1066 RAM on M4N78 Pro AM3 720BE

[pplapeu]

This is a follow up to the other thread from a few days ago with "1200 MHz Limitations" in the title I posted the last few days.

With nothing other than a BIOS changed to 1066 you can see that the Asus m4N78 Pro loosened up the timings , if you refer to the older thread.

HOWEVER - - I am registering all four DIMM slots!!!
That was a concern for me.

I want to thank all the members who helped clear things up for me.

:)

I do not get why SANDRA nymbers the banks as you see but below is a direct paste from a hardware info run in SANDRA.
