AMD-FX8350 Slow down under load.

kylerpatters · Mar 29, 2014

So I've had my FX8350 a while now, and for everything gaming it's been fine.
But recently i've been streaming, and at 720p, with PC gaming, when the CPU hit's around 70% the CPU slow's down to 1.3ghz, and everything runs slow, FPS drops, stream lags and it's just not fun.

I've been all over google trying to find an answer, I've unparked the cores, double checked the power settings that it's not being limited there. I'm at my wits end now.

I'm not too tech savy in the way or overclocking or anything, so everything there is stock.
I have turned off Cool n' quiet and all that bs in the BIOS.

So if anyone has an answer to why it's doing this, that'd be great.

As far as i know some systems under clock themselves when they pass a certain temp limit not fully sure but i heard of such things

kylerpatters :

As KillStreak said, the only "normal" condition in which a CPU should downclock under load is if temperature is an issue. Download e-leet tuning/cpuZ or some monitoring utility. Check the temps when the chip hits ~70% load.

If not that, you may have a bad CPU

Just built my friend an FX 8320 system and it wouldnt run over 1.3Ghz. Had to return it.

I would guess it's a temp related issue as has been suggested above.

Run this program in the background while you play a game or stream. http://www.cpuid.com/softwares/hwmonitor.html Post a screenshot here after you've been playing for a while.

It could also be a need for a BIOS update. You can go to your motherboard manufacturer's site, find your motherboard model, and update the BIOS.

Are you overclocking? And what cpu cooler and case do you have? It's looks like a overheating issue

There is no reason to turn C&Q off. It's unlikely that disabling Turbo or any core-boost function will have that big of an effect on an FX-8350.

Gigabyte motherboards are bad to over-volt AMD CPUs on "Auto" volts. Use HWMonitor to chart your volts at idle and load and post your results (along with temps)

Hi, my cooling is the Corsair H40 liquid cooling.

If you need anymore information, just shout, I'm really not all that smart when it comes to this stuff.
I only turned c'n'q off and other things because other people said it have solved their CPU slow down problems.

I should be able to cool the beast down post an image with temps under loads.

kill streak · Mar 31, 2014

sorry not 'I' "IT" should be able to cool the beast down. PLease tell the temp of your cpu under load

Sorry for late reply, been away from the PC most of the week. If you look at my previous post, the temp hit's 44c before it does the weird slow down thing. I've never seen the temp go above that. Maybe to 45c in the whole time I've had the processor and cooler.

Because when it does the slow down, my rainmeter also says the temp goes to 29c which is strange, and if I open Task Manager, it says the overall CPU usage is only about 30% and the speed is 1.3Ghz, It's something I've never seen before, it'll be like that for 30seconds maybe, then go back to it's usual temp/speed till it does it again, rinse and repeat.

Hey what case do you have

konawolv · Apr 6, 2015

Make sure windows power management is set to Max Performance and not anything else.

Windows power management was downclocking my i7 4790k to 1.3 ghz when i would game.

H40! Lol! You need at least a 240 mm all in one or a real good air cooler like an NH-D14. An H40 is a cheap toy.

Unless you have a good, stout 990FX board with 8+2 phase power it very well may be thermally throttling so the mosfets don't catch fire or explode.
