Power Limit Question 7950 cf

post #1 of 2
Thread Starter 
Hi i have my 7950 cf's at 1150/1400 perfectly stable however in some games like shadow warrior at 2560x1440 max everything, the temp rises to about 87-88, with power limit +20%, now i havent tested to see if framerate is the same however, regardless of power limit % setting i set it at, the graphics cards do not throttle, and they dont lose any voltage (1.25v core 1.6v mem) they do however lose temperature(0% power limit 74C~, 10% power limit 81C~, 20% power limit 87-88C~) now my question is, if i dont lose fps, and dont get throttled, why run higher power limit %? it just causes unnecessary heat. should i test at different power limit %'s until FPS starts to drop and use that setting to reduce heat?

ok nvm, power limit just raises the headroom before it throttles, the heat is that high in some games depending on the drivers/how their coded. i have no other choice but to lower to say 1100 core and possibly 1.2v with afterburner, trixx works if i disable StartCCC in msconfig startup.
