Isn't it normal to have some amount of fluctuation on a daily basis due to difficulty changes and whatnot?

My 6970's range from 440-480 KH/s all day. A pool might record slightly different hashrates (from 350-550). Long term though it evens out to about 470kh/card

hey guys i seem to have a slight problem here.

i have 2 rigs with 4x gigabyte 270's each


they run at 470kh/s- 480kh/s each but here is where the problem is

if i let it run for lets say 2 hours it will start to lower all the cards so it will say 480kh/430kh

so im actually getting 430 kh/s.

i cant seem to find a way to fix this without having to restart it every like 2-3 hours...

any suggestions?
