  • XMP Profiles: Most 4800 MHz RAM modules use Intel’s Extreme Memory Profile (XMP) or AMD’s equivalent (DOCP) for simplified overclocking. Enabling XMP in BIOS is typically necessary to reach advertised speeds.
  • Latency and Timings: Higher frequency RAM often comes with looser timings (higher latency numbers), which can partially offset the speed gains. Balancing frequency and latency is crucial for optimal performance.

Comparison of RAM Speeds and Latencies

Understanding the relationship between frequency and latency is essential to evaluate the real-world performance of 4800 MHz RAM. The table below compares typical DDR4/DDR5 RAM speeds, their CAS latency (CL), and the resulting true latency in nanoseconds (ns).

RAM Frequency (MHz) CAS Latency (CL) True Latency (ns) = (CL / Frequency) × 2000 Notes
3200 16 10.0 ns Common DDR4 speed with good latency
3600 18 10.0 ns Popular high-performance DDR4 setting
4800 40 16.7 ns Typical DDR5 speed with higher latency
5200 38 14.6 ns High-end DDR5 with improved timings

This comparison reveals that while 4800 MHz RAM offers a higher bandwidth, its latency is generally higher than lower frequency DDR4 RAM modules. Thus, the benefits of 4800 MHz RAM are more pronounced in bandwidth-sensitive applications rather than latency-sensitive ones.
