Motherboard bios shows 99 at bottom right corner during post

[mango]

Dear all, this is my first post and I am from Singapore.

I am encountering 99 post code since the first time set up till now. Is it normal to have code 99 appearing at bios boot screen? Read from ami manual that it belongs to super io initialisation but I am out of clue what causes it.

From other web forum others have mentioned the following and I am getting mixed answers.
1. motherboard failure which resulted in code 99
2. pcie unplug which causes the error

Those users encountering this 99 error are unable to boot to windows but the system I am running on is running perfectly fine. I believe and hope that it is a standard procedure operating code but cant help feeling paranoid as it is just a month built.

I have taken the system apart and boot minimally with only onboard vga, cpu and ram but still encountering the code 99. Reseated ram and clean cpu cooler reapplied with fresh thermal paste. I have sought to clear cmos and restore to default bios configurations and even updated to the lastest bios H11DRC16.BSS to H11DR413.BSS but to no avail. Boot up still shows error 99.

However there are no issue while normal booting during gaming or installation of windows. The problem is minimal and non disruptive but would to know of it is board issue.

Should I RMA it? The board is working great and having great fun with csgo with average 130fps. Cheers.

if its boots, odds are its fine

but id get a better board
skylake needs ddr3 1.35v or lower
if you can, return teh board and ram and get a ddr4 board and ddr4

i would never run a gtx 460 (160w) gpu on a cheap 500w psu

Glad to hear a positive reply so I shall keep in view before returning as it would be hard to justify a replacement as there isnt any issue with post. I thought fellow folks with the same board can offer some insights sharing as biostar is a rather niche board.

Yeah agreed I should get a better board but this is a secondary gaming pc on steam source based games so to give the 460 some life (cool its 6 years without a hitch) Coupled with a hardly resistable deal of 200SGD entry to skylake.

Agreed a lower tier aerocool is cheap but the 460 seems happy with it. Average voltage stability between 12.212V and 12.344 on 230V from bios reading (Within spec +5 -5V). On main pc an aerocool KCAS 700W powering Sapphire Nitro R9 390 8GB without single hitch. A personal opinion that we have to get off skepticism of lower tier power or mobo as long our power grid lines are well maintained and we strived to keep system within load specifications.

Great thanks. Cheers.

in bios its at no gpu load
when gaming the psu may struggle and kick out ripple/noise that can kill hardware

Agreed no gpu load in bios hence I ran heavyload for hours and have csgo running all night. I would like to stress the system further. Any free software other than heavyload? Does cpu usage 100% means the system on full load? On hitman absolution the GPU hits 80% with average 36ps. Thank you.

I have a similar brand of motherboard (B450MX-S) and it show also 99 on post but it always post so I don't know if it is error or not

How about you consult the manual of the mainboard instead of necro'ing a seven year old thread?

Meanwhile in 2023, I remember building this machine with that 99 code on the MB debug display. I simply removed the CMOS battery and reinstalled it. That was in the year 2017.

enable quick boot in bios, then it will skip many of the tests after the previous passed with no hardware changes

99 could mean its done and just waiting for boot drive or bio key or some user input
check boot options and turn off all unused boot devices (usb/odd/lan/other hdd/ssd)
