|DDR PC3200||400 MHz|
|DDR RAM Type||No of Notche||Number of Pins|
Synchronous RAM SDRAM – It is synchronised to the same crystal. It has 168 pins with two notches. Only RAM that has notches.
Double Data Rate RAM DDRAM
Any random click of the clock, this will give two bits of data to us. How do we define speed? Motherboard needs RAM at a certain speed. This is called DDR or PC rating.
The additional pins in DDR5 RAM are needed to support the increased data transfer rates and improved performance of the new standard. DDR5 RAM operates at higher frequencies than DDR4 RAM, with some modules supporting speeds of up to 8400 MHz. In addition, DDR5 RAM introduces new features such as on-die ECC (Error Correction Code) and DBI (Data Block Integrity) to improve reliability and reduce power consumption.
- SRAM is used for cache memory
- If a motherbaord supports dual channel memory, you can use DDR RAMS not SDRAM
- L1 cache memory is located in CPU and L2 cache memory is located in motherbaord
- Laptops use SODIM RAM modules
- ECC RAM protects against data corruption
- If memory data is corrupted, pairity error will be created
- A computer’s BIOS/UEFI code is typically stored in ROM Read only memory
