? DDR2, DDR1, and Dual Channel - What's the difference
I see memory being advertised as DDR2 now as well as DDR1, someone told
me that Dual Channel Memory is the same as DDR2? Is that so? I also seen that PC3200 does not come in "DDR2" but does come in "dual channel". Can anyone explain the differences?

? DDR2, DDR1, and Dual Channel - What's the difference
DDR1 is an older standard for RAM sticks that was used up until about a year
ago in motherboards routinely. DDR2 is the current standard and uses a different socket and number of pins than DDR1 and so is NOT backward compatible with it. DDR2 also comes in faster speeds than DDR1. Now, Dual Channel is a system used by motherboards of the last few years, for BOTH DDR1 and DDR2, to double the data transmission rate by using two IDENTICAL RAM sticks in a pair of specified slots on the motherboard. -- DaveW ---------------- "Sam" wrote in message news:0ABnh.552074$1T2.393550@pd7urf2no...
