Frequently Asked Questions
Quick answers about AIDA64 editions, compatibility, licensing, and troubleshooting. For more questions and answers see ourFAQandGuides.
Which Windows versions are supported?
AIDA64 supports all current 64-bit Windows: Windows PE, Server 2003 through 2022, Vista, 7, 8, 8.1, 10, 11. See legacy compatibility documentation for older builds.
What is the difference between Extreme and Business?
Extreme is for home users and enthusiasts: system info, diagnostics, benchmarks. Business adds network inventory, remote control, SQL database, change tracking, and is licensed for corporate use.Compare all editions.
Business vs Engineer?
Engineer has full diagnostics and benchmarks; license is per engineer (unlimited PCs). Business includes everything in Engineer plus network audit, remote control, SQL, and is for company-wide use.
Business vs Network Audit?
Network Audit is a dedicated inventory solution (hardware/software audit, reporting). Business has all of that plus remote control, remote monitoring, and full diagnostics/benchmarks.
Can I run AIDA64 without installing?
Yes. Extreme and Engineer are available as ZIP packages—extract and run. Business and Network Audit are ZIP only. You can also run from USB or network share.
What report formats are supported?
Extreme and Engineer: text, HTML, MHTML. Business and Network Audit add XML, CSV, MIF (SMS), INI, and direct SQL database output.
Safe CPU/motherboard/GPU/HDD temperatures?
CPUs: best below 70°C; throttle around 80–90°C. Motherboards: below 50°C. GPUs: can reach 100–110°C with driver protection. HDDs: best below 50°C; data not guaranteed above 60°C.
What does "Aux" temperature mean?
Sensor chip layouts are not standardized. "Aux" can be CPU, motherboard, or an unconnected pin—so it may show a bogus value. If labels seem wrong, report your board and AIDA64 version in the community forum.
Which external LCDs are supported?
Over 50 LCD and VFD devices. Full list: see external display support documentation (50+ LCD and VFD devices).
AIDA64 locks up at "Scanning PCI devices"

Logon script runs 5 minutes late (Windows 8.1+)
From 8.1/2012 R2, logon scripts are delayed by 5 minutes. To run immediately: Computer Configuration → Policies → Administrative Templates → System → Group Policy → Configure Logon Script Delay → Disable.
How do I export a report to PDF?
Use Report → Report Wizard and choose HTML or MHTML. Open the report in a browser and print to PDF via the browser's Print → Save as PDF option. For automated PDF output, use a third-party converter or script that converts the HTML report to PDF.
Does AIDA64 work on ARM or Windows on ARM?
AIDA64 is built for x86/x64. Windows on ARM (e.g. Snapdragon PCs) can run x86/x64 apps via emulation, but AIDA64 relies on low-level hardware access that may not work correctly under emulation. Use the native x64 version on standard Intel/AMD PCs for full support.
What is the System Stability Test and how long should I run it?
The stability test stresses CPU, FPU, cache, memory, and optionally disk and GPU. It is used to verify overclocks and cooling. Run at least 30 minutes; many users run 1–2 hours or overnight. If errors appear, reduce overclock or improve cooling.
Can I use AIDA64 SensorPanel on a separate small display?
Yes. SensorPanel can be dragged to a second monitor or a small LCD/VFD. Many users put it on a 5–7 inch display or a secondary monitor. You can customize layout, fonts, colors, and which sensors to show.
Why does my GPU show 0°C or wrong temperature?
Some GPUs expose temperatures only under load or via a specific driver interface. Update your graphics driver. If the card is idle, certain sensors may not report until the GPU is used. Try running the GPGPU benchmark to warm the GPU and see if readings appear.
Difference between trial and purchased license?
Trial has a limited period and may show reminders. A valid license removes the trial limit and gives you updates during the maintenance period. You can switch from trial to licensed by entering your key in File → Preferences → About / License.
Can I run the benchmark in a script or from command line?
Yes. Use command-line options such as /BENCHCPU, /BENCHMEM, /BENCHDISK, etc. Runaida64.exe /?for a list. Results can be written to a file. Useful for automated testing or comparing systems.
How do I add a custom sensor or label in SensorPanel?
In SensorPanel, use the toolbar to add items: right-click or use Insert to add "Sensor", "Graph", "Gauge", "Static label", etc. Choose the sensor from the list (e.g. CPU temperature, GPU usage). You can resize, move, and style each element.
Does AIDA64 support RAID detection?
Yes. AIDA64 detects RAID controllers and arrays. Storage information is shown under Computer → Storage. For RAID health and SMART data, see the storage devices listed there; support depends on the controller and driver.
Why is "Unknown" shown for some hardware?
New or rare hardware may not be in the database yet. Update AIDA64 to the latest build. If still unknown, the manufacturer or model might not be fully identified by the detection logic; future updates often add support.
Can I monitor multiple PCs from one screen?
Yes, with Business or Engineer. Use Remote → Monitor Remote Computers or connect to each PC via Remote Report Wizard. You need AIDA64 running on each remote PC with incoming connections enabled (e.g. /ACCEPTBG in a logon script).
What is the cache/memory benchmark useful for?
It measures memory bandwidth and latency (L1/L2/L3 cache and RAM). Useful for comparing RAM kits, tuning memory overclocks, and checking that dual-channel or XMP is working. Run it before and after changing memory settings.
How do I schedule an audit to run daily?
Use Windows Task Scheduler. Create a task that runsaida64.exe /AUDIT /R C:\Reports\%COMPUTERNAME% /CSV /SAFE /SILENT(adjust path as needed). Set the trigger to daily at the desired time. Business/Network Audit can also write to SQL for central collection.
Why does AIDA64 show different CPU speed than BIOS?
AIDA64 shows the current operating frequency (which can change with power management, load, and turbo). BIOS often shows the maximum multiplier or base clock. Under load with turbo enabled, AIDA64 should report the actual boosted frequency.
Can I use AIDA64 on a virtual machine?
It runs in VMs, but hardware info will reflect the virtualized hardware (e.g. generic CPU, virtual disk). Stress tests and some sensors may not behave like on physical hardware. For real hardware monitoring and benchmarks, use a physical PC.
What is GPGPU benchmark?
It benchmarks the GPU's general-purpose compute (OpenCL, etc.), not just 3D graphics. Useful for comparing GPUs in compute workloads and checking that the OpenCL driver is working. Results depend on GPU and driver.
How do I hide the system tray icon?
Run with/SILENTor disable the tray icon in File → Preferences → General. In silent mode, AIDA64 runs in the background without tray icon or notifications; useful for scripted or headless use.
Does AIDA64 need .NET or Visual C++ runtime?
AIDA64 is a native application and does not require .NET. It may use Visual C++ runtime libraries that are usually already installed with Windows or other software. If you get a missing DLL error, install the latest Visual C++ Redistributable for your Windows architecture.
How do I compare two PCs' reports?
Generate reports (e.g. HTML or CSV) from each PC and open them side by side. For CSV, you can use Excel or a script to diff or merge. Business/Engineer with remote access let you open remote reports from one machine for quick comparison.
What is the difference between disk benchmark and SSD benchmark?
Both measure storage performance. The disk benchmark tests sequential and random read/write with configurable block sizes. The SSD-specific test may include additional metrics relevant to SSDs. Use either to compare drives or verify performance after a clone or new install.
