Upon start up the motherboard gives a C9 error code and beeps slowly 5 times. It then boots up fine and I have no issues. I looked up the code but help center just says "OEM BDS initialization codes" and I have no idea what that means. It showed up after updating the bios on the motherboard. Looking for some insight here.

What all Hardware do you have installed on your Computer as well as all the USB Device? Set your CPU and Memory Back to Auto and run this way for awhile. I bet it is a USB Device like a Keyboard.

All items have been running at stock since I've been having issues with Apex I was having last week so I cant revert settings as they are already there. This issue showed up exactly the boot up after flashing my bios on my mother board ot the newest version. Gave it some time to go away but it has to yet after a week and a few restarts.

Sounds like you need to go back to the older bios if the issue occurred after updating the bios.

Ok, I will give that a try. Bios errors is something I know nothing about. Could this just be an issue with the bios and no hardware failures? I guess that's my main concern.

When you updated the Bios did you First Set the Bios Back to the Default Settings? If not this could be the cause of your Code C9.

It should have already been on default settings but I can do it again. It may have had the core ratio changed but I'm pretty sure it wasnt.

Yeah, it could definitely be a bios issue.

Did you reset it back Before, you have posts that you show you have overclock the CPU and Memory. But you should to one more time, remember you have 2 Bios on that Motherboard.

Oh, I did not know I had 2. Are they updated independently? Do u need to upgrade one, then the other to the same version? I honestly have never heard of such a thing so that could be the problem. I think the flash was done when the OC was set back to default but let's assume it wasnt. What do I do in that case? Reflash again with the OC off?

"Are they updated independently?" Yes "Reflash again with the OC off?" Yes but better if you just set the Bios back to the Defaults. Change the Bios to the Good one and boot up and enter the Bios then Change to the Bad Bios and re-flash it within the Bios using a USB Flash Drive. Save your Other Bios with the Current Bios on it and make sure the other Bios works. When you update the Bad Bios restart and enter the and then setup your Settings that you want to use. Why I will only buy a Motherboard with 2 or more Bios.

Interesting. I had no idea it had 2. I like the redundancy built in by design.
I'll do as you recommend once I return from field work. Itll be a couple weeks but I'll let you know how it turns out.
I'm going to assume there's a switch on the board somewhere to change between the 2 bios?

Once I get a Solid Bois on One I update the Other with the Same Settings. If you save the Bios Settings to a Flash Drive within the Bios you can copy it to the other Bios that has the SAME Bios Number. Then once this is done and a new Bios comes out you can test on one while you still have the other to fall back on. On my Motherboards that have 3 Bios I have my Working on 1st One Test on the 2nd one and my Backup on the 3rd one. Item 23 on Page 12 Support Manual for EVGA Z370 FTW (134-KS-E377)
