If I wanted to reset my 4850 idle speeds to save power, could I do that?

[dug777]

I miss my 3450's epic 60W total machine draw at idle with my Q6600, now I have the 4850 my idle is 108W

No doubt part of these woes are the 2d idle clocks of the 4850, which seem way too fast...

Thoughts? Suggestions?

I tried to do this with RBE (Radeon Bios Editor). It didn't work out.
It seemed to ignore states 1 and 2. But I know it's not ignoring those two states, since the voltage drops and those were the only two states that had reduced voltage in RBE.

I configured RBE for:
0: 625 / 993 / VID
1: 250 / 550 / 1.05
2: 250 / 550 / 1.05
3: 720 / 993 / VID

Doesn't work =(. It idles at 625 / 993 / 1.05, which is none of those states, so I don't know what's going on.
the overclock works though, it does run 720 in 3D apps.

I know people have been able to change idle with RBE, but I apparently am too much of a noob with it.

If you're able to figure it out, please PM me.

My system also shows 107-109W on a Kill-a-Watt at idle. (e7200 OC + 4850 + P45)
Other systems idle as follows:
e5200 / P43 / 7900GT - 100W
3400+ single core Athlon / NF4 / x800XL - 99W
3000+ single core Athlon / Supermicro server board with and AMD server IGP chipset / 3Ware IDE RAID card (no raid, just using it for ports right now) - 50W

There is an official MSI bios that has really low idle 2d clocks. You could try mimicking those settings in your own card's bios or flashing the MSI one. Sorry I don't have any specific links but it's something to look for.

Edit: I think this is it:

Did you try this dug? I didn't have a chance yet.

I had to flash to the msi bios on my spahere to get it to run stable
