panal, i apply then it automatically turns it off itself? gpuz shows all 4...but performance in games is no different than one card, help?

some games arnt coded for SLI so it may just turn off depends on what games your playing mate,crysis is SLI capable with updates just google SLI games and it will tell you,altho there may be a way to turn of the option for 'let the application choose' but ime not sure

correct me if im wrong but aint your rampage a x-fire motherboard?? but do remember a thread sayin how to convert x-fire motherboards to sli! its on ths forum somewhere??

I presume it does both....let me know if u have a link on the convert...cheers

afaik rampages are x48 which means it isn't SLI, only x58 mobos are.

thats ok have you checked this link out?? your board aint on their list it just hasnt been tested does not mean it wont work!!

Despite the small current list, this modification allow to run SLI on ANY chipset, and not just Intel or NVIDIA. Technically SLI can be enabled even on a Motherboard with an AMD Chipset. Of course, board must have two or more PCI-Express slots for graphic cards

Easy answer is buy a different mobo, the answer you dont want is that even if you get it working 2x 295's dont scale very well at all, no games like that many cores. You would get better fps with 2x 285's dude.

More GPU's doesnt always work out as more FPS, surprisingly means less more often than not when it comes to 2x dual cards.

Hacked drivers are ok, just dont be expecting the best performance, as a proper SLI board with the latest drivers is usually the best way, this is pretty cool though, and it would be pretty awesome if nvidia just re-wrote there software driver for x58 for most other intel chipsets ;D
