Seems the extra 500Mhz (1GHz effective) mem contributes about the same in 3DM11 as an extra 26 MHz core freq.

oh yes... please what voltage for +1000 mem?? tongue.gif

Stock smile.gif It will do +1050 on stock voltage, I just run it at +1000 because it does it easily and I think 256 GB/s is probably enough bandwidth so the core is not limited.

That's gotta be the best clocking gtx680 when it comes to memory. I'd be happy with that beast of a card just for the bandwidth capability.

Indeed. That's what I said. No one can touch his memory, even though I've seen someone run 8000mhz before, it was never on the stock voltage.

So, cryptik, what does the memory run with +100mv? devil.gif

Isn't that obvious?

Yeah seems I got lucky with this one and the mem. I tried up to +100mv and it really makes no difference, I think I'm at the limit of the memory controller at +1050. The mem itself would go higher by the looks of it but no amount of voltage will get any more out of it.

Apparently the controller was what nvidia and AMD struggled with, even 6GHz was an achievement from what I read.

All these good cards floating around is making me want to take another stab at the lottery smile.gif

Done some benching recently on air. Water to arrive soon.





@CryptiK How is your scores soo high? i've got a 2500k @4.8Ghz and your score walks all over mine. Though i couldn't get mem over 730, with a decent core. Had aux on +0 and mem on +10 atleast. What is recommended for aux for stability and good bench runs?

Your Physix score is way lower, I don't know what you can do to increase it on a 2500k, disable any unneeded processes, increase CPU and Mem clocks, increase blk, your graphic score is OK.
