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

I know the GE66 has it, but I didn’t see it at all in the GS66.

im not sure we see it somewhere i thik its just there

 

If it’s available, there’s an option in the driver to turn it on or off. This was t the case with the GS66. I tried all available drivers and it never showed up.
On my GS65, it was accidentally left in one of the drivers and then disappeared with the next driver.

of course i could be wrong

Yeah i reckon ut has something to do with the i9 pulling tis weight around if i disable 2 cores it doesnt do it, funny thing is it doesnt consume the 230w from the power brick but still does this weird thing where the watts start tod rop during aida/unigen heaven combined stress testing

 

Were u power throttling?

 

If i do the imon mod, TS wont be able to read Power properly and thus wont control PL1 correctly i believe...i have it set to 50w and 85w in TS

 

You mentioned liquid metal repaste on this laptop, how much did it bring your temps down?

 

Unsure because it came from HIDevolution with it installed.
Based on previous laptops, probably 10c on cpu and gpu. That’s my ballpark.

with the 8 core?

 

I’m just guessing the drop. I’ve seen ~10c on the CPU and GPU when going from stock paste to liquid metal.
With the 8 core, I was always thermal throttling at 95c at 4.3-4.4ghz.

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.

 

Thanks @JRey . I was also considering the XPG SX8200 Pro 2TB SSD ( link). Will that fit in the the MSI? One user review stated "It's a 2 sided PCB with components soldered on both sides. Could not be installed into applications that use a low form factor M.2 NVME female socket due to clearance issues caused by the stuff soldered on the bottom. "

 

I've installed an Inland Premium 2tb NVME drive with NAND on both side successfully in the GS66. There is more than enough clearance. Had room to add thermal pads underneath too.

 

@werdmonkey4321 Superbly helpful, thank you!

 

i have 2 cores that hit around there every other core is under 90 freaking weird...im on lm from hid also, also this is with aida and unigen combined stress test.......cinbench, gaming, even aida on its own doesnt push it as far

 

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.

Yup, they reused the same 2019 panel. This is mine:

http://www.panelook.com/LQ156M1JW03_SHARP_15.6_LCM_overview_37935.html

I'll be honest, it's terrible. The peak brightness is far too dim and the colors are not vibrant at all, it feels like there is always a 10% shade of yellow on everything even after calibration. Really lets this great laptop down.

I now want to change my panel but I'm having difficulity finding one due to the Hz rate. Do you have a model number for the AUO panel and will it be compatible?

EDIT: Found it.

Should this work fine with my 240hz gs66?

 

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 watt 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.

 

wrong thread

 

It should work fine as the monitor is connected by eDP so the controller is embedded in the LCD unit. It is hold in place by sticker tape so fit should be fine.

Drivers exist for Window so brightness should be adjusted OK.

Are you going ahead purchasing the B156HAN12.0? I might do it too.

 

I have both units at hand a gs65 240hz and gs66 300hz and aside from the brghtness dont see that much of a difference, bot i calibrated with my xrite

 

Good feedback thanks!

How much brighter you find the AUO panel? Significantly more? A bit more? Maybe can you make a picture of both together at full brightness?

Can you measure them with your xrite?

 

I belive i can measure them....will do when i get home

 

I received the gs66 (10980HK) 2 days ago and haven't had much time with it so far, but did get to undervolt and run some benchmark.
My multi-core behavior seems appropriate (runs as expected, hitting around 111W in PL1 and then going down to the default 65W PL2, maintaining the 8 core 44 multiplier) hitting ~4200 in Cinebench r20.

However, when it comes to single core, it only uses 25-30W and only hits 4.7-4.8GHz (instead of the default 5.3, or even 5.1 for 2 cores), and I can't figure out why. Temperatures are not an issue (with Auto, the fan is barely running and the temp sits ~70C, with coolerboost it sits in the 50s and makes no difference) and XTU reports no throttling of any kind (and says there's only 1 active core as expected, and the load is bouncing back and forth between my two optimal cores). I've tried all the various power settings (Extreme Performance, as well as User on High and Turbo), as well as changing windows power profile to 'Ultimate Performance' and nothing seems to make any difference. Keep in mind that all the while with any of these settings, mutli-core behavior is as expected, hitting and maintaining the 8 core 44x multiplier.

Thoughts? Any ideas why it's only hitting up to 30W even though there's no throttling of any kind? Maybe @JRey as in your review you were hitting the expected.

 

i havent seen anyone ht 5.0ghz yet so this s not uncommon

 

I believe for Ice Lake cpu it will only boost up to that range if thermal velocity boost is active, and this is only the case when power budgets are available and the T_case is below 65C.

 

Without tweaks, I was able to hit 5GHz-5.1GHz at 68c.
With tweaks, I was hitting 5.1GHz-5.3GHz at 70c.

With that said, try downloading Throttlestop and migrate your undervolt to that software. From there, run TS bench at 1024 and single thread and see what happens. Remember to reset XTU to defaults before disabling it (from what I've read, you're supposed to do that)

I had an issue where Cinebench wasn't boosting to 100% speed and TSBench was. If thats the case, try undervolting your core a bit higher but leave cache alone, then try again.

With my GS65, unsyncing Core and Cache led to higher sustained clock speeds and lower temps.

 

did u try unsync on the gs66 8 core?

 

Unfortunately, I did not.

I can try if u want.

 

So since the max frequency I was hitting aligned with the 5-6 core ratio even when a single core was active (as the case for R20 single thread test), I decided to see what would happen if I changed core 1-6 ratio to 5.3 (at which point I thought I recalled some reviewers mentioning that when they received the gs66, all the ratios by default were set to 5.3), and sure enough, the laptop immediately started boosting to 5.3GHz.
Now an R20 single thread run scores 537 vs ~490 earlier, with the clock hitting 5.3GHz and averaging 5.24GHz.
However, I don't consider this a good solution since I don't want 6 cores attempting to run at 5.3GHz, and it messes up the undervolt.

@JRey when you received the laptop, do you recall what the default core ratios were?

 

From all core to single core:
44 > 46 > 48 > 48 > 50 > 50 > 53 > 53

Thanks, that's what mine looked like as well (all defaults). Does seem like with the latest Bios+Firmware it's boosting a bit higher with those default (5GHz, with 4.8GHz avg), but only way I seem to be able to get consistent 5.2-5.3GHz is by raising the ratios so that 1-6 core are all 5.3. But again, that's not worth it, so just going to keep it with those stock ratios and leave some performance on the table. It's not really a hard decision as with those settings the 'Auto' fan profile remains quiet with the temps remaining in the mid 70s)

 

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.

http://forum.notebookreview.com/threads/liquid-metal-and-33-tape.829130/#post-10985882

https://www.amazon.com/Thermal-Perf...ermalright+liquid+metal&qid=1592784282&sr=8-3

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.

https://www.reddit.com/r/MSILaptops/comments/hdhdca/gs66_liquid_metal_versus_kryonaut_thermal/

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.

https://www.reddit.com/r/GamingLaptops/comments/he0ddb/gs66_liquid_metal_vs_kryonaut_on_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.

 

Question, anyone know what the red grainy paste looking thing is on the heatsink? I redid the paste for the GPU and CPU and was wondering if I could just use paste or use some thermal pads for the red paste like thing or just use thermal paste for those? I got some 0.5 and 1.0 mm fujipoly coming tomorrow so wondering if I should just use some noctua nt-h2 or use thermal pads for the red paste replacement. On cpu and gpu I got some thermal grizzly kryonaut on there. Didn't want to do LM just in case as I had some issues with it staining and making the surface rough on the heatsinks before on my gs65.

 

You can use K5 Pro thermal paste or thermal pads to replace the stock red thermal paste.

If you do decide to user thermal pads use ARCTIC thermal pads. The Fujipoly ones were to incompressible, so they cause issues with the heatsink making good contact with the CPU die.

You can look at my post here for sizing info on the particular pads.

https://www.reddit.com/r/MSILaptops/comments/gvnsxj/gs66_thermal_pad_size_guide/

So far this sizing has worked well for myself and many others. I have checked on my unit and these pad sizes make good contact everywhere, but please let me if you find an issue with the fit. I will be doing a repasting in 6 months time, but I can do that ahead of schedule if you notice any issues.

 

Tried fujipoly first and you were right it didn't make a good enough contact. Highs were hitting 95 on 2 cores with the cpu-z stress test and after swapping it to arctic it was 88. This is with -110 UV on the core for both. Really wanted slightly better pads but I guess the 6mkw is working good enough even though I would have liked using the fujipoly 17mkw. Gonna try messing with it more once I get the new 3200 DDR4 memory from newegg tomorrow and I should be done opening up the laptop. Waiting on some skins to arrive next week for the GS66 so hopefully it looks as nice as the youtube video! In case anyone is wondering this is the video that I found from reddit:

 

By the way you can undervolt the core even more. The extra offsets are utilized whenever you do workflows containing AVX instructions. Modern game titles in particular will be able to take advantage of this.

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

 

Just tried increasing the offset some more up to 210 and didn't seem to see a hit in my gaming performance so all good. Honestly this machine is gonna be mainly gaming and photo editing with a small chance of video editing once I get around to learning premiere pro. Lol

 

Quick question - does the laptop have a fast charging feature? Some other laptops in the market can charge 50% in 30 minutes (such as Lenovo Legion 7i), does the GS 66 have this feature? If not how long does it take to charge to the 50% mark? To full charge from 0?

 

Does anyone know if it's possible to have multiple fan curves which are used for different Throttlestop settings?

I'd like to set a really quiet and conservative fan curve for my Gaming throttlestop setting and a more aggresive fan curve for my high performance Throttlestop setting.

 

u try silent option? thats all u really need

 

I'm already using silent option. I noticed recently there is a new firmware update from 6/19 where they made adjustment to the CPU fan table.

When they say new CPU fan table do they mean they changed the trigger temps for the fans in Dragon center or what?

 

Just donated to Svet on MSI-Forums. He is looking into supporting the GS66 in the EC-FM Tuner tool.

https://forum-en.msi.com/index.php?topic=148273.1400

This way all of you can have more control over the fans and at what temps they are triggered at.

 

I'll help, what do we need to do?

 

Svet says he is working on it as of today and it should be available in just a couple more days.

 

keep me posted!!

 

Just a heads up the latest 6/19 EC firmware,16V1EMS1.114, sets the minimum possible fan speeds to ~2700 rpm which is quite audible. You can revert back to the 5/19 EC firmware, 16V1EMS1.112, which has the minimum possible fan speed set to ~2000 rpm.
