hello all sifu there ... i will get my 4850 today, can i know which software is the best to overclock ?
after i gone through the forum here , i found out many tools out there, can someone recommend me which to use ?

CCC ? ati tools ? ati tray tools ?

was planning to get the gainward GS .. but the price is increasing ... =.=

so i bought a 2nd hand sapphire 4850 .. hehe not bad, quite cheap (<RM500), just 3 months old

now running all cheap game with full effect XD
idle temperature 52c , loading 72 ++

come with stock cooling , max oc 690/1138

sorry, that one not really oc =.= i mean using the CCC auto tune function, the highest freq ... just for few minutes
but the temp would jump to 85 ...

but so far i think no need oc, coz all the game i using already max setting still smooth .. haha

how much lower temperature can this cooler achieve compared with the stock cooler ?

so , can u do that ? pls teach me
i mean auto fan speed when temp < 60c
fix fan speed(55%) when temp > 60c

wah nice one .. .but how much is it ?
now the good vga cooler so expensive, all almost RM 200

lower temperature coz better cooler,
it is just simple since Gainward GS using heat pipe technology

As quote from wikipedia
Wikipedia

A heat pipe is a heat transfer mechanism that can transport large quantities of heat with a very small difference in temperature between the hotter and colder interfaces.
Inside a heat pipe, at the hot interface a fluid turns to vapour and the gas naturally flows and condenses on the cold interface. The liquid falls or is moved by capillary action back to the hot interface to evaporate again and repeat the cycle.

if stock fan sure cant reach < 45 degree idle (unless ur aircond is inside ur pc)

those < 45 at idle usually aftermarket cooler, like gainward GS, battle axe cooler

for GS .. VERY EASY .. some could get 38 at idle

actually stock cooler we mean usally for normal fan cooler,
GS already modified the cooler designed with higher efficiency heatpipe and special cover for better protection and air flow.

all ur casing fan functioning well ?
or .. are u sure u r using GS version ?

now my pc got 5 cooling fan just for the CASING, hehe, my cheap sapphire 4850 at night can hit 49 degree idle

I was able to push my Sapphire 4850 to 700/1120 ..

but seem got some artifact in furmark stresstest .. XD
btw, my temperature still maintain below 49c .. thx to my Artic accelero twin turbo cooling ^^
