Clevo P775 power limit?

[tway]

I don't know how old these are but when I take my heatsink off my thermal pads have noticeable physical indents from the components they're contacting (similar to yours in the bottom left). Maybe you have the same issue as DoenerBoy where yours have minimal/no proper contact due to not being thick enough. I could be wrong or not seeing properly from the pics but either way replacing them will be much cheaper than any actual hardware so may as well try imo. Also is that liquid metal on your die?

@tway First of all, congratulations on fixing your GPU! As for my heatpads, it's probably not a bad idea to replace them. Also I need to check those screenshots again closely, if all relevant components are covered. As for the indentations, sure, flipping the pads should solve that. It might be liquid metal, has a golden colour. Don't worry, I used a modest amount and there is plenty of insulation around the die, so that won't cause a short circuit.

 

Edit: Did some research on liquid metal and what they mean is Gallium, that has a silvery colour, so no, it's not liquid metal 🙂

 

Now, regarding temps, if Furmark doesn't crash, I left it for about half an hour (-450 core increment):
 

GPU: 80°C

GPU hotspot: 93°C

VRAM temp: 90°C

 

How are your temperatures with the new heatpads?

Yeah it's unfortunate the P775 has these design flaws, but also I find your experience with Eurocom crazy... 

 

I personally never bought from them since they looked like scammers to me, but for the prices they're charging I expect them to fly out a representative to your doorstep as customer support 😂 who do they think they are charging this much? Apple? They are very clearly trying to exploit us, I have talked to so many private sellers with overpriced Clevo parts who point to the Eurocom ebay shop as a justification. And this is their goal all along, they know exactly what they're doing. Best we can do is not buy from them, I don't know how they aren't out of business or anything by now, some of their items have been sitting for over 2-3 years with no sale. 

 

Anyway this is off topic now but hopefully this dissuades people from giving those scalpers any money. It wasn't always like this but as of present that company is doing much more damage to the community than adding anything of value. @Kniben I hope it's just your thermal pad placement that's bad so you don't have to buy a new motherboard, especially from them. I've attached images I found in some threads that I used as references to check thermal pad placement, hopefully these help.

 

 

 

 

 

Last thing about Eurocom from me: In the end it was almost comical to see how they weasled themselves out of doing the right thing. It was not about a big amount of money and I shudder to think what would have happened if I had bought something really expensive from them.

 

Looking at your GPU it is clear that paying attention to the pad thickness and choosing the right pads seems to be quite involved and makes me consider to finally try my thermal putty that I have sitting arround for quite some time now - if only it wasn't so messy.

@1610ftw You asked if somebody could use an E-meter to measure actual power draw from the AC side. Here are the results, mind you (-450 core increment)

Furmark 3840 x 2160: 198 W

prime95 Small FFTs, all 8 cores: 194 W

Both of the above: 322 W

 

The thermal pads I used were stock and I used them since I bought the thing in 2019. I doubt the technicians at XMG did a poor job during assembly, but I noticed one of the thermal pads not covering the inductor at the bottom and that tiny square chip. So perhaps the coil just died. I also don't know if the inductors are staged according to core frequency, meaning not all of them are used, if the core frequency is set to a lower limit. I can achieve stability by reducing the core increment by -450, while tway needed -700. Heck, I don't know how the GPU regulates its power, all I know is, when things get hot, they break or at least degrade over time and I think that has happened with the coil I mentioned. Perhaps the GPU is unsalvageable and I should buy a replacement.
