TDR and dual GPU's

[Shintaro]

Hi,

This might be useful:

I have a HP Envy M6 with 2 GPU's (Intel 4000 and ATI Radeon 7670M) until recently had a few problems with them (see the embeded crash sample, at least 1 per day).
In CCC (Catalyst Control Center) I started ensuring that I set which application could use the Intel graphics (Power Saving) and which could use the Radeon(High Performance) (See the attached pic). This seems to have settled things down.

What annoys me about HP is that I was not able to disable the Intel video card in the BIOS.......unless someone else know something.


Anyway a question, does anybody know if there exists a similar application for Nvidia? Specifically with the GTX 760 EVGA?

VIDEO_TDR_TIMEOUT_DETECTED (117)
The display driver failed to respond in timely fashion.

Unfortunately, unlike earlier embedded video, the Intel HD video processor resides on the CPU die. Most (if not all) PCs using this form of integrated graphics (Intel Core i3, i5,i7 & AMD APUs) don't have the option to disable on CPU video... At least none that I have seen or worked on...

The GPU switching feature has only been recently introduced (in the past 3 or so years) and, AMD isn't known for their great driver-writing skill...

Now for the second part of your question...

I could be wrong, but graphics switching is most prevalent in the mobile field, where battery life is taken into consideration... The second GPU you listed (NVidia) is a desktop GPU, and AFAIK, Intel HD Video will not run in conjunction with a discrete NVidia GPU for the purpose of graphics switching...

NVidia did have a GPU switching technology for desktops using NVidia chipped boards and NVidia IGP and NB chips that allowed switching between the on-board IGP and Discrete GPU depending on graphics load. It wouldn't work if the integrated video were Intel or ATI. It was an extension of Hybrid-SLI/Optimus as far as I remember.

Amd also allows an integrated/discrete X-Fire in AMD chipped boards, but still not with Intel.

Keep in mind I have been out of the loop for a while, life has kicked me in the hind-end a few times in the past year and a half...

Perhaps there is a desktop variation of the graphics switching that I am unaware of, but my research keeps leading me to the portable market.

GZ,

Thanks for the responce.

I am thinking, that because the person that I am helping had both the onboard Intel HD and GTX 760 EVGA enabled, it *might* (Actually more like hoping with my fingers crossed) be his problem with TDR crashes.

It is very interesting that Nvidia wouldn't do graphic switching with Intel HD, this poor fellow has been living with this problem for 3 years.

Cheers.

They do, but on the notebook front. As I stated before, I could be wrong. I was very up to date with NVidias Optimus technology back in early 2012, but then life took a turn down a dirt road and I am just now getting back out on the freeway.

As soon as I get the chance I will try and look into it. Perhaps someone else has input.

 

[Shintaro]

I appreciate your advice. I have seen the TDR fault around quite a bit. So it would be a nice-and-easy solution for desktop machines.

I hope it all works out for you.
