NV45 & R423, PCI Express Testing
 

Recently, Boston sent us a rather powerful Dual 3.4GHz Xeon (Nocona) workstation on the new Tumwater chipset, with DDR-II, PCI Express and U320 SCSI. The Nocona core is basically a Prescott core with a 64-Bit Extended Memory bolt on. Considering we are running in 32-Bit and these Xeons don't have any Level 3 cache, this can be considered to be a dual Pentium 4 Prescott system hopefully offering a bit more power than our 3200+ Athlon 64.
