Presenting the All-New Intel 10th Gen MSI "GS66"!

I'll add firestrike scores over the weekend.

 

What are the scores before and after? And can you take a screenshot of hwinfo64 showing gpu power while running a gpu load like unigene heaven?

 

Reported GPU power is still 80W average. I didn't completely short the shunt like you did so it's not going to show really low values(10W for example). The wattage it's running now is probably 92-94W since the tolerance on the resistors is 5%.

12*0.0333333333/(1/(1/0.005+1/(1.00*0.03)))= 93.33

12*0.0333333333/(1/(1/0.005+1/(1.05*0.03)))=92.70

12*0.0333333333/(1/(1/0.005+1/(0.95*0.03)))=94.04

 

Here are Timespy scores with default clocks before and after the mod.

 

Here are Firestrike scores before and after mod. The one after the mod also has +147mhz on the core and +1002mhz on the memory.

 

Thats a good impovement, though i've seen 2070 super Max-q machines with higher scores. How are the temps though? And what scores can you get with an overclock?

 

The ones you are referring to probably have max-q dynamic boost and advanced optimus. The GS66 doesn't have this feature, unfortunately. When compared with other RTX 2070 Super Max-Q 90W gpus without dynamic boost the scores are comparable or slightly better.

 

Temps are fine. With Thermalright TFX on the GPU and coolerboost on my temps don't exceed 65C with an ambient room temp of 26.6C(80F) and the GPU getting 92-93W of power.

 

Just wanted to follow up but based on the picture of the board for the GS66, do you think it can handle 95-100W on the GPU without prematurely burning out the VRMs or Mosfets?

If you think it's fine I'll probably solder on the 0.022 ohm resistors, putting the power limits somewhere around 98-99W.

 

With proper cooling it can handle 120w.

 

Ah, that's great to hear. In that case, I think I will go ahead and solder on the 0.022 mohm resistors when they come on Thursday. I'll update the thread with benchmarks once I do. Thanks seanwee!

 

These are benchmarks for the shunt modded GS66 2070 Super Max-Q. I used these 0.020 ohm resistors from Panasonic, bringing the power limit to 98-100W.

Also overclocked the GPU, +147 core and +1251 memory.

This overclock is stable and without artifacts. Ran several rounds of Timespy, Firestrike, and Unigine Heaven benchmarks. Also played Modern Warfare as well as Fortnite and gameplay was stable with no crashes or artifacts.

 

Now thats more in line with the performance im expecting. How are temps?

 

Temps are great. Running Unigine Heaven Benchmark for 15minutes with Coolerboost on my temps are under 65C with an ambient room temp of 24C(76F). My GPU is pasted with Thermalright TFX and the vrms,mosfets,nand are pasted with K5 pro.

 

Thats really chilly considering the power boost. The upgraded cooling system of the GS66 is pretty capable.

And i see you're copying my signature, even the links still redirect to my benchmark scores

 

Woops lolz. Thanks for pointing that out. I didn't realize those scores were linked. XD

I hope it's alright if I copy your formatting for the sig.

 

Sure, no worries

 

I was actually kind of curious how do you determine these values? Like what kind of math and formulas are involved that leads you to these conclusions?

 

The chips used for the VRMs can handle up to 50A each, but that is while dissipating around 12-14W each, if you go for a more realistic 30A per VRM, and as there are 4 present, then you have 30*4 = 120A, since the core runs around the 1V mark, thats 120W being delivered to the core and each VRM will be only dissipating around 4-5W each.

 

Thanks for the explanation senso, greatly appreciated. Just wanted to confirm, but were these details about the VRMs being able to handle 50amps verified at some point in this thread? I think it was verified for the GS75 and GS65, but I don't remember anyone here verifying it for the GS66? My picture doesn't show the names on these parts properly which is why I'm asking.

 

Its a specification of the chip, you can read the datasheet:
https://www.onsemi.com/pub/Collateral/NCP303150-D.PDF

The VRM can deliver 50A, they have temperature protections, so they shouldn't just catch fire if abused, but they are over their sweet spot of efficiency, so although they can do 50A, its not wise to push them that hard, because your heatsink wont be able to keep them cool at lets say 12W each VRM, times 4, thats 50W on the VRMs alone, thats more than half the power that the stock VBIOS allows the GPU core to use, and the GPU core has 3 heatpipes over it, so as you can see, removing 50W from those tiny chips wont happen with the heatsink that they have.

Doing some reverse math:
Stock VBIOS allows for 80W, divided by 4 thats 20W per VRM, more or less 20A due to the core using around 1V, at 20A(check page 7 of the datasheet) each VRM is dissipating 2-3W, a pretty low value, at 30A they are just around the 3-4W range, thats just 1W extra per VRM, they wont heat all that much, nor are they stressed at all doing that.
So at 30A per VRM you have 120W to the core, even allowing a bit more, say 35A per VRM for a total of 140W to the core the VRM's should run all that much hotter, because 35A is around 5W from each chip, and games wont put your GPU at 100% for hours, nor does the GPU always uses the same power, depends on what is going on the scene(of the game), I would aim for around 120-140W and then play with the curve editor to find a nice OC that still runs cool(in the 80ºC ballpark).

 

that makes more sense!!!!! caus im doing almost 21k on 80w OC

 

I love what u did a bit much for most bt sure shows what its capable off if we can ever find a darn vbios that gets us there!!!

 

I just wanted to ask. I'm still using these resistors that can handle 1W of heat. I was wondering if these are still okay especially if I'm going for 120W power draw on the GPU.

https://www.digikey.com/product-det...components/ERJ-8BWFR010V/P.010AUCT-ND/1711682

I'm still learning things as I go along, so I just wanted to make sure.

 

I'll be posting benchmarks soon with 120W power limit. Getting the 0.01 ohm resistors in today and will be soldering them on. I should be hitting 9000+ Timespy graphics and 24000+ Firestrike. Should be quite interesting. XD

The GPU has pretty great cooling in the GS66. Super stoked to have this type of performance in this thin chassis.

 

While I do applaud your efforts, this is going into "unsafe" territory. Especially considering that the GS66 doesnt have a dedicated heatpipe over the vrms, only a thin heatspreader.

Keep an eye on thermals and vrm thermal throttling (ie, gpu clocks dipping for no reason)

 

Thanks for the warning seanwee. I'll carefully monitor the situation.

Based on what senso said and looking at the spec sheets it seems the increase would only mean 4W generated per vrm, so 16W of heat generated in total across all 4 vrms. Is it that much riskier? I just don't have a good sense of what temperatures 16W of power can create.

I don't plan on going above 120W. Right now I'm at 100W and that's roughly 3W of heat generated per VRM based on the spec sheet, and I am not having any issues at all. Clock speeds are stable as far as I can see when running benchmarks and gaming.

When you say dips, how steep of a dip are you talking about?

If you feel its necessary I can also attach some pipes conducting heat to the actual heatpipes leading out to the fins. If you still feel that it's still unsafe with the additional pipes to help aid in cooling then I can just stop at 100W entirely and not pursue it further.

 

I was thinking of doing something like this to provide more cooling to the vrms and mosfets. Gelic GC Extreme underneath the heatpipes wiith thermal glue around the ends to hold it down. Kapton tape there is just me being abundantly cautious of it shifting around. Didn't want to use too much thermal glue since I want it to be easily removed and cleaned.

 

That would work wonders for the vrm cooling.

It'll just be a bit messy with all the paste.

 

Its a bit messy but I'm fine with it. With the extra heatpipes though do you think this is back in the "safe" territory?

 

It wont hit 105C for sure so safe enough.

 

anyone have any documented cases bout hinge issues on the gs66? i saw one but thats bout it

 

My unit has been running perfectly for the past 5 months. I have had it since release day in April. No issues with hinges or the bezels peeling outwards. I think the single Reddit post on the GS66 hinge issue is the only such case mentioned online so far.

 

Just for those curious, my shunt mod is still at 98-99W using the 0.020 ohm resistors. My 0.010 ohm resistors haven't come in yet, so I've just been learning to play around with the voltage frequency curve a bit more to fine-tune the overclock. Here's my currect voltage/frequency curve

https://imgur.com/a/Y3MBHEc

+1100Mhz on memory. My Timespy Graphics score is now at 8745. This is again at 98-99W.

https://www.3dmark.com/newsearch#advanced?test=spy P&cpuId=&gpuId=1325&gpuCount=0&deviceType=ALL&memoryChannels=0&country=&scoreType=graphicsScore&hofMode=false&showInvalidResults=false&freeParams=

Right now I have the highest Timespy graphics score out of all the RTX 2070 Super Max-Q benchmarks put out there. Still not done fine tuning it yet. These are just preliminary results.

 

Nice

 

Update with the new resistors. I added 0.01ohm resistors with 0.022ohm resistors in parallel to the original shunt resistors 0.005. Wattage should be 138W, but because of tolerances and added resistance from the solder I would put the total wattage somewhere between 130-135W. The voltage/frequency curve isn't really optimally tuned. This is more of a quick and dirty result. Running Unigine Heaven benchmark my temps didn't go above 72C with 24C ambient temps and elevated with these small standoffs.

Also for daily use, I have more reasonable settings with undervolted profiles at 0.85mV, 0.875mV, 0.9mV, 0.95mV, which I have not included here. The highest settings really are only used when it's necessary for benchmarking .

Great results. However, i do think you're overestimating the gpu power draw by a good 10-15w. If you check how your current performance lines up with overclocked 115w 2070 supers its pretty much the same. Dont forget to factor in efficiency losses as the power draw increases.

 

Yeah, I also think the power estimates aren't entirely accurate either. Those were just made with the simple power law and Ohm's law. The performance definitely isn't in line with what we would expect from a 130-135W RTX 2070 Super. Also, my overclock isn't exactly optimized here. With more tuning, I would put the score somewhere at 9200-9300.

I have also seen some overclocked Mech 15 G3 with the RTX 2070 Super 150W and they get Timespy graphic scores in the 9200-9500 range. So the power is probably somewhere between 115-125W for a more realistic estimate.

 

The Mech 15 only has 115w 2070 super.

 

With Eluktroboost it hits 150W. Its shunt modded out of the factory. Here's a video that Bob did that demonstrates this.

 

Firestrike graphics: 23624
Firestrike overall: 19924
Highest firestrike graphics score, 3rd highest overall score
Here is a link to the result: https://www.3dmark.com/fs/23405548
Here is a link to the raknings: https://www.3dmark.com/newsearch#ad...de=false&showInvalidResults=false&freeParams=

 

Something interesting to note is that my Firestrike scores tend to be higher in MSHybrid graphics mode(~23500+ Firestrike graphics) than in Discrete graphics mode(~22000 Firestrike graphics). Not really sure why this is the case but just something to note.

 

That's impressive....i still dont have the balls to do it...but im mighty impressed

 

Also if you guys want better airflow for your GS66, or for that matter any laptop with low clearance on the bottom, you can use Sugru to shape feet with higher clearance to use.

https://sugru.com/

There are DIY recipes, but I have not personally tried those. Here are some pics of the feet I made for my GS66. It gives me about 1cm of clearance on the bottom compared to the 0.4-0.5mm(back feet) and 0.3-0.4mm(front feet) clearance it had before.

 

Just leaving pictures of the VRMs and Mosfets for future reference.

 

Officially broke 20000+ overall score and 24000+ graphics score in Firestrike. Highest score on the leaderboards for the RTX 2070 Super Max-Q.

@werdmonkey4321 just out of curiosity, what is the red stuff you used to isolate the GPU for the liquid metal?

 

Its just liquid electrical tape. I used Star Brite liquid electrical tape I got from Homedepot.

https://www.homedepot.com/p/Star-Brite-4-oz-Liquid-Electrical-Tape-Red-084105N/206513457

I used it to protect the capacitors around the GPU die. I also used a barrier made from K5 pro to seal up the area around the GPU. I may have gotten a bit overzealous with my use of the K5 pro. XD

 

Lol Super high profile with all the white stuff, awesome.

 

I now have the highest Time Spy graphics and overall score in the world for the RTX 2070 Super Max-Q. There is still a lot of room left to overclock the card, but I think I can just leave it here now that I have the highest score worldwide for both Fire Strike and Time Spy. I'll leave a little bit of room to play around with later on when I get the overclocking itch.
