Hello.. i have very little knowledge about overclocking and i was seeking help: i have a laptop Asus x72vn // GeForce 9650 (DDR2) 1 GB // 4 GB memory //VistaPremium // Core 2 Duo P8600 @ 2.4 Ghz i installed Rivatuner and i was surprised first that to access the video card settings i have to click on the customize button below (next to the box "Forceware detected") ..unlike what i have seen on the internet.. THen i dont have a "Fan" box to change fan frequency .. i was wondering by how much should i overclock my graphic card .. the default settings are (for performance 3D): Core Clock: 400 Mhz Shader Clock: 800Mhz Memory Clock: 400 Mhz Maximum is : 600 Mhz core and memory clock 1.Should i always keep core clock and memory clock at the same frequency or is there more efficient settings? 2.Should i change settings in the Overlay or Compatibility box ? 3.I suppose that i don't need to change settings for low power 3D (wich i can't anyway) and standart 2D right? 4.Why can't i change my fan frequency? I have been putting the following settings : 521/1042/525 5. I checked and after nearly 30 mins of playing gta 4 the temperature of my GPU was 70 degrees Celsius Is that ok .. can i go further ? (i heard that laptops can bear up to 100 degrees celsius) btw gta 4 works pretty good and fluidly (with textures set on high) .. 6. everytime i run rivatuner it sais : Warning! RivaTuner has not been tested with the currently installed display driver although i have the latest version: v2.22 8.Is there different combinations of Core Shader and Memory clock frenquencies specific to each game ? 9.finally what other programs can i use to increase my laptop's performances? THere are a lot of questions but beleive me you will be helping alot of beginners like me.
