Quick question (780 Classified)

[WillSK]

So I've just got a 780 classified. I've currently got it overclocked to 1228Mhz on the core clock boost and 3305Mhz on the memory clock boost (this is via just increasing the power/thermal target and letting it fly)

I can't seem to work out what my Core clock is because it just underclocks when i'm not gaming? How can I find this out?

Another couple of things i wanted to know are

A. Is this a good overclock to start or can it be pushed a bit further just through EVGA precision ( I don't want to use the third party voltage programme)

B. Is it normal to get a faint buzzing noise from the card when it's under load?


Thanks guys!

That is normal to clock drop when you not play games on 320MHz.
You can set card to boost on about 1200-1250MHz... that would be nice improvement for gaming and memory depend how much you can, 1700-1800MHz would be excellent.
I use EVGA Precision only for games when I overclock.
Is it that loud buzzing??? Because my ACX not produce buzzy noise,
only normal air sound, on both cards.

Thanks Vlad. I'm sorry I don't always follow your posts too well but i got most of that so thanks.

Anyone else got any experience with the 780 classy's?

You can see the 3d state clocks with GPU-Z.
Faint Buzzing noise is ok, and you can actually change the pitch by overclocking/changing the voltage. also If you disable vsync, you can change to pitch with fps
The buzzing noise could be potentially coming from either the power supply (coil whine) or the gpu
