I am experiencing erratic behaviour from a new build i put together for a client of mine. Clean install of Windows 10 Pro x64 Ver. 1709 fully updated and latest bios 1.22. Problems happen using either the asrock provided drivers from the site or the latest drivers per device. the build is consisted of Asrock Z370 Extreme4, i7 8700k, HyperX Fury 32GB DDR4-2400MHz (HX424C15FB2K4/32), Samsung 960 Evo 250GB NVME, Western Digital Red 1TB, Gigabyte GTX 1060 OC 3GB, Evga 650 GQ, Noctua NH-D15 cooler. The computer runs at default bios settings with minor changes. -First issue is that the computer freezes while doing nothing stressfull. This has happened 4-5 times during 3 days. No stress at all. When i try to stress test it it behaves just fine, no crash or bsod, temperatures max out 61 degrees celsius and it seems fine, Ram checks out fine. I also ran several rendering sessions and it works like a charm. The freezes don's seem to have a pattern. -Second strange issue is USB related. I use a microsoft wireless 100 set of keyboard and mouse. While it works ok and i have it connected to the upper left usb 3 port, if i connect a device on the right adjacent port such as usb stick or even external hdd, mouse and keyboard stop working, but the other device is initialized and it opens. If i disconnect it keyboard and mouse work again. Same happens if i use bottom pair of usb 3 ports. If i connect the wireless adapter to the usb 3.1 port and the device in any other back panel port, all work but i get mouse lag. Same happens if i use one upper usb 3 port and one lower usb 3 port. If i use the front panel usb 3 ports connected to any of the 2 headers all work fine and no lag. This happens using both the microsoft driver and the asmedia driver. Any help would be appreciated because customer is getting angry for his faulty 1600 euro computer. I suggested this motherboard because specs seemed great but sadly it proves me wrong... |

" rel="nofollow - Hello, I also have the problem with freezes. Yesterday it happend, today I left the PC for 3 hours and came back, the monitor was still on but couldn't move mouse anymore / keyboard didn't react and the LEDs on keyboard didn't light anymore. I have very similar specs as OP. Mouse and keyboard are Cherry devices so nothing cheap, connected via USB. No more other USB devices. BIOS is 1.30. If there isn't a solution for this I will return the board.  |

All, just to close the loop, I got my system stable by - Disable C Power state completly - Increase VCCIO 1.1V and VCCSA 1.24 Gruss

 DO NOT FOLLOW THESE INSTRUCTIONS! You could fry your RAM.Then is a known bug with the Z370 Extreme4 - linked to XMP profiling. In order to stabilise this M.B you infact need to LOWER these settings - not increase them. see here http://forum.asrock.com/forum_posts.asp%3FTID=6860&title=z370-extreme4-xmp-bug" rel="nofollow - http://forum.asrock.com/forum_posts.asp%3FTID=6860&title=z370-extreme4-xmp-bug Have read - see tried and tested workaround. Oh and update BIOS to 1.6 aswell - or at a minimum DO NOT USE 1.3 or 1.4 versions. ------------- alchemist83 |

I had problems with power off and restart - the PC screen turns off, but the PC not stopped/rebooted. Bios upgrade to 1.30 solved the issue.
