Sometimes my posts can be TLTR. I'll really try and keep this short. A lot of the background to this can be found in "Memory And Storage" -- a recently active thread started by me about "Intermittent" random shutdowns and crashes in a time-series that might actually have made the problem source harder to diagnose. About 14 crashes, the average time between them was about 14 days. It appeared that the problem was the motherboard -- which had been an open-box purchase last year. Instead of building new with Rocket or Alder Lake and an appropriate motherboard, I just wanted to get the system fixed after a careless episode with a static charge and a vaping-pen charging in a front-panel USB port. To enumerate, there was the original board, the defective open-box replacement, and the RMA replacement that came from ASUS. I am now setting up this third motherboard.
I've been diagnosed with cataracts that require surgery in my left eye, and I've been more and more annoyed at what seemed like the ineffectiveness of my most recent eyeglass prescriptions. I have to visit the eye-surgeon end of this month to proceed with the surgery, eager to retrieve my pre-cataract vision. This, of course, has made it harder to perform a motherboard replacement. But it seems to have been done, and I'm setting up the BIOS.
While all boards may seem to have minor quirks and obstacles in completing a BIOS setup and configuration, I'm familiar with this make and model mobo and its BIOS. ASUS may have given me the latest BIOS revision for my Sabertooth Z170 S, and I notice differences -- some of them positive -- in how the system posts and (thankfully) boots.
I at first worried that I might have to resort to another Z170 board I picked up at EBay in my panic last year to get things back up and running -- an ASUS Z170 WS workstation board. Like the starter cartridges the characters in the "Flight of the Phoenix" used to start their makeshift airplane and get out of the desert, the workstation board is my last resource. I don't think I'll need it.
However. When I brought my box back into the house after the board replacement so that I could fire it up and test it, it would stop at boot-time with a message suggesting "Hit F1 and enter BIOS -- No CPU fan or minimum fan speed set too low". Not the exact wording, but that was basically what it said.
First, I discovered, because of my eye-sight, that I had connected the two CPU fan connections (one to a PWM bus) to "CPU_OPT" and "Water Pump". So I corrected that.
But it would throw the same error again. So I began to look at "Q-Fan Configuration", finally setting the minimum fan speed to "Ignore". Then, everything was fine. The BIOS didn't revert to its default settings, it kept my changes. I could shut down the system and boot up with no problem whatsoever.
But I had never seen this before. I'd usually set the fan-speed minimums to the largest value of 600 RPM.
Any ideas about what was going on with that? I've never encountered it before. But they wouldn't have put an "Ignore" option in those BIOS items unless it was a viable choice, and setting them up with "Ignore" still allows me to set fan curves in BIOS. System seems to boot up and run fine now.
It could take two weeks or longer to verify that I did indeed diagnose the correct part, but it is not likely anything else. I know that the cold startups and restarts occur in a way that gives me confidence over the original board used to build the system. It seems like this could be a sweet-running system, and I can move toward building a Z690 system later in the year -- after my eye-surgery.
