Diamond HD4890 XOC Pixelized

by MrK · April 11, 2009

AMD/ATI launched HD4890 in two flavors. One is the stock HD4890 with core clock at 850Mhz while another variant is HD4890 OC with at least 900 MHz Core frequency and higher memory clocks than 3900Mhz. AMD/ATi’s partners are free to offer higher clocked products. That is what Diamond did with their overclocked HD4890. They call it the HD4890 XOC (4200 MHz Effective) and it comes with 1GB of GDDR5 memory. It employs two DVI connectors for video output capabilities. It features AMD/ATI’s reference cooler which exhausts air out of the case.
