Windows 10 driver support for Z77 MB?

Asrock AXTU has been running on my system a few days, my only problem with it is the CPU RPM drops to 0 in spurts then back to 2000 RPM, after I uninstalled it, it seems to work normally at 2000 RPM with no drops.  I'm using HDINFOx64.

All SSD speeds change with use, as we use them more they don't perform as well as they do in the "FOB" state, Fresh Out of Box.

Unless you secure erase a SSD, it is not in its 100% unused state. A format does not do that.

A small loss of sequential speed is nothing to worry about. Plus if you first tested your SSD as an empty, non-OS drive, and then test it again while acting as an OS drive that is doing things for the OS while it is being benchmarked, the comparison is not the same.

The Intel IRST driver is both a RAID and AHCI driver. You can install it with the SATA mode set to AHCI just fine. Single drives used in RAID mode are treated as if the SATA mode is AHCI. The driver being used is the same.

If you open Device Manager, and then open Storage Controllers, you'll see the entry for the IRST RAID device:



New versions of IRST are not continuous improvements in performance, but new features and bug fixes. The fastest version of IRST is considered to be version 11.2. If you check the datasheet for the Samsung 840 Pro, the fine print states Samsung used IRST 11.2 in AHCI mode for the performance specs in that document.

If you have the Samsung Magician software installed, run it and at the very bottom click on the System Info button. Expand the System Summary entry on the left, and then expand the IDE and SCSI Controller entries. You may or may not have both.

The Magician software has never recognized RAID mode correctly, it tells you that you are not in AHCI mode, right? That is false, RAID mode has all the features of AHCI.

Regarding the chipset installers and your mouse, whatever works best for you is the best.

Besides the Intel chipsets needing an IRST driver to provide RAID, which is a given, I don't get your point.

Win 10 has the "inbox" IRST driver iastorav.sys (iastorAV) and even the older Matrix Storage Manager driver, iastorv.sys (iastorV). The iastorav.sys driver in Win 10 is from IRST version 13.2.0.1022.

How the Intel Chipset "drivers" are affecting an Nvidia graphics chip video card is interesting.

However I have noticed the program is still running only because my auto fan control presets still work. Please check this out when you guys can. System has ran flawless and still is besides a few Win 10 problems. Question if I download the Z99 Extreme Utility will that work?  Z77 Extreme4, w/ Intel I5 2500k OC 4.2ghz Corsair 750 watt  16GB Kingston Hyper X Genesis 1600mhz exact same Western Digital 4 TB Samsung 850 Evo 500 GB MSI 760 GTX 2Gb Logitech Keyboard and Mouse

Are you sure AXTU is running? The fan speed control in AXTU is identical to that provided in the UEFI/BIOS, so the settings in the UEFI may be what you are getting.

If AXTU is running, you should see it as a process in Task Manager, or as a Service.

No such board as a Z99 Extreme. Did you mean the Z97 Extreme4?

That board uses A-Tuning which will not work with your board at all. You must use AXTU.
