Dell G3 Thermal Testing – Undervolting and Overclocking
In my configuration here, I've got the Intel. I7. 97. 58 CPU, with nvidia 1060 m xq graphics serve fairly decent specs for a gaming laptop it's, also worth mentioning that I've got the 17 inch model here. In theory, temperatures may be a little warmer in the 15 inch version as it's a bit smaller with less cooling room, but I don't have it for testing. So I can't say for sure also keep in mind that the g3 is also available with the i 5 8300 H, CPU and 1050 or 1050 Ti graphics. I'Ve got the highest spec g3 here, so in theory, this should be worst case for it, as lower spec hardware will probably run cooler. Thermal testing was completed with an ambient room temperature of 18 degrees Celsius so expect warmer temperatures in a warmer environment. I'Ll also note that it wasn't possible to manually modify the fan speed of the g3, so all temperatures were with the fans at default speeds, starting at the bottom of the graph at idle. The CPU and GPU are running cool enough shown in light blue moving up to the green bar I've tested gaming. Using what shocks do as it uses a good amount of CPU and GPU resources, and this ROS. The temperatures are fair bit. If we apply a minus 0.15 volt under volt to the CPU we're able to drop the temperature slightly shown in yellow the stress, tests were done by running a 264 and heav'n benchmark.
At the same time. In order to attempt to fully utilize both the processor and graphics, moving up in the graph to the red bar, that was power, limits rattling present fairly standard with the 8750 hcv. You under stress test by playing the same minus 0.1, 500 volt under volt to the CPU in purple. The temperature actually rose slightly but as we'll see in the next graph it's now performing much better. These are the average clock speeds for the same temperature tests just shown. The green gaming and red stress test bars was subject to Powell them a throttling, which is why only a 3.4 gigahertz average was seen over all six CPU core, but performance was improved with the minus 0.15 revolt under multiplied. In particular, the purple bar shows that were very close to getting the full 3.9 gigahertz or called turbo speeed. If the 8750 h cpu. These are the clock speeds I got while just running CPU only stress tasks without any GPU load and power limit throttling was still taking place at stock. Although there was no thermal throttling with the minus 0.1 favored evolved under multiplied, though we're able to reach the full 3.9 gigahertz all core turbo speed. If the IEEE 78758 CPU and I'll also note that it wasn't possible to change the power limit from the 45 watt TDP with Intel XT year to demonstrate how this translates into performance, I've got some Cinebench CPU benchmarks here with the older seventh gen 7700 HQ just There for comparison, we're able to improve the score by over 100 points by applying the CPU on the vault and no real difference between either in terms of single quote performance as single core alone isn't enough to trigger Palamon throttling here at the GPU and the clock Speeds well, under a graphical, only stress test, Berthoud stuck and with a 200 megahertz GPU core of a clock applied but it's worth noting the SCP wonder, vaulting and GPU overclocking results will vary between chips based on the silicon lottery.
So how does this performance boost actually translate in 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 the CPU under vaulting and graphics overclocking. The same minus 0.15 volt on the vault to the CPU was applied as before, along with the 200 megahertz GPU core overclocked and 400 megahertz GPU memory or four clock. Csgo was tested with you, litical benchmark and with the changes in place. The one percent lows a slightly higher and average frame rates of max settings are about 7 percent better, but then no real changes at the yellow selling levels, far cry 5 was tested using the built in benchmark and again at Ultra settings. There was a similar 7 boost to the average frame rates in this game with higher 1 lows all round so we're, seeing a little improvement with the CPU under vaulting and GPU overclocking applied. Although it will depend on the particular game in question and the set levels in use, as for the external temperatures, where you'll actually be putting your hands at idle, the body of the laptop is peaking in the low 30s quite cool, while gaming. The rest rest was still cool at the center of the keyboard starts approaching 50 degrees, and, with the stress tests running, we saw a similar result. As for the fan noise produced by the laptop, the lay of a listen to some of these tests at idle, it was almost silent, apparently just audible, while gaming, the feds pick up, but overall it's, still a fair bit quieter compared to most other gaming laptops likely Due to the Mexican graphics and then about the same results with the stress tests running overall, the performance was about what I expected.
If the laptop like this with the 8750 H CPU, just to be clear, the power limit throttling isn't an issue unique to the Dell g3 I've, seen this in pretty much every eye: 78750 H, laptop I've tested, but as covered here, there are steps we can take To mitigate this and improve performance, mainly through under bolting, these differences in performance shown of hot and fast rules, there are different factors which will vary results, primarily the temperature you're running in application of thermal paste and given a specific hardware which comes down to the silicon Lottery, you may not be able to under fault or overclock your Hardware. The same as me, it depends on the chip and its 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. While 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, didn't 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, although with that said, pal limit throttling was more of an issue from my testing than hate anyway, but perhaps thermal throttling could become present in a warmer Environment under vaulting, on the other hand, isn't physically intrusive and as we've seen, it did improve the performance and temperatures in this particular unit.
With no downside, once you've got a stable under Bowl it's, a great way to get back some performance if you're running too hot or facing power limit throttling like we were here. 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 Dell g3 gaming laptop as well as future tech.
