Yes they are definitely different as DDR stands for Double Data Ram & SDR stands for Single Data Ram and further explanation can be found here

∙ 14y agoThe difference is the speed at which is send data from the memory to the CPU. SDR = Single Data Rate DDR = Double Data Rate So in theory DDR should be twice as quick at sending data. However this doesn't mean that the computer will be twice as quick.

What is beter to speed up a p4 computer a DDR or a SDR?
If the motherboard supports both DDR and SDR RAM, it is almost always a better idea to go with DDR RAM
Can you replace pc133 with pc333?
PC133 Ram and PC333 ram are generally incompatible. PC133 RAM is SDR Ram where as PC333 is DDR RAM. Some motherboards support using either SDR or DDR but this is not usual. PC133 will not fit in the same slot as PC333.
Is ddr or sdr ram will support Intel Pentium processor 733 mhz computer?
yes
How can you recognize the sdram and ddr?
DDR and SDR have the names mentioned on the packing.You just need to read the packet.But if you don't have one then try reading on the ram chip you will find small initials on chip saying DDR with its number.
Can you DDR SDRAM in an SDR SDRAM slot?
No.
Is 512 SDR RAM or 256 DDR RAM better?
512 SDR. DDR2 is better, but more the memory better it is for your PC, irrespective of the memory technology. You have a point there but considering the current trends, i will prefer the DDR because sdram is being replaced with ddr. Especially if you planning to buy a new mother board, most MoBo's nowadays are of ddr. But speed and capability is better than having plenty of ram. It is with the speed of access not only the space. Besides, it's better to consider efficiency, right?
Ddr sdram can replace by ddr2?
No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
Which is more speedy sdr or ddr rams?
The ddr rams are much faster than sdr rams. In ddr rams the data rate is twice than that sdram. Since the data can be stored on both the ends of the ddr in contrast to the single sided data storage in sdrams, the ddr rams are considered much faster than its couterpart. Their name itself describes this difference single data rate - sd ram double data rate - dd ram. ddr2 rams are even faster than the ddr1 rams
What type of RAM would a computer with an Intel Pentium 4 1.7 GHz processor have?
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.
Can you use DDR SDRAM modules in an SDR SDRAM slot?
No.
If you have three slots on your motherboard and three 256 sdr RAM chips can you put them all in for a total of 768 sdr?
yes, you can. Make sure they're all the right speed and type of RAM though. If you're putting older sticks of SD RAM in a newer computer that uses DDR RAM, you'll either get errors or just lacking performance.
Can you convert a motherboard that uses SDR SDRAM modules to DDR SDRAM?
No.
