Page 5 - Movies and Overclocking

 Media PlaybackA much forgotten item in reviews nowadays is of course multimedia/movie playback. In an old review; I believe it was GeForce3, I stated that NVIDIA should take a good look at ATI when talking about dual monitor setups and movie playback through the S-Video connector. Well, NVIDIA did that and more ever since they released the GeForce4 family. Seriously, movie playback / video-output has improved tremendously over previous generations. I can start stories about what and why this has changed, the new driver 'tweaks' bob and weave interlacing etc ... But basically it's all way too much blah blah.

Images taken with GeForce FX from the movie: Red Dragon - JPEG compression makes it a bit fuzzy.

Basically, all you need to know is that playback is now truly at a level that can compare equally with arch rival, ATI's Radeon series. This is the stuff where the 5500 real value is.

Performance & Overclocking
Before we dive into an extensive series of tests, we need to discuss overclocking. With most videocards, we can do some easy tricks to boost the overall performance a little. It's called overclocking the videocard, and by increasing the frequency of the videocards memory and gpu we can make the videocard increase it's calculation clock cycles per second. It sounds hard but it really can be done in less then a few minutes. I always tend to recommend to novice users and beginners not to increase the frequency any higher then 5-10% of the core and memory clock. Example: If your card would run at 300 MHz then I suggest you don't increase the frequency any higher than 330 MHz.

More advanced users push the frequency often way higher. Usually when memory starts to show white dots 'snow' you should go down 10 MHz and leave it at that. The core can be somewhat different. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. I recommend that you back down at least 15 MHz from the moment you notice an artifact. Look carefully and observe well.

All in all .. do it at your own risk. Overclocking your card too fast or constantly to its limit might damage your card and it's not covered by your warranty.

You will benefit from overclocking the most with a product that is limited or you may called it 'tuned down'. We know that this graphics core is often limited by tact frequency or bandwidth limitation, therefore by increasing the memory and core frequency we should be able to witness some higher performance results. A simple trick to get some more bang for your bucks.

The GeForce FX 5500 from Point of View with 128-bit 256 MB DDR memory runs at default 270 MHz for the core and 400 MHz (2x200) for it's memory. The 5500 was a marginal  overclocker with 280 MHz as core frequency and again 420 MHz for it's memory. This card is not a significant overclocker at all.

Overclocking a card like the GeForce FX series is a tricky task as NVIDIA has a built-in SAFE feature. If the core reaches a certain temperature threshold it will automatically lower the clock speed to prevent the GPU from overheating. It's a nice feature yet will make overclocking a tad harder to do.

 Test system
All tests where made in 32 bit colors in resolutions ranging from 800x600 pixels up-to the Godfather of all gaming resolutions, the 1600x1200 several performance/quality settings
