I have seen a lot of reviews and even looked at the mobo manual for the ASUS 815 board, but I am still confused on what ratio the AGP is running. On the ABIT and ASUS I've only ever seen the CPU/SDRAM/PCI ratio, but no word of what the AGP is running. Any info is much appreciated. Thanks in advance.

The I815 chipset automatically runs a 1/2 AGP ratio with bus speeds at 133MHz and above, below that it runs 2/3 like the BX chipset. This means if if run a 150MHz FBS the AGP port will be running at 75MHz. Remember that the 1/4 ratio PCI bus gets overclocked as well running at 37.5 MHz with a 150MHz FBS
