Namely Dual DDR, are these special modules or normal DDR modules?
Do they have to be set in pairs and if so if I install 2x512MB Ram will I have 512 or 1024MB of available Ram?
The hardware scene seams allot more complicated now then in the PII/440BX days, but then again maybe not...

This is how i understand it. To get dual channel DDR to work you need a motherboard with a chipset like nforce 2 that supports it. Then you need 2 standard DDR memory modules of the same type and size. Put those in and you get extra bandwith. If you installed 2 512mb ddr in Dual mode you should get 1024mb. I may be wrong though?
You're right. And besides nforce 2, Intel E7205 and SiS 655 also support dual channel DDR.
The simple way of explaining Dual DDR is just how the memory is accessed, instead of all the Ram being in One channel with like 3 or 4 slots (or memory banks) what they have done is basically split it in 2's (channels) of 2 slot or banks each. Now the way information is transfered and accessed is a bit differnt and faster. That is a very butchered and basic way of looking at it
Rambus Ram actually did ths first.
No, the Pentium 1 usually used Dual Channel 72-pin SIMM memory. The 386 usually used Dual Channel 30-pin SIMM memory.

well if you want to go that far back
I just meant in this present time of technology ;-)
That brings me back to my first PC..a 286 with a whopping 1 meg of ram 6Mhz that jumped to 12 when you pressed the "turbo" button.
So if I install 3x256 DDR333, then will two work wih dual channels and one work with single, or are all three are working as single rams? Installing 3 Dimm's will not make the dual channel work?? Thanks
