Effective memory clock what is

Expressing memory clock speed is a bit more complex. DDR memory can transfer data two times per clock cycle by sending two signals during one data cycle instead of one. This means that the effective RAM clock speed is two times its raw frequency. They feature two different clock speeds; the core clock and the memory clock speed. Each graphics card has both the GPU chip and the memory chips needed for video data.

And both of these have their independent clock speeds. Nvidia GPUs have the base and boost clock speeds. It would be best to be interested in the boost clock speed since this is the GPU frequency when under load. What does Memory Clock effective mean? Forums Hardware Systems. JavaScript is disabled.

Question PC not stable at stock clock speeds for memory. As we said, GPU-Z displays the real clock speed. GPU-Z shows real memory speed. I hope the memory speed you see in graphics cards reviews or in your favorite GPU tool is clear now. Usually caused by the driver getting stuck in a lower power state. When choosing a GPU you would, of course, want to compare the raw performance of each individual graphics card and graphics card model.

One thing that varies between third-party models, is the memory clock. Most people tend to look at just the core clock for a scope on what kind of FPS they should be expecting in games, but does the memory clock affect that at all?

Relatively speaking, if you were to overclock your GPU memory clock it should give a very slight performance increase in most cases, it varies from game to game. This will be the most invaluable number you find on your graphics card, because bigger means better.

Generally the faster your core clock, the higher FPS games will run at, but this only applies when comparing the same type of graphics card to a different model of itself eg.
