Intel® Desktop Board DX79SI

Intel is at it again when it comes to the performance and bandwidth that extreme gamers, digital media creators, and ultimate multitaskers need most. The Intel® Desktop Board DX79SI provides unmatched performance in production and editing, as well as digital media rendering and real-time audio/video preview capabilities. The massive data throughput and support for the Intel® CoreTM i7 processor Extreme Edition runs more applications simultaneously, with less wait time. SuperSpeed USB 3.0, SATA 6.0 Gb/s, quad channel DDR3 memory and full support for AMD CrossfireX* and NVIDIA SLI* technology are just a few of the many features supported on this board.

“As motherboards go, the DX79SI is a surprisingly understated beast.”

Produkt- och prestandainformation


1. Systemresurser och maskinvara (t.ex. PCI och PCI Express*) kräver fysiska minnesadressplatser som kan minska tillgängligt adresserbart systemminne. Detta skulle kunna leda till att en minskning med så mycket som 1 GB eller mer med fysiskt adresserbart minne finns tillgängligt för operativsystemet och programmet, beroende på systemets konfiguration och operativsystemet.

2. Intel® High Definition Audio (Intel® HD Audio) kräver ett system med lämpligt Intel®-chipset och ett moderkort med lämplig codec och nödvändiga drivrutiner installerade. Systemets ljudkvalitet kommer att variera beroende på faktisk implementering, styrenhet, codec, drivrutiner och högtalare.
