I've got a DFi Lanparty Ultra D flashed to SLI,

the probelm I'm having is that I want to add mismatched memory, but it won't boot unless the memory is placed in slot 2 and 4. this is maddening to say the least because i owuld like to run a few VM's (windows 7 primarily) and the lack of memory is really killing me.

anyone know how to use more than two ram slots on this board?
 
A little more info would be helpful........
What memory (link please).

Anyway.....
SPD timings and voltage requirements are read from the module in the slot closest to the memory controller. If no stick, then slot 2.

I would assume that the SPD being read and applied to both (mixed) modules is incorrect for the one farthest from the memory controller.

Switch the sticks.

DFI's (due to their excellent overclockability) are pretty pickey about memory, so good luck.

Sorry for the late response.

they're a 1gb generic pc3200. not sure about the clocks or timing at this point.
 
They don't need to be exactly correct but it helps if they're similar. Install each pair of sticks at a time, and see where auto-timings land in BIOS and Windows. (You may need to clear CMOS) Determine the lesser pair, then manually set timings and voltages according to those sticks. Shut off the system and install the other pair of sticks.

Basically you want to set the BIOS to slower sticks. If it's the other way around, the slower sticks won't keep up with the setting and refuse to boot.

This of course assumes that all sticks are functional, and work with the board if installed individually.
