Intel i7 won't boost to 3.5ghz when stressing cpu

[lukall87]

I have an intel core i7 4710hq that is capable of turbo boosting up to 3.5 ghz, but no matter how many cores I am using in intel extreme tuning utility, it won't go past 2.49ghz. I have it slightly oced/set to go up to 3.7ghz, but it still won't go past 2.49 ghz. I have gotten it to go up for short periods of time by changing the core frequency while stressing the cpu, but after a couple of minutes, it always goes back down and won't come up again. Temps never break 75 at 2.5 ghz, and never break 88 when I get it to boost. Thermal throttling also turns on to about 10 percent when it boosts, even when the temps are below 75. I am getting an external fan to try to get the boost temps below 80. Any help would be appreciated. Thanks

intel core i7 4710hq oced to 3.7ghz
nvidia geforce gtx 860m 4gb oced to 1232 mhz core, 3001 memory

drop the overclock and change it back to stock, as it seems that temperatures are causing the thermal throttling.

What are you using to "stress" the cpu?

Boosting to 3.5ghz is only available when 1 or 2 cores are being used and you have thermal headroom.
If 1 core is being fully used you can get boosted to 3.5.
If 2 cores are being partially used you can boost to 3.5.
If 3 or more cores are being used you might get a short boost and the throttle back to 2.5ghz.
The cpu will not boost when 2 or more core are being used @ 100% load which Intel extreme tuning does.

Overclocking a laptop is a very bad Idea to begin with.

it throttles at stock too when i get it to go over 2.5. the temps never get over 75 at that speed though. I am using cinebench and catzilla. it throttles when 1 core is used at 3.5 ghz, and if 4 cores are used, it can still get up to 3.3 ghz stock. ive seen it.

 

[lukall87]

I just ran cinebench at default 2.5 ghz and got a score of 490. I then ran it again and got it to boost to 3.4 ghz using 4 cores, and got a score of 610. But as soon as the bench mark finished, it went back to 2.5 ghz and stayed there.

This post is spot on.

I just ran cinebench, at it was going at 3.41 ghz on all cores according to intel extreme tuning utility. and i know ocing a laptop is a bad idea. i always watch the temps, and i never over volt it.

There ya go,
i can tell you that even an i7 3770k will not hit the 3.9GHz turbo during stress unless multicore enhancement is enabled. I imagine Laptop Motherboards leave that off and for good reason. if 3.5 is the trubo spec. The i can guess that the frequencies are 3500 one core 3400, 3400MHz, 3300MHz or something like that

 

[Vitric9]

I mucked that up, slightly dyslexic today

 

[lukall87]

its 3500, 3400, 3300, 3300. I might have somewhat fixed it. I went into advanced power options, and turned both the minimum and max processor state to 100%. it now idles at 3.31 ghz with one core enabled.

Don't overclock and also on gaming laptops to be able to reach max performance you need to have your charger connected, especially if you want to go with high performance mode, otherwise you will damage the battery very quickly. Again, can't stress this enough, never overclock on a laptop unless you really know what you're doing, even a cooling pad isn't enough because they're so compact.

 

[lukall87]

Don't worry, i am constantly watching the temps, and I never game without a charger. My laptop disables the discrete gpu on battery, and sets the processor to 2 ghz or something.

 

[Suzuki@1473780084@1473780163]

No this is not about the temps, you will actually damage your battery, as in eventually it'll stop working. If it's internal (can't be removed) then that's not a good thing. It's good that you don't game without a charger, as it will give you a small boost in performance, but what I don't like is the fact you overclocked your CPU. The i7 is fast as it is, you will not experience a performance boost big enough to notice, instead you'll shorten the life of it.

 

[lukall87]

The battery is internal, but it is easy enough to go in and remove it. I have done that before. And I know that ocing shortens the life, this laptop was only meant to last 2-3 years, its already over a year old. I don't think hitting the max of 3.5 at 4 cores instead of 1 is going to shorten the life that much anyway. I have an old Pentium thats been happily oced for 5 years.
