Crossfire Problem

[L0rdMike]

Got my 2nd 5870 yesterday and I have a problem with the 2nd gpu not clocking down on idle.

Anyone seen this before?
Is there an easy fix for this or is it normal?

Thanks.

There is a bug with 10.12 drivers with multi GPU downclocking 10.12a may not have this problem.

Tried an older driver and still does it.

CCC reports the card as 000MHz.

Well that's a total down clock

Well that's a total down clock

But GPUZ MSI Afterburner all report it running fullpower.

Loading up GPUZ does make it downclock for a min but goes back to full power unless you reselect the GFX card.

Try 10.12a if that does not work then use 10.10e.

Tried both and exactly the same.

CCC for my 2nd card is blank temp = 0C clocks = 0 unless I load up GPU Z then CCC will show some values for a min then back to 000.

That maybe correct as its not being used so its shut off.

I seem to remember my 5870 xfire setup having the same issue
As I understood it only the primary card would down clock, the secondary card would always stay at default / clocked clocks
