Okay so... As I told I got two 7457 cpus rated for 1.267GHz and one 7448 rated for 1,7GHz. As I again already told you the 7448 is planned to go to my DLSD and the two 7457 into the MDD I will go pick up at the end of the week. I already downloaded the PowerLogix & Newertech G4 Enabler to patch the MDD to accept the new 7457s. Any other ideas? Will the enabler work on the MDD?
