siv system information viewer siv system information viewer siv by ray hinchliffe system information viewer is a general windows utility for displaying lots of useful windows network and hardware info cpu info pci info pcmcia info usb info smbus info spd info acpi methods machine info hardware sensors networked computers operating system information and more siv is designed for windows 11 10 8 1 8 0 7 vista xp 2022 2019 2016 2012 2008 2003 2000 nt 4 00 and nt 3 51 windows 95 98 and me are also supported core i9 ryzen 9 core i5 intel xeon extreme via centaur dec alpha amd epyc itanium 2 powerpc machine wi fi processors menus chipset mch cpu usage network pci bus usb bus disk smart volumes battery windows cpus download mirrors please download siv zip from a mirror site filecroco official mirror filehorse majorgeeks oldergeeks softpedia or sooftware com current release download after downloading siv zip you should use siv64x exe on 64 bit windows x64 siv32x exe on 32 bit windows 2000 x86 and later siv32n exe on windows nt4 x86 siv32l exe on legacy windows x86 siv64i exe on intel itanium servers siv32a exe on digital alpha windows and siv32p exe on powerpc windows systems if you find siv useful please consider making a donation towards its development siv is free for home use but if you wish to use it commercially then contact me for further information current release changes version 5 87 released on 14 may 2026 improved dual single channel memory reporting for early amd athlon 64 cpus such as manchester and toledo resolved issue with sort on menu file save save selected added abit bx6r2 0 dfi lp nf4 msi ms 7a94 x299 raider motherboard support added windows 11 26h2 build 29585 support enabled operation of acpi eval etc history current and all previous release changes visits known issues none siv support forum the siv support forum provides help with using siv and can also be used to report issues or request new features for some issues a better option may be to e mail the details along with the siv save local menu file save local files as this often means it s far easier to address issues with most issues a siv beta is usually released within a few days which resolves the issue or adds the new facility aio device control guide before using siv to control aio devices you should read the guide and in general this may be useful as it also contains sections about siv setup and usage if link devices does not list your aio devices then check that they are supported by siv listed on the usb bus panel have no i o errors they are reported by devices and printers are in the device manager hid human interface device or usb universal serial bus sections and there are no errors yellow triangles does a device come and go on unplug and re plug the usb cable or sata fan header power connector if you wish to use siv to fully control your aio devices then you need to specify the aioctl command line qualifier typically using a shortcut when aioctl 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 typically you need to provide screen images of the siv initial screen usb bus link devices link status link fans link leds and link setup panels siv stores the configured aio hardware settings such as custom cooling curves in the windows registry and you can use menu machine siv setup siv setup aio to view this this configuration is setup in the hardware when you start siv and specify aioctl for the link fans and link leds 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 aio device reporting and control is only about 4 of siv and finding the aio link panels can be tricky for new users they are all accessed by the tools sub menu menu tools link or via the sensors split button drop down menu all the aio link panels have buttons to directly access others when siv does not find any aio devices only the link devices panel will be available siv issue reporting in the rare 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 and later 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 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 lock usage page displays the namespace the locks are currently within and lock handle displays the programs using the locks when only siv is reported this shows no other programs are using that lock so if other programs are reporting motherboard sensors their access will not be interlocked with the siv accesses so the strange and unexpected may occur all of aida64 cpuz hwinfo ohm speedfan siv should correctly use these locks and work correctly when used concurrently asus ai suite does not use these locks so should not be used when siv is being used and doing this is unsupported this is also the situation for most other motherboard manufacturer supplied utilities 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 0x7e 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 if the smbus scan causes a reboot or lockup then the command siv dbgsmb save initial smb bus pmb bus siv_dbgout txt siv_dbgout log more should be used to find and then report the issue the last line of siv_dbgout log will indicate the smbus slave address causing the issue and once excluded then the issue should be resolved 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 siv_dbgout txt siv_dbgout log more should be used to find and then report the acpi method causing the issue the last line of siv_dbgout log will indicate the acpi method that caused the issue update program downloads mondevs zip monitor id definitions update program mondevs txt monitor id
