Lenovo Z51 - Graphic Card not working

Hello,

 

My AMD Radeon R9 M375 is either not working or highly underperforming. Games like League of Legends run slow at a unstable FPS even at lower graphic settings. Graphically harder games (For example Maffia II) can't even run there is just constant lagg.

Now I think the AMD is just not working at all because while playing these games only my CPU get's hot (really hot) because I believe the onboard Intel Graphic card is working.

 

I have updated and installed all drivers, in my BIOS I have set my laptop to use both Graphic Cards. (I could only choose between either using only the Intel one or use both)
I have tried disabling the Intel Graphic card, this only made things worse, and every single setting shows that the AMD card SHOULD be active. However, it seems that it isn't active.

 

When I let my computer specs get pulled by Speccy, Speccy does recognize the AMD Graphic Card. Also the AMD driver software recognizes that there is a AMD inside my laptop.

 

Is there anything I can try to do to make my AMD Graphic card work?

 

I run Windows 10.

 

Thanks,

TimHorst

I almost forgot, I do run my laptop on high performance with the power plugged in. So that isn't the issue either.

Hi there, Tim               -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

There are two sets of graphics card in the Z51, which one is used depends on graphics load and your preference. So at idling the Intel gpu kicks in. 

You can force the discrete GPU (AMD) to run all the time, by going to bios and set it to discrete graphics mode. But this will draw more power and produce more heat, however the graphics performance will be higher.

 

Technically, the Intel integrated graphics is always active, although it is not always in use. AMD graphics will turn on and off according to need. Software from AMD called AMD Catalyst automatically switches between integrated (Intel) and dedicated (AMD) graphics, according to the application.

 

Update us how it goes.

I already have this set in the BIOS, yet while playing games I have extreme laggs and only my CPU get's hot, my AMD graphic card's tempature stays the same.

You may also try to run in safe mode to check if the freezing still happens.

 

Run a few tests from this link -

http://support.lenovo.com/us/en/lenovodiagnosticsolutions/tools

 

You should try Storage test, memory test, motherboard test, CPU test. Open Command prompt and try sfc /scannow to check if your windows files are corrupted.

 

Update us how it goes.

The windows scan result:

"Windows resource Protection did not find any integrity violations."

 

The Lenovo Solutions Centre did not find any errors either. It was able to scan the AMD graphic card.

Yet for some reason the AMD graphic card is still not being used whenever graphically harder programs are running. Only my CPU burns up and the AMD graphic cards temperature remains unchanged.

Re: Lenovo Z51 - Graphic Card not working

Your CPU / GPU might be overheating and it's throttling down - this would cause your CPU / GPU to operate in a low frequency, thus giving you low FPS.

 

If you get high temperatures, you can try to decrease the heat by:

 

  1. Using a good quality cooling pad that runs on high RPM or a better cooling in your room.
  2. Replacing the stock Thermal Interface Material with a good quality TIM like Noctua NT-H1Tuniq TX-4, or Artic Silver 5.

Update us how it goes.

Re: Lenovo Z51 - Graphic Card not working

That would be a good solution however when starting up a game it runs extremely laggy from the first second. At this point all temperatures are this normal. I'm really certain that my AMD graphic card is just not being used, only my Intel one is being used. As these games that I run should run very smoothly with the AMD yet they lagg from the first second and create massive heat inside the Intel hardware, whilst my AMD hardware temperature remains the same.

Re: Lenovo Z51 - Graphic Card not working

The AMD kicks in when you do 3D graphics, like games, CAD, Second Life, etc. When you are using Word / looking at your icons, it defers down to the onboard (2D). There is no way to use AMD all the time.

 

If you still have problem, I would recommend contacting Lenovo service centres for further assistance.

 

Schedule a Call-back for faster support

English 24 hours a day 7 days/week 

During business hours, you may also engage with live chat support.

 

Update us how it goes.

Re: Lenovo Z51 - Graphic Card not working

None of the support options work for me because my warranty is expired and apparently one needs warranty to use the Lenovo support.
