Clevo P751DM2-G RTX3080 upgrade

[IllusiveMan]

Hello community, 

 

Here is the long story short, again, the GPU upgrade story.

Since beginning I went from GTX1060 to GTX1080 with the heatsink upgrade and lapping process, which helps temps a lot even with crap thermal paste.

Now it was time for the final GPU upgrade, initially thought for RTX2080 but eventually got the RTX3080 as it's almost the top possible upgrade (maybe with GA102 chip replacement but it's way too expensive already).

For the BIOS I had taken some of Dsanke RTX version and updated the subsystem ID to match the x170km for proper driver install and realtek audio driver (but still missing the soundblaster app, can't find it anywhere and my old hdd is still waiting for data extraction).

And the heatsink, could not get at proper price the modded ones from taobao or that 1688 so I took the P751TM1 RTX version and the work began.

First, drill the heatsink for the two 22 coils and third one marked these with blue, 3 holes for the screws (forgot about ~2mm core displacement) and added metal the 4th screw marked with red:

 

Next is adding metal for memory displacement and some for VRMs:

 

Next was the process of soldering, so I had some drops of SD-628T which is a must if soldering to this kind of aluminium heatsink:

eventually had to replace top part with copper as aluminium did not want to solder at all.

 

As of thermal pads, had to use thermal gum for top iductors and memory since the pads would be like 0.5mm thik and didn't had any of these:

 

The screws and springs are custom, longer ones from other laptop model: 

 

The process took like 2 weeks of hard work and measurements, including lapping process.

Temps keep good, ~45C in 22C room temp under normal load, as for high load, ~65C with ~120W on GPU and ~45W 8086K CPU.

 

Maybe this overview helps anyone in case of upgrade to rtx30xx seriess.

 

As it remains, a way to fool the driver for GSync (screen ROM edit and maybe other edits) but the 60HZ screen is not worth for now.
