Question : Problem: RAM - high or low density?

I am looking to put a 512MB DIMM in my ASUS CUV4X-E
I am located in Canada, and I don't want to bring the RAM across the border, so I am trying to determine whether the board supports high-density chips, as they are more inexpensive!
Crucial.com says these chips will work:
512MB — CT64M64S4D7E SDRAM, PC133 • CL=2 • Unbuffered • Non-parity • 133MHz • 3.3V • 64Meg x 64      
512MB — CT64M64S4D75 SDRAM, PC133 • CL=3 • Unbuffered • Non-parity • 133MHz • 3.3V • 64Meg x 64
and some other sites I have tried tell me that the board supports 16x8 or 32x8 configurations with a CAS latency of 2.
My local parts store has 2 different modules, low or high density - does any of the info above tell me if this board will support HD modules?
Thanks!

Answer : Problem: RAM - high or low density?

I would ask your local parts store if the HD memory he sells will work with your MB. Most memory manufacturers will specify what chipsets are compatible.

This is an interesting website that might have some info:
