Yes, but only with other DDR, not SDR. DDR is 184 pins where SDRAM is 164 pins. There are a few factors that will affect the speed of you memory: 1) The memory itself If you buy cheap memory then you might have slow memory. the chip can only move as fast as its slowest memory section 2) Maximum clock speed on the motherboard Your memory will only run as fast as your mobo can run it. If your mobo supports up to PC2700, buying PC3200 will only run at PC2700 speeds

In SDRAM, rising and falling edges are the opposite edges of a memory module through which data can be transferred. SDRAMs that are designed this way are called DDR (double data rate) SDRAMs.

No. SDR SDRAM and DDR SDRAM modules are not interchangeable.

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

A DDR DIMM has 184 pins, while a DDR2 DIMM has 240 pins. They will physically only fit in slots designed specifically for them and are not interchangeable.

No, not all are interchangeable. be careful of brand and model.

The symbol for DDR Corp. in the NYSE is: DDR.

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.

User Avatar

there is no difference between ddr and ddr1 . both are the same

User Avatar

ddr dimm is not compatible with the ddr 2 because of the notches. the different notch positions will keep you form installing it.

DDR Motorsport's population is 10.

Yes they are. Almost all of the sport frames have interchangeable lenses.

The advantages as each proceed to the next DDR version. Not only is it more capable, but it is faster. However, an issue is that the latency's are really high as you go to DDR3, while they are lower in DDR1 and DDR2. I am not sure for the reason of this, however I will define latency. Latency is the time it takes the RAM to 'communicate.' The higher the latency, the worse. However, somehow, DDR3 uses high latency and yet it is faster than DDR2 and DDR1. Pro-tip: DDR versions are not interchangeable. For example, I can't put a DDR2 RAM stick in a DDR3 memory module. The notches are orientated differently to prevent this. Check your DDR version before buying RAM, and buy the right kind!

PC-2700 is DDR RAM at 333 MHz. PC2-3200 is DDR2 RAM running at 400 MHz. They are not interchangeable.

DDR Corp. was created in 1965.

No you have to change the whole system build to change from DDR to SD or SD to DDR.

User Avatar

No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.

User Avatar

There is two types. There is DDR notebook RAM and there is DDR desktop ram. They can't be used vin each other (notebook RAM can't be used in a desktop) unless (in rare circumstances) you happen to have a notebook ram port on your desktop's motherboard. But no, DDR is a technology. Both desktops and notebooks support this technology because there is notebook DDR and desktop DDR. but notebook DDR can't be put in desktop DDR and vice versa.

All speakers can be interchangeable between desktops and laptops, as they all use mini connectors.

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.
