Acer Laptop: Switchable Graphics using i7 & AMD Radeon

[popeye1953]

Ahhhhh, the drivers for 7000 series cards basically suck right now. AMD needs to get off their rear end and fix them. You can go to other forums such as Guru3d and read about all the problems.

Did you go into your BIOs and set the following ?

Always Enable PEG [Enabled]

PowerXpress Setting [Muxed Fixed Scheme]

Ah Popeye knows what's up, nevermind.

I don't know whether this will help or not, but...

I have an AS8951 with switchable graphics (Intel onboard, and a 2GB GeForce GT555M).


It will use the Intel chip by default, or when running on the battery.

But you can select which to use by default in the Nvidia Control Panel.

The choices are: integrated, GeForce, or auto-select.

You can also select which GPU to use in a particular program by right-clicking its icon and
selecting ' Run with Graphics Processor '. The default GPU is indicated, and the option to
set the default is also here.

There is no need to go anywhere near the BIOS.

Strange that the Radeon-equipped machines don't have a similar setup?


Apologies if this dooesn't help anyone, just an idea.

Thanks but Nvidia machines are a totally different beast. Your ability to switch is still a function of the Bios and software. The problem is, the 7750G stock Bios sucks.
The software is similar to what you describe but with Acer stock Bios it is hampered. Many times it does not use the better GPU even when selected by software.
It is hard to describe unless you have experienced it.

 

[Katanyavich]

All good, Popeye, I haven't played with the 7750, so I wasn't sure.

Just hoped I may have been able to help.

Do hope you get it sorted...

No worry, thanks for caring. I'm good with the modded Bios. It allows me to select which card as primary use all the time regardless of program usage. In other words, either the integrated Intel graphics is the only card or the AMD card is the only one seen by Windows. Something the Acer OEM Bios does not provide. It only allows selection of a program association to which card used and hope it kicks in. Can not choose a default graphics option to use all the time.
The modded Bios enables this to where it shows up in the AMD software to choose default graphics.
Again, difficult to explain.

Yes ive done that..

I installed the modded bios, and done these two steps, followind joooeeel's post
Then i was able to choose the Ati to run constantly.
My problem is now resolved, thanks a lot

I've always had this problem with Acer laptops. Sometimes works, sometimes doesn't no matter the Bios. Will work for awhile after reboot then stop again. I found a small program called Desktop Lighter that will sit in your tray and saves having to go into Control Panel/Display to adjust.

I should add that my previous Acer's have all had dedicated video cards and no CPU integrated video. I always experienced the problem with adjusting brightness with a dedicated GPU. Seems this has carried over with the switchable graphics. Definitely not a big deal to me. Just use Desktop Lighter with the high performance GPU.

 

[umbau]

brightness working only when selected intel gpu (energy saver gpu ) when the battery mode on balanced

Day 2 on this BIOS and well I've had some minor issues..

I have the High perf GPU selected via CCC..

From time to time..VLC lags a bit, or goes into black screen..Google Chrome today froze on me, and came back, but the graphics on the screen looked very weird..

Laptop is running a bit warmer, but I guess that's expected..

But good news:
I'm running L4D2 on max settings and its perfect! BF3 on High settings perfect! MW3 as well! So..I guess I'll have to keep testing it out to see.

Hmm, VLC seems to be working fine here and I use FireFox which I've not had any problems with.
A bit warmer with the high power card of course. I just switch back to power saving GPU when I don't need the ATI card. That is the great thing about this. I'm so glad to be able to do it finally.

 

[Lak3rsFan]

Yes, I'm grateful for it, I'm still testing it out, could've just been a glitch in the files I was watching (which was the case because I went back to the Intel) and the Chrome issue could've been just because it was overloaded (Med student here, I usually have about 10-15 tabs open!)

 

[Lak3rsFan]

Now I just need to know how to overlock this processor lol..

BTW: Popeye, noticed you have the same laptop as me, did you use the second HD bay? I wanna figure out how I can go about shaving the back part of the panel. Tried putting my SSD in there, but the parts of the panel that goes to the back of the laptop hit it .

I believe I saw a special panel online for sale. Try searching.
Which drivers are you using? I'm using latest leshcat and they work great.

 

[Lak3rsFan]

I don't believe I'm leshcat, how would I check that?

 

[popeye1953]

You would know because you have to download from his site and go through some steps to delete old drivers.
What date does your drivers show in device manager? Mine shows 3/8/2012.

His site is here: leshcat blog IT Tips & Tricks: Catalyst 12.3 WHQL UnifL for Switchable Graphics

Be sure to follow the steps in his manual if you load them.
