16GB vs 32GB DDR3, Dual Channel vs Quad Channel

post #1 of 4
Thread Starter 
I have this motherboard:
http://www.gigabyte.com/products/product-page.aspx?pid=3973#sp

It handles:
4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory
Dual channel memory architecture
Support for DDR3 2133/1866/1600/1333/1066 MHz memory modules


I would like to purchase 32GB for virtualization needs, however I am hearing that a stick of 8GB of DDR3 will always be slower than 4GB of DDR3. (Assuming that both sticks are the same specs otherwise). Is this true? And if so, why? The sticks themselves are the exact same physical size (aren't they?), and with SSD drives they tend to increase in read/write speeds the higher the storage that you purchase.

So that's my first question. Second question is should I purchase my 4 sticks of RAM in Dual Channel for this motherboard or will I find an increase in speed if I purchase 4 sticks of RAM in Quad Channel (and purchase a new motherboard to handle Quad Channel). I'm pretty much clueless when it comes to buying good RAM so any advice on timings, virtualization usage, gaming usage, and future proofing would be greatly appreciated.

Thanks!

The move to LGA2011 is really expensive if all you're looking for is quad channel RAM...

How many VMs do you plan on running anyway?
The difference in speed will be negligible between capacities.

Considering Laptops are becoming standard with 16gb, and the shift towards next gen on the horizon, I think it's silly to go with less than 16gb, 24 or 32 make sense assuming you can afford it... I say go for 32!

...laptops are NOT coming with 16GB standard.

Next gen what? Consumer memory requirements have barely changed in the last 5 years except for enterprise server infrastructure.

OP, how much are you virtualizing? What's the memory usage today? Is your CPU up to task?
