SIV is an extremely comprehensive system information tool that tells you everything you could ever want to know about your PC.
To take an example, when you launch the program you'll see a button called Volumes, and so you might think this would lead to a screen that lists your PCs drives, their free space and so on.
What you actually get is much, much more. Like pointers to your various drive types, manufacturers, serial numbers and controllers. There's geometry data (the number of cylinders, tracks, sectors and more). Information on partition layouts. And live file system statistics, so you can see which drives are being accessed the most.
There are specific reports on your USB and SCSI drives. Low-level Windows data like volume GUID names. Real-time SMART drive monitoring, so for instance you can see the current temperature of any SMART-compatible drives. Oh, and of course if you just want to know the capacity and free space of your various drives, then that's available too.
SIV offers the same in-depth reports on other areas of your hardware - the CPU, RAM, GPU, system buses, and a whole lot more.
The program also provides detailed network information, and troubleshooting tools.
And the Windows section is something like a supercharged Task Manager, telling you all about drivers, services and running processes, memory use, paging, loaded DLLs, security privileges and more.
The program's interface is a little odd, and there's so much available here that it can take a while to pick out the data you need. But there are few better ways to explore the technicalities of your PC, and others you might encounter, especially as SIV is portable and supports every version of Windows from 95 upwards (the server editions, too).
Version 5.26 changes include (history):
- Windows 10 RS4 Build 17046 support. Enabled operation of [ACPI HAL], [ACPI Buses], [ACPI Eval] and [ACPI Ports].
- Added highlighting support for GPU Clock Speeds + Power, CPU + GPU Core Voltages, etc.. See the [Highlight Setup] and [Colour Setup] panels.
- Added a few more colour blobs which can be user defined via the [Colour Names] (Menu->Help->Colour Names) panel, Export/Import RGB Colour Names and RGB Colour Setups which implicitly enables Hot Key switching.
- Enhanced [View Menus] to be width resizable, use the Left/Clickable Text colour for the headings which have popup sub-menus.
- Added plots + the power source to [CPU Speed Ratios] and make the panel width resizable by dragging the edge. With just SIV active systems typically run at the minimum speed over 99% of the time (CPU-0 to CPU-10), but other utilities usually cause higher speeds to be used (CPU-12 to CPU-22). Ideally any monitoring utility should not cause CPUs to keep speeding up.
- Updated [CPU Usage] + [CPU Stress] to be width resizable, run the Whetstone benchmark and improved the plots.
- Added support to force the V0.4.173 CLCP fan type from [Link Fans] by Left/Clicking on the fan type blob.
- Added Gigabyte Z370 Gaming 7 motherboard support.
