Soltek sent us word of their success in running a Pentium 4 1.7GHz on an 200MHz (800MHz QDR) front-side bus. Here's a quote from what they had to say - This BIOS can fix AGP clock at 66Mhz PCI clock at 33Mhz when overclocking; by this way, you can get a more stable system. Our RD team have sucessfully overclock this mainboard to 200Mhz (200 x 4 = 800Mhz FSB)! This is certainly a great news for overclockers; however, please note that now most CPUs have been locked, it is very difficult to find an unlocked CPU.
