<< i am lookin to get a p4 1.9ghz and want to know what the best m/b i could get .
i am not looking to overclock cause i wouldn't know how if i wanted to, so just something thats good out of the box . also i have 512mb of pc133 and wanted to know if i should stick with it or go with ddr 266/333 or rdram ...and is there that big a difference? >>
Is that a northwood P4 (it better be...)? Anyhow, I'd go with the Asus P4S333, which is based on the SiS 645 chipset, which in many (or most) cases outperform the i850 (based on RDRAM). Also, don't put SDRAM in a P4 system (or Athlon, for that matter), it's a performance killer. For memory, OCZ PC2700 offers good performance at a reasonable cost, but Corsair XMS2700 runs at 2-2-2, which would obviously yield greater speed. As for overclocking, that's easy--the BIOS has an option to adjust front side bus speed, increasing it increases the speed of your CPU (the CPU of your system runs at a multiple of the front side bus speed), and you can even increase the core voltage of the CPU (more speed needs more power). If you get a P4, it is highly advisable to overclock, because otherwise much cheaper Athlons will be crushing your system in terms of performance, and no one likes to spend extra for a slower product.
