PRODUCT PICTORIAL & WALKTHROUGH (cont'd)



Moving away from the cooler, we will focus our attention on the connection plate where you will see the standard analog, HDTV/TV out and the DVI display connections. Above the connection you will see the large unrestricted exhaust port for ridding the warm air directly out of your case and therefore reducing any contribution to internal case temperatures.

 

VIDEOCARD OVERCLOCKING


Now, I know that HIS has bundled in their iTurbo software for easy overclocking, but I was looking to get a little more performance out of this videocard other than the iTurbo maximum clock rates of only 500Mhz core and 500Mhz memory when the stock clock rates are 475Mhz core and 490Mhz(980Mhz DDR). I don't consider that real videocard overclocking but rather a warm safe fuzzy increase that will keep everything cozy and secure. But as overclocking enthusiasts, we never just push things faster by such a small margin, we push it to the limit.


To help push this videocard to its maximum, I installed my favorite ATI overclocking utility called ATITool which was created by TechPowerup and can be downloaded HERE. For this review I used the 0.24 beta 2 version available in their forums which has full x800gt support. It is a great utility for simple and effective overclocking without any confusion. It even has a built in utility to find the highest core and memory overclock settings without artifacts. I used this feature and it worked absolutely flawlessly. Just hit the find maximum memory button and allow it to hunt for the highest memory overclock and after that has been found, find the maximum core with the memory overclock in place. It has its' own test rendering video that will come up and if there is an artifact, it will lower the clock until no more artifacts are found. After it is found, save the overclock and you are set.


The onboard memory is comprised of eight 2.0ns 32meg Samsung GDDR3 modules with a theoretical maximum speed of 500Mhz (1000Mhz DDR).


Let's see how it made out:


Here are the results:


Stock Clock Rates: 475Mhz Core / 490Mhz (980Mhz DDR) Memory

Overclocked Clock Rates: 530Mhz Core / 614Mhz (1125Mhz DDR) Memory


Differences: 55Mhz Core / 124Mhz (248 MHz DDR ) Memory


The X800GT overclocking went exceptionally well. As you can see above, the enhanced cooling allowed the core to be pushed and additional 55Mhz and the memory just kept on climbing by 124Mhz. These are not small numbers at all and I am very impressed with the memory seeing memory bandwidth is the key to unlocking your card's performance potential.


As you can see, it did overclock a lot higher than the iTurbo setting which was definitely a plus. The overclocked setting will be included in the benchmarking along with the stock settings for a direct comparison of what this overclock will bring to your gaming system. The moral of the story is overclock your card yourself, don't allow software to dictate your card's limits.

Please keep in mind that results obtained were with driver defaults for testing continuity and are stock configured for image quality rather than speed. With a little driver tweaking, results much higher than seen obtained here could easily be managed.


Testing Methodology


Throughout the testing of this videocard, I will be showing you how this card performed on the system mentioned above using the following programs at 1024x768 and 1280x1024 resolutions at ATI driver defaults (vsync disabled) and also with 6X Antialiasing and 16x Anisotropic Filtering enabled.


All other cards were only tested with no quality settings and only 4X AA enabled in the high quality tests.


Both testing situations will be benchmarked with stock and overclocked settings initialized separately.
