GTX 1080 SLI not boosting after enabling or disabling SLI

[proloser2]

Hi all, got a couple of 1080s the other day. All working fine except when I disable or enable SLI, unless I restart my PC, the core clocks get stuck at 658mhz. It's not a scaling issue as I am using the Valley 1.0 benchmark for testing this bug. Upon restarting my PC, both 1080's boost to ~1940mhz when running the benchmark.

I'm running the latest drivers at the time of this post, Is this a known issue with them? Would it be more likely a hardware or software issue? I really don't want to have to return these cards and wait for a replacement :S

Thanks

Worked it out a while ago, forgot to post answer here for anyone else... Afterburner was not updating the GPU core speeds after enabling SLI; restarting the app showed the correct values.
