G505s GPU not used, only APU

2015-12-13, 17:46 PM

Hello

 

I have a Lenovo G505s with A10-5750M (HD8650G) and R5 M230.

 

My problem is the following:

I installed AMD Crimson Software and none of my application use GPU, only APU.

I don't know how force to use the GPU or work in Dual Graphics mode.

So my question is:

How to resolve this problem or how to use the GPU or the APU with GPU (Dual Graphics mode)?

 

The OS is Windows 10 Professional (64bit).

 

 

Thank you all replies in advance.

Update:

I tried AMD System Monitor which told me I only use the 8650G only.

About drivers:
I used driver from Lenovo site, and latest GCN and non-GCN drivers from AMD site. (I tried latest Catalyst too).

Nothing works, the laptop only use the 8650G.

The AMD guys told me trying at Lenovo support.

I don't know how to contact with Lenovo Technical Support, because my warranty expired.

I create some test and I don't know why, but when I use all (two) DIMM slot, the Dual Graphics stop working.

 

I tested with different DDR3 RAMs to exclude memory problem, and used several types of video card drivers.

 

First the BIOS reserved 4,8GB memory for hardware (that I don't know why), but second time, when I switched the OS Optimizer in BIOS to Other (the original is Windows 8 64 Bit), the OS recognized all memory (8GB), and the hardware reserved memory is only about 800MB. But with both setting, the dual graphics didn't work.

 

The BIOS version is the latest from Lenovo site (maybe 3.0).

 

What I am doing wrong or maybe the BIOS do something unusual?
