Running and Reading CPU-Z
CPU-Z is a small application that tells you a lot about your system components and can help with troubleshooting.
We will now go through all of the relevant information that we may need.
The main screen when you start the application (which is also the CPU screen):
A lot of this you won’t need to know, but for troubleshooting the following points are useful:
Name: This tells us which processor you have in your system.
Code Name: This is the name of the specific generation of CPU you have. Sometimes a CPU will be manufactured across a couple generations and still have the same name.
Max TDP: Something you need to keep in mind when calculating your computer’s total power draw when making sure your power supply is adequate for your system.
Core Voltage: Having your voltage set too high can cause system instability.
Instructions: Useful for diagnosing specific software issues. E.g. certain emulation software requires SSE 4 or higher to function properly.
Core Speed: The effective speed of your processor. This determines how many instructions your processor can do per second.
Bus Speed: Determines how fast information can be sent between the CPU and other parts of the computer.
Multiplier: The ratio of internal cycles to external cycles in the CPU.
Multiplier X Bus Speed = Core Speed.
Mainboard (Motherboard) Screen:
This screen gives you some basic information about your motherboard.
The only information we’re likely to need from this screen is the:
-Motherboard Model: Tells you exactly which motherboard you have so you can get the proper BIOS updates etc.
-BIOS information.
Memory Screen:
This screen gives you information about your Memory (or RAM).
The only information we’re likely to need from this screen is the:
-Size: The total amount of RAM that you have in your system.
-DRAM Frequency: The speed at which you’re RAM operates.
CAS Timing are for advanced use only and you’ll almost never have to worry about it.
SPD screen:
The SPD screen gives you more information about each specific module of RAM you have installed in each RAM slot on your motherboard.
The information that we might need from this screen is the:
-Module Size: The amount of RAM on that specific module.
-Max Bandwidth: Same as DRAM Frequency
-Manufacturer: The company that made that stick of RAM.
-Part Number and Serial Number
Graphics Screen:
The screen gives you information about your graphics card:
Chances are we won’t need any information from this screen. Issues with graphics cards are usually a result of the graphics card drivers that are installed. For more information about your graphics card use the ‘dxdiag’ command (for Windows only) or use GPU-Z.
About Screen:
This screen provides information about CPU-Z.
This screen also tells you the version and build of Windows that you are running, as well as the version of DirectX you have installed.
You can also save a validation screenshot (basically a certificate of authentication for overclockers) and you can save a report, as either a text file or html file, which contains all the information gathered by CPU-Z. We may ask you for a copy of this report during troubleshooting.
