The advantage of DDR2 memory architecture could be revealed after FSB upgraded from 800MHz to 1066MHz. It's benefit from FSB1066 and DDR2 533 reach an synchronization on data transmitting.
MSI 925XE Neo Platinum motherboard has adopted Intel? 925XE and ICH6R chipset, which supports LGA775 Pentium? 4 Prescott processor with FSB 1066MHz or 800MHz, dual channel DDR2 533 memory architecture, and PCI Express x16 graphics interface. The ICH6R chip supports not only PCI Express x1 expansion slots and 7.1 High Definition Audio, but also Intel? Matrix Storage Technology. Intel? Matrix Storage Technology combines the advantages of conventional RAID 0 and RAID1, composing Matrix RAID with only two hard drives. Protect your important data with RAID 1 and increase your productivity with performance of RAID 0.
The technical expertise of MSI engineering team created 925XE Neo Platinum supporting dual channel DDR2 600, 667 and 710 with unlocked Intel processor. High flexibility of IDE devices was brought by additional VIA RAID controller and two extra IDE interface. User can configure as RAID 0, 1, 0+1 or JBOD.

Overclock your CPU FSB (Front Side Bus) with lowest CPU Ratio from MSI latest feature "CPU Ratio Unlock", exploit margin of your CPU. Because the memory bus will be overclocked synchronously with FSB, memory performance will be enhanced at mean time. With the function of "CPU Ratio Unlock" and qualified memory module, overclock ordinary FSB800 P4 processor to FSB1066 is absolutely possible.
The standard bandwidth of DDR2 533 memory architecture is 8.53GB/sec with dual channel. When we simultaneous raise CPU FSB from 200 to 266 and DDR2 533 to DDR2 710, the memory bandwidth will be extended to 11.4GB/sec with dual channel. We can see obvious 33% improvement is achieved.
MSI unveiled "CPU Ratio Unlock" function on CellMenu of latest BIOS of high-end LGA775 platform, including 915P Neo2 Platinum, 915G Neo2 Platinum and 925X Neo Platinum. After CPU Ratio Unlock is enabled, CPU ratio could be set to 14X instead of original setting. While the CPU ratio is set to lowest, user have higher margin to overclock FSB and memory frequency.
CPU ratio is locked in retailed version Intel CPU, to avoid profiteer remarks CPU from original frequency. But overclocking of FSB will be limited by this boundary. Higher frequency of Pentium 4 processor usually represents better possibility for overclocking.
