H!
I have an HD 4870 (Sapphire 512mB; I might as well add, a September 2008 model - so old ). As you know, the stock clocks are 750/900. Somehow, I recently installed this card (this month).
While on desktop, the core clock comes down to 500. As soon as a 3D application is opened, the clock jumps to the stock speed, or the overclocked speed. Memory clock remains the same.
Now here, what I have done is, that I have UNDERclocked it. I have the card underclocked to 500 core, and 450 memory, permanently (applied profile).
Now this is a good thing with the card, that as soon as a 3D application launches, probably the memory clock also adjusts automatically to the stock speed. (Otherwise I wouldn't be able to play Terminator Salvation and TR8 at 100+ frame rates with my E2140 @ stock 1.6ghz!)
At stock speeds, this card is supposed to draw 165 watts maximum (support ticket from Sapphire). But support people don't tell the minimum wattage consumption. But I understand that higher the clock speeds, higher the wattage consumption.
Can anyone tell what is the wattage consumption of my card at idle in the current scenario?
Thanks
