Tri-Sli

post #1 of 5
Thread Starter 
I am wits end.

I had a pair of Evga 1.5 gigers 580 gtx's and decided to buy a third with my new system update. I bought a used card off of eBay but didn't realize it was the 3 gig version until I installed it.

I did a little searching on the problem and found the nvidia response on their sli zone which recommended using the coolbits registry hack. I downloaded and installed the reg mod and presto the nvidia manager gave me the option of tri sli.

Here's the problem although I know have the option to enable tri sli the configuration is not stable. The heaven benchmark crashes out in less than 10 seconds. I've verified the registry entries and have even tried both hex settings of 18 and 1a but to no avail.

I've contacted evga and they told me they don't support mismatched memory on sli setups.

Does anyone have any ideas? Its a tri sli setup with nvidia surround.

As it stands now I'm just using a dual sli with the third card as a dedicated phys-x. Sort of waste really.


Thanks for any help or input

Pat

what are your temps..trisli gets really hot and would def cause the crash..i had sli refrence cards and they still got very hot..and they were 670s..i could only imagine 3 580s.
