1. AMD/ATI ULPS: System hang or crash on Crossfire systems
Description: On systems with AMD/ATI multi-GPUs, there might be problems because of the Catalyst ULPS feature. This feature disables the secondary GPU when not utilized so, that any direct access to this GPU can cause a system hang, blue screen or reset. See this thread for more information: http://www.hwinfo.com/forum/Thread-Possi...alyst-10-2
Workaround: Disable ULPS feature via registry or using Sapphire TriXX tool.
2. nVidia Optimus: Discrete (Secondary) GPU not found
Description: On systems with hybrid graphics - primary integrated GPU (i.e. Intel HD Graphics) and secondary discrete nVidia GPU (DGPU) with nVidia Optimus technology enabled, HWiNFO32/64 might not be able to detect the nVidia GPU when launched and DGPU was disabled by Optimus. The nVidia Optimus technology completely disables the DGPU when not utilized, so that it's not even visible on PCI bus.
Workaround: HWiNFO 32/64 v4.16 and later implement a method which wakes up the disabled DGPU during launch, then the DGPU goes back into off state, so HWiNFO will not report its parameters until another application wakes up the GPU. This behavior is intentional to save power and not influence the GPU's desired state.
3. Higher system load or latency during sensor monitoring.
Description: When performing sensor monitoring, on some systems (depending on sensors present), the user might experience higher system load or latency (including DPC). This can be caused by certain sensors, especially sensors of the "EC" type, "DELL SMI", or disk SMART sensors (depending on controller and disk driver used).
Workaround: Disable monitoring of particular sensor items (right-click and "Disable monitoring") until the latency/load is reduced.
4. Autostart under Windows Vista and later.
Description: When configuring HWiNFO for "Auto Start" under Windows Vista and later systems with UAC enabled, the automatic start might not work properly or require the UAC prompt each time.
Workaround: Use the Windows Task Scheduler to configure auto start of HWiNFO.
5. Missing disk, SMART and drive temperature information on Intel RST 11.5 drivers.
Description: Using Intel Rapid Storage Technology (RST) driver v11.5 or Enterprise RST driver will probably cause loss of disk information including SMART and temperature. This is a bug in the Intel RST driver v11.5 and Intel fixed this problem in version 188.8.131.523 of the RST driver and Enterprise RST driver v3.2.
Workaround: Update the RST driver to v184.108.40.2063 (or eRST to v3.2) at least.
6. Problems with CPU recognition
Description: If you experience problems with CPU recognition (parameters, number of cores, etc) and you have a setting in BIOS called "Limit CPUID Maximum Function" set to "Enabled", please set this to "Disabled".
Solution: It is strongly recommended for all users that "Limit CPUID Maximum Function" setting in BIOS is set to "Disabled".
