ASUS Scar II (GL504GS) Thermal Testing, Undervolting and Overclocking
Take a closer look at performance, see if there are any problems and what can be done to improve gaming performance. In my configuration here, I've got the Intel i7 8750 H CPU with nvidia 1070 graphics and that's, the full 1070 no max q here so we've got a pretty well spec gaming. Laptop thermal testing was completed with an ambient room temperature of 21 degrees Celsius so expect warmer. Temperatures in a warmer environment also keep in mind there's a heat pipe shared between processor and graphics. So a change in one component may affect the other starting at the bottom of the graph at idle. The temperatures are a little warm by the light blue bars, even though the fans are still somewhat audible as you'll hear soon. Moving up to the green bar, I was testing gaming by playing watchdogs too, as it uses a good combination of CPU and GPU, and this gave us the highest temperatures. While gaming, the yellow bar, had the fans maxed out by enabling a Seuss's boost mode which raises the TDP of the CPU from 35 watts to 45 watts, so there's no temperature change here on the CPU as it's being sent more power. Although the graphics dropped by 6 degrees from the FASTA fans, with the fans back at stock speeds in the balanced fire file, but with the minus 0.09, our volt cpu 12 multiplied our next in orange, both CPU and GPU, or only one degree cooler than without Munda.
Bolting third we'll see how this affected performance in the next graph. With the combination of FASTA fans from over boost mode and unbolting applied, we see our best gaming temperatures and performance in light red. The stress tests were done by running a to 64 and the heav'n benchmark at the same time, in order to attempt to fully utilize both the processor and graphics moving up in the graph and starting with the dark red bar, there was the usual power limit throttling Taking place in the pink bar with over boost enabled that was still power limit throttling, but also intermittent thermal throttling. Now, to back on balanced mode in the purple bar with the under multiplied there's a all difference and then another slight drop to CPU temperature, with both fans maxed out and the under multiplied shown in dark blue. Although were seeing six to seven degree. Improvements on the graphics here from increasing fan speed. These are the clock speeds for the same tests just shown again starting down the bottom in green, while gaming, we can see a fairly nice improvement to CPU clock speed by a niggling boost mode, as the CPU TDP rises from its 35 watt cap to 45 watts. Although in the orange bar with boost, we can still get a nice improvement with the 0.09 volt on the Volt only with both the under vault and over boost mode, combined we're, seeing the full 3.9 gigahertz or core turbo speed of the i7 chip in the red Bar a similar story in the stress tests, when the combination of under volt and boost mode give us the full performance of the CPU.
If and under this worst case scenario test better than many other 8th, gen laptops, I've tested. These are the clock, speeds I've got while just running CPU early stress tests without any TV load. There are three built in profiles on the laptop called silent balance, stand over boost these limit, the CPU to 30, 35 and 45 watt tvp's respectively, and the fan speed also increases with each profile to aid cooling. We can see that under CPU only stress test. We get slightly better results with each profile, though not quite full speed, unless we also apply the under vault shown at the top in red to demonstrate how this translates into performance. I'Ve got some Cinebench CPU benchmarks here with the older seventh gen 7700 HQ just here. For comparison, even without the under multiply at the 8750 h score with boost mode is a little ahead of many other. Similarly spec laptops, I've tested with full performance achieved with our under vault. So a good result here are the GPU. Only clock speeds, while under a graphical, only stress test Berthoud stock and with a 200 megahertz GPU core of a clock applied, although on average in this test, were in leasing a 100 mega Hertz boost due to power limitations on the graphics. I wasn't able to modify this with Emma size afterburner. So how does this performance boost actually translate into games in the games tested? The exact same windows updates, game updates and Nvidia drivers were installed, so there shouldn't be any changes other than these CPU under vaulting and graphics.
Overclocking changes Far Cry, 5 was tested using the built in benchmark. The average frame rates were only just a little better, with a 4.8 improvement at Ultra settings with the overclocking and under vaulting. Applied fortnight also saw the same 4.8 improvement at max settings to the average frame rates, although this varies between setting levels. However, apart from low settings, the trend appeared positive, it does seem like we can gain a little extra performance with overclocking and under vaulting, although nothing too amazing, considering the results are already quite good, as for the external, temperatures will actually be put in your hands at Idle, it was mostly sitting in the low 30s, but rises to mid 30s in the center and at the back while gaming. This increases to the low 40s in the center and up to 50 right up the back a pretty similar result while running the stress tests. Perhaps a little warmer up, the back there with the fans maxed out in Nova boost mode. The temperatures seem to drop down by a few degrees. As for the fan noise produced by the laptop a lay of listen to some of these tests at idle, it was a little louder than most laptops with the fans still quite audible, despite the somewhat warmer idle temperatures shown early on, while gaming in under stress tests, The results are about the same and not too different from most other gaming laptops, I've tested, but then, with every boost mode enabled the fans do get quite loud.
Overall, the performance was pretty good for an 8th gen. I 78750 H laptop, almost all laptops, I've tested with the CPU have parliment throttling, and while that was still the case here, it was less of an issue compared to many others and could be fully eliminated. Even a distress test with a combination of over boost mode and extra under bolting applied these differences in performance shown aren't, hot and fast rules. There are different factors which will vary results, primarily the temperature you're running in application of thermal paste, and even the specific hardware which comes down to the silicon lottery. You may not be able to under bolt or overclock your hardware. The same as me, it depends on the chip and it's specific power requirements, so don't just blindly copy my settings and do some testing to find out where your stable point is for best results. For example, what I can usually get a minus 0.15 volt under volt on the 8750 H CPU, but in this unit only 0.09 o volt was possible. Well, you could probably improve the temperatures by swapping out the thermal paste that's, not something I can test in a review unit. If I go ahead and remove the stock thermal paste and replace my own, I can't put the old paste back, so the next reviewer would experience something different from what you'd actually see with the product and unknowingly report incorrect information due to what I've done under vaulting And raising the fan, speed, on the other hand, I'm physically intrusive and as we've seen, it did improve temperatures and gaming performance a little in this particular unit, with no downside once you've got a stable under Bowl.
Let me know how much of a performance boost you've found by under vaulting your hardware and what you thought of the improvements here and don't forget to subscribe for the full review of the asou scar, 2 gaming laptop as well as future tech.
