higher TDP for RTX 2060

I did a shunt mod for mxm 2060, it was great)

[zex4]

Do you have pics ?

Would be very interesting to see...the only thing that I did back then was with pascal bios tweaker but without any success....

Finally! 12K Graphics! RTX 2080 200W +160 Core +250 Mem.

 

Nice job! Im getting 10k with stock bios and no OC at 165W consume .

Desktop 3060ti is the same gpu score with Alienware Graphics Amplifier ( Pcie X8 3.0) and 6700HQ cpu in a 13 R3 .

Thinking about going back 😕 (sadly)

Sure, just add mgtf wire around rs1 and rs2 resistors on back side of the PCB:
 

[zex4]

First what means mgtf wire ? And how much tdp you got after the shunt mod ?

 

 

Ty so much for the pic and info bdw 😇

[zex4]

I just hope that shunt mod makes 2060 faster than the 1080 as example....

It is necessary to reduce the resistance on these resistors. In my case this was done by soldering a thin wire. (mgtf) The TDP approximately doubles, the adjustment is made by adjusting the curve in the MSI AB. 

[zex4]

This is how my 2060 looks like..wanted to show it before I do the shunt mod...it was the quality sample i got from clevo directly

 

But it seems you added some capacitors on empty spots...

 

Hope I don't need to do that aswell...I will not overclock anyways...

 

 

[FTW_260]

@zex4 RS1 and RS2 in the second picture are what you need.
There is no need to make this modification if you are not sure that you will do everything correctly.

After hardware changes, you need to correctly configure the card consumption (voltage curve) in the MSI AB.

[zex4]

Thanks buddy can you send me  a screen from msi ab 😉

[FTW_260]

This makes no sense, the curve in MSI AB is unique for each card.

Finally a proper copper shim mod. 
Took me awhile but at the end it worked out pretty well.

As i see you are using LM on cpu, how did you isolated the heatsink? And how much isolation is on the gpu chip from the sides? Usually we dont LM gpu-s cuz if its not contacting with the heatsink you can overheat the sides of the  gpu , and kill it.

[MiRaGe]

LM, when applied correctly tends to stay in place. No need for isolations etc. Besides, I use custom heatsink and the contact area fits perfectly on the cpu and gpu.

I had foam dam before, but took it off.

Yesterday I accidentally found this cool custom heat sink for the good old p775 on taobao . It has two integrated vapor chambers for the CPU and GPU, as well as larger grill areas where the fans are installed. (it seems that the rear decorative panel on the case needs to be removed to install this monster)

It looks massive, heavy, and powerful. 
There is also the option of separate gpu and cpu heatsink, also with vapor chambers.
The price is about 150 dollars.

Pretty sure it can handle 400W+ heat with custom fans.

 

I was intrigued by this heatsink and I dug up some more info about this as the seller is quite interesting.

He claims that this version is good for about 165W of heat dissipation for the CPU with no real world limit to the GPU. 

 

There are a few funny things coming out of the translator like that this is a heatsink that is only suited for freaks with strong hands but there is also a lot of useful info and I managed to dig up a document with a number of pics, here is the monster heatsink mounted in the P775:

 

 

 

And here is the new butt Alienware-style, looks like it has to be riveted to the old bottom cover:

 

 

 

mounted, probably around 2.5 to 3cm deeper:

 

 

Looks as if one would need a flashlight to find the connectors on the back :D

He also has some special fans that he highly recommends for the bigger heatsink as throughput from the shoddy stock fans won't be enough:

 

 

There is also a less extreme heatsink that would fit in the existing case and from what it looks like without any cutting but he could also make the heatpipes all go through which I think would be preferable if one often has CPU-heavy workloads:

 

 

Feeling a bit tempted now to get one of those heatsinks and a pair of those fans 😄

If you decide to order it, let’s make a combined order as we both are located in Germany😊

I am interested in this too👍🏻

Will let you know but it is indeed a bit tricky to contact that guy as he is only on taobao 🙂

2. This is just my opinion, but I am happy with the way I have it:

• Updated to latest Clevo BIOS;
• Unlocked it;
• Updated CPU microcode, RAID modules, Ethernet module, to the latest revisions;
• Updated the Intel Managment Engine to latest revision and also edited it a little to allow Base clock or BCLK overclocking in the BIOS (Can achieve interesting RAM OC results and etc)
• Added support for RTX 30 series GPU's

Some people say that Prema is the best but I have no idea because I have never tried it and I am not sure if someone even has it for this laptop specifically anymore. Any requests for them are apparently deleted or something here so yeah. If you have a hardware flasher and can make a dump of your BIOS I can help you with all these modifications but I have never flashed any of my modified BIOS binaries with software so I have 0 guarantees whatsoever that it will work for you in that case. And I just remembered there is some Dsanke version out there but I have never tried that aswell. I just updated to latest clevo BIOS and proceeded to do the rest as I put it before. I might have done something more that I just can't remember but thats the essentials basically.

Hi there! Just got my hands on a P775TM (late to the party i know). I own a flasher and also have a dump of my bios would you be willing to help me out? Thanks!

Hi,

I hope its fine to post and follow-up on this thread about my Eurocom Sky x7c, based on Clevo P775TM1-G. It covers similar issues about tackling thermalling with this chassis coupled with an i9-9900K and RTX 2080 (Mobile) as reported initially by @MiRaGe. In my case the CPU was delided and a vacuum chamber was used in place of the IHS, and liquid metal was applied to both CPU and GPU.  The last application is 2 years old, the copper vacuum chamber, unified cooler, CPU and GPU surfaces were all LM treated a coupe prior to last application. 

 

All four slots are used (dual channel), 64Gb total, with 4 x 16Gb Kingston Technology HyperX Impact 2666MHz DDR4 CL15 .  This could be optimised as needed.

 

After a fresh install of Windows 11 24H2 4Bit Pro, optimized with Atlas-OS 0.41, I am reconsidering the hardware and software configurations and the high cpu and gpu temperatures.

I ditched Intel XPU and started to learn to use Throttlestop 9.6 (TS 9.6) to mitigate thermaling and power issues when using my system under heavy CPU and GPU load. 

An initial TS 9.6 setting gave a package power of 138.4W CPU Core offset voltage -110mV, CPU Cache offset Voltage of -80mV, reaching Thermal EDP and L1 Limits on CPU with TS 9. bench.
With this initial TS 9.6 undervolted Settings, Time Spy score was 10 039 (Graphics 10 075 (average temp 69c), CPU 9842 (average temp 98c)), with max fan speed, on a cooling tray and bottom covered removed - ambient temp ~23c near the air intake.  Test results: https://www.3dmark.com/3dm/120452444

 

My concerns are that under heavy load (virtual reality applications) temperatures are maxing out (TjMax, GPU high temp):
CPU cores temp ranges 85-99c, PCH temp can go above 5c, and GPU temp 87c, temp-hotspot 100-103c, which is seems too high, are sustained during the whole session of 2-3h nonstop, sometimes several times a day.

I would rather lower temps and power limit for a stead and cooer operation reather than max perfrmance with thermal and power throttling, which also risk to age my trusty mobile VR sstem.

 

Questions to help me getting started:
1)  Are the temperatures above reasonable to run run long and sustained heavy load sessions?
Is the GPU T-hotspot above min 100c reasonable?

Any sugestions of ballpark values for efficient undervoting with TS 9.6 and also power limiting the gpu with Afterburner?

 

2) In an old thread on NotebookReview I was discussing the i9-9900 cpu and PCH high temperature with @jc_denton and others. He was able to lower the temperature by 5-7c with 4mm thermal pad on a p870.  
It is not clear to me where the PCH chip is (under the mouse pad?) and how it can be accessed and how to carry out a modification, since here is no heat spreader for the PCH in the P775TM1. Did someone do this modification and has a picture to share?

 

3) The TS 9.6 bench test returns these 16 Max core temperatures (in C): 95, 95, 100, 100, 98, 98, 99, 99, 99, 99, 98, 98, 96, 96, 89, 89.  Most are within 5c of each other but the last two of the 16 cores are 11c from max core/TJmax temp.  

a) Is it a sign that the unified cooler is warped or thermal pad contacts are not optimal?

 

b) The i9-9900k cpu was not sanded /lapped, similarly would it be worth removing 0.3-0.4mm to improve thermal heat transfer and contacts?

-or-

c) a fresh LM and new pads are required?

 

4) I was provided with Bios and EC fie to update my systems from Eurocom four years ago. The software upgrade failed and couldn't be applied.
Would Bios updates would be warranted and hep better manage this system?

 

The current system:
Intel  (R)  Core(TM) i9-9900K CPU @ 3.6GHz
ME FW Version 11.8.5.3606

MB Series:     Sky X7C
Bios Version:  1.07.2REU4
KBC/EC Firmware Revision: 1.0.16

VGA Card:  NV GeForce RTX 2080
VBIOS Revision: 90.04.3B.00.7A
VBIOS Build Date: 12/04/18

 

Thank you for your help and suggestions to get me started.
