1 Stick vs 2 Sticks

post #1 of 10
Thread Starter 
What kind of performance difference am I looking at with 1 stick of 4GB vs 2 sticks of 2GB each? Speeds and specs are the same outside of size.

If I remember correctly you always want to go for one stick over 2 for overclocking purposes. However you won't get the added benefit of dual channel with only 1 stick

No. 2 sticks really won't affect your overclock over 1 (only until you go to 4 sticks does it start to do something to overclocking)
Also, dual channel can be a huge benefit/difference in everything you do thanks to the doubled bandwidth, you do indeed want to go with 2 sticks no matter what. I would take dual channel over overclocking to 4Ghz by all means.

What would the doubled bandwidth be beneficial to?

Everything.
Dual channel will give you snappier boot times, better OS response, more snappiness, increased performance in everything, even in real world apps - over single chnanel.

This is sort of true, but the performance increase is very small. You won't notice it unless you're benching or measuring frames.

Nah, the performance increase is pretty big and noticeable. At least to me and all my friends who I've told to rearrange their RAM to run proper dual channel. Only in a very few tasks it would be irrelevant.

Or not, provide solid benchmarks and the numbers are only a few hundred MB/sec to 1 GB/sec difference. Kind of low when you consider that each stick of DDR3 1600 is rated to do 12.8 GB/s each..

Most AM3 bench around that when using two channels..

I would never run in single channel except for testing purposes. Not because it's bad or anything but because you are losing free performance.

If you are planning to buy one 4GB stick and buy another in a month or so I would understand that.
