Difference between dual channel ram and normal ram?

[N1sh]

Just want to find out if there is a major performace difference between 2 one gig sticks of dual channel ram and 2 normal one gig sticks of ram.

Thanx for any help guys

Dual Channel RAM is just normal RAM. The difference is that you put two sticks of dual channel RAM in the same channel and you're supposed to get some performance increase, but this has been shown to be less than 1% and not worth it.

It improves the transfer of data I think. Something to do with pipelining maybe. But after all your system bus can only carry so much.

5% increase in most cases

Well for me at least

Yip very low performance boost in games you won't even realize a difference. Which is sad really since DDR2 ram is so dirt cheap you can easily afford 2 ram sticks for dual channel.

I think I covered this in the Hardware and Software FAQ.

Surely the performance is dependent on the MB design?

Mainframes have used dual port memory for ever and one of the performance benefits is that I/O can take place concurrently with CPU access, but I'm not sure whether this technique is applicable at the PC level yet.
