Question Flashing a bios

Apr 10, 2021
CPU: i5-9600k -> i9-9900k (R0)
Mobo: Gigabyte Gaming SLI (ver F4)

Okay so I recently upgraded my cpu, pc posted, no issues on the first boot. I restarted the pc for a random software update, the pc went to a bios system repair, froze, and the fans started spinning at an insane rpm so I turned the pc off. Tried to boot again, but I fat fingered f12, opening the boot menu, which it allowed me to boot into windows, however XMP is disabled. At this this moment, I can still get into windows but my RAM is clocked at like 2133hz. Which is kind of annoying, I'd like to fix it obviously. After looking around I noticed my i9 stepping is D which is different from what is listed as compatible on the manufactures website. From memory I think ver F4 support i9-9900k w/ P0 or something. I'm not really familiar with cpu stepping or what that is about (feel free to educate me, I'd like to be less clueless), do you guys believe updating my bios to a newer version is worth the risk? I've never updated my bios before on top of the fact its crashing on the repair tool; I'm scared to brick my hardware XD

Thank you for your time and help <3

Risk? Flashing the BIOS hasn't been "risky" for years and years, unless you fail to arm yourself with adequate knowledge of what you are doing and just start trying to do stuff with no idea of how it's actually supposed to be done.

So yes, it's "worth the risk", because in reality there almost ISN'T any risk these days. This isn't the old days of legacy BIOS where it was fairly common for a BIOS update to fail and brick the board. It can still happen, but rarely ever does unless something is not done correctly in the process OR somebody gets too impatient and powers off the system before the update completes. Generally, it's a fail on the part of the user if it happens on modern hardware.

Are you able to get INTO the BIOS if you do a hard reset?

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, IF the problem is related to a lack of video signal, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.

Trying a different monitor as well, if possible, is also a good idea if there is a lack of display. It happens.

I'm sorry I totally forgot to mention; I tried clearing my cmos, and I did get Load optimal default screen. When I selected the first option, it did the same thing as before where it would start the wheel on the system repair screen, then it would freeze. I guess I could try the hard reset and see what happens.
