OCL throwing errors and works

Hello!
my OCL throws the following error no matter what i run:

------------------------------------------------------------------------
HWMon.GPU.#1...: -1% Util, -1c Temp, N/A Fan
WARN: ADL_Overdrive5_CurrentActivity_Get(): -5
 
HWMon.GPU.#2...: -1% Util, -1c Temp, N/A Fan
------------------------------------------------------------------------
The machine has 2 r9 cards.

the tool  does work and crack passwords, but i can't help think it might be warning me about something i should repair.
also, it might slow it down, and i need it to run at full potential.


Please assist!
thank you!
