TMonitor – Real time CPU clock monitoring

One of the many interesting features of the Intel Core i7 processor is the Intel Turbo Boost technology. While most modern processors are capable of running at various clock frequencies depending on the power usage, Turbo Boost is different. Instead of throttling down clock frequencies, Turbo Boost allows the processor to run at clock speeds higher than the stock speed. Turbo Boost is an over clocking feature managed autonomously by the processor.

The amount of over clocking depends on how heavily the cores of the processor are utilized and how much power is available. If the CPU is operating below rated temperature and power and if there is enough headroom, the clock speed of one or more of the cores could be automatically increased resulting in increased performance.

TMonitor is a CPU clock monitoring tool that allows you to watch the fluctuating clock speed of each core of the processor in real time. This tool is particularly useful in visualizing the Turbo Boost feature of the Core i7 processor. A very high refresh rate (20 times per second) allows visualization of even the smallest clock variation in real time.

The following screenshot shows the effect of Turbo Boost on an Intel Core i7 870 processor.


TMonitor is designed to work only with Intel Core 2 and Core i3/i5/i7 processors at the moment.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

Diagram 101: Different Types of Diagrams and When To Use Them

Diagrams are a great way to visualize information and convey meaning. The problem is that there’s too many different types of diagrams, so it can be hard to know which ones you should use in any given situation. To help you out, we’ve created this diagram that lays out the 7 most common types of diagrams and when they’re best used:

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.
