Changes
Version 5.00 released on 14-May-2015
Migrated from the SHA-1 to SHA-2 code signing. This has no real impact on most systems, but to use SIV V5 on W7 you need KB3033929 installed and on Vista x64 to disable Driver Signature Verification.
Added support for Windows 10 V10.00 Build 10074. Enabled operation of [ACPI HAL], [ACPI Buses], [ACPI Eval] and [ACPI Ports].
Resolved race condition when -CRLCTL is being used that causes intermittent issues on some systems.
Added Synthetic Temperatures (Menu->Tools->Configuration->Synthetic Setup) so custom curves can use the highest reading of multiple sensors and/or this can be displayed on the [Status] panel.
Added initial Intel Core i7 (Broadwell-H) and Intel Atom (Braswell) reporting.
Added ASRock Z97 OC Formula, ASUS MAXIMUS VII GENE, P8B75, P8Z77-V, Gigabyte Z97X-UD3, MSI MS-7881, Supermicro H8DMU and X10DAX motherboard support.
Extended ASUS Rampage IV motherboard support for embedded controller temperature, fan speed and voltage reporting.
Added Nuvoton W83793G SMBus hardware monitoring support.
Added the -SINGLE command line qualifier to specify that only a single instance of SIV should be active.

Known Issues
None
Corsair
Link
Corsair Link hardware reporting is available only when the Corsair Link program is not active as CorsairLink.exe does not use the Global\Access_CorsairLink mutex to interlock access to the Corsair Link hardware. Corsair Link should have always have used a global mutex to interlock Corsair Link hardware access and if Corsair get enough requests maybe they will add it and this restriction can be removed from SIV.
If [Link Devices] does not list any Corsair devices then check that they are Supported by SIV, listed on the [USB Bus] panel, have no I/O errors and that they are reported by Device Manager in the HID (Human Interface Device) section. Does a device come and go on unplug and re-plug the USB cable or SATA power connector?
If you wish to use SIV to fully control your CL hardware then you need to specify the -CRLCTL command line qualifier typically using a shortcut. When -CRLCTL is specified SIV will if needed automatically do the EnhancedPowerManagementEnabled registry change and restart the USB device. If you have any issues and need help then you need to provide screen images of the SIV Initial Screen, [USB Bus], [Link Devices], [Link Status] and [Link Fans] panels. Even if you are not using SIV to control your CL hardware you should post these screen shots on the Corsair forum if you have CL issues and need help resolving them as they enable the root cause of many issues to be understood and resolved.
SIV stores the configured Corsair hardware settings such as custom cooling curves in the Windows registry and you can use Menu->Machine->SIV Setup->SIV Setup 4 to view this. This configuration is setup in the hardware when you start SIV and specify -CRLCTL. For the [Link Fans] and [Link Lights] pressing [Reset] will update the panel with this saved information and [Apply] will load the panel settings into the hardware. Should you wish to set all the fans to maximum speed select PWM, set 255 and then press [Apply]. To restore the saved setup press [Reset] then [Apply]. If either PWM or RPM as selected pressing [Save] is inappropriate, so it is greyed.
The Corsair Link reporting and control is only about 2% of SIV and finding the CL panels can be tricky for new users. They are all accessed by the Tools sub-menu (Menu->Tools->Link ...) or via the [Status|V] split button drop down menu. All the Corsair Link panels have buttons to directly access others. When SIV does not find any CL hardware only the [Link Devices] panel will be available.
System
Monitoring
On some systems, notably Windows 7 with nVidia chipsets and several RAID controllers, the [SMART] panel may fail to report information. In many cases this issue can be resolved by 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 specifying 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.
In addition to the command line options the SIV Configuration panel (Menu->Tools->Configure->SIV Configuration) which can be used to set the -SCSI and -DELL modes of operation.
SMBus
Locking
If programs are accessing the SMBus and either not using the locks at all or create them in the Local\ rather than the Global\ namespace the SMBus access will not work correctly. SIV detects when the Local\ namespace is being used and will switch to using it which will work when there is a single session. If there are multiple sessions then Global\ needs to be used. The [SMBus Locks] page displays the namespace the locks are currently within; this example screen shows SpeedFan 4.41 incorrectly using Local\ and SIV having switched to also using Local\. SpeedFan 4.42 has been corrected to use to use Global\ as should all other programs. Some SMBus drivers interlock SMBus operations using the INUSE_STS semaphore. SIV also implements this regime as addition to using the Access_SMBUS.HTP.Method mutex. If you have any additions, corrections or need guidance in implementing locking then e-mail me.
SMBus
Scans
By default all SMBus slave addresses are scanned (0x10 <= slave < 0x80). If SIV detects as issue with accessing a slave device it will automatically add the address to the exclusion list along with the previous device which is often the cause of the issue. It is quite common for an access to slave 0x69 to lock the system, so this is by default excluded. If there is an SMBus lock up you may need to re-boot to get the SMBus working again. You can also use the [SMBus Setup] page to manually update slave address exclusions and/or update the SMBus Scan Range.
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, most Ali, ATI, nVidia, SiS, and VIA SMBus controllers. If you have a system with an unsupported chipset, would like me to add support and are happy to test a SIV Beta then e-mail me the SIV save files (Menu->File->Save Local) from your system.
ACPI
Eval
If there is an issue with ACPI method evaluation (Menu->System->ACPI Eval) then the command siv -dbghal -save=[initial][acpi-hal][acpi-eval]=acpi.txt > acpi.log | more should be used to find and then report the ACPI method causing the issue. The last line of acpi.log will indicate the ACPI method that caused the issue. When UAC is enabled STDOUT is not available so acpi.log may be empty and the information will be in SIV_DBGOUT.log.
Issue
Reporting
If you find an issue with SIV and wish to get it resolved then please e-mail the details along with the SIV save files. In the event of an application failure please keep a copy of the memory dump file in case this is needed. The memory dump is generated by either Windows Error Reporting (WER) on Windows 7/Vista/Server 2008 or by Dr Watson on earlier systems. Both of these will provide better information when the Symbol Tables (.PDB files) are available, these will be e-mailed to you on request.
To configure WER to generate Local Dumps for SIV navigate to the Error Reporting Setup Options (Menu->Windows->Parameters->Error Reporting) panel and press the [Set Mini Dump for SIVXXX.exe] button. You should repeat this each SIV add-on that is used. Microsoft provide detailed information.
To setup Dr Watson dumps navigate to the Dr Watson Setup Options (Menu->Windows->Parameters->Dr Watson) panel, if the Debugger is not drwtsn32 -p %ld -e %ld -g press [Dr Watson -I] which will set this up, next press [Dr Watson] which will pop up the Microsoft Dr Watson for Windows panel which is used to configure the dump options and file locations. Microsoft provide detailed information.
