Hi I also use Asus GPU Tweak. I am not 100% sure about this but I belive MSI afterburner does not support voltage control on our 980m...or at least I never been able to use it. Contine with GPU tweak, the latest version work fine for me

And about the temperatures...that probably depends on how fortunate you are with your GPU. Mine gets only sround 5°C higher with overclock to 1300 Mhz core / 5400 Mhz mem. And I sincerly don't know how much further I can go since I didn't try 'cause I don't need to right now. One thing I would control is if the metal plates fit well on the CPU/GPU since I find it strange that you have temp problems even after repasting.

I thought so. There are people with really bad temps (me included) and there are people with awesome temps. I read the default voltage is kinda dependent on the ASIC score? Mine is beyond bad...

Before repasting I got nearly to 90°C under heavy gaming load, after repasting the 980m is significantly colder (~mid 70s under heavy load), same as the CPU now after repasting, though that are temps people got before repasting (GPU though, not CPU).

The heatsinks sit perfectly, they press uniformly and firmly onto the chips!

The default OC vBios voltage is significatly higher what GPU Tweak reports as default voltage now with standard vBios. Even with default vBios voltage and clocks, I cannot game for too long (for example demanding titles like Witcher 3 or Evil Within) before I get a "grey screen" and I need to reboot.

GTX980 has 180W

I did get some data jumbled up, though it's 165W, not 180W. Apparently the notebook pendant should be lower than 165W, whatever that means. Maybe chip selection for lower voltages? Maybe a lower power target?

Prema, is it possible to change the voltage to default, i.e. leave it untouched? Even though I repasted, the GPU gets a bit too hot for my liking with the new vBios so I'd just like to see how far I can go with standard voltage until I really need the additional performance. Also, I got weird behaviour: E.g. when minimizing Witcher 3 und bringing it back up again, fps was locked to 30 and the GPU wouldn't clock higher then ~670 until a reboot.

Also a question to everybody: Did you guys get voltage control working with Afterburner? I didn't, so I had to use Asus GPU Tweak, which is an abomination. I'd really like to stay with Afterburner...

Imho that is a total overkill! You will need big PSUs and plenty of cooling to tame that beast!

eGPUs can combine a "thin" Laptop with an external GPU, that you can easily switch and upgrade.

That desktop GTX980 in a Laptop is in the new watercooled Laptop from ASUS.

I don't think it's that overkill! It has a TDP rating of around 130W versus the 980m with 100W. Depending on the laptop and paste job, the 980m has plenty of headroom left. And when repasting my G751JY it was evident that in terms of cooler size, there's also still plenty of headroom left. But well, guess they will never give us more than we need.
