For Snowcrash and anyone else that might be interested.

The ATI HD4890 is a large 256bit card that under full load draws quite a lot of power, to help get over the high power consumption, particularly when the card is at idle, it automatically underclocks its GPU but it doesn't underclock the memory, that is a little unfortunate as the RAM requires plenty of power to run at its default speed of 975Mhz.

So how much power can we save using the ATI Tray tool and underclocking both the GPU and RAM to a speed that will be fast enough for every day mundane PC tasks including full HD video playback in Windows 7.

The answer is 46 Watts.

NOTES:
The power readings are for the entire PC (tower case).
The readings are at idle, no heavy graphics application was running.
The canter reading was the card automatically underclockling its self.

Don't forget to look at the slide show further down the page.

I've been experimenting with the speed of my CPU, wanted to see how slow I could run it but still have enough CPU power to do the every day mundane tasks in Windows. (Not gaming)

Why?
To save power and money, make less heat and at the same time maybe extend the life of my PC.

I successfully got it to run as low as 1.2Ghz @0.85 volts, but at that speed there were signs of a slow down, the worst was in media Center where the PC couldn't successfully keep the video playback of HD content running smoothly.

I have ended up with a core speed of 1.6Ghz (roughly) and a core voltage of 0.96V, at this speed the PC seems to run almost as quick as default, not really any noticeable slowdown and HD video playback is perfectly smooth.

I have achieved this underclock by setting the multiplier to 6 instead of 8 (the default) and then reducing the FSB until I got to 1.6Ghz.

Then reducing the CPU voltage to a stable place.

Then reducing the RAM voltage to a stable place also.
