with 720/900 / 0,940 v? how high your temparature? its stable???
how about fan setting? how fast you set this one? auto or what??
Well, currently I'm running 720/900@0,92V, temps in idle stable at 65/70C° with cycle of 65/70% (browsing at that clock fixed) and up to 86C°-91%fan-cycle gaming with optimal performance settings (that however enables a 4x AA filter from game settings).
There is an improvement of 3-5 fps at 760/950@0,94V but temps also rises a bit and fan ramps up even more, I don't like it and it doesn't worth up to me.
However 725/900@1,00V are the default settings for a 6770M which has a 30/35% performance gain over 6750M by default, running (nearly) those clocks @0,92V is not so bad after all, it allows to play a bit better without overloading excessively the system, my first worry is that the cooling system is not engineered to take care of a huge load of heat, this is the reason why in the last firmware they've modified the throttle cycle of the cpu, for example, I do believe even the gpu could have been pushed more in the 02/07/11 EFI release, I've bought mine with the 04/22/11 already onboard and I'm nearly sure there is no way to switch EFI back to the previous release, unfortunately.
In few words there is no enough airflow inside to push the stuff to its limits CONSTANTLY, a test could pass but, to tell it all, for regular use the clocks&voltage I've set up are just a bit higher to what they should be to be sure of having nothing to worry about at all, unless for someone who's used to clean his rear with money, however...
@goldsaint:
unluckily my memory cannot withstand 1000Mhz neither at 1,1V and even in that case I didn't buy a MBP to microwave chips
I'm smart enough to set up things correctly but in another excess of jinx ATT seems not to have the wish of setting fan speed manually in ... a utmost line, no way.
In a bottom line I thank you for your help but you quoted my post in which I was trying to help joecool99 in setting up the latest drivers, that said, I've no troble at all with my system besides the fan glitch and, however, the fan MUST stay in auto.
For those ones getting errors or black screens trying to find optimal freq. with the ATT built-in artifact scanner, it's to be said that APM (powerplay) doesn't kicks-in the 3D frequencies if you start from 100/150@0,9V thus it will lead at a black screen, it's always a correct thing to start from at least the default clocks 600/794@1,0V, found the highest clocks backtrak a bit and start to lower voltage, in my XP even keeping a fixed rate between gpu and vram clocks helps to gain performance with less heat.
Hope it helps.
