Latest processor technology
The PRL-DL motherboard supports both Intel
®
Xeon™ processors via dual
604-pin surface mount ZIF sockets. The processor features the Intel
®
NetBurst™ micro-architecture that includes hyper-pipelined technology, a
rapid execution engine, a 533MHz or a 400MHz system bus, and an
execution trace cache to offer a significant increase in performance. See
page 2-4 for more information.
DDR memory support
Employing the Double Data Rate (DDR) memory technology, the PRL-DL
