Stability

 

This page lists several options to control the low-level hardware detection modules of AIDA64.  When experiencing instability issues, these options can be used to make AIDA64 work properly.  Please scroll down to read explanation of each options.

 

preferences_stability

 

Load kernel driver

 

This option controls the using of AIDA64 kernel driver.  In most cases instability issues can be avoided by preventing the use of AIDA64 kernel driver.

 

Low-level MSR operations

 

This option controls the using of MSR instructions (RDMSR and WRMSR).  When this option is disabled, the detection of CPU FSB and CPU multiplier cannot be used.

 

Low-level PCI bus operations

 

This option controls the using of low-level PCI bus scanning that may cause system lockup in old systems, typically equipped with S3 PCI or Trident PCI video cards.  When this option is disabled, neither of motherboard chipset information, motherboard buses information, GPU information, SPD information and sensor information can be provided.

 

Low-level SMBus operations

 

This option controls the using of low-level SMBus scanning that may cause system lockup in rare cases.  When this option is disabled, neither of SPD information and sensor information can be provided.

 

Low-level sensor operations

 

This option controls the using of low-level sensor scanning that may cause system lockup, CPU fan stop or system audible warnings in rare cases.  When this option is disabled, no sensor information can be provided.

 

Fan divisor reconfiguration

 

This option controls the using of the fan divisor reconfiguration feature of the hardware monitoring module of AIDA64.  Fan divisor reconfiguration ensures that status of all fans -- including low-RPM fans -- can be detected properly.  However, MSI Core Cell and PC Alert applications collide with applications that reconfigure fan divisors, so AIDA64 and those applications can be used simultaneously only by having this option disabled.

 

Low-level SMART operations

 

This option controls the using of low-level SMART disk calls that may cause system lockup in rare cases.  When this option is disabled, no disk temperature or SMART disk health status information can be provided.

 

RAID member enumeration

 

This option controls the using of low-level RAID member enumeration calls for RAID arrays that may cause system lockup in rare cases.  When this option is disabled, no ATA autodetect information or SMART disk health status information can be provided for RAID arrays.

 

RAID SMART support

 

This option controls the using of low-level SMART disk calls for RAID arrays that may cause system lockup in rare cases.  When this option is disabled, no disk temperature or SMART disk health status information can be provided for RAID arrays.

 

Adaptec RAID support

 

This option controls the using of low-level Adaptec RAID calls that may cause slow startup in rare cases.  When this option is disabled, no disk temperature or SMART disk health status information can be provided for Adaptec RAID arrays.

 

nVIDIA GPU SMBus access through nVIDIA ForceWare

 

This option can be used to improve the stability of GPU sensor readout on Asus cards with Asus SmartDoctor installed and running.

 

Change to 3D profile on nVIDIA video adapters

 

This option controls the switching to 3D profile in the nVIDIA GPU detection module of AIDA64.  This option should be enabled to measure the maximum clock of the GPU.  However, when the video adapter switches to 3D profile, the fan speed may also increase.

 

SMBus access through ACPI

 

This option can be used on Asus motherboards to avoid collisions between AIDA64 hardware monitoring module and Asus' own hardware monitoring and overclocking applications (e.g. Asus AI Booster, Asus AI Suite, Asus PC Probe II, Asus SixEngine, etc).  This option should not be used on non-Asus motherboards.

 

Apple SMC sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures and cooling fan speeds via Apple SMC sensors.  In rare cases polling the Apple SMC sensor device may cause system instability.

 

Asetek LC sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures, cooling fan speeds and pump speeds via Asetek LC based AIO water coolers. Such devices include Antec CC, Corsair H80iGT, Corsair H80i v2, Corsair H100iGTX, Corsair H100i v2, Corsair H110iGTX, Corsair H115i, NZXT Kraken X31, NZXT Kraken X41, NZXT Kraken X61, etc.

 

Asus ATKEX sensor support (Asus ROG)

 

This option controls the using of low-level AIDA64 features to measure temperatures and cooling fan speeds via Asus ATKEX driver calls on Asus ROG motherboards.  This option can only be used when Asus AI Suite is installed.

 

Corsair Link sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures and cooling fan speeds via Corsair Link.  In rare cases polling Corsair Link may cause system slowdown or lockup.

 

Dell SMI sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures and cooling fan speeds via Dell SMI sensors.  In rare cases polling the Dell SMI sensor device may cause system slowdown or lockup.

 

GRID+ V2 sensor support

 

This option controls the using of low-level AIDA64 features to measure cooling fan speeds via the NZXT GRID+ V2 sensor device. AIDA64 may collide with NZXT CAM software when this option is enabled.

 

Heatmaster II sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures, cooling fan speeds and pump speeds via the AlphaCool Heatmaster II sensor device.

 

HID UPS sensor support

 

This option controls the using of low-level AIDA64 features to measure battery power and voltages via HID UPS sensors.  In rare cases polling HID UPS sensors may cause system slowdown.

 

Koolance TMS-200 sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures and cooling fan speeds via Koolance TMS-200 family sensor devices.  To avoid potential incompatibility issues this option is disabled by default, and shall only be enabled when a Koolance TMS-200 device is connected to the system.

 

T-Balancer sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures via T-Balancer sensor devices.

 

DIMM thermal sensor support

 

This option controls the using of low-level AIDA64 features to measure temperatures of DIMM memory modules using SMBus operations.  To avoid potential incompatibility issues this option is disabled by default, and shall only be enabled when a thermal sensor capable memory module is installed.

 

Toshiba TVALZ sensor support

 

This option controls the using of low-level AIDA64 features to measure cooling fan speeds via Toshiba TVALZ sensors.  In rare cases polling the Toshiba TVALZ sensor device may cause system instability.

 

Volterra VT11xx sensor support

 

This option controls the using of low-level AIDA64 features to measure temperature, voltage and power draw via Volterra VT11xx GPU sensor chips.  In rare cases polling a Volterra VT11xx sensor chip may cause system instability while running 3D games.

 

GPU sensor support

 

This option controls the using of low-level AIDA64 features to measure temperature, voltage and cooling fan speeds for AMD and nVIDIA video adapters.  In rare cases polling GPU sensor chips may cause system slowdown or lockup.

 

GPU fan speed measurement

 

This option controls the using of low-level AIDA64 features to measure cooling fan speeds for AMD and nVIDIA video adapters.  In rare cases polling GPU fans may cause system instability or automatic fan speed control issues.

 

Multi-GPU support

 

This option controls the using of the multi-GPU features of AIDA64.  On AMD CrossFireX configurations (including multi-GPU AMD video cards, e.g. Radeon HD 5970) the ULPS power-saving feature of the AMD Catalyst video driver may cause various issues while running AIDA64.  In such cases multi-GPU support has to be disabled to restore system stability.
