Just upgraded my CPU from a Phenom X4 955 to an FX-8150, now suffering massive framerate drops seemingly randomly.
Whenever it's running as should, my frames are at about 85-120, but about 2-3 times a minute for about 5 seconds, my framerate will plummet to 15-25 FPS tops then jump back too 85+. Also introduced with this CPU uprgrade, my sound will cut out/be garbled for a couple seconds at a time, sometimes corresponding with the framerate drop.


This is happening, most notably, in Battlefield 4. Though, I've seen framerate drops in Civilization 5 and Diablo 3, no sound cutting out though.

CPU: AMD FX-8150
Mobo: ASRock 990FX Extreme3
RAM: 8 gig Corsair Vengeance (1600MHz)
Video Card: MSI GTX 760 8gig
HD: Western Digital 1TB Caviar Black
SSD: OCZ Agility3

Disabling the Spread Spectrum in the bios lessened the frequency of the issue, still there though. I have been running the AMD Overdrive stability test for a while, no issues so far, though I did notice that sometimes the cpu multiplier will drop down to 7x, from 19.5x.
CPU temp hasn't gotten above 53 degress celsius.


EDIT: I don't suffer any framerate loss or sound distortion on empty BF4 servers.
EDIT 2: I use a USB-wired Plantronics GameCom 780.
 
Solution
you should try disabling APM in bios, so you throtling problem (7x multiplier) stops. maybe that's the solution, but i believe sound problems like you described are related to NB instability. check if NB frequency is higher than 2000mhz.

Just tossed in the edit, using a USB headset, not onboard. Not sure if this changes anything.

Yes, did update the bios and I have been noticing a lot of negativity about the Bulldozer architecture. I'll try disabling APM in the bios now.

Disabled APM, jumped into BF4, played a few minutes, no more FPS drops! I'm not sure if it was disabling the APM or if it was because I installed the hotfix.


Thanks all!

Clock for clock faildozer is slower than Phenom II. A real upgrade would have been FX 8320.

ASRock stopped support for the 8350/8320 for my motherboard. We bought that chip, was using it for a while, had a hard freeze, found that support was dropped for the 990FX Extreme3, so I grabbed my fiances 8150 and she has the 8320.


I've noticed a performance upgrade in BF4. Previously I could only reach ~70-80 frames, dipping into the 40~ or lower (in cases of extreme explosions), now I don't drop below 75 with 3 settings changed from High to UItra.
