Is there any way to have the card downclock the RAM when not in use like it does if only one screen plugged in? Even when the second screen is turned off it runs at max speed, to get it to downclock to 300mhz i need to physically unplug the cable.

Should post it under "The AMD Drivers thread" I have seen other people posting about this but as brennen said im not too sure if there is a fix or not.

Yeah it's been around for an age, i just assumed they would have fixed it by now. Bit annoying as the second screen is a TV so it's not on very often but causes the card to draw more power than it needs even when not in use.
D'oh I should have looked in there first. Seems the only 'fix' was to use a 2D profile afterburner, which doesn't appear to change anything.

It's not a bug so it won't get 'fixed'. Running two displays requires more resources so the memory moves up into the next clock state to compensate. If the memory ran at 300Mhz you could get flickering or other unpleasant issues. Having the memory run at full speed does not make much difference to the power draw, whereas running the core at full speed to compensate would.

My old 7950 does this with two screens connected, its just designed to function that way.
Not entirely sure why this is the case but I've read that running the memory slowly while trying to power two screens would cause flickering issues, so they are designed to keep the ram running higher.

Matt beat me too it
