1) Bank A in DIMM1 - System reboots 15 - 45 seconds after Windows loads.

2) Bank B in DIMM1 - System constantly reboots

3) Bank A in DIMM2 - System seems stable

4) Bank B in DIMM2 - System reboots every 2 -3 minutes after Windows loads

5) Bank A in DIMM3 - System stable

7) Bank A in DIMM1 & Bank B in DIMM2 - System will not boot

Wow, well I?m trying to understand what you telling me?are you saying that your system is not working properly when your ram is in different configurations? If I am understanding correctly and your system is working under this setting:

5) Bank A in DIMM3 - System stable

6) Bank B in DIMM3 - System stable


Why not run it that way?

If it is only running when in a specific bank, that indicates a bad board. It shows that the ram is working. try the ram in another machine and I am sure that it will work. Sounds like a bad board.
