6. Is it possible to launch AIDA64 from a CD-ROM disc, DVD-ROM disc, Blu-ray disc, or flash drive?

It is fully supported. AIDA64 files can be simply extracted from the ZIP package and burnt to a CD/DVD/BD disc, or copied to a DVD-RAM disc or flash drive.

7. Why is the information provided by the
Computer / DMI page inaccurate?

The reliability and accuracy of DMI information depends on the manufacturer of the motherboard or the computer (when a brand computer). When vendors do not take the time to fill in the DMI tables properly, all applications reading DMI will indicate the same wrong information. This is not the fault of AIDA64.

8. Is it possible to use AIDA64 on 64-bit Windows systems based on 64-bit AMD Opteron, AMD Phenom, Intel Core 2, Intel Core i3/i5/i7, Intel Xeon processors?

AIDA64 implements full support for 64-bit systems, including 64-bit version of all its benchmark methods. Benchmarks are backwards compatible with legacy 32-bit processors.

9. Does AIDA64 support Windows Vista, Windows Server 2008, Windows 7 or Windows PE?

AIDA64 has full support for all current 32-bit and 64-bit PC Windows systems including Windows 95, Windows 98, Windows Me, Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, Windows XP 64-Bit Edition, Windows XP x64 Edition, Windows Vista, Windows Server 2008, Windows 7 and Windows PE.

10. Is there an AIDA64 version running under DOS, Mac OS, Mac OS X, Linux or UNIX?

AIDA64 supports Microsoft Windows systems only.

11. Is it possible to find out the product key of Office 97 or Office 2000?

AIDA64 license module is capable of detecting product key of Office XP, Office 2003 and Office 2007 only.

How to determine the firmware version of optical drives and hard disk drives?

Firmware version of optical drives and SCSI hard disk drives is displayed on the Storage / ASPI page. Firmware version of ATA and SATA hard disk drives is displayed on the Storage / ATA page.

13. What does the “Aux” temperature shown on the
Computer / Sensor page mean?

There is no standard for sensor registers layout, so the “Aux” temperature could show the temperature of the CPU or the motherboard, or might be a non-connected wire of the sensor chip, and so it could show a bogus value.

14. What does the “CPU Diode” temperature shown on the
Computer / Sensor page mean?

“CPU” temperature means the temperature measured around the CPU socket, whereas “CPU Diode” temperature means the temperature of the CPU core.

15. The web links on the
Computer / Summary and other pages do not work, clicking on them does not open my web browser. What’s the problem here?

It means Windows default web browser is not selected.

16. The temperature, voltage or fan rotation values on the
Computer / Sensor page are inaccurate. For example, a bogus “Aux” temperature is displayed with a nonsense value; or the CPU and motherboard temperatures are reversed; or the -5V or -12V lines display a completely off positive value. How to make the sensor values more accurate?

Unfortunately there is no standard for sensor chip registers layout, hence in several cases the registers layout that AIDA64 uses could fail to be accurate. In such cases please contact us through the AIDA64 Discussion Forum, under the “Hardware Monitoring” forum. When you open the new topic, please make sure to indicate the version number of AIDA64 you’re using, the model of your motherboard; and also copy-paste the full content of the Computer / Sensor page into the new topic you open.

17. When starting AIDA64 it locks up the computer while it displays “Scanning PCI devices”. How can this be avoided?

Create a new text file (e.g. using Notepad) in AIDA64 folder, name it: “AIDA64.INI”. Write the following 2 lines into the new file:



18. Other software (e.g. CoreTemp, HWMonitor) show different core temperatures than AIDA64. Is it possible to adjust the core temperatures on an Intel CPU to match what other software measure?

Modern Intel processors use DTS on-die temperature sensing diode to provide core temperature measurement. AIDA64 fully complies to the latest Intel DTS Specifications, and uses the TJMax values published by Intel. With DTS the measured core diode temperatures are relative to a TJMax temperature value, which is specific to a particular CPU model & stepping. By adjusting TJMax, it is possible to adjust the measured core temperatures in both directions. The TJMax value AIDA64 uses can be changed in main menu / File / Preferences / Hardware Monitoring.

19. What is the maximum operational temperature for a CPU, motherboard, video adapter, or hard disk drive?

Most modern processors work best while running below 70 Celsius, but will not fail or break below 80-90 Celsius. Modern Intel processors use a special hardware logic to prevent overheating: they throttle themselves down to prevent physical damage, and they shut the computer down automatically when even via throttling the CPU keeps getting too hot. Most motherboards can work stable while running below 50 Celsius, and physical damage will usually not occur until 60 Celsius. Modern video card GPUs can work up to 100-110 Celsius, and supplied with a video driver that implements overheating protection. Most hard disk drives work best below 50 Celsius, and they are rated to work stable below 60 Celsius. With hard disks data integrity is not guaranteed anywhere beyond 60 Celsius.

20. Is it possible to display SMART information for an external hard disk drive (e.g. WD MyBook), or for a hard disk drive placed in an external disk enclosure?

Not all USB, eSATA, or FireWire disk enclosures support SMART readout. But out of the ones that do implement that feature, AIDA64 supports most of them. In the case you can find one that is supported by other monitoring software (e.g. HD Sentinel), but unsupported by AIDA64, please contact us through the AIDA64 Discussion Forum, under the “Hardware Monitoring” forum.

21. Is it possible to display SMART information for RAID arrays?

SMART information for RAID array member drives can be displayed for 3ware, Areca, HighPoint RocketRAID 26xx, and LSI MegaIDE RAID controllers. Other RAID controllers either do not have a driver that makes SMART readout possible, or they are not supported by AIDA64.

22. My virus scanner has found a malicious file that belongs to AIDA64. Is it possible the AIDA64 distribution package is infected by a virus, trojan, or adware?

We scan all AIDA64 files we upload to our web site for viruses and other malware. Our files are 100% free of any malware or adware. In the case a security solution fires an alarm about AIDA64, then it is advised to remove AIDA64 from the computer, and download the latest version from our web site (
). It is also important to update the security software to its latest version, since there have already been numerous occasions when anti-virus products fired false alarms about AIDA64 files in the past.

23. What is MCP temperature? Is it normal that it is over 80 Celsius?

MCP is part of nVIDIA chipsets, and stands for Media and Communications Processor. It is a computer component that is designed to operate at very high temperatures. 80-90 Celsius is normal temperature for MCPs.
