Canon FS11

At the moment we saw it, we knew that this was the love at first sight. Canon FS11 is in true sense of word, compact digital camcorder with innovative and attractive functions, futuristic design and 16GB of memory for storing recorded video material. Canon Company revived camcorder market with FS11 model. It uses built-in memory instead of MiniDV tape or CD/DVD media. Canon FS11, beside low power consumption and small dimensions, brings completely new approach in recording home videos. ...

 

Creative Aurvana X-Fi

We prepared a little surprise for you from Creative, and it is not mp3 player nor is sound card, neither one of products Creative is best known. For this test we got headphones attended primary for all air plane passengers, but also for all those who love great and crystal clear sound.  Aurvana X-Fi is their name and it’s obvious that name originate from words Audio and Nirvana. Well, name does tell it all. ...

 

Gigabyte GA-EP45-DS3R

This time we have tested a middle-lower class motherboard but nevertheless an interesting model, Gigabyte GA-EP45-DS3R. Gigabyte was always, at least when it’s comes to DS3 series of motherboards, known for simplicity and real good production quality. ...

 

Logitech G51

Logitech G51 speakers were the first with prefix “G” (G as a short from gamer). Sound, as one of important component of any game, should be the best as possible, so engineers from Logitech did their best to satisfy expectations of most demanding users with this model. ...

 

Olympus E-520

Olympus E-520 is considered as ticket to D-SLR world and its price speaks for itself. When you take this model into your hands you really got the feeling that you are holding a quality pro model that can accomplish a lot. For testing purposes we’ve got two additional lenses: Zuiko Digital ED 50 mm Macro and telephoto lens Zuiko Digital 50-200mm (equivalent of standard 100-400mm). Olympus E-520 is available in two variants: kit with zoom lens Olympus Digital 14-42mm (we got this one also on test) and variant without this lens (just body). ...

CrossFire overclocking
Few tips
Youth elixir
One of the ways to increase the level of 3D performances of your computer without any additional investments is overclocking of graphic card. In this case, we will deal with overclocking of graphic cards with ATI chips. The tool which we need is called ATI Tool. Via ATI Tool beside alternating of operating frequencies of the chip and memory on graphic card, it is possible to test overclocked card using Artifact Tester which will help you to see if settled frequencies are too high, and if they are, on 3D model the artifact will appear i.e. „cracking“ of polygon and textures. Artifact Tester is not confident that much so it is better to initiate some 3DMark test after this one, or some of more demanding 3D games. The most important thing for good overclock is patience, so it’s better to shift chip frequencies and memories step by step of 5-10 MHz.

After each frequency increasing, mandatory test it with Artifact Tester and 3DMark. In case if you shift the slider more times for 5-10 MHz and frequency is higher than nominal for 50-70 MHz, and 3DMark and Artifact Tester don’t send message on faults, try just in case some of demanding games in order to verify stability of overclocked card, so if artifact occurs in games, return to ATI Tool and decrease frequencies for 5-10MHz. Also very important option which ATI Tool has is “Fan Control” which is used to set fan rotations for particular temperature, therefore reducing noise in the computer when there are no 3D applications running, but also when you start some game or benchmark program pay attention that number of rotations must be higher because graphic card might get overheated otherwise. Simply use Fan Control and find balance by yourself. Also, ATI Tool has an option Voltage Adjustment where you can increase graphic chip, memory and memory buffer voltage. This option is very useful for reaching higher frequencies, although it’s recommendable only for experts, because excessive voltage can cause permanent card damage.

On the market, there are lot of companies involved in cooling of various components, which also include graphic cards, and in case if you buy cooler made by ArcticCooling company, Zalman or CoolerMaster, you will get additional space for 10-30 MHz on the frequency you set with default cooler. Naturally, if you want to extract maximum out of chip of your cards, there are solutions with water cooling like “Sub-Zero” or even liquid nitrogen packages intended for graphic cards, but these solutions are extremely expensive. But, as we mentioned at the very beginning of this text: “without any investments”, so we will stick to that, and it means pure overclocking without extra cooling. Given we got acquainted the Tool, it’s time to do some job.
