Just setup my D510MO with two Mushkin Silverline 2GB PC2-5300 5-5-5-15 1.8v sticks. It booted up fine and I was able to install WHS and fiddle with it for about 30 minutes before it hard hung. Now the thing won't boot or post with both sticks installed. Using either stick in either slot works fine.
Checking the BIOS settings it had the incorrect settings for the memory; it had 8-8-8-24 or something along those lines. Changing it to manual and setting the right settings, 5-5-5-15, caused it to not boot/post.
I updated the BIOS from version 0175 to 0308 but that didn't fix the issue. Now it automatically picks the right settings for the memory but still won't boot with both sticks installed.
What do I need to need to do to get both working with this motherboard?
I pulled the battery and held the power button for ~30 seconds and now it will boot with both sticks of memory.
Lets see if it will remain stable now...
