Sapphire HD4850 Review



The next step in configuring the Sapphire HD4850 is to open up the Catalyst Control Center; using this application, you will be able to control just every setting that is able to be changed on the video card. When you first start it up, you will have an option to choose if you want to use the Basic view or the Advanced view of the Catalyst Control Center. I chose to use the Advanced view, this will allow you to change more settings. When you go to click the next button, a popup will show up letting you know that if you want to change back to the basic view at a later time, you will be able to do so. After you accept the popup, Catalyst Control Center will start up and start on the Welcome screen, this is where you are able to view and use useful online links that will take to to an update checker, allow you to contact customer support, join ATI's Folding At Home team, as well as other things. Under the Information Center tab, you will be able to view both hardware as well as software information about the graphical end of your computer. This can come in handy if you needed to know which installation of Catalyst Control Center and what drivers you currently have installed.

















The next tab that I want to take a look at is the Display Manager tab, this is where you are going to be able to see how many displays you have connected to your computer as well as what they are going to display. Not only are you able to choose what they are going to be able to display, you are able to change what the resolution for each display will be set at, what the refresh rate is going to be, and if you want the color quality to be 32 bit or 16 bit. The next tab that on the agenda is the Digital Panel, the first page that I want to look at under here is the Avivo Color page, here you are able to change the hue, saturation and the temperature of the color that is going to be displayed. Under the Attributes page, you are going to be able to see different information about the displays that are connected to the HD4850 such as the maximum resolution the display is able to use. You are also able to enable GPU scaling and set the options for that here. The final page under the Digital Panel is called HDTV Support, this is where you are able to chose the different HD formats to use when a HDTV is connected to your HD4850.




The final section of the Catalyst Control Center that I want to look at is the ATI Overdrive page. This page is locked after you first install the program and the drivers. When you unlock this page, you are unlocking the ability to overclock your video card's core and memory clockspeeds. You are able to use a slider bar to select what the settings are you wish to use as far as the clock speeds go, there is a maximum of 1200MHz for the memory and 700MHz for the core. You are also able to use an Auto Tune feature that will do the overclocking and testing for stability for you. There are two gauges on the side that show you your GPU temperature and your GPU activity.
