is there a way (tweak) to lower the power consumtion for this card when in IDLE? (150W for idle is not little, but i expect this card to arrive next week

)

greetings

PS: yeah, finally i get it (but still not for the price of 170, but they offered me a price drop of 55 euro -> 230euro instead of 285)

Perhaps try to tweak the PowerPlay options, or maybe reduce the clocks. But then again, I'm sure you understand that this card is high-end and that it is to be expected that it'll consume a lot of power.

With ATI Tray Tools you could underclock it in 2D modes.

will try when it arrived! thanks!

@imodintel, i know that it is highend, and that does not mean anything about idle power consumption

my monitor is high end too, and consumes 1W in IDLE/powersave

I know that, but it is normal that LCD consumes nothing (very little), the amperage required on that card is what makes it so power hungry (imagine if the GPus would still be on 90nm process)

I underclocked mine 4870 using ATI Tray Tools to 250/300 (GPU/MEM) and 1.089V in 2D, power drain down to 14.7A (or 14.9 - don't remember exactly) from stock 2D 20.1A (according to the GPU-Z), also temps down to ~40 C at idle in 2D.

i installed ati tray tools but got errors, it says low level driver cannot be installed...
when i go to low level installer it says its installed but cant be started.
will look at next reboot if it works...
hope so

if you are using Vista X64 just remember to boot up, press F8 to disable driver signature enforcement.

will this work for ever or do i have to press f8 every time??
