8350 Downclocking to1.4GHz when temp reaches 60c how to prevent this?

post #1 of 15
Thread Starter 
my FX 8350 OCed to 4.7GHz (205x23.0) downclocks to 1.4GHz when it hits 60c.

Here's my Specs:
FX8350 (clocks stated), Antec H2O Kuhler 920, its 32c in here (manila, summer, still i need to overclock)
Gigabyte 970a-DS3P with Deepcool NBridge 8 as NB Cooler
2x4 1866 Kingston HyperX t1
AMD Asus HD 6990 Awsum bios default
Cooler Master Silent Pro M2 720w Bronze cert.
1TB WD Caviar Blue
500GB WD Scorpio Blue(files)

I play dota 2 in general and from 120fps it drops to 40+ fps because of CPU downclocking, i cant play BF4 or CPU extensive games like this because im afraid that will do something with my performance, i render videos as projects.

that's pretty much everything.

I've disabled cool n' quiet technology, so its out of the suggestions.

THANKS IN ADVANCE.

Try disabling any and all power saving features.
Cool n' Quiet isn't the end of things that can cause it to throttle down.

How certain are you that it's actually the temperature of 60c that's at fault? Did you monitor it during a stress test and witness is throttle at that exact speed or anything?

Willing to bet the VRM's are causing the throttling of your CPU. The motherboard can throttle the CPU to lower VRM temps/prevent failure. That board is a 4+1 phase. Not exactly ideal for a heavily overclocked power hungry chip like the FX-8350.

Had a similar issue with a low phase board and a Phenom II X6.

Thats a nice NB cooler, but it doesnt do a thing for your vrms. Youre going to need a fan on them plus a fan on the backside blowing on the back of the cpu and vrm area.

This. Disable C1E and APM and make sure Turbo is off.

im using coretemp as my monitor, yes im sure because when it hits 60c, i watch it go down to 50 and then goes back to 4.7

it is disabled cause its required to start overclocking. sorry didnt include that

Your VRM is overheating. Put a fan to blow on VRM, reduce overclock, undervolt.

Get a new motherboard. Put a fan on top of the vrm. Downclocking will be gone after that.

Fan probably won't help VRM's much, if at all. At the end of the day, it's still a 4+1 phase. You need to reduce your overclock AND voltage or get a different motherboard with more beefy VRM's to handle that kind of overclock.

that must be it, cause ive read articles/ forum discussions about how this board performs in overclocking, they only mentioned about not hitting 5.0. didnt know this is another problem.
