[trifty]

hey guys.. id like to ask HOW do i OC my 4850 vaporx and how far can i oc it ? ive never oc anything in my life before but i get the idea by using CCC .. but im worried of the risks.. its now at stock GPU Clock - 650 mhz and memory clock set at 1000mhz .. id like to know if i OC it .. how DIFFERENT will it be ?? thanks guys im using the HAF 932 btw..the temp now at idle is around 40c .. when i play games usually it jumps to around 60 - 70 .. plz help

No one can tell you how far you can OC it, EVERY card is different in terms of OCing.
Make sure you keep an eye on those load temps, you don't want them going above 80C

The difference in performance won't be huge, but it depends on what resolution you play at and also what CPU you have.

The best way to OC your GPU is to go into CCC and up your GPU Core clock by 10mhz (From 650 to 660) then run a program called Furmark to test for stability and load temps, if its stable and you see no artifacts and the temps are good then up the mhz again by another 10mhz, keep doing this until it becomes unstable or the temps reach 80C

If needs be, back down 10mhz to regain stability

ohh okayy.. i run wit an amd phenom 2 x5 955 and i usually play at 1680 or 1920 ..

well its worth doing as its free performance, although it could take up a few hours of your time.

ohkay..erm i have futuremark vantage but while it runs the test it doesnt show the temps ? only fps and frames .. and time ..

No not futuremark vantage, Furmark

Download from here: http://downloads.guru3d.com/FurMark-v1.6.5-download-1965.html

Download and install that program, Run it in windowed mode and use CCC or GPU-Z to monitor temps.

if youre the adventurous type try out a volt mod. I voltmoded a his 4850 and got it to 816 core. how crazy you can go depends how good of cooling you have of course, but you can up the voltage a bit on stock cooling if you max the fan. heres the link to a good how to: http://www.techpowerup.com/articles/overclocking/151
