Dedicated Graphics Card wont turn on?

[lukey2k10]

it's a hp G series, A8-3520 and 6620G + Dedicated 7450m and firstly, i installed CCC from AMD so it then let me open " configure switchable graphics " so i set my Exe's of my Games, IE Skyrim to " high performance "

So i open Skyrim ( high detail ) on window mode and then open " AMD system monitor " so i can keep an eye on the % usage of both GPU's and ONLY the 6620g is used, 98-100% but the 7450 never kicks in, So then i noticed that Device manager and AMD system monitor says the 7450 as " 7400 series " so i go on to update driver via Device manager and now it shows 7450m yet it still wont kick in! And now it has that flicker at the top

Make sure that you're using the drivers provided by HP and not the generic AMD mobility ones. The generic mobility drivers sometimes have problems with switchable graphics

aha, that could be the problem, i got it of AMD's website and now that ive un-installed CCC the flickering has stopped.

So should i download from HP's website as the laptop never came with a disk.

insttalled the CCC from HP and it's got rid of the flicker but still, the 7450m never gets used! the 6620G is on 100% but the 7450m just stays idle

Make sure you purge the old graphics driver completely before installing the one provided by HP. It installs separate drivers for both the integrated and discrete graphics and a mismatch won't work.

tried that, still the same.

when runnign 3Dmark the 7450m does then work at 100% with the 6220G but any game the 6620G is on 100% and the 7450m just idle as usual!

Are there any application profiles available? I've never tried the hybrid graphics so I don't know how well they work

As in Catalyst? There's Engine CC which i have enabled Crossfire and chosen my exe on high performance but ive been trying to find a way to just use the 7450m as i don't see the point in the laptop using the 6620G on 20FPS when it could use more power for high FPS

FINALLY! i just thought i'd post how i fixed this as i myself have been searching this forum and google since friday, so just incase anyone comes across this topic they'll know what to do.

Played around and thought i'd see what " fixed " switchable graphics does in the Bios instead of dynamic, right click on desktop t go to Graphic Properties and there it is, the option to use either the Intergrated or the Dedicated for everything and now finally im getting 30+FPS on skyrim

Good find, I'll keep that in mind when this problem comes up again
