FX-8320 throttling?

[UnbendingNose]

I've got an FX-8320 on an ASrock 970 extreme 3 (got it for free) with an R9 290 water cooled and 8 gb's of ram at 1600mhz. I'm using bf4 as a benchmark and I've seemed to run into some issues lately.

 

I have v-sync off and I'm only getting anywhere from 40 to 70 fps in BF4 even if I turn the settings down all to low. My gpu usage never goes above 60% and my cpu usage never goes above 50%. If my gpu usage was capped at 60% and my cpu was running at 100% then I'd have a bottleneck but that's not the case. For some reason my CPU isn't being fully utilized and is holding back my r9 290.

 

I tried disabling turbo core and downclocking the cpu to 3.3ghz to see if it would keep the crappy 4+1 power phase from throttling but the cpu still runs under 50% in bf4. Any idea what might be happening? When I first got the r9 290 I would get 90+ fps in bf4 at 1080p ultra. 

 

I'm thinking about doing a clean install because it seems like something might be holding the hardware back in windows. Will try unparking my cpu cores later.

Yep that board is shit for 8 cores because of the crappy power phase and vrm's cooling.

The CPU doesn't actually have to be at 100% usage to be the bottleneck.

If you have it highly overclocked, the VRM may also be overheating.

I'd agree with what lani100 is saying, the VRM's on that board will get quite hot from the power hungry 8 core. The power phasing on that board isn't great.

That thing even throttled my 1100t on a slight oc.

[UnbendingNose]

Well I don't know how I was getting 100fps earlier and now can't even get over 70fps even on low now. I have the cpu manual clocked at 3.5ghz. Maybe if I reset everything back to stock settings and let it turbo?

I had that thing on an ASUS M5A97 LE R2.0 and that thing could barely handle it. I ditched it and got an M5A99FX PRO R2.0 and that's managed to push this thing to 5Ghz fairly happily

It's certainly worth a go, see what happens.

Voltage was at 1.35v.

Bumped it down to 1.23v and I seem to be getting more stable performance. FPS is staying above 60 for the most part.

Disable APM

Enable HPC

Set High Performance Mode in Windows

Unpark cores manually in registry

do what priller suggested it should help get more performance but your VRM problem will stay with you as long as you run this board...if you could somehow sell it to the most offering and get this board you would be golden:

This one has proper VRM's and power phases to run 8 core FX overclocked, i experienced this myself and it's a very solid board.

[bbqsauce]

you may wish to consider switching motherboards, otherwise you are just using a gimped 8320.

the 970-ud3p and 990fxa-ud3h rev4 are board good boards.

The board sucks monki kocks Z97 Intel master race.

That's the reason why I switched to intel bye AMD
