Hundreds of motherboards are compatible with DDR SDRAM. It would be impossible to provide a comprehensive list.
No. SDRAM and DDR SDRAM are not compatible with each other.
Occasionally on older motherboards, there are slots for SDRAM and DDR RAM but, they CANNOT be used at the same time, due to the different speeds they run at.
PC133 is an SDRAM standard. SDRAM is a type of RAM.
Motherboards of that era would have had a either a combination of the older SDR SDRAM (PC100 or PC133 RAM) and DDR SDRAM, or just DDR SDRAM.For best performance, you would want to use the DDR slots.
The term DDR SDRAM refers to the phrase "double data rate synchronous dynamic random access memory". DDR SDRAM is simply a faster version of SDRAM in which data travels at a double rate. If your computer specs say that it uses DDR SDRAM it can take DDR SDRAM, but not SDRAM. DDR is 184 pins and has a notch in the bottom near the center and you will be unable to put DDR in an SDRAM mother board and also unable to put SDRAM in a DDR motherboard. Recently a new type of RAM has been introduced to market called DDR2. DDR2 is its own type and will not fit into a DDR motherboard. Hope this helps. Peace.
DDR SDRAM uses 184 pins.
No.
In order to upgrade SDRAM with DDR, you will need to replace your motherboard. DDR uses a different slot than SDRAM, so if your motherboard is using SDRAM currently, you will most likely have to replace your motherboard in order to make your system support DDR.
Yes it seems that the older p4 mother boards came with the SDRAM slot. But the newer ones don't seem to come with the SDRAM slot, they have ddr slots now.
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.
Data path widths for DDR SDRAM can be at least 8, 16, 32, 64 and 72 bits, according to a DDR SDRAM contoller chip manufacturer.
