As most of you with most videocards know, you can apply a simple series of tricks to boost the overall performance a little. You can do this at two levels, namely tweaking by enabling registry or BIOS hacks, or very simple, tamper with Image Quality. And then there is overclocking, which will give you the best possible results by far.
What do we need? One of the best tool for overclocking NVIDIA and ATI videocards is our own Rivatuner that you can download here. If you own an ATI or NVIDIA graphics card then the manufacturer actually has very nice built in options for you that can be found in the display driver properties.
Where should we go ? Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners not to increase the frequency any higher then 5% of the core and memory clock. Example: If your card runs at 600 MHz (which is pretty common these days) then I suggest you don't increase the frequency any higher than 30 to 50 MHz.
More advanced users push the frequency often way higher. Usually when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 10-15 MHz and leave it at that. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Look carefully and observe well. I really wouldn't know why you need to overclock today tested cards anyway, but we'll still show it ;)
All in all... do it at your own risk.
Check this out:
As you can see, the result is again a notably faster performing card. The game you are looking at is Call of Duty 4 with maximum in-game quality settings enabled. You can expect to push another 10% additional performance out of the card, completely free. This cream of the crop BE edition will really help you reach good results. We got the core to 810 MHz, the Shaders to 2000 MHZ and the memory over 2400 Mhz. Don't over-do your tweaks though.
Image Quality setting:
4x Anti Aliasing
16x anisotropic filtering
All settings maxed out
Overclocking results typically result into slightly more heat build-up in the GPU as well, but not with this cooler. Heavily stressed the core temperature rose towards ~78 degrees C. Still nothing to worry about here.
XFX GeForce 9800 GTX Black Edition review A review on the XFX Black edition GeForce 9800 GTX, after reading some of you guys will probably will run to the store .. as the XFX XXX and Black editions obviously have fallen in price after AMDs Radeon 4850 launch.
XFX GeForce 9800 GX2 Black edition review King of pre-overclocked products has to be XFX, their speed-bin of releasing OCed products is exceedingly fast. I do not think that there is an XFX product out there that is not available as a triple X edition or other series name slapped on top of it. Today will be no different, we received XFXes top of the shelf product, the GeForce 9800 GX2, the cool thing is that this is the new mystified named 'Black edition' series of cards, meaning it comes with a nice pre-overclock and an lovely game bundle.
XFX GeForce 9600 GT XXX 512MB review A review on that XXX rated version of the GeForce 9600 GT. Hey, only XFX can implement such a name for you. XFX have a "way" of communication and getting attention. They quite honestly deliver really impressive products. Today's tested product is no different.
XFX GeForce 8800 GTS 320 MB Fatal1ty review The Fata1ty Geforce 8800 GTS 320MB graphics card comes with it's GPU core pre-overclocked at 650 MHz and it's 320 MB memory clocked at (2x) 999 MHz. If that isn't rather radical, the Shader domain inside that graphics processor is clocked at a lovely 1620 MHz. Now if that does mean jack to you, these are the reference specs a 320 model normally has: 500 MHz core, 2x 800 MHz memory and a shader domain clock of 1200 MHz. Can you already sniff the performance increase ? That's like bacon on your eggs man.
