yeah machina.. thats why I have been preferring the x800 pro bios's as they are agp. Im just trying to figure out how to decipher the bios' now.
As far as the latencies of the different DDR's, I have looked into different bios' memory settings and they are mostly using the same default 1.5ns setting. Even our bios. There are a lot of individual memory speed settings that vary but not much. One of my favorite bios settings are under ours except mem/core and I have been working with that one alot.
I think the x800 mobility bios is our best chance as I will be able to cross reference the code and see the similarities. There I will find the code for the display port settings and AGP/PCI-E. Then I will try to make a "hacked" bios by pulling select portions of the 12 pipe bios' over and see if it opens the pipes..
Still have some experimenting to do... Still wishing for the MRX800 bios... Then some damage will be done
