333 MHz
The DDR 333 model can be purchased through Amazon. DDR 333 is a type of memory used for computers. DDR is an acronym for 'double data rate'. The number specifies the memory speed.

No. DDR RAM cannot be used to replace or upgrade a PC133 module.
Yes, absolutely because DDR rated for higher frequencies are also backward compatible. Just pay attention to the DDR generation because you DDR-I is not compatible with DDR-II.
No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
While I'm sure a destructive lunatic could force a DDR module into an older slot, they are not designed to be physically compatible. DDR modules have only a single notch, while SDR modules and slots are keyed with two notches and ridges.
no you can not use 400 MHZ ram because (PC2100 @ 266 MHZ ddr) and (PC2700 @ 333 MHZ ddr) are the only chips that are inter changable. PC3200 is 400 MHZ but it has 2 slots not just the one. It does not fit into the same type slot as either PC2700 or PC2100. I was looking at the possibility of a PC2700 ram rated at 400 MHZ but I do not think there is such a thing.
It can store 4 bits of data in each prefetch buffer. It also means that it is a ddr2 memory module
A DDR SDRAM module
If you are referring to standard RAM modules for a computer I believe you're looking for "PC1600" DDR ram. Not DDR2 or 3, just plain DDR ram. Hope this helps!
