hello,

i have the core i7 720qm
260m
6gb 1333mhz
bios a03
just got this system

when i run prime 95 and furmark together, i see a definite throttling.
when the temp of the gpu reaches 74 and when JUST about to reach 75, it throttles back and reaches 69 degrees or so. and then it again regains its 550mhz core clock and reachers 74, and then throttles back onces again with this cycle.

i think this is caused by temperature issue. if it was lack of power, the point of throttling will be rather random. however in my case, as soon as it reaches 75, it throttles. ALWAYS in this temperature.

if i let cpu at idle, and run furmark, it will go up to like 78 degrees or so. i didnt see it throttle till then. i just turned the program off after seeing that it doesnt.

the thing is that, as long as i put the temp down, i can run the gpu at 550mhz with not throttle while running prime 95. again, whenever the temp reaches 75, as SOON as it does, it throttles back. so i want to rather confirm that it is more cause of the temp, not lack of power.

but well 75 degrees is not that hot at all....

any other ideas????
