I guess I have a few questions, leading to one concern about this board (990FX Extreme 4). It's about sensors, and possible hw faults. This is a relatively new board - ~2 weeks in service, and I get strange/no readings from several programs.
Everest 5.3 Misreads all voltage, except CPU Core (12V, 5V, etc read as ~0.05V). It displays nothing under the "SPD" or "Chipset" headings. I understand that this program is out of date, but it's portable, and I like it, and this would be the first system it's failed me on. But again, I understand if it's just too old to work anymore.
SIW v2011.10.29n will show ridiculous fan speeds It commonly shows fan speeds that are way out of whack (20-60,000 rpm) for connected fans, and 10-200 rpm for fan headers that are unused. It also gives a temp for "auxtin" that ranges from 70C (under load) to 170C (idle) - yes, the reading goes down when I start p95, or FAH. HWInfo64 agrees with SIW. (On a side note, I typically have a 10C difference between CPU and Core temps, as others have mentioned.)
Everest, SIW, and HWINFO64 all agree that my FSB is unstable, varying by as much as 30 or 40 MHz. First, I thought it was only when FSB was elevated to 220MHz, or so. But even at stock, it dips to 190 sometimes. (C&Q is disabled.)
Everest, SIW, HWINFO64 and AXTU (Asrock Extreme Tuner) regularly report the CPU fan dropping to 0, thought I can plainly see it spinning. This, plus some other assorted wackiness, has me concerned about whether there is something wrong with this board. I'm hoping someone with more experience can enlighten me.
Also, it seems that my board ignores voltage settings made in BIOS - the machine starts with 1.325 VCore no matter what I set, although I can change it using AXTU. BIOS settings for RAM seem to work properly.
Thank you for any help anyone can give.
