NVIDIA Pixel Clock Patcher

[ToastyX]

I thought the SLI limit was fixed. I'm getting conflicting reports. Some said the 700-series cards don't need the SLI patch. Some said the latest patcher fixes the problem. Now some are saying it's still broken. Did the latest patcher even fix anything? Is there more than one limit? I don't have an SLI setup, so this inconsistent feedback is confusing.

If I don't use the patch, it just black screens when I try.

So without the patch, you just get a black screen when trying a custom resolution, but with the patch, it appears to work for a minute, then crashes? That sounds like the patch worked, but something else is causing a separate problem.

It might be this known issue in the beta driver:

"1379957 - TDR in SLI mode with UEFI enabled upon reboot/driver install (will be fixed in next beta release. Disable UEFI as temporary workaround)"

Enabling CSM in the BIOS would work around that.

Is there any driver version where it worked for you?
