R4 upgrade 880m performance issue and heating...

Recommended Posts

Hi guys, Angelus a new t|I member. I begin by apologize for my bad english, I'm French, and I don't speak (or write) in english since a long time.

So, I have m17x R4 with 3D screen, 8GB ram, a 3720QM, a GTX 880m ( upgrade from the 675m) a SSD and a HDD for data.

I've installed the gpu last evening, mod the .inf and it works well. Except 3 little things....

  1. My performance never exceed 20/25 fps ( I've tried with Planetside 2, in high setting and medium setting, it's the same fps value and worst than the 675m)
  2. The 3D vision driver doens't recognize my display as a 3D vision Display... ( And i'm sure it's one, i used to play in 3D with my last GPU)
  3. The idle temp is 70°C min and about 93° in charge.....

Does somebody have an idea? I don't know what i can do.

I've heard about two things :

  1. the latest nvidia driver limits the power of the gpu. ( right or wrong?)
  2. Alienware loves put own vbios inside the gpu and oem gpu could not works properly.

Thank you again for helping, and thank you for reading my "pretty" english! :single_eye:

It's resolved... I have really good performance now! between 50 and 60 fps in star citizen very high config, and the same in planetside 2 in ultra config.

A question, do you think a custom VBios could really increase the performance? And somebody could explain me the advantage to flash the laptop with an unlock bios?

Thanks again.

I have the same laptop, and I totally agree with bigchuk00. How did you fix it?

As for vbios, I´ve used it with my 680m, and I´ve boosted my performance (around 8100pts in 3d mark11 and 5400 in firestrike), but in my opinion it has happened because the 680m stock clocks are really low, but it doesn´t happen with the 880m, that seems to be a overclocked card from stock, but if temperatures are low, you can use a mod vbios in order not to have throttling, but only if the temperatures aren´t high, however the temperature stock is usually high for this cards.
