Asus Strix SCAR 15 G533QS 150W TDP vBIOS on RTX 3080??

Hello, the Asus ROG Strix SCAR 15 G533QS seem to have a 130W TDP RTX 3080, however the Zephyrus Duo SE also has a 130W TDP RTX 3080 and I notice that some people actually flashed the MSI 150W TDP vBIOS on it for an increase in performance in exchange for extra heat.

Considering the SCAR 15 having way better cooling, I was wondering if anyone has actually tried the same thing??

I am still waiting for mine, I know there is a vBIOS for the 130W card that raises the lower limit to force the card to run at 130W at all time.

The SCAR 15 comes with a 240W adapter however compared to the 280W one that comes with the Zephyrus Duo SE.

 

Hello,
In truth the cooling system is superior in the zephyrus duo 15 Se due to the double air flow. Just see any stress tests to confirm that.
In addition, for what results from the Notebookcheck.net tests, the maximum stress consumption is ~200W so asus would have the option to make a future upgrade to 150W tgp (provided that this is due to a bug on the CPU as stated by notebookcheck.net)

 

Could you please provide the link as I havent noticed this bug being mentioned...cheers

The paragraphs concerned are:
-Stress Test
-Power consumption
Note that the review is based on pre-release drivers.

 

"We're able to record a maximum draw of 196.7 W from the large (~17.8 x 8.4 x 3.5 cm) 280 W AC adapter when running Prime95 and FurMark simultaneously. This overhead is unusually large which makes us wonder if the steep CPU clock rate fluctuates mentioned in our Stress Test section above could be a bug. The AC adapter is definitely capable of outputting more power to the laptop and yet the laptop never seems to demand it."

 

Wonder if that was already fixed with the bios 311 hmm

 

Cheers mate!


--->Can someone share vbios 150w from MSI gp76 3080? It can be successfully uploaded to strix scar 2021

Msi removed it from their website...

My Strix have 5800h and 240W still have some backup...
Cheers!

 

Looks like its fixed for strix scar 17:
"However, there have been improvements compared to the predecessor here as well. Since we measured a maximum temporary consumption of 227 watts, the 240-watt power adapter also offers enough leeway for performance peaks."

check on msi USA website. it was there today

 

Cheers mate Ive checked it already but nothing on msi forum part found ge76 vbios for 3080 dump from gpuz

Wo

wow
Thanks mate this is exacly what I was looking for.cheers

How u found it?went one option up and only pc vbioses no mobiles with 16gb hmmm interesting
Ahh its yours not verified upload...
You tried it already with strix or zephyrus?

 

Its done. My asus scar 17 with the 3080 works with 3080 bios from the ge76

 

Great news, let us know your results as soon as you can.

 

Which bios have you used? The one provided by dieandromeda?

 

I have 8% more performance in 3D Mark firestrike.
I use the ge77 msi bios. It works perfectly

 

So about the 12k?

 

Cooling in my SCAR 15 seems to be far better than what reviewers are saying, full on stress test on both GPU and CPU at the same time show GPU sitting at maximum 70 degrees LOL and consuming 130 - 140W of power.
CPU doing 90 degrees at 80W.

Fans are at 100%, its moving a lot of air for such a tiny heatsink, my Alienware M17x R4 heatsink is larger and has bigger fans yet does not cool the GTX 1070 as well as this Asus can cool the 3080.

 

How long were you running the stress tests and what were your ambient temps when you ran them? Is the 80W on the CPU and 130-140W sustained power draw?

 

The ambient temperature of the room was 22 to 23 degrees celsius.
The stress tests were using Prime95 on CPU, and MSI Kombustor and then I used HWiNFO for monitoring.

Test ran for 1 hour, I can test it again to confirm it today, I need to test the USB-C port more as it seems to be heavily bandwidth restrained when I plugged two monitors to it one 100Hz, both are 1080p, and 500Mbps internet, 4 devices and 3 peripherals.
Noticed only 30 fps on avg in Red Dead Redemption 2 with GPU only running at 750MHz, definitely strange only had time to test it on ext monitor, gotta do an int monitor test today.

 

from the video review i saw of the 15" rog strix 3080 being flashed to do 150 watts, even with just a few % increase, they started seeing artifacting that got worse and worse and they had to end the tests. I don't think it is sustainable atm to reflash bios to ge76. But i hope im proved wrong becasue I want it.

 

GizmoSlipTech?

 

Yesterday i flashed GE76 bios into G533 (5800h version) and did notice any artifacts during 1h CP2077 playthrough.
Temperatures and gpuz screen ( https://ibb.co/Sd94zcB, https://ibb.co/nnPWTQH). I will try to compare 115w and 150w in temperatures and performance later.

 

Can you tell us how to flash in the bios and make a backup on the old one? is it rtx 3080 gb you flashed in?

 

Do you have rtx 3080 6gb or 16gb ? vbios i only 16gb ? iits works to 6 gb?

 

I am wondering the same thing as Kvadde. Has anyone tried to flash a higher tdp vbios on a 8gb 3080 model?

Bios version appears to be the same. 94.04.3E.00.45 for all asus models. Mine is the G533QS-HF083.

GizmoSlipTech's original vbios shows the same version too.

 

Please let me know if this runs stably over some intense work. I'll play some intense games, but I want to also render a 4k video with lots of effects that might take 4-8 hours which will tax the entire system. I want the strix scar to be it. I'm mainly going for the 17" I need the screen real-estate, and I hear it has more empty room which would help with heat. I'll probably use a notebook cooler too. Run those tests!

 

Sure

Backup made via GPU-Z ( https://www.trishtech.com/2017/07/how-to-backup-gpu-bios-or-uefi-from-inside-windows/)
I used bios provided by dieandromeda ( https://www.techpowerup.com/vgabios/229687/229687)
for flashing used newest nvflash ( https://www.techpowerup.com/download/nvidia-nvflash/) and followed this guide ( https://www.overclock.net/threads/easy-nvflash-guide-with-pictures-for-gtx-970-980.1523391/) with few changes:

1. You no longer need to disable drivers
2. I had ID mismatch warning (basically you have to press y)

Remember that it is a little bit risky and be prepared for loading a backup and if you will fail any step dont restart PC and try to flash again (or flash backup).

 

Thank you but can i use 16gb bios to 8gb rtx 3080?

 

Have No idea

 

how is the machine performing after the flash? any issues? i flashed it couple of days ago and the power reading were no longer working so flashed back to the original one . is it worth flashing to the 150w one? thanks

 

and how is it? any stability issues? performance gain?

 

Not advisable to flash the 150W bios on the Scar 15. I have the Scar 15 and was testing with the 150W as I was planning to shunt mod to 160W. The temps even at 100% fan speed were approaching 90C. I'll be looking into adding additional heatpipes to the heatsink prior to shunt modding. 90C might be fine on the CPU, but on the GPU it's entering dangerous territory. I suspect the thermal runaway is partially why the 150W TDP vbios artifacts on the Scar 15, but the Scar 17s larger heatsink should have enough thermal capacity to avoid it.

 

Was that in stress test or something? Cause when i did it and flashed two days ago to 150w i had 78 degrees on the gpu playing cyberpunk for an hour

 

I flashed the 150w vbios on my scar 15 and with stock thermal paste I was running into the same issues. Repasted it with noctua nt-h2 and now it hit max 82 running time spy with (74% 74c, 91%,80c) with +100 core oc. With 100% fans, it should be easy to keep under 80c. Also took the opportunity to spread again the lm on the cpu. The scores were however lower then I expected, I was hoping for 13k graphical score but got 12762. After playing apex legends @1080p for a couple of hours on a external monitor, it never broke 75c, but I have everything set to low so gpu load is kind of meh.

I got the scar 15 after returning three ge76s due to qc issues, even with the same vbios there is still a visible gap in performance, at least in Apex legends. It is worth noting however that I have the lowest specced model with a 5800h and 2x8gb single rank, 3080 8gb. By the end of the week I will install some proper 2x16gb dual rank memory and see if it helps at all with in-game performance.

I still believe that ge66's 125+5 vbios seems more appropriate for the scar 15, the performance difference is not as big as one would anticipate, and it stays quieter, too.

 

Thanks for the details bro. Yeah i switched anyway to the original one and dont think it s worth it have the 125+5 one as not such a big differenfe. That s why i was looking into the 150w one

 

There was also a new vbios by Asus, I didn't get to try it. MyAsus installed it but before I realised I flashed the ge76's vbios, so I don't really know what they have changed, and MyAsus won't let me download again because apparently I have already downloaded and installed it. A guy in gizmosliptech's video where he flashes the vbios said that with this new vbios there were spikes up to 160w? I doubt they have changed much, but it is still worth checking.

 

Yeah that s the vbios i have as it did update mine and indeed there are spikes of 160+ i even saw couple of times 180

 

Have you noticed any improvements in games? The power limit is still 115 + 15w, right?

 

Yes same 115+15 , maybe improvements in gpu intensive games it keeps itsomwhow more close to 130w - 135w. Im still trying to figure how to use resizable bar. In device info it is turned to yes but in gpu-z it says disabled. And the other day it appeared enabled. Dont know exactly what i ve done to appear enabled though

 

Same with the ge76's vbios. It says it's enable on nvidia control panel but gpu-z says it's off. I guess Asus need to roll out a bios with resizable bar?

 

Strange though that it appeared enabled two days ago while i was playing with the bios but i dont remmeber which was it and what i did to have it enabled though. Well will have to wait and see

 

Well it's confirmed then, you can flash the GE76 RTX 3080 16GB VBios onto the ASUS RTX 3080 8GB. I'm pulling the trigger on one now as we speak, will keep this thread posted with my findings

 

I have the 16gb rtx 3080 not the 8gb one. So cant confirm the behaviour. But costalolstrax did it so might work asking advices from him

 

There is a couple of people on Reddit who have confirmed this also, I’ll try finding the thread if I can. But they said the MSI GE76 vbios can be flashed onto the ASUS, as the ASUS uses exactly the same vbios for the 16GB and 8GB variants of the RTX 3080. Meaning the hardware ID directly matches the MSI GE76 RTX 3080 if that makes sense.

 

Yep i get it , either way dont think that for a short period will do any harm for you to test and decide if worth keeping or not. Please keep the thread updated with your findings. Thanks and good luck

 

Will do

I'll definitely be keeping it long term, first thing I do when I get this laptop? Apply liquid metal on the GPU too, then put some new thermal pads on those vrms and start tdp modding, can't wait haha. I just hope that 240w power supply has some headroom, up to at least 250w would cut it.

 

Thermal pads are too thick for this laptop, you will need thermal paste. If you aply lm to the gpu, 150w will be easy in terms of temperature. I've been playing a lot this week (only apex legends, really) and so far I've had no issues at all with the 150w vbios. Stock thermal paste was ok though. The only known issue I have is that I can't read the real power draw, it shows 45-46w, but the gpu clocks higher and performance aligns with fully unlocked 3080s (~~13k gprahical score time spy)

Both msi and asus offer 8/16gb, I flashed mine after confirming that both models had the same id, and in fact if you check the download link on msi's website, both the gp66 with the 8gb 3080 and the ge66 with 16gb link to the same file. I guess I am a bit insane since that was enough for me to go ahead and flash it, but glad I did.

With the money I saved after returning the ge76 I bought the asus xg17 portable monitor, and that is still 400€ cheaper than the ge76 lol. Couldn't be happier. The scar runs quieter with much better battery life and keyboard for 1000€ less.

 

Hey guys, how's the cooling on the Scar 15 when it comes to CPU only workloads like Cinebench? Can it stay under 90s with power limits set to 80W?

 

These are my temps after the multicore run (score 12442). The performance is really impressive. Today I finally installed my 2x16gb dual rank kit. Sadly the bios set it to the same cl22 timings, but even then there was a massive improvement in performance. In fact I managed to get 12922 total score (13532 gpu, 10293 cpu) with +115 on the gpu core and 150w vbios, which turns out to be the highest score with a 5800h + 3080... Performance in games also went up significantly. Apex legends averages 215 vs 175 on a external 1080p 240hz display (3 long competitive matches for both averages). I haven't tested any other game, but I am sure the performance increase will be around the same in many competitive dx11 titles.
