Zero Core probably not working. Why?

[bowman]

Hello Everyone!
I have recently bought an R9 270X VGA, and i doubt that the zero core feature is properly working in my system.
I have uninstalled the old one, and istalled the latest driver properly.
After the monitor goes to standby state, as far as i know the fans on the VGA should stop spinning, meaning the GPU enters zerocore state.
However this not happens, as the phase indicator leds, and the fans all remain on after the pc goes standby.

Do you have any ideas what could cause the problem?
Also i am using PCI-E 2.0, not 3.0, so i dont know whether this low power state works with 2.0. (might be the problem?)

Any suggestion is helpful for me,
Thank you!

isnt zero core for Crossfire systems to disable the second card?

No not at all. It should also work with a single card configuration as far as i know.

Further ideas anyone?

don't you need to use that in combination with an amd apu so it'll use the onboard gpu instead of the 270

I've read that it might not work if you're using hdmi iirc

It switches off your second card when in a long idea state but not the first, however power consumption does decrease to next to nothing

Nope, nothing is being displayed then you dont need a working gpu.

I am using DVI output.

Yes it does switch off your first , or only GPU. (at least it should , as in my case)

Anyone else?

Might be best to hit up the AMD forums, there's usually a few techs that hang out there.
