A10 7850K showing HUGE spikes on grapgh in BF4

post #1 of 23
Thread Starter 
Geting spikes in bf4 that is crazy. I´m using a dgpu (r9 270x) so it cant be because of the r7 in the chip i think. Tha cpu is overclocked to 4.4ghz wih voltage set to 1.5 and it dont get hotter than 45c (under water) so it shouldnt be the temps either. I have made a test using prime95 for 1 hour with no errors so i dont realy understand the huge spikes, and when i get the spikes the game like pauses or something or a split seccond (even in 16 player maps). The fps shows 45-165 so thats kinda weird to. Im using te lattest driver from amd with mantle enabled in the game. The reason i use manle is that i dont have to use v-sync and therefore get a higher fps, with v-sync enabled i get lower than with dx11 though. Anyone got a solution for this?

Thanks in advance.

You're probably throttling. The motherboard for those APUs are bad for it with any decent overclock. Not really a good CPU if you have discrete. I would sell it and switch to something like an fx6300 and up or or an i5. Tried Mantle? It looks crappier I think, but it could help.

1 hour isn't enough to test stability. How much memory do you have? Hard drive or SSD? Fill out your specs.

Nevermind, I see you tried Mantle.

8 gigs of kingston hyperx ram. 60gb kingston ssd (os only), 1tb 5400rpm hitachi hdd, a 500 watt psu, cooler master saidon 120v watercooler, 120mm spot cooler fan pointing at the vrm heatsink, 3xusb hdd. I have a theory that maybe its the psu not being able to run all of the stuff, but just a theory.

Cpu,vrm`s mobo temperature,gpu temperature,vrm`s video card temperature?gpu usage? All this while you play.

Also which windows do you have?

Only thing i saw with the overlay graph in b4 was gpu and cpu. Gpu didnt get higher than 25-30% whereas yhe cpu was between 10 and several million% (not kidding) and when it hit those high numbers it would pause for a split seccond (causing my death(s)). It didnt make much diffence if where to go down from 1080p on ultra to 1080p medium. As for temps the cpu never got hotter than 45c and the gpu 53c.

Forgot to say that the vrm heatsink was no more than luke warm and mobo temp never got hotter than 33c.

Check hwinfo and gpuz for more accurate results please

My temp readings where all from hwinfo. Would´nt gpuz show the same temp reading as hwinfo regarding the dgpu?
