Hi,

I recently set up an SLI system consisting of two Nvidia GTS 250 1GB (one Galaxy and one PNY). My computer recognises that they're in SLI and everything seems to be in order.

However I have not noticed much of an improvement in terms of performance, and when I run System Monitor in the background while playing Skyrim I notice that GPU 2 (the galaxy card) is at 100% and GPU 1 (the PNY card) generally hovers around 0% maybe jumping up to 5% some times (if that).

I was just wondering, is this what's supposed to happen (I'm not used to SLI at all, this is the first time I've tried it) or has something gone wrong, if so, what has gone wrong and would there be a solution?

Thanks,
Jonny.

There is an option in the nVidia Control Panel to enable a logo to be put into the corner when SLI is enabled. Note also that SLI (and Crossfire as well for the AMD/ATI folks) is only in effect for Fullscreen applications which use Direct3D Exclusive Mode. That means you should check your Skyrim settings to make sure it's in Fullscreen not Fullscreen Windowed.

Thanks, I've tried displaying SLI visual indicator, but nothing came up, and yes, I am in fullscreen mode.

If nothing came up, SLI is not enabled or not working. From there I'd begin with the basics, troubleshooting physical connectivity, which slots the cards are in, whether you have your SLI bridge connected correctly, if the drivers are configured properly, etc. Use Furmark to test in fullscreen mode, it'll give you on the fly readings if you have GPU-Z installed.

Thanks for the tips, turns out I needed the latest beta driver from nvidia, they've only just made an sli profile for skyrim within the last week or so.
