*** The Official 2020 MSI GS66 Stealth Owners and Discussions Lounge ***

Leaving this here fixed the name

 

Does anyone happend to have flashed a 90 watt bios for the RTX 2070 Super Max-Q. I'm looking to do the same but so far no one has uploaded a 90 watt bios anywhere yet, including techpowerup.

 

Shouldn't this be "2020" instead of "2019" and be in the "MSI Reviews and Owners' Lounge"?

 

I'm not sure if people here are interested but I have a post up on Reddit that does fairly comprehensive thermal benchmarks for the GS66 10SFS-037. This is the model with i7-10750H, RTX 2070 Super Max-Q, 32gb ddr4 2666 ram.

Also, take your time when doing repastes and adjusting tension on the heatsink. This is more of a cautionary tale but I ended up getting a 4C reduction in temps. I was careless in my previous repaste and forgot that I shouldn't release tension on the heatsinks, rather I should slowly increase tension to correct for core temp differerntials.

There seems to be mixed information regarding whether or not setting the core voltage offset greater than the cache voltage offset provides any benefits in terms of package draw. The answer to that is that it depends on the workload, but it does produce a significant effect when the workload can take advantage of the extra offset. My experiments are contained in the edits of this Reddit post here

https://www.reddit.com/r/MSILaptops/comments/h7vru3/undervolting_setting_core_voltage_offset_higher/

In particular, I set the Core voltage offset(-219.7 mV) to be at 2 times the cache voltage offset(-110.4 mV), as suggested by /u/Sultanxda, and it produces a significant reduction in package and core power draw. Running Realbench for 15 minutes in each individual experiment I ended up seeing a 5-6 C drop in package power draw.

In Prime95 with AVX/AVX2 off however I did not see any effect in power draw there. My conjecture is that the extra offsets greatly benefits situations where AVX instructions are used but for workloads that don't use AVX instructions the Core and Cache offsets are tied, so the lower of the two values takes effect instead.

My conjecture also seems to be verified by other users as well. Please see comments here by unclewebb and Krzyslaw in reply to my comment

I got a non-Super RTX 2070 mostly because I didn't want to pay few hundred extra for less than 10 FPS increase in the games I play. I threw in the 1TB SSD from my GS65 to this one and sold it to my brother so I will be part of this crew for now. Default thermals were bad until unlocking overclocking (undervolting) in which now everything is quieter than the GS65 and has the battery life to last me an entire plane trip to Europe.

 

I thought people might be interested in temperature differences between using Kryonaut and liquid metal.

I ended up repasting with liquid metal on the CPU in my GS66. I decided to use Thermalright liquid metal Silver King instead of Conductonaut, since the latter would take a week before it would arrive here. Mr.Fox also said the Thermalright liquid metal had the same performance as Conductonaut so no real losses by using it instead.

Also I tried the foam dam, but it ended up giving really high temps because of the metal shroud that surrounds the die in the 10th gen CPUs. This shroud is also present in the Asus Zephyrus S15, which includes liquid metal out of the factory, so the inclusion of the metal shroud is an Intel addition I think? I'm guessing they included it to prevent thermal paste/liquid metal runoff. I instead opted to create a barrier by putting a thermal paste boundary on top of the metal shroud. All of these details are mentioned in my Reddit post below. Here is my post with benchmarks.

Overall I noticed an 8-10C improvement in max core temps by going from kryonaut to Thermalright liquid metal. Core differentials also improved from 10C to 5C in between cores.

 

Here are some comparisons of thermals when using Thermalright Liquid Metal Silver King versus Kryonaut on the GPU.

At stock settings, there are no observable improvements in thermals. Maybe after flashing a higher wattage bios the differences can be better appreciated, but with the 80 watts RTX 2070 Super Max-Q there is no difference in temps.

 

pretty sure at 90w ull only see like 2 -3 degrees more

 

I just wanted to ask but for the RTX 2070 Super Max-Q will there be any versions with power limits higher than 90 watts by chance?
