Finally my ears can rest.

Got new XFX 7970 BE today to replace the whiny one smile.gif This dont seem to have coil whine other than in very high fps scenes ( over 1000fps ) which i still count as normal behaviour, as it only happens in game menus etc it is not really disturbing. Havent tried OC yet with this new card but noticed that this has lower voltage than old one, this has 1.112v when old one had 1.175v.

Ok, the -xcl switch is just to tell AB to create new modified Powerplay Tables in the registry. All it does is unlock the overclock limits of Overdrive. Note you won't be using Overdrive at all. You'll instead be using AB but using AB just as default with only the check marks for unlocking voltage. Don't do anything in AB's config file, that method is for "unofficial method" whereas you'll be using "official method."
When you add -xcl to the AB shortcut, it doesn't run, it merely imports the Powerplay Tables as mentioned above. Once that's done, you have to then remove the -xcl you added, and reboot. Upon reboot, you can open up AB and overclock like normal.
**There are a couple caveats with the -xcl method. The most annoying is that AB cannot edit the Powerplay Tables of more than 1 card. And that 1 card is only the active card so if you have crossfire you will have to jump thru some hurdles. There's a trick to add all the Powerplay Tables for ppl in crossfire in that link.
**The other annoyance is that you will have to redo the -xcl method after each driver install.
**Also, you will need the clock control files.
It's also a good idea if you are crossfired, to do this on a cleaned registry so you know which Radeon folder to edit.

Thanks alot following your guideline worked, Happy Overclocking smile.gif

I love my gtx 680 sli, but I want the extra gb of memory and add 2 more screens to my portrait set up.

The Lightnings are fantastic cards but have an odd output selection. You'll need DP monitors (or adapters) as the Lightning only has 4 mini-DP and two S/L DVI connectors....

Proud new owner of ASUS HD7950 DC2 TOP.. biggrin.gif

Came backt to ATI after 2 years..

My card has 0.993V stock voltage, pre overclocked to 900MHz core (1250Mhz memory)..

Now I'm running it @ 1000/1375MHz with 1.024V (+0.031V) and max temp in games is 60C (fan hits 40%) wink.gif

3DMark 11 - P9447

hwinfo or gpu-z will give you proper readings

Fire up 3dmark for example and check max voltage afterwards

Hey, KingT, whats up? In my system that card could not do 1 GHz at that voltage, very interesting, maybe because i am GPU stability fanatic, i test my stability in over 20 games/apps.

That is one bug, solution is to delete MSI AB.
Disable AMD overdrive, install MSI AB, and when he ask for reboot, do it, then it will be fine.
Sorry for double.
