Memory installation problem

[Guest]

I bought another memory stick( pc2700 512 ddr raam Centon). and I went to
install it in. After I turned my comp on it blue screened and had a message
on the bottom which said (Beggining Physical dump). I have a ASRock K7VM4
mobo. when I removed the memory my comp turned on correctly. I tested the
memory by placing one stick only in the slot and it booted up. so both sticks
work. Then I put them in both and in the begining when it boots up and does
the memory check it read it as 10............ so it read them both and after
the win xp logo popped up it blue screened again. it keeps telling me
sometype of error and then it says begining physical dump. the comp doesnt
seem to boot up when both sticks are in. is there anything in the bios or
anywhere else that I have to do.

One stick is incompatible with the other.

Memory must be of identical specification: Speed, etc... and in some
instances of same capacity.

Here are some examples of memory specifications.
• Un-Buffered DDR SDRAM
• DDR266 (PC2100)
• 2.5 Volt
• 184-pin

• Un-Buffered DDR SDRAM
• DDR400 (PC3200)
• 2.5 Volt
• 184-pin
