I'm building another pc for a friend. The pc has my old Radeon SDR in it. While doing some overclocking I noticed that the AGP divider in bios was set to 1/1 The thing is, with FSB @112MHz the AGP was also running at the same frequency. I could not believe it so I got hold of sisoft sandra and surely it was 112MHz. Not happy I left the machine running the whole night looping 3Dmark (I had the fire dept. phone number handy, just in case) and the morning after it was still running. Now that is an amazing tolerance, from the original speed of 66Mhz to 112! I invented AGP 3X mode!
