Bios ignores settings

[Poohl]

Hello.

I changed my FSB from 234 to 237. Next my PC booted as usual, but with a FSB of 200. Since then it doesn't apply any FSB changes anymore. Everything else I tried is working (Voltages, Boot devices).

Has anybody an idea what to do to regain control about the FSB?

Do you know if the CMOS battery is dead?

check cmos battery

maybe it can't do it? ( won't work )

or, did you actually save the settings once complete?

cmos battery : 3.088V

I changed the FSB back to 234 and it still didn't apply the changes.

reset cmos. see what happens. then try another over clock, see what happens. again, maybe there's something not "mathematically" correct and it won't do it.

what is the voltage corrected?

I had a similar problem with my z87 board.  No matter what I did it would not remember the settings.  I ended up giving up on the bios and overclocking using a Windows utility (gigabyte's easy tune).  Only problem was it reset after reboot, so it still wasn't a perfect solution.

Resetting the cmos helped, but it now takes multiple reboots to apply FSB changes.

Current (working) FSB: 230

Cmos Voltage: 3.06 (read from Bios)

Vcore : 1.088 - 1.200 (CPUID)

run one stick of ram in farthest slot from cpu. retry oc.

That is similar to what mine was doing.  Cpuz and hwmonitor would both report that the multiplier was changed, but still reports the max stock frequency, and the performance wouldn't increase.  Interestingly enough, the voltage settings WOULD save, so I got the (non)bonus of running hotter at the same speed!  Tried replacing cmos, flashing bios, all different ram combinations, asking for help in forums, et cetera.  Nothing worked, so I settled for the utility in Windows.  Good luck, and I hope you do better than I did in figuring it out.

OK, I fixed it.

I resetted the Bios and set the first Boot device to CD. I don't know why this worked bit it did. (It now tries twice to boot from CD)

 

Thanks for helping.
