An AMD Athlon 64 X2 system would have been more memory sensitive, but its overall performance is smaller, which is why we decided to stay with the Intel Core 2 Duo system.

    mmm yours memory tests don't convince me. You should run, for example, Winrar AND Lame IN PARALLEL/SIMULTANEOUS (i.e multitasking), otherwise, caches don't are flushed (and it's when dual channel really is important). Note that it's not a superflous situation; under normal use a system commonly have several huge memory applications run concurrently (word, browser whith a lot of tabs open, anti-virus, etc. )

    I doubt anyone from Tom's will see this comment on such an old article, but it would have been interesting to see Single-vs.-Dual channel memory using an AMD processor. Since Tom's like Intel, the new Core i7's would also be beneficial. The point is, the article acknowledges the Core 2's have a tremendous amount of L2 cache to combat FSB (and consequently Memory) latencies. How is the comparison with an AMD or nwe Core i7 where there is NO FSB and the L2 Cache is significantly reduce? I would imagine this is where dual/tripple-channel shows is mustard. I hope we see a single vs. dual vs. triple channel comparison soon.

    Won't it be different when using a AMD processor with Memory Controller inside CPU.

    My Windows Experience Index 3D gaming graphics score goes up from 3.8 to 5.1 when I switch from dual channel to single channel. This makes absolutely no sense. I thought dual channel was supposed to be better than single channel. Can anyone explain this?

    I seriously doubt that this score is accurate. I am using the built in graphics controller on the motherboard which is an AMD 760G chipset (ATI HD 3000 or 3200 I think). I've used Radeon HD 5450 video cards on similar systems and they give me a score of 5.4. How can a built in graphics controller give me a 5.1?

    because if you used 2 different memory chips both will run at the speed of the lowest memory chip when you activate dual channel in your motherboard

    That earlier article on Processors doesn't work, so I'll add this:
    Intel HyperThreading - leading to the "H T" on the 'Intel Inside' sticker of computers with that 875p chipset and a single core Pentium 4 processor.
    It equals simulated dual core tech.
    Some Core processors also have HT.
