System Information Viewer is a general Windows utility for dumping lots of useful Windows, Network and hardware info - CPU info, PCI info, USB info, Machine Info, Hardware Sensors, Networked computers, Operating System Information and more

Changelog:

Added SMBus support to the SIV driver and implemented the [SMB Bus] panel which will show all the SMBus Slave Devices on the system. By default the range 0x06 to 0x5F is searched, to change this use the [Tune] panel to update the SMBus Base and SMBus Limit SIV registry entries.
Added the [SPD Details] and [SPD Summary] panels which report the SPD information for the system DIMMs. Added [ SPD ] to the initial screen as to replace [SMART] which is available via the colour blob.
Added Memory Timing reporting for the Intel 5000, 5400 and 7300 chipsets by reading the current values from the AMBs (Advanced Memory Buffers).
Added support for the AMD Phenom II X6 (Thuban) and Phenom II X4 (Zosma) Processors.
Added PCIe support for the VIA P4M900, VX800 and VN1000 chipsets.
Added the [System Metrics] page which displays the current System Metric information.
Added the [MSR Core] page which displays the per core MSR derived sensor information. Added support for motherboards with multiple LPC I/O Sensors such as the EVGA W555. Use Nuvoton after the Winbond spin off.
Enhanced USB 3.0 support to report Super as a device speed and decode Endpoint Companion descriptors.
Resolved the issue of SIV, by default, only using 20 lines on some systems and added -NOSAME to disable same-as-before suppression.


System
Monitoring
On some systems, notably Windows 7 with nVidia chipsets, the [SMART] panel may fail to report information. In many cases this issue can be resolved to using the -SCSI command line option. When this option is selected all requests to read the drive SMART information are routed via the SIV Kernel Driver which actions them using IRP_MJ_SCSI requests (hence -SCSI). Note that -SCSI is sticky, so you only need to specify it once and need to use -NOSCSI to stop the IRP_MJ_SCSI mode of operation.
On some Dell systems when no Temperatures, Fan Speeds or Voltages are displayed specifing the -DELL command line option may resolve this. When this option is selected SIV will attempt to read this information from the Dell BIOS. I use this option on my Dell 490 Workstation and Dell 1720 Laptop. Note that -DELL is sticky, so you only need to specify it once and need to use -NODELL to stop the Dell BIOS mode of operation.

SMBus
Scans
The default SMBus slave scan range of 0x06 to 0x60 was selected as some systems have issues when accesses to SMBus slave addresses above 0x5F are made. If you decide to extend the scan range then your SMBus may lock up and you will need to re-boot to get it working again!
When SIV, on the [SMB Bus] page, does not have a device description and you know what that chip is please e-mail the details so I can add it. If you have the datasheet for the chip please attach it.
Currently SIV supports almost all Intel and most VIA SMBus controllers. I plan to add support for AMD/ATI and nVidia, but as I do not have access to any PCs with those chipsets I have not as yet done this. If you have a system with an unsupported chipset and would like to help me add support please contact me.
