Lenovo G505s Crossfire / Dual Graphics?

2015-06-08, 18:26 PM

I was wondering if the Lenovo G505s is compatible with AMD CrossFire or some sort of dual graphics.

Here are the specs/website:

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16834312829

 

-AMD A10-5750m Quad-core 2.5 GHz / 3.5 GHz (Normal / Turbo)

-AMD Radeon HD 8650G

 

I know that if you check under "Performance" or "Gaming" there is supposed to be a tab that says "CrossFireX" or something of the sort and that there is a sticker on my computer that says Dual Graphics, but nothing seems to point towards dual graphics. It even says under device manager that there is only one graphics card. I tried the graphics driver under G505s support and the latest drivers / beta drivers (And CCC, obviously) and CrossFire does not appear anywhere.

 

As an avid gamer, I would do ANYTHING for better performance and the G505s seemed like the best choice by far for my price range. HELP!

 

-Sam

 

EDIT: On GPU-Z, it says that CrossFire is disabled, as if it COULD be enabled.

hi Sam,

 

Welcome to the Forums.

 

The G505s comes in two variants, one with an Integrated Graphics (iGPU) and one with a discrete graphics.

 

The newegg item that you posted uses an AMD Radeon HD 8650G graphics which is integrated to the 
A10-5750m CPU.

 

AMD A10-5750M specifications

 

Sample system with discrete GPU:

Model #: 59378837

 

Edit:

Text link description

 

In addition, the dual graphics on these systems are not meant for crossfire use but for switchable graphics. The integrated graphics being used first for power saving and automatically switches to the discrete graphics for applications that demands more GPU power.

 

 

Regards

Let me correct myself. The G505s that I own is EXCACTLY like the one you gave as an example but with an A10-5750M CPU. The 8650G is leballed but it does have the discrete graphics. (Radeon HD 8570M)

 

I'm not questioning your experience and wisdom but are you SURE that it is not possible to enable crossfire, as when I go to enable SDI/DirectGMA under FirePro it says that if I follow through that it will disable crossfire?

 

And if this is the case that it is not possible to enable crossfire, is it possible to manually pick between the HD 8570M and HD 8650G?

 

EDIT: The model number for my specific G505s is; 20255

hi Sam,

 

I checked the internal parts on the newegg link that you posted below, Machine Type Model (MTM) 59373010, and this item doesn't have a discrete graphics (AMD Radeon HD 8570M).

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16834312829

 - Link to picture (parts list)

 

So I compared it to a G505s (MTM: 59378837) with a discrete graphics:

 - Link to picture (parts list)

 

Perhaps you have a different MTM on your G505s Model 20225 (the MTM usually tells the difference).

 

In addition, although you have dual graphics configuration, the BIOS is setup by default to allow only  UMA (Integrated) or Switchable Graphics configurations. 

 

If your system can choose to what GPU can be used, you can check this by looking into your systems BIOS > Configuration Tab > Graphics Device
