CPU-Z is one of the tools for overclocker. CPU-Z displays CPU, mainboard, memory, system information. CPU-Z can detect information as below…
CPU
- Name and number.
- Core stepping and process.
- Package.
- Core voltage.
- Internal and external clocks, clock multiplier.
- Supported instructions sets.
- Cache information.
Mainboard
- Vendor, model and revision.
- BIOS model and date.
- Chipset (northbridge and southbridge) and sensor.
- Graphic interface.
Memory
- Frequency and timings.
- Module(s) specification using SPD (Serial Presence Detect) : vendor, serial number, timings table.
System
- Windows and DirectX version.
Take Intel Core2 Extreme quad-core processor QX9650 for example. You can see that the CPU is running at 2400 MHz with 400 MHz bus speed. This is the power saving feature of Intel Core2 Extreme quad-core processor QX9650 where it will lower CPU multiplier to x6 on low CPU usage. This will help to cool down the CPU. And it will go up to max CPU multiplier that you set when loaded with heavy CPU usage application.
Memory information provided by CPU-Z is also useful. You can find out the memory speed and timing. I will come back on memory more after manage to tweak the memory to the next level of speed.
