Re: CTPCI and 33 MHz boards

There are some benchs on ctpci.atari.org, at the end there are a comparison between 33 and 47 at the same CPU frequency, there are no big difference. The 1st impact when you overclock or underclock PCI BUS is for run the VGA BIOS X86, and blocks transfers to the board (masked here in background because DMA is used, => 1500 MB/S ???)
Underclock/Overclock PCI BUS is now possible with the CTCM and not only my own clock generator.
