Crossfire

[bisurge]

I recently bought a laptop that has a 6520g integrated card and a 6650M dedicated card. AMD Crossfire is using the 6520g as the primary card, although the 6650M is the better card. This is probably to save power. However, I want to make the 6650M the primary card, and I can't figure out how; I've updated my driver, but there's no option to make the 6650M the primary card. I've searched the BIOS too, and there's nothing there either.

I'm using a Lenovo Ideapad Z575.

They work together to produce the same image.Changing the primary display card won't improve performance.

Well, maybe you can answer a slightly different question then, that would solve my problem.

My computer runs very slow whenever it "switches" to the dedicated card; oftentimes it just freezes. I don't know if my dedicated card is DOA'd or if it's a driver problem (I only got this problem after updating the driver). This problem doesn't seem to happen much when the AMD VISION Engine Control Center is not installed, but that's probably because without it AMD dual graphics is off. But will both graphics cards still run if I uninstall the VISION Engine Control Center? Is there another driver I can use to the same effect that doesn't freeze my computer?

They are meant to be used together not separately otherwise they wouldn't have included a dedicated card.Try uninstalling everything GPU driver related with driver sweeper,reboot and then install everything again.If everything was working fine before you updated the drivers then it points to a driver related issue.Also are you sure you got the right drivers?

Laptops, unlike DIY computers, works better with supplied drivers. IMO, unless you have problems with laptop & recommended by the manufacturer support ( downloaded from their own website), supplied drivers should not be replaced with generic ones.

Actually my laptop is this one: http://www.newegg.com/Product/Product.aspx?Item=34-246-328&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=2#scrollFullInfo
I don't mind using both, but I just want to be able to use my laptop until I resolve the issue. I did a Device Manager install for the 6650M, but that also invalidated the VISION Engine Control Center.

I am using the supply driver, albeit an updated version of it.

Small update: Thanks purple stank, I reinstalled my drivers, albeit in a different order, and now everything is working fine.
