Sudden FPS drops in intense games..

Likeandshare · Dec 16, 2013

Hi ppl,I'm having a issue here and i think its cpu related..

When i play games like LOL,World Of tanks,War Thunder everything is fine..but when i Play Battlefield 3,4 or Gta4..after some gameplay my fps starts droping from 70-80 to like 30-40 and stays so for some seconds and then gets back to normal..

My specs are:
FX-8350 (CM hyper 212 for cooling)
Asus Gtx 760 oc edition
2x4 gb Kingston Hyper X (8 together)
Asus M5A78L-M LX3
LC600H-12 v2.31 600 watt psu

Here is a n image of what happens when i play Bf4:

Could either be an issue with temp (not sure if those temp values are current or the highest it saw while it was open). or it could just be that BF4 is pretty hard on things. You're not going to get 80 fps constantly with a 760 on BF4.

I already know that about unparking didn't changed anything...for bf4 i know its full of bugs still,but why is it hapening in bf3 and gta4...only intense games..one thing is when i lower my cpu power usage in power options from 100% to 99% everything is ok in that games..but that is 600mhz lower on my cores :S.I wan't my cpu's whole power there must be some other problem,i don't think its the themps the reading is ok i think couse when i opened the case and it wasn't that hot..it was normal for my experiance..and the cooler is enought I think couse its stock,btw the setup is not ever 3 monts old.

Inadequate power from your PSU?

hapkido · Dec 16, 2013

It's throttling. Look at your CPU frequency line -- it dips way down a couple times.

you think its the psu?...yeah I noticed it ..when I set the power use to 99% it only uses 3.4ghz for every core,so I think I'm disabling its turbo boost with that option.

hapkido · Dec 16, 2013

If it was a bad PSU, it would probably just crash or you'd noticed issues with your GPU as well.

I would look at a heating issue or incorrect overclocking first. I spent a few minutes searching google, and 8350s start throttling at 61C core temp. You'll need to keep your CPU below that to keep it operating at max frequency.

when I used the stock cooler it went to 65c without this problem..and the cpu is already at its stock cloocking...but look at this..I found out that my motherboard don't have the fx8350 on its support list,its max wattage is 95watt cpu's but this one uses 125watt,can this be the problem?..I think that's why it don't happen when it' 99% power usage..aperantly it don't cross the 95 watt border.

hapkido · Dec 16, 2013

Yeah, that would be a problem....

Is it possible to update your BIOS to a version that supports Piledriver CPUs? Some motherboards will be able to.

Likeandshare · Dec 16, 2013

It's already the latest version,and i don't know what Piledriver is,For now i don't have the budget for a new mobo so i will try to stay at the lower clock,but when i have to upgrade can someone suggest me a good one for my configuration that actualy support my cpu,thx for your support guys.

I have the same problem and have tried everything.. The problem seems to get less with dropping frequency so I have come to the conclusion that it is indeed my motherboard. It worked fine with a 6core black edition in it at 4ghz but this 8 core when its in 4.1ghz boost mode (stock) i get dips in frequency and frame rate. I have an asrock 970 extreme4 (a cheap board) and have read pages of bad reviews on this board. Hope this helps.

I was just mentioning to someone in another post about this issue. Even if your motherboard says it supports the AMD FX-8350 it really won't unless you have something like a 6 + 2 or higher Power phase setup.

As a result I am inclined to push for boards with an 8 + 2 Power phase like these: http://www.gigabyte.com/products/product-page.aspx?pid=3907#ov

Thx for the info,I was hoping to get a n Sabertooth 990fx,will see if i can afford id first..if not ill look for a mobo with an 8+2 Power phase one.You helped me alot ppl.

Metallicat · Jan 2, 2014

yeah mine is 4 + 1.. Says it will support 140 watt cpu though.. >_< I heard it has to do with board heat and not cpu but it's all connected >_< grrr crappy board!

This table might help.

I'd recommend:
ASUS M5A99(F)X
GA-990(F)XA-UD(3,5,7)

That's a solid board. Reviewers have given that board a heck of a lot of praise too.

ElMoIsEviL · Jan 2, 2014

Metallicat :

Yes... that seems to be a pattern with many board manufacturers. They don't seem to factor transistor aging as well as diminishing returns once heat is applied to the mix.

JOOK-D :

All great boards as well imo. I tend to use the Gigabyte UD3 and UD5 board myself on many builds.
