Hmm. 900 I guess is just the limit of your card...

Although I still think it should be able to hit 920 ~ honestly you won't really notice a difference I'd say once you hit 900, anything after is mostly for bragging rights.

What are your specs?

60GB SSD + 1 TB HDD
Moterboard is an MSI P67A-G45 B3 rev
MSI twiin frozr II GTX 580
And case is a NZXT Phantom
I didn't do the CPU overclocking.

Strange.

I guess it's just the limit of your card.

Those specs are more than enough to handle a good overclock on this card, which makes me wonder what is the issue.

I'm going to stick with the fact that it seems your cards just have a cap of 900MHz before going unstable. All cards are different and they overclock differently.

It's up to you if you want to try to increase the voltage. Doing so may fry your card if you are not careful. Personally I don't really recommend anything past 1050mV which is most likely the max you can turn it to before needing a BIOS flash to unlock the voltage even further.

But it's your choice. I still don't think that you should be at 1100mV for a mere 880MHz, but as I said, cards overclock differently, and I guess yours seems to like power.

EDIT:

Your temps are a little on the high side, you might want to increase fan speed to a higher digit, rather than leave it on auto.

Or you could set fan curves using Precision.
