Međutim, Ive found out how to unlock it. So lets take a look at how to do this and see what sort of a performance improvement we can expect from undervolting the GS66.. Do sada, all 10th gen Intel laptops, Ive tested cant, be undervolted with Intel, XTU or Throttlestop, presumably due to the Plundervolt vulnerability. Im, not certain, but think that undervolting in BIOS should still be possible. As long as the BIOS supports it. After skimming the Plundervolt whitepaper, it sounds like the bug is exploited through the softwares ability to apply undervolting. With the Gigabyte laptops I tested. I didnt see a way of doing that in the BIOS and by default the GS66 doesnt offer this either. That is until you enter the advanced mode, which is as easy as pressing right shift, pravo, control, Lijevo, alt and F2 obviously. Once in this mode, go into the advanced settings scroll down to the overclocking performance menu enable the overclocking feature then, from here you can change. Xtu interface from the default of disabled to enabled.. Zanimljivo, there are no warnings about security issues or anything when changing it. It just lets you enable it.. Weve also got the option of undervolting the CPU through the BIOS itself, so this can be done even without using software like XTU or Throttlestop. If you prefer. Osobno, I prefer software so have enabled XTU Interface its easier to recover from when things arent stable.. It makes perfect sense that we get the option to change these things in the BIOS.

Its an unlocked K, processor so Id be disappointed if that wasnt the case.. To je rekao, fortunately, this feature isnt limited to the GS66 laptops with K. Cpus Tim from Hardware Unboxed confirmed that the i7 10750H model of GS66 also allows you to enable undervolting and undervolt through the BIOS in the same manner.. After saving the settings and booting into Windows. I confirmed that undervolting was now unlocked in XTU and worked as expected. So lets check out some revised thermal testing and see how this helps. All testing was done with an ambient room temperature of 21 stupnjeva Celzijusa.. The stress tests were done by running Aida64, with only stress, CENTRALNA PROCESORSKA JEDINICA, checked and Heaven benchmark. U isto vrijeme, while the gaming results were done, playing Watch Dogs, 2. Ive highlighted the new undervolted data. Here I didnt try to tune the undervolt and just selected 0.1v a value Id expect most to hit no problem.. We can see that temperatures havent really changed on the CPU when under stress test, but the GPU gets a bit cooler. Presumably due to the shared heatpipes changes to the CPU do affect it. In the games. We were just seeing slight 1 degree improvements on the CPU, though more of a change to the GPU temps. Ill. Also note that although the thermal throttle limit is set to 95 stupnjeva celzija, I did see the option to boost this in the BIOS.. While I could have done this to squeeze out some extra performance, I probably wouldnt recommend it just for longevity.

95 is already a fairly high limit. Po mom mišljenju, if it were my machine, I might be more inclined to cap it to 90 instead., Regardless its cool, that the option is available in the advanced BIOS.. These are the clock speeds for the same tests. Just shown. Were seeing a nice boost to the CPU performance, especially in the stress tests around a 300MHz boost over all 8 Jezgre. For such a simple change isnt bad at all.. The games also saw a similar, fair improvement. mislim, with all improvements in place, the 4.4GHz all core turbo boost speed was being hit.. It was interesting that it didnt go higher because XTU reports, the all core CPU boost speed as 5.3GHz, so there may be some setting in the advanced BIOS. That needs to be adjusted to affect that., Either way. I cant complain about this performance, especially when you remember the CPU was at 83 stupnjeva ovdje., When looking at the TDP reported by hardware info were not seeing too much change here, and this is because the power limit was still being hit, but the undervolt allows us To get more done within the power limit, Dostupna. Boosting the power limit in XTU didnt do anything to help, even though PL1 is set to 65 Watts, so I might need to get into the BIOS to boost it up. Further. The power limit. Dynamically boosts up as thermals improve, which probably explains why the power limit, boosted in the stress test with the undervolt applied it was running cooler.

Heres how Cinebench performance improves with the same undervolt in place.. It was possible to boost the multicore score by 11. With this honestly, pretty average undervolt, you could definitely push it. Harder. CPU only clock speeds improve a similar amount with the undervolt in the Aida64 stress test. Were still power limit throttling. Međutim, the undervolt allows us to get more work done within the power limit.. The undervolt also drops the temperature just a little extra, despite also offering better performance, so you could definitely take advantage of this and mod the GS66 further with the billion options in the BIOS. If you know what youre doing. There are plenty of settings in there, so you can tune until your heart's content, but as bob of all trades mentioned on twitter, if you dont know what youre doing you could do some damage., Let me know what you thought of The improvements by undervolting down in the comments Im just glad that its still possible with the GS66, even if it is a little out of the way and slightly hidden.
