I am running Windows XP 32 bit edition on one HDD, and I recently installed Vista Ultimate 64 on another HDD (after some problems with an ACPI compliant error that I solved by removing one of my two sticks of RAM). Please take a look at my configuration and tell me how I can get Vista to boot properly with both sticks of RAM. The situation is thus, with my RAM: I bought a Zalman fan that has copper fins to reduce heat. The fins stick out over the first slot of RAM (the A1 slot for channel pairing) and I instead opted to put my first stick of RAM in the B1 channel. My other stick is in the B2 slot, which is the last slot on the board. That might be the issue, but I figured I would bring this up. Here is my load out:
AMD Athlon 65 X2 6400+ Dual Core AM2 slot

2x Nvidia GeForce 9600 GT series SLI
