The disk cache in OS X can sometimes use a fair amount of the system's RAM, and clearing it can help you figure out how much RAM your applications and system processes are using. Topher, an avid Mac ...

Is increasing VRAM finally worth it? I ran the numbers on my Windows 11 PC ...

Many readers will be familiar with the idea of a glitching attack, introducing electrical noise into a computer circuit in the hope of disrupting program flow and causing unexpected behaviour which ...

Editor's Note: Demand for increasing functionality and performance in systems designs continues to drive the need for more memory even as hardware engineers balance the dynamics of system capability, ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

I have 10 Gb of ram.. is there a point where virtual memory becomes a performance decrease or becomes useless? Virtual memory is a hardware feature, and is required by most (all?) modern OSes. You're ...

One of the greatest challenges facing the designers of many-core processors is resource contention. The chart below visually lays out the problem of resource contention, but for most of us the idea is ...

Editor’s Note: Demand for increasing functionality and performance in systems designs continues to drive the need for more memory even as hardware engineers balance the dynamics of system capability, ...

Simulating more random access memory (RAM) than actually exists. Virtual memory allows the CPU to execute larger programs than it would normally be capable of, and it enables multiple programs to be ...
