R9 390 core clock issues

[Guest]

My Asus R9 390's core clock(on battlefield 4) sits anywhere imbetween 300mhz and 900mhz, no where near my oc clock of 1150mhz. During this time the card is also maxed out(100% usage). Is there any way to force constant core clock(i am on crimson 15.30.1025.1001)?

The rest of my specs are:
FX-8320(OC'd to 4.8Ghz)
Msi gaming 970 motherboard
Thermaltake TR2 RX 850W PSU
WD Black 1TB drive



Thanks for any help!! 😀

Its and powertune. It can be 100% but still sit lower clocks if vsync being hit or it deems higher clocks not needed.

You can try a programme called clockblocker, but with me it read the bios and locked at 1080 rather than my 1120 oc. I just let poeertune work now...actually works fine. I turn off vsync, turn on triple buffer and set frame rate cap of 65 in rivatuner.
By the way, how'd you get 1150 core? I'm at 25mv and 1120..
