Overclocking & Tweaking
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's tested card anyway, but we'll still show it ;)
All in all... do it at your own risk.
Now here's where things get even more interesting. The GTX 260 Sp216 seems to be a grand overclocker.
GPU clock frequencies:
- The reference clock for the card is 600 MHz, we ended up at 696 MHz.
- The shader domain clock for the card is 1500 MHz, we ended up at 1743 MHz.
- The memory clock for the card is 900 MHz (x2 effective),we ended up at 1038 MHz (=2076 MHz effective).
Our overclock was on the fly, and fairly easy to reach actually. I would not be surprised to see you guys yield even better results. We used Rivatuner, here's what such an overclock will get you gain, performance wise:
* Brothers in Arms hells Highway Image Quality settings maxed out.
Please, don't over-do your tweaks though, and be careful as overclocking typically is not covered by product warranty.
In this review we'll have a peek at the warmongers from KFA2 (Galaxy), they unleash this cute little beastly looking GTX 550 Ti LTD OC White edition graphics card. And to make it even more special, they slapped all components on a sexy white PCB again. Armed with that atypical looking cooler you'll learn that this product makes no compromises, you will not hear it, it will not run hot and it even comes factory clocked at a full GHz, quite amazing as GPUs seem to slowly pass that weird 1 GHz threshold.

We test a product from the guys at Galaxy, and that means customization and extra features, all for a fair price. Custom PCB, custom cooling, custom bracket, HDMI output, black DVI+backplate heck it even packs 1024MB of memory to play around with for roughly the same money as a 512MB model. All fairly impressive really.
Galaxy GeForce 9800 GTX+ 512MB review
Galaxy GeForce 9800GTX PLUS test - Galaxy recently released this product, custom PCB, custom cooling, custom bracket, HDMI output, black DVI and backplate. I sometimes wonder why a small company consistently can push out striking products like that and the bigger AIBs mainly focus on the reference design.
Galaxy Geforce 8800 GT HDMI w/ Xtreme Tuner
Our initial review of this product was taken offline as we received an early version of the product. This early version had a "beta" cooler on it that made a truck-load of noise. Galaxy claimed to have a new cooler ready and asked if if we could revise the review based on the new and final cooler. And therefore we have updated this initial article to revision 2; based on new facts with the final cooling solution implemented. And it sure is a lot better.
