DDR3 Pins

post #1 of 10
Thread Starter 
Does anyone know if DDR3 uses the same number of pins as DDR2? As i'm wondering what motherboards might support DDR3 already with a simple Bios update. It can't be just P35 Chipsets...can it?

I'm 90% sure that you won't be able to use DDR3 on any of the current boards out.

I'll third that - they will not work on boards out now unless specified they support DDR3

I believe they use the same number of pins but a different slot tab. DDR3 will not fit into DDR2 slots. DDR3 is not just a voltage change so the memory controller must be designed to handle them. A BIOS update won't do a thing.

But current boards don't specify Penryn support but they should do..

Yeah Penryn supports DDR2 as well (AFAIK), since DDR2 and DDR3 doesn't run at different memory speeds yet. Penryn only requires a 1333MHz FSB

I was right... both use 240-pins but have a different slot. It will not work. End of discussion.

Yes, just it's backwards. So you could "accidentally" put a DDR2 DIMM into a DDR3 slot and vise versa.

It's not just backwards... the spacing is different. DDR2's notch is closer to the middle than DDR3.
