12.11 Beta + 12.10 WHQL 7xxx Reference User Idle Clock Bug Fix

[LtMatt]

When installing these new drivers idle clock speeds are not working properly. What used to be idle clocks of 300/150 is now 500/1375 or lower depending on your card resulting in higher temps and a louder fan usage.

A fix has been discovered that will allow you to use the new drivers and also still benefit from having lower clocks until AMD release a hotfix driver.

First install the drivers+caps.

Once that is done start up CCC, go to overdrive and apply 300 core and 150 memory clocks.

After this go to preset, add preset, name the preset idle, put the tooltip as 2dclocks, under location leave all items ticked, then assign a hotkey. I used F5. Click save.

After that go to preferences in the top right of CCC, then hotkeys. Click idle and go to edit. In with Hotkey press F5, Click ok.

Now whenever you quickly need to apply idle clocks, just press Alt+F5 twice.

I use this after ive finished playing games and running my overclocks using afterburner in order to get the cards to clock down properly.

This also corrects the voltage being too high.

^^^ LOL

Lol, good thinking.

Run for the edit button, Alt was the default key CCC chose.

Have you tried the beta3 released this morning?

Yes, that has the same problem.

Sheeeeeeit, I'll just disable ULPS for the minute.

That's not an option for me, i treasure my idle clocks and zero power usage while idle.

I've figured out what causes the (idle clock bug) problem. Its the memory.

Once windows loads start up ccc go to overdrive and set the memory clock down at 150.

Now the 2d clock is working, correct voltage core and memory clocks set.

Now in ccc put the memory clock at 1205, suddenly the card gets stuck in a different mode where the voltage increases to 0.9 the core gets bumped to 500 and the memory stays at 1375.

The card voltage and clocks will never clock down unless you manually set the memory down below 1205. The memory will stay clocked up though unless you put it back down to 150.
