والله احترنا بالاعدادات الموجودة في المنتدى للودر مرة بيكون مكان DRAM type - SD RAM او
DRAM type - DD RAM
طيب حدا يفيدنا ويفهمنا شو الفرق او شو الضرر اللي ممكن يصير في تغيير الوضعية وهل له ضرر على الفلاشة
وجزاكم الله كل خير

اذا أردت شرحآ كاملآ أخي الكريم تفضل هذا هو الفرق بين SDRAM و DDRAM

DDR standards for "Double Data Rate". DDR can transfer data on both the rising and falling edge of the clock signal, whereas standard SD ram can onle transfer data on one or the other. This means data throughput on DDR memory is twice as fast, hence the name "Double Data Rate".
Also, they are physically different: A DDR modules has one notch on the contact strip, SD modules have two




Let's start with DRAM. Dynamic Random questionAccess Memory is used to temporarily store information on computers. DRAM is made up of many cells and each cell is referred to as a bit. A cell contains a capacitor and a transistor. Since computer machine language is made up of 1s and 0s, it has the value of one when active and zero when inactive.
SDRAM or Synchronous Random Access Memory is the result of DRAM evolution. This type of memory synchronizes the input and output signals with the system board. Its speed ratings are in MHz. SDRAM was introduced in 1996 and is still used today. SDRAM transmits every clock count at a specific time.
DDR RAM (or Double Data Rate Random Access Memory) does the same but it does so twice every clock count. This makes DDR RAM twice as fast as SDRAM. Over the years, RAM has become very fast and efficient -- and it will be exciting to see what's coming next.
