Because they are the most modern and up to date technology.
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
I recently purchased a RAM randomly and I told my friend about the purchase and he asked me a question is it DDR 3 or DDR 4 or DDR 5? I told him it's not DDR RAM. lol Does anyone know what is the difference between the three and which is the best for an average user or video editor in Camtasia?
DDR by a long shot
No, they're not cross compatible. 184pin DDR is desktop memory, 200 pin ddr is a SO-DIMM, which is laptop memory.
This depends on the motherboard / chipset, not the processor. Most Pentium 4s of that speed / era would probably only support DDR RAM.
DDR-2 is the most common and least expensive route, newer CPUs and Motherboards are beginning to use DDR-3, however it is more expensive and the benefits are negligible.A minimum of 4 Gb of ram is recommended for any modern computer. Windows Vista suffers with anything less and Windows 7 RC1 rocks the socks with 4Gb of DDR-2 800 memory.
DDR Corp. (DDR)had its IPO in 1993.
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.
As of July 2014, the market cap for DDR Corp. (DDR) is $6,442,785,788.34.
depending on the laptop, it could be DDR, DDR2 or DDR3. But the form factor is all the same. Its all SO-DIMM memory
The symbol for DDR Corp. in the NYSE is: DDR.
DDR SDRAM for laptops come ineither 200-pin SO-DIMMs or 172-pin micro-DIMMs
