7950 Kh/s rate dropped from 500+ to 300+ today

[alxs]

yesterday was running fine at 500+ and now today wont go above 350.

Is it possible something happened to this card?

None of my settings have changed, just did this out of the blue
Its a Sapphire 7950 2L or 3L

Temps = ?

[alxs]

Same Power supply, its 850W.  Not sure what temps were yesterday, but right now under 80c.  Was running hot like over 90c a few days
ago until I got another fan.  Is it possible overheated and now wont run at a decent hash rate anymore?  Its literally like got up this morning and the hash rate had dropped.

Try restarting your PC, reset the overclock settings apply them, restart again, and then apply whatever settings you had before.
What i've found with my cards is sometimes the drivers crash and act screwy, or the overclock is pushed too far and it defaults back to lower settings till you trick it

Thanks phrozenspite, thats exactly what it was.  Driver must have crashed, restarted pc and all good again!

If the driver crashes, it means you're not stable. I'd recommend lowering your overclocks.

I'd recommend testing stability with a 3D benchmark in a loop for a few hours.
