RAM populating question.

[YOlkie]

Hi Guys,

Not sure if this is the correct place to ask this:

For RAM population, eg: Dual channel, Triple channel, Quad channel, do I take reference from the CPU or the motherboard or both.

Eg:
CPU: ARK | Intel® Xeon® Processor E5-2667 v2 (25M Cache, 3.30 GHz)

# of Memory Channels 4

Does this mean that, performance wise, 4 x 2GB RAM will be better than 1 x 8GB RAM?

How about motherboard? Do I need a "quad channel" motherboard? or no need?

I am relatively new when it comes to this. Can gurus can shed some advice? Or am I getting the whole concept wrong?

Multiple channels in memory are analogous to RAID0 in storage systems. You will have some gain in performance, but don't expect it to double or triple. There are still bottlenecks at areas like your processors, non uniform distribution across the channels, other peripheral wait states and ur storage systems. When you add up altogether, you wouldn't likely get the best case scenario

For troubleshooting purpose, 2 pcs is better than 1.
