Weird FSB experience lol

[Jgtdragon]

Today, I was kinda bored so I decided to run the Radeon Ark Demo and was mad of its lagging performance. So I enabled the agp from 1x to 2x and up my FSB by 1 to 101x10. It should be 1010 Mhz, but in WcpuID says its 1015. WTF! lol
I ran some benchmark in Sandra2000. To my suprise I have surpassed the 1Ghz T-Birdy with my old classic( before I was quite behind). The gain in FPU was amazing considering only 1 FSB increase. Weird Eh? I heard that 2x on Radeon was tough on Ka7, but not for me. All I did is reinstall the agp driver in turbo, but 4x I can't get into Windows.
