Results, Sync Dual Channel VS Async Dual Channel VS Single Channel mem.

post #1 of 6
Thread Starter 
For those who are curious on the performance differences between these three memory configurations I have tested them using AIDA64 on my setup:

Motherboard: Asus P5Q Pro Turbo
CPU: Q9650@3870MHz
Memory: Crucial Ballistix 4x2GB DDR2 PC6400 4-4-4-12 2.0v@1033MHz 5-5-5-15 2.0v



AIDA64 results:

2x2GB - Sync Dual Channel
READ: 8815 MB/s
Write: 9138 MB/s
Copy: 9142 MB/s
Latency: 58.8 ns


3x2GB - Async Dual Channel
READ: 8685 MB/s
Write: 9112 MB/s
Copy: 8463 MB/s
Latency: 60.6 ns



2x2GB Single Channel
READ: 7289 MB/s
Write: 8087 MB/s
Copy: 6987 MB/s
Latency: 63.6 ns

Would you be willing to throw up a real-world benchmark?

A game or something? In a real world benchmark the differences will most likely be even smaller...

Yeah, I want to see (yet again) how single channel vs dual channel is very slight in real-world scenarios. There are a lot of misconceptions about that.

Okey... Maybe I will benchmark a few games or something... The reason I did this in the first place was beacuse my Asus P5Q Pro Turbo has issues overclocking with 4x2GB RAM. However, it overclocked very nicely with 3x2GB. So I wanted to see what performance differences there was between the regular Sync Dual channel config and the Async Dual channel setup.

And just because I was curious I throwed in some results from my setup running with Single channel config aswell...
