Hello. I've been lurking here and putting what I've read to use with my mining rig. I'm still tweaking but ran into a problem I'm at a loss to explain.

My rig has been running non-stop with hashrates around 450. Yesterday it dropped to 360 - no changes to cgminer.conf.

Is there something wrong with the GPU card (it's a TwinFrozr 7950)?

Thanks for your feedback.
