Hello. I managed to bend the heatpipe but didn't glue it yet because I need to do some chassis mods. I also made a new post about the possibility to edit the 4080's vBios?
-
I'm a little bit late. Actually, the vBIOS is uploaded on techpowerup. It's the "X-Vsion 4080 12GB".

Hello again. I have an RTX 4080 MXM card. My laptop is a Clevo P570WM that can handle max to 115W of heat. The MXM card can use up to 150W. On GPU-Z it says max 150W too. The max temperature before thermal throttling is 83C which is annoying. I just wanted to know where I can find the value (inside the file) for the TARGET LIMIT of the TDP and the MAX THERMAL LIMIT in celsius. I want to set the max target limit to 115W and the max thermal limit to 87C. I can't flash any random 4080 laptop VBIOS because my card has MICRON VRAM chips. It means, every VBIOS available on the net only use Hynix/Samsung combo, no Micron available. I know unsigned vBIOS without the correct checksum won't work. I do own a CH314A for flashing tho. I just want to know if someone knows how to VBIOS mod the TDP limits and thermal limits. I know someone edited the vBIOS of an RTX 3060 Ti Ampère but he didn't explain how sadly... So if any of you knows, please write it down. Thanks.

No space for one. I already use two GPUs in one system. I can just add one extra heatpipe, I tried to bend one, it's ugly but still manages to conduct the heat (hot water test). I bought 2 more heat pipes because mine modded one can't fit since I did something wrong in the first angle.
-
Do you see my heatsink? There's a place to add one heat pipe, I need to curve them like the first and second heat pipes. EDIT: Bruh I bought brass heat pipe... (Copper and some zinc)
-
Yes this one too. He used a rubber toy
-
I can't send a picture because of the limit but I have a place to add a 3rd heat pipe on the copper plate of the GPU die. I also have some margin to glue the heat pipe on the heatsink. I bought 3 18cm heatpipes because it's an enough length. I bought some thermal glue that works between -60C to 250C. I did see a video on how to bend a heat pipe with bare hands, but don't you guys have something safer and can be done for free?
-
I still haven't tried the 4070 (115W) on the Clevo P570WM but on my Dell Precision M6700 the temps were so high and the memory temps reached over 115C Do you guys think I should add a 4th heatpipe? I have 3 heat pipes. 2 for GPU and one for top VRAM/VRM
-
No all the RTX 4000 don't support eDP. 4070,4080 NO EDP!!! I get 255FPS on FurMark at 1080p with 120W limit. Still hits the thermal throttling at the end of the test but not by too much (95-100W)
-
And why mine has big gaps? If they all touch?
-
Eurocom told me to use a copper shim lol
-
I don't understand the video because I can't watch it right now. I don't understand what gap do you mean? Between the GPU die and the copper heatsink?
-
That's how I did it
-
I can lower to 110W using MSI Afterburner but... It also decreases the thermal limit. From 83C to 75C. Yes it thermal throttles at 75C at 110W... Funny

I don't know. My PTM 7950 is a 20mm thick one instead of the 25mm one. I saw some tests with liquid metal and there are no gains.
