DDR vs DDR2

Gigabyte, Intel and a few other OEM's build motherboards based on the 915 series chipset from Intel

which supports both DDR and DDR2 (so it can be used in value AND mid-range applications)

DDR vs DDR2

DDR2 is capable of higher speeds iirc, and the sticks are physically different

just like DDR-III is capable of higher speeds @ lower temps (also called GDDR3, GDDR and DDR are slightly different, but they are the same technology (GRDRAM and RDRAM are both RDRAM based, G just implies gfx use))


DDR2 is the ideal option if you are using a current generation Pentium IV on the 915, 925, 945, or 955 chipset (the 945 and 955 are going to be released soon along with the Pentium 4 EE 840 (Which is dual core))

DDR is the ideal option if you are using an older Pentium IV for Socket 478 on the 845, 865, 875, or any number of VIA or SiS chipsets

DDR is also the only option for AMD CPU's currently (well, some older (i mean like 2000-2002 or older) motherboards use SDRAM for the Athlon or Duron CPUs)

that makes sense... that along with the site linked to in the other post were what i was looking for... cool... thanks much.

You won't find a lot of boards that support both, and if you get one, it won't support both simultaneously.
