    1. Choose a stable game and install it.
    2. Keep overclocking core and memory speeds in steps of 5 MHz and keep playing the game to see if you see any symptoms.

    You can overclock the memory speed a lot more than the core speed.

    rivatuner has a treshold level for both core and memory clocks. set the clocks to the maximum threshold (with arrows). run a game that stresses ur gcard, like doom3 or hl2. if u are a newbie, increase by the minimum amount of speed, like 1mhz per increase. if u are bolder, 5 mhz should be good, if u are rich go for 10mhz increase.

    info : check ur heatsink and gcard temperatures, change them for higher clocks. get a heatsinks with thermal pad and paste. (mine increase 30% performance using those on d3)

    he said he wanted to o/c for the 1st time, so jus tell him the safety to o/c, the choice is still urs, the moment u increase the card by 1mhz, the warranty is be voided.

    depends what card you have ;) About the warranty, Gainward's Golden Sample edition allows you to overclock with warranty ;) <3 Gainward <3
    But a 6800GT card, I run mine at 440/1200 without problems and stabel ^^

    malorg, does your 6800GT really run at 440? Thats a bit odd, you see the 6800GT is stock 350mhz, how is yours stock at 400mhz? that would be the equivalent of a 6800Ultra and 440mhz would be about the same as a 6800Ultra EE. For some reason your gpu specs seems bogus, no offence but they do.

    Gainward 6800GT 400/1100 @ ( sometimes ) 440/1200


    I think he meant his 6800GT runs @ 400/1100 and SOMETIMES 440/1200

    not stock 400 to 440 :p

    That's because your core clock is actually a multiple of the reference clock (for example my 5950 has a reference clock of 27 MHz).....So the speeds are all stepped......351 is the closest multiple of the reference clock that your card features so it is set to that speed automatically when you choose 350 MHz......
