nForce3 250 Chipset Overclocking : Article

Quote: Since the introduction of the AMD Athlon 64 processor the overclocking community has, as ever, been keen to see just how far these fast processors will go. Progress has been slow and frustrating as both the VIA K8T800 and the nForce3 150 chipsets do not lock the PCI bus. This means that increasing the effective front side bus frequency affects not only the CPU and main memory, but also any peripherals connected to the PCI bus, since it's derived from that CPU driven frequency, itself derived from the HTT clock. As most onboard RAID controllers are on the PCI bus and nearly all SATA hard drive connections are via the RAID controller, increasing the front side bus speed can soon cause catastrophic hard drive failures. It seems that most AMD Athlon 64 owners are only able to increase the stock 200 MHz Front side bus a mere 10 to 20 MHz before problems start to occur.
