Use Intel XTU to raise TDP, & sustained clock rate, i7-8565 Spectre x360 13?

[seearghee]

I have a Spectre x360 13, with i7-8565 CPU, which has a TDP in this laptop of 15 watts.  However, exactly the same CPU in the Dell XPS 13 is shown with a TDP of 25 watts, which gives it a much higher sustained clock rate.  Has anyone used the Intel Extreme Tuning Utility to raise the TDP to 25 watts, and/or lowered the CPU voltage offset, to reduce power consumption & therefore heat, to enable the higher clock rate in the Spectre x360 13?  If so, what results did you get?  Did the Spectre CPU+GPU cooling system & fans cope with the extra heat generated?

Thanks in advance.

@seearghee Perhaps, you could tell us what results you've gotten, is your device overheating? do let us know, so we can troubleshoot and resolve the same,

Also, if the device is overheating, try these steps to resolve it: click here for steps.

Hi Riddle_Decipher, if you read my original posting, you will notice that I was asking if any other people had used Intel's Extreme Tuning Utility to raise TDP on their Spectre x360 & if so, what were their results.  I have NOT used Intel's Extreme Tuning Utility, and my Spectre x360 is performing fine, though slower on CPU intensive tasks taking more than a few seconds, than a Dell XPS 13 with the same CPU that I was able to compare it against, hence my question in the first place.

Given the example of the Dell XPS 13, the i7-8565u seems capable of operating safely for extended periods with a TDP of 25watts, provided it has an adequate cooling system & policy,   With a large heat sink & 2 fans, it looks like the Spectre x360 should be capable of providing similar cooling.  The problem would seem to be that HP only provides a passive cooling policy for this laptop, presumably to keep fan noise to a minimum.  It's a pity that HP does not provide a user selectable option for a fast responding Active cooling policy,  coupled with the option to raise TDP to 20 watts or 25 watts, so that the full power of the i7-8565u CPU can be utilized.  I'm thinking that could be accomplished by some straightforward modifications to the BIOS.  Would be great if HP would do this & offer it as an option, not only for this laptop & CPU, but for their whole range of laptops.  This would make HP laptops very competitive!

I also raised the question of undervolting the CPU, to reduce power consumption & heat generation.  Again, I have NOT done this, but have read posts on other forums of many who have done it, with generally positive results.  Only downside seems to be that if the undervolt is maintained when a computer goes to Sleep, it causes the computer to Restart.  From what I have read, it seems ThrottleStop is the preferred utility for doing this, as it is able to close down before Sleep & then restart when the computer comes out of Sleep, thus avoiding the Restart.  Intel's XTU doesn't seem capable of doing this.

Given the benefits, I'm surprised computer manufacturers - particularly those of slim laptops that often struggle to get rid of heat - haven't incorporated this capability during the manufacturing process, or offered it as an optional utility, instead of leaving it up to Intel & an apparently free utility.  Again, this is probably something that could be incorporated into the BIOS, and would seem to offer significant competitive advantages for the manufacturers that do so.

@seearghee Since no one attended to your query, I jumped in and I know you've not done any of it but wanted to know if someone else did, to get the results of the same, that said, I do appreciate your suggestions and I'll forward them to the relevant team so we could work on the same, going forward, although, not sure when that would happen, and yes you are right about the cooling policy, it is passive at the moment, and no we don't offer changed to the BIOS (for both the cooling or the undervolting of the CPU).

I hope that clarification helps, and if you need anything else, do let us know, 

Have a good day, ahead.

OK, thanks for getting back to me.  Let me try another question.  Would the warranty on my new Spectre x360 be affected if I used Intel Extreme Tuning Utility to undervolt the CPU?

[Riddle_Decipher]

@seearghee The pleasure is all mine, that said, HP does not recommend using such software as it may render the device unstable, as it isn't designed for the same, however, you are free to do as you please at your own discretion, it doesn't void the warranty as such, however, we wouldn't support with any software assistance on how to use it, etc.

[seearghee]

OK, understand you could not support Intel XTU, but if using it doesn't affect the warranty then I may well have a go at gradually undervolting till the laptop becomes unstable, and then back off a bit till it is stable, and see what difference that  makes to CPU temperature & performance.  Should be an interesting experiment!

[Riddle_Decipher]

@seearghee You could do that, just as long as the hardware isn't damaged due to it, 

So, Good luck!
