Low CPU Frequency on Full Load

Neelabh Thakur · Aug 3, 2015

so i am having this issue in the CPU intensive games like GTA V and Watch Dogs when i start the game they work fine for 10-20 minute then fps drops to 20 from 45 i never had this issue so i decided to search about it and i realized that it happens because the CPU frequency drops to 1596Mhz from 3092Mhz this is the reason the fps drops then it goes back to the 3092 again and i get the same fps as before it happens in every 10-15 minutes when playing all the games its too annoying my processor is intel core i5 2400 3.1Ghz (its not overclocked and i never overclocked it before too) my temp is 70'c on full load and 45'c on idle so when the cpu is running on 3.1Ghz the temp is 70'c and when the frequency drops to 1.5Ghz the temps drops to 62'c too but i don't think my CPU is throttling because of the heat i have an aftermarket cooler as well Cooler Master Hyper TX3 EVO by the way i am getting this issue after i got this cooler my old cpu cooler stopped working so i bought this one and from today i noticed that issue please help me i tested prime94 too the temp is 66-68'c and even in if the frequency drops the power management mode is already on the high performance i can't find a solution out of this problem :'(

My Specs :
Asus Strix GTX 970
Intel Core i5 2400 3.1Ghz
Intel DH67CL Motherboard
Cooler Master PSU 750W
Cooler Master Hyper TX3 EVO (CPU COOLER)
Cooler Master CM 690 III (Cabinet)
8GB RAM

UPDATE :

i just checked the temps with HWMonitor and here are the results

Hi, what is your GPU temperature?

It might be worth going into the bios when the pc first boots and looking to see if any of your 'c' states are enabled. They're sleep/power saving features. Try disabling those and see if it keeps your cpu from dropping to idle/power saving frequencies.

it's 65'c-70'c on full load

so i should turn these off in bios i know about the intel speed step feature but disabling it will run my cpu on max usage always won't it harm my cpu ? is there anyway to run the cpu on the full frequency when gaming before it was full after installed this new cpu cooler i am having these issues is the cpu cooler related to it ? can thermal paste be the issue because i feel like that the the shop guy had applied too much of it :/ i had seen a video and he had applied the thermal paste as much as that guy and people said in the comments thats he applied too much thermal paste here is the link of that video he applied as much as this guy https://www.youtube.com/watch?v=j3cfA2xD6vI

Intel speed step allows the cpu to drop speed when not in use, so if it's not in use it should downclock. That shouldn't be the case during a game while it's using the cpu. The c states are power saving states, different from speed step. That person in that video used way too much thermal paste. Too much thermal paste would result in poor temperatures. You might achieve better temps with a better application of thermal paste but it's not causing your issue. Your temps are still 65-70c, which isn't high enough to cause thermal throttling. That's the only way thermal paste application would have anything to do with your cpu slowing down in the middle of a game, if it got too hot and throttled back the speed suddenly.

thanks a lot for the quick reply so c state is a different thing right what should i change in the settings and it was like that from the start i never had this problem i am having this after i got the new cpu cooler and yes that guy applied too much thermal paste it was my mistake but that time i was a noob not to know its more than needed and yes 71'c is the highest i think when playing gta v and watch dogs but the cpu frequency drops in the middle of a game so the reason is the c state settings ? in which way should i send the settings that they don't drop in high usage (like in gaming) but drops idle to save power and temp ? so sorry for bothering you i am a noob in hardware stuff and yes temp drops with speed as well the temp drops to 60-62'c when the speed drops to 1.5Ghz from 3.1Ghz as well in the middle of a game i tested prime94 too it frequency drops while running the prime94 too its totally random and when it drops the fps drops in the game then in like 1 minute it gets fixed again tis so annoying i haven't touched anything in bios since i bought the PC so i have no idea about these stuff! :'(

Update : i remeasured the temps with HW Monitor this time before i was measuring them with the speccy and msi afterburner but this time i did with HW Monitor http://i.imgur.com/aC9KwQN.jpg?1 see this :'(

core temps are normal but the CPU temp was too high shouldn't the PC reboot at that high temp

Update : i solved my issue i guess it was the faulty cpu cooler i am using my old cpu cooler again (it had broken and its still broken but the guy had fixed the fan with the glue) Cooler Master Vortex 211P now the temps are the same as before 70'c on the load sometimes reaches 73'c on highest in the gta v but the frequency drop is gone thanks a lot for the help anyway mate i will RMA my new cpu cooler
