    I7 4702MQ throttles badly (down to 0.11 GHz) at 89 degrees, is this normal?

    Hi!
    All my games are unplayable, please help me..

    If I've understood it correctly my processor throttles to keep the temperatures down, but should it really clock down to 0.11 (zero point eleven) Ghz when it reaches 89 degrees?
    When I play Crysis, LoL and so on my processor eventually goes up to those temps, and then it freezes completely (or 1-2 fps), which of course is unplayable.

    INTEL say it can handle 100 degrees
    ( ARK | Intel® Core)

    And both Notebookcheck and cpu-world also say 100 degrees.
    ( Intel Core i7-4702MQ Mobile processor - CW8064701470802)

    ( Intel Core i7 4702MQ Notebook Processor - NotebookCheck.net Tech)


    So shouldn't downclock itself at maybe 97 degrees?
    89 degrees seem way to early to me..

    How can I fix this problem? Can I somehow raise ”throttle-temp” from 89 to maybe 94-97 degrees?
    I mean, according to INTEL, it should be able to handle it.
    If not, can I somehow tell my computer to downclock itself just a bit at maybe 80-85 degrees (so it never even comes to 89 degrees, since downclock lower the temperature)?

    Picture:
    (For some reason the right side (where I play the games) is black, don't know why.
    If its too hard to see, the max-temps are these (per core): 89/87/89/89

    update the bios and tweak the voltage -50mv for less heat :)

    The first throttling thresholds are set in the embedded controller or BIOS. Manufacturers usually adopt conservative designs where they make the laptop throttle well before hitting the 100 degree Tjmax which is the point at which the CPU itself throttles. It is fairly normal for laptop makers to design the laptops to throttle at about 90 degrees.

    As for your CPU frequency, it could not have been at 0.11GHz as Haswell CPU's are unable to run below 0.8GHz. You should use a more reliable monitoring tool such as the aptly named ThrottleStop which will also help you stop the CPU from throttling. The use of ThrottleStop deserves a whole article dedicated to it so I'll just leave the link here: http://forum.notebookreview.com/har...arket-upgrades/531329-throttlestop-guide.html

    The ability to tweak voltages should not be taken for granted.. A locked down BIOS is the norm rather than the exception as far as I know :(

    Provided that the BIOS supports it, I presume? Let's see if the OP has luck..

    As suggested run ThrottleStop to get a better idea of what is happening. Throttling can occur due to other things than just temperature.

    Adjusting Haswell voltages does not require BIOS support. AFAIK this feature should be coming to ThrottleStop soon.

    If your seeing 0,11GHz then it would appear clock modulation is kicking in. This could be your BIOS or your OS. Perhaps you have set the OS CPU power options CPU cooling to passive rather than active.

    so as not mentioned yet when was the last time you cleaned the vents and fans out with compressed air. this is the number one problem for raised temps. a good clean out can lower by anything upto 10c
    next maybe think about new thermal paste on the cpu / gpu.

    i have same cpu..i dont get such high temp..in crysis 3(very high settings,high shader,fxaa) about 84-85C max..only state of decay and arkham city pass the 85C..but not over 90C..usually 87--88Cmax..The problem maybe for you is that you have also high gpu temp..I never saw my GPU going over 70C!!!even i overclocked it heavily(+ 135/780)

    Hi!

    Thanks you all for helping me!
    But I still have the same problem (and another one, which is more important!).

    This is what I've done:
    I've cleaned the vents and fan
    I've used ThrottleStop, it raised the ”max-temp” up to 92 degrees, but nothing more.
    If it's hard to read, my CPU goes up to 92 degrees and then my processor downclocks to about 0.8GHz

    [​IMG]


    BUT I've discovered that my processor downclocks itself quite randomly, even at lover temps..
    When I run ”Intel burn test” (that basically gets your CPU working at 100% to see how many Gflops it does), it downclocks to 0.8GHz without any reason.. (ignore the task manager that says 0.57GHz, what throttlestop says is correct)
    My max temps (as you can see in the picture) were about 80-84, so there is no way it was due to temperature..

    [​IMG]

    Do you guys now what I can do to fix this?

    Both are correct. While your CPU is running at 0.8GHz it is only running for 75% then stopping for 25%. It does this many times a second so the effective clock over a 1 second period is 0.75 x 0.8GHz. TS shows chip 75%, without throttling it would be 100%. Task manager shows the effective clock.

    You have a 37W TDP so don't expect it to not throttle with IBT with that limit. TS TDP log shows this has happened.

    Which laptop are you using? Check with one of the other threads for that laptop to see if they have the same problems. Did you check your power plan and if passive cooling is implemented?

    It's normal for clocks to drop at idle with power saving and clock up when needed.

    Sorry for the derailment, but based on this thread (and other things I've read), can I safely say that 4702MQ runs just as hot as the 4700MQ, except it'd be throttle-tastic due to the 37W TDP cap (and not to mention less performance)? If so, I'm going to caution my friend who is in the market for a Haswell laptop to stay far, far away from 4702MQ.

    The 4702MQ has lower clock speeds than 4700MQ. Neglecting variations in silicon quality, the 4700MQ running at full speed will be consuming more power than the 4702MQ also running at full speed. Since all that electrical power supplied to the CPU must be exhausted as heat, given equal thermal constraints, the 4700MQ will be hotter.

    The impression that 4702MQ is "just as hot" is probably due to the fact that it has a lower thermal design power (TDP) and therefore manufacturers feel justified in equipping a laptop using 4702MQ with a cooling system that is less robust than one that would be implemented alongside 4700MQ. Indeed, from the engineer's point of view, the design maximum CPU temperature for any laptop is roughly constant therefore effort should be made to use just the right amount of cooling capacity to ensure that the CPU does not exceed that design temperature.

    Remember, there is no such thing as free/magic performance. Increased clock speeds must be paid for by increased power/heat, other things held constant.

    For a definitive answer you'd really need to test both 4702 and 4700 with the same hardware at the same load and clock frequency. Even then different chips from the same model can run differently, one a bit cooler than the other.

    For a 4700 running at 3.4GHz with a 47W load would produce a ~40W load at 3.2GHz, not that much different from the 4702. If the temperature specification remains the same for both chips then the lower TDP of the 4702 would hint that it produces higher temperatures per Watt than the 4700. For instance running both chips at 37W might see a 6C to 7C difference in temperatures while at lower powers it will be less of a difference. If the 4702 needs a little less power to run at the same CPU load at the same clocks, 37W vs 40W, then that temperature difference may be closer to 5C.

    Hi again!

    If I've understood it correctly, we now know it's the 37W TDP that is the problem?
    Is there any way to increase this TDP? I know it will get hotter, but if I use a cooling pad, it might stay at the same temps as before?
    I want to be able to play som games, and not experience serious lagging every 5 minutes.

    Have you tried repasting perhaps maybe the company did it badly

    Wait no my bad I don't think you can actually open that thing without voiding the warrenty

    Perhaps what model is your laptop

    AW, Dell, HP ETC

    It's a HP ENVY 15.
    I don't really want to void the warranty, plus it seems like it's not even the temps that are my problem, but the 37W TDP.

    It takes 8 watts on a sandy bridge i7 to do 800mhz it is not the TDP

    On top of it this is a haswell processor it takes less then a sandy to do that

    If your processor is running at 89 C it is trying to stay away from 90 my alien hates the 95s however the alien has an unlocked bios the INTEL itself will throttle at 100 however the HP will force it to at 90 my alien by default is suppose to force the i7 to throttle at 90 C I'm gonna set it to 95 C but If I set it to 150 C it doesn't matter the i7 will throttle itself regardless of that setting at 100 C what Your hp is doing is telling the i7 to throttle rather then the i7 telling itself to throttle

    You cannot raise the TDP on a intel processor u can raise the max allowed to take at any given time if you have a motherboard that allows it but the TDP has a max but it's continuous in otherwords at 100% you could use all the 37ws but when your doing nothing UNLESS YOUR A CORE 2 QUAD you will NOT use more then 10w

    Now the only suggestion I have for that hp...is if it's still in warrenty EVEN IF IT'S THE BASIC 1 Year is to call HP and send it in for repairs about overheating I had a friend with an hp it ran at 200 F(93 C) and shut down while doing anything he sent it to the depot came back BETTER but not perfect now it runs at 180 F(~82 C) and if your sitting here doing 89C that's too hot the other guy who has 85 C is ok it's not great but it's normal for something like the envy that isn't a large desktop replacement <85 is ok in my opinion unless your doing insane OCs like my 4.5 down there mine holds 87 to 90 C when doing that constant....46 C at stock doing nothing and 68 stock full load

    Some time ago my cpu was throttling even at low temps due to other components heating up. Try untick prochot in Throttlestop: http://forum.notebookreview.com/sager-clevo/723019-2670qm-multiplier-stuck-x8.html

    Also sometimes, more often than I´d like, when I wake my Clevo from sleep mode (on battery) and plug the cord the cpu kinda stays in powersaving mode and operates at low speed constantly. I have to put it to sleep and wake it again to get normal speed. Though if you´re having full speed with sporadic throttling that´s not the same.

    Have you tried undervolting? My 4700HQ (in my MSI GS70) was throttling at 90C. I undervolted the cores -100mV with Intel XTU and it no longer throttles -> CPU runs 8-10C cooler. I hear all of the talk about 37W and I know my 4700HQ is higher, but it can't hurt to try, right?

    Bubzers is right undervolting could help but that's only If his hp has it unlocked to allow the changes

    Couldn't hurt to try though

    I can't send it in for repairs about overheating, because overheating isn't the problem.
    The CPU just downclocks itself for no reason.
    Here you can see it "throttles" to 0.8GHz at max 76 degrees. It's no way that's because of overheating.

    The computer has now been sent to HP for repairs ;)

    Is power profile set to "high performance"? Also are you certain core temp is reading the CPU temps properly? My i7-4800MQ will throttle at 89C as well, but it won't drop to 800MHz. Almost seems like a power issue to me.

    its overheating, it was clear from the start and will keep it so.

    to have such high temps with such a low frequency, there is no other way. to avoid meltdown the notebook simply throttles itself

    There's always a reason and the way it is downclocking is abnormal. Throttling can happen due to more than just the CPU temperature. ACPI and/or the EC have a lot of control over this. Things such as running on battery, unsuitable AC adapter, drawing excessive power, drawing excessive current, other components overheating such as the VRM and so on.


    Probably your best course of action. Hope you get it back quickly and working as advertised.

    Normal, no. Perhaps the fan is not working and/or passive cooling is being employed.
