My board has a K8M800 chipset, with an advertised 800mhz HTT/FSB and a 533Mhz North-South bridge. Overclocked from 200 to 225 gives me a 900Mhz HTT/FSB and a 600Mhz North-South bridge, and it runs fine.
I found a setting in the bios, LDT to AGP Lokar that was set to 800, but had an option for 1000, so of course I had to see what that did. I booted into windows, and all of a sudden I had a 1125 HTT/FSB, but still had a crappy 600Mhz North-South bridge.
Is running my 800Mhz chipset at 1125Mhz a bad idea? Just wondering..
