ghz dropping of AMD fx 8350 Eight core processor (4.00GHz)

oepsheadshot1 · Mar 28, 2015

So a few days ago i started noticing frame drops while i was gaming. At first i thought it was a one time thing but it started reappearing more often, so i did a little research and i could not find the answer for my problem. The only thing i noticed was that my ghz of my processor dropped and my fans started to blow less heavy. (i have checked my power saving setting, and even tried to cool my pc with a large fan... none of it worked) i hope that someone could help me with this

could you explain a little more about what you did?

use MSI afterburner, leave it running in the background when you game, when it start to slow down tab out of the game and take a look at the graphs. see if you're being RAM starved, your gpu is maxed out or your cpu is being maxed when it happens.

download hw monitor, and leave it running too. check out the max temps as well

if your motherboard is hitting 72C you're probably being throttled by the motherboard, if the cpu is hitting 65C your cpu cooler isn't good enough and your cpu is being throttled.

Full system spec mate ??
Especially motherboard

ASrock 970 pro3 r2.0 thats my motherboard, graphics card: r9 290 msi, i will try msi afterburner and see what it does thanks for the help

did the tests with afterburner cpu usage was mostly around 100% except when the frames/performance was dropping then it lays around 20 or less.The cpu temperatures where around 60+ degrees celcius

Afterburner will do nothing mate - your board is likely throttling - its a fairly poor board for 8 core chips.
Are you using an aftermarket cooler??

oepsheadshot1 · Mar 28, 2015

yes i am using a cpu cooler from be quiet, +the computer was pre build so the motherboard shouldn't be a problem i think, i have made some changes like the cpu cooler and a new graphics card and thats it.I haven't had this problem in the two years i have had this pc

oepsheadshot1 · Mar 28, 2015

btw my pc was originally from www.alternate.be its a very relliable source

madmatt30 · Mar 28, 2015

Have these problems started since you fitted the new cooler ??

The pro 3 has fairly weak vrm's - a tower cooler removes secondary cooling that is supplied when using a flat blower cooler like the and one.

I would drop into bios & disable turbo core/boost to see if it makes a difference.

ingtar33 · Mar 28, 2015

yeah. that board is a bad board for fx8 cores. if the cpu was 60+C then the socket was much higher. chances are your VRMs are overheating and the motherboard is throttling back your cpu.

oepsheadshot1 · Mar 29, 2015

madmatt30 no i have had the cooler a long time hasn't caused any problems btw the model is shadow rock 2.
But it it has started since i upgraded my graphics card.

madmatt30 · Mar 29, 2015

What's your PSU model mate ??
The 290 is incredibly power hungry ,paired with an 8350 you're wanting pretty much a 600w to be safe.

oepsheadshot1 · Mar 29, 2015

i have a 600w PSU so thats not the problem i think

oepsheadshot1 :

It is a poor motherboard that is very prone to thermal throttling as it has poor phase power. ASRock uses cheap components. Crappy mosfets, weak chokes etc..... A real motherboard is a ASUS SAbertooth 990FX R2. That ASRock board is cheap for a reason. It is a poor board. Good feature set but poor electronic components.

oepsheadshot1 · Mar 29, 2015

But when i had my 270x it didn't had that problem while playing the same game

ingtar33 · Mar 29, 2015

yes, but the 270 draws like 1/3 of the power the 290 draws, which means the 290 is dumping 3x the heat into your case.

oepsheadshot1 · Mar 29, 2015

So you are 100% sure that it if i replace my motherboard the issue will be fixed ?

ingtar33 · Mar 29, 2015

oepsheadshot1 :

if it's a heat issue and you get a good motherboard, yes.

Just to further reassure you I used to have an 8350 paired with a Gigabyte 990FXA UD3 and had the exact same problem as you. I upgraded to an ASUS Crosshair V Formula Z and it solved the problem. It's a little pricey but many agree it's the best AM3+ board you can get.
