- RAM (Random Access Memory) is a temporary, working storage space in a computer, essential for modern computing devices.
- Memory speed terminology has evolved, especially with the introduction of DDR (Double Data Rate) memory, which sends data twice per clock cycle.
- Memory speed can be described in various ways: Clock Frequency (Hz), Transfer Rate (MT/s), Bit Rate (Mbps), and JEDEC standards naming (e.g., DDR5-6400).
- Latency and timings are crucial for RAM performance, with smaller numbers indicating lower latency, though actual latency depends on memory speed.
- Overclocking memory using XMP or EXPO profiles can increase performance but may lead to instability and higher failure rates.
- Memory channels are vital for feeding data to multiple CPU cores, with more cores requiring more memory channels for greater bandwidth.
- Theoretical maximum memory bandwidth is calculated by multiplying transfer rate, bits per transmission, and the number of memory channels.
