Can DDR2 memory be used on DDR3 motherboards?

[MplsBob]

Am I correct in my understanding that DDR2 memory can be used on DDR3 motherboards?

As of right now, all mobos that support DDR3 will also have DDR2 slots, but the two slots aren't interchangeable despite having the same pincount (IIRC)

only if it has DDR2 slots. They are physically different.

The slots are both electrically different and mechanically different (the notch is in a different location). As you say, the only way to have support for both types is to have two separate sets of slots.

The chipsets can support both types, but the motherboard only supports which ever one it has slots for. DDR2 and DDR3 do not use the same slots.

different key just like ddr->ddr2

Isn't DDR2 only like a year and a half old? Why didn't they just stick with DDR?

That's what I'd like to know also.
BTW, I didn't they should have cut production of the AMC Pacer either. :laugh:

Bandwidth. Thats why. DDR3 speeds will be able to ramp higher with less voltage, however I don't think most systems
for at least a year will be able to make the most of it. I am quite happy with my DDR-800.

As with ddr2, ddr3 will eventually provide a legitimate benefit but for now because the latencies are so high its not much faster then ddr2, it will probably take a year or so for it to gain enough speed and drop enough in price that it really becomes relevant.

I think Intel made the push as their platforms needed the bandwidth and AMD followed after prices went down.

Blain, I'm still laughing. Actually I preferred the Hornet to the Pacer, (Smile)!!
