Intermediate Users: Advanced Memory Profiles This additional qualification and effort often results in a higher price, which is why low-latency, high-speed RAM tends to be more expensive.īoth are important, but in general, higher frequencies often outweigh timings when it comes to performance impact for the average user. Memory module manufacturers know this and carefully select memory chips for each stick, testing, and pairing memory modules that can reach the highest possible performance.

Increased latency will reduce the performance and potentially eliminate the gains from a higher frequency, depending on the size of the frequency increase. This increases the time (latency) between operations, and helps to keep the transfer stable. To counter-balance stability challenges at high speeds, memory timings are often increased. Simply put, when a memory module operates at a high frequency, it is more difficult to keep it stable.

The two have to be considered together to determine the overall performance of RAM.Ĭompromises usually need to be made in order to raise one or lower the other. In an ideal world, RAM would have high frequencies and low timings.
