CM2x1048-6400C4 and P5B Deluxe - can't POST 4GB

I can POST fine with 3GB in my P5B Deluxe, but as soon as I add the 4th 1GB DIMM I get nothing, no beeps, no video and graphics fan on full speed. It's not the DIMM, because I've swapped the 3rd and 4th DIMMs and it boots fine with 3 no matter which is left out. It's also not the slot, because I've booted successfully with various slots empty.

 

I have the BIOS set to DDR2-800MHz (tried 667, didn't help), with vDIMM at 2.0v (2.1 didn't help), and timings at 4-4-4-12 (auto didn't help).

 

Any ideas how to get the 4th DIMM working?

 

Thanks!

Please test the modules one at a time to make sure you don't have a failing module, if they all work one or two up there is some other problem. What is the complete system configuration?
