AMD FX8150 throttling issues when new CPU fan installed

[DazKins]

So I've had an FX8150 for a long time now using the stock cooler, with this cooler the CPU would usually throttle itself at around 75 degrees which I was fine with.

A couple of day ago in installed a new cooler, Deepcool GAMMAX 300. THIS WAS THE ONLY CHANGE MADE TO MY COMPUTER SINCE THE ISSUE STARTED. Now I have been experiencing the same level of CPU throttling when my CPU hits around 45 degrees. This strikes me as VERY odd as 45 degrees is very cool for a CPU.

My motherboard is an Asus m5a78l-m with the american megatrends BIOS. I've changed just about every setting possible in the BIOS to try and prevent the issue, but there are no direct options that allow me to disable thermal throttling on the CPU.

Help is much appreciated I really am at my wits end with this issue! Thanks in advanced!

How are you sure the CPU is throttling?
It's highly unlikely that it would throttle at 45C 🙁

The clock multiplier goes from 20.5x (on CPUID) to 7.0x until it reaches around 30 degrees then goes back to normal

have you oc'd it or is it stock speed? like alex said them temps wont throttle your cpu, try resetting bios if you haven't all ready

turn off all the power saving features like cool and quiet and c6 and see if it still does it

is this under stress (ie prime95) it is normal for clocks to jump around during prime

I have updated the BIOS and reset it.

My CPU is currently overclocked but the same thing happens even when the CPU is at it's normal clock.

The main thing that's worrying me, is why the temperature at which the CPU throttles has changed when all I did was change the fan. Is there anyway to change this temperature?

This is under stress

the problem is you have no longer any airflow over the vrm's and they are overheating which is the reason your cpu is being throttled, put a fan over the vrm's

Sorry if this is a dumb question, but whats are 'vrms'?

 

[michaelhall]

try disabling all power saving options cool & quite c6 go to power options and set to performance mode also unpark cores there's a hotfix off microsoft google it

 

[michaelhall]

vrm's are power delivery components (little chips next to you cpu)

 

[DazKins]

Could this be an issue with the orientation of my fan? It is a side on fan so does it matter which way it faces?

why disable all power saving features? make their chip run hotter?

Something is probably wrong with the way you put the thermal paste on or it's clamped down. If you changed the cooler and things aren't working, the cooler is the problem, not BIOS settings.

Don't know why someone would say, change this and that, when the only thing you changed was the cooler, then the cooler is the issue in one way or another.

What are the motherboard temps? Run openhardwaremoitor and check the MB temps, which will give you the socket temp and the vrm temps usually.

My motherboard temp monitors don't seem to work. All 3 are fixed at constant values

i have the fx6300 and oc'd to 4.4ghz with the hyper 212 evo,, i was having this issue so i disabled all power saving options and unparked all cores and i was golden theres 2 updates microsoft put out for the fx chips to unpark cores which is another power saving thing i also did that and had no problems since hope this helps

 

[michaelhall]

even so... if your oc'ing these settings will help you out , you can always take note of what getochkn said and try reseating the cooler with a little less thermal compound (grain of rice)

 

[michaelhall]

and his temps are fine he wants to know why the clocks are jumping around

 

[DazKins]

A lot of people are mentioning the hotfixes for parked cores. Can someone link me to them? I only found this one: http://support.microsoft.com/kb/2646060/en-us
And it says it isn't applicable for my computer!

 

[michaelhall]

Windows6.1-KB2646060-v3-x64 , Windows6.1-KB2645594-x64 install them both has to be in a certain order cant remember which way but try one if is says not applicable try the other then the other one will install after if you know what i mean lol

Ok here's what solved it for me, will write it all here as the answer was spread across a few posts
Install this: http://support.microsoft.com/kb/2645594/en-us
then
Install this: http://support.microsoft.com/kb/2646060

MUST BE IN THAT ORDER.

Thank's so much to everyone that helped you have no idea how large of a weight you've taken off my shoulders now!

Does it also work on windows 8.1? having the exact same issues but at 65C and with an fx-8350, thank you!

 

[pianodomkop]

anyone?

 

[Alex Kelly]

Dunno, have you installed all of the windows updates?

 

[pianodomkop]

Yes i have, here is some more info on my problem. I have upgraded my graphics card to a msi 4gb r9 290 btw so that t\different in the spec list. Plz check it out and thanks in advance! http://www.tomshardware.co.uk/answers/id-2220125/thermal-throttling-story.html
