I'm running Fedora Core 5.
I have a plain vanilla 2.8Ghz P4 Intel motherboard with 4 DIMM slots.
I currently have 1 DIMM of 512M DDR 3200 memory. I purchased a second
DIMM of the same 3200 memory hoping to upgrade the memory.
When I install the second DIMM, the BIOS properly recognizes it,
however, FC5 won't boot properly. The boot time takes forever. The
bootup is sitting in "Starting UDEV" for a very long time.
I believe the new memory DIMM is okay, I can use either memory DIMM
properly, however, attempting to use both causes a problem.
I'm stumped as to what could possibly be wrong.
I don't use the stock FC5 kernel, but instead have compiled my own
2.6.18-1 kernel. I have the Memory Split option set to the default
3G/1G user/kernel split.
I don't know if this is the correct list to ask this question. Does
anyone have any suggestions?

Yeap, check the voltage settings and also check the CAS between the two
DIMMs. This is Column Access latency, some are faster than others, that
can throw the timings out too.
Finally, modern DIMMs are designed to be paired to run Dual Channel mode
for faster front side bus speeds. You've likely enabled dual channel
mode, make sure that the DIMMs are where they're meant to be. I see
PC3200 = DDR400, which means they should handle 800Mhz FSB, which is the
max FSB speed of your proc.
