Graphics Card upgrade for M6800 ?

and for those who are curious these are the thermal pads I bought and seem to be working fine ......https://www.amazon.com/gp/product/B074K55CWF/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 ........

 

So my 980M ended up not being stable while undervolted to 0.95V. Altho Metro Last Light and FireStrike on loop were stable when I was running them for few hours, using multiple monitors (3x FHD) ended up crashing drivers once per hour. Bumping up voltage to 0.962 made it all go away.

I wanted to keep that 0.95 voltage due to overall noise reduction and system temperatures so I've ended up limiting turbo boost to base clock of 1038MHz. If I want I can use MSI Aferburner to bump up the core clock, but with 0.95V max stabile clock is 1100MHz, after that, driver crashes start to happen.

I've lost some performance I know, but temperatures are now under 70, all the time, which is not that much of an issue, but the fan noise was. Now I'm back to levels of noise i had with K4100M when it was overclocked to 940MHz.

I'm finally where I want to be with the noise levels and will stop messing around now with vBioses

 

And apropos of nothing ..... Bob Mook had a frame and alignment shop near where I grew up ......I always thought it sounded funny so I adopted it for online use------ I never met the man.

 

Does anyone know what safe temps are for the P5000? In Windows I never get above 70 degrees. However under Linux I get about 15% better performance ....but .....also spotted the card recently at 77 degrees ...............

 

I think that the pads you installed are not helping to keep the temps down.I am using Arctic ones and are helping perfectly with temps.

 

What thermal paste are you using?.What about the heatsink?
Could you post a picture?

 

Modern NVIDIA mobile chips won’t throttle until they hit around 87. 70’s is totally safe. The temperature range in mine was about the same, with the fan running 100% it would stay comfortably below 80.

 

I finally got my 980m installed. This one actually has 8GB vram. I was running into some throttling issues at first, but not as bad as the previous card that I used. Following darkydark's post about modifying his 980m, I undervolted mine to 0.981 volts maximum, and eliminated boost clock entirely. Before it was always using its boost clock (more than 1100mhz) but the whole system was overheating. Now with the GPU capped at the 1038mhz base, I don't see too much of a drop in performance but I do see a big difference in temperatures. The GPU maintains 1038mhz indefinitely, and the CPU clock doesn't change throughout gaming either. GPU stays at or below 70 degrees C.

This thing is pretty good considering the 980m is nearly 5 years old!

 

I did some checking and there's not that much dropofff from the P 5000 and the 980m .....I was also quite impressed by DarkyDarks methodology. It sounds to me like you got a better deal for a better card this time around.

 

So far so good! I got seamless switching between hybrid and dGPU-only mode working in Fedora with just an extra script that runs at boot time. That was *way* easier than trying to get the Dell 7730 or Thinkpad P72 with the P4200 working with Linux the same way...

Switching with Windows is actually more clunky, since every time I switch between hybrid or dGPU-only mode I have to go in device manager and choose the correct driver for the 980m (and sometimes reboot)
