Oh, a tough guy, eh? :-) Try:

Faster, yes. NOT 2x because - http://www.cs.swan.ac.uk/~csneal/HPM/memory.html

From a Google - http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=interleaved+memory+performance&btnG=Google+Search and if 66,000 hits won't convince you...

>I checked out the hits. Inconclusive. I'm thinking my co-worker saw an article and has jumped to a conclusion.

>>I'll give it a try, Evan. Google on "memory interleave". If supported on the motherboard, this technique improves access speed, effectively 2X. I don't know whether it applies to current hardware.

>>>A guy at work claims that having two 256meg RAM chips are faster than having 1 512meg chip. I can't find proof either way on this. Can anyone point me to an answer?
