Don’t underestimate a BIOS update (Ryzen 5000 series)

1 : Anonymous2021/03/20 06:47 ID: m91jey

So over a month after finishing my new Ryzen build, I finally think I figured out the random crashes, freezes, and constant USB connecting/disconnecting plaguing my system. I was very close to doing an RMA on my CPU and MB, as this seemed to solve similar issues on a similar setup.

Specs: Ryzen 7 5800x -- ASUS Prime X570P MB -- Corsair Vengeance RAM ( 2 x 8GB ) @ 3600mhz

Main issues:

-Computer randomly crashing and freezing (especially in idle)

- RAM not able to achieve 3600mhz (even in DOCP) without crashing or computer not being able to post ( No errors in memtest)

-CPU running pretty hot at idle (55c)

After flashing to the most recent BIOS on my ASUS Prime ( version 3602 ) the issues have seemingly disappeared. My cpu runs idle at 32c now, no crashing, freezing, or random restarts on desktop or when streaming videos. After flashing to new BIOS, I reset RAM to DOCP and it worked like a charm ... 3600mhz no problem. My computer has been running for over a day now without a single issue or restart.

I just wanted to document this so that it may be able to help someone with similar issues on a new 5000 processer.

In every support ticket i ever opened (i work in IT helpdesk and open a lot of them), the first thung they tell you to do i update every driver and the bios. Sometimes even drivers that have nothing to do with the problem help solve it. A nice example: new laptop doesn't get network over a new usb-c dock. The audio driver solved the problem, not the usb-c driver or ethernet one. Because computers.

I updated every possible driver I could.. For some reason, at the time, I just didn't think an older BIOS version could be causing such issues. I also thought that given the x570 boards are compatible with the new 5000 series CPU's, a BIOS update wouldn't really be necessary. I believe I was about 4 BIOS versions behind.. =/

ID: grm6ns2

If anything, a new chipset and new CPU need BIOS updates the most.

ID: grkopon

I almost cried when upgrading 3900x to 5600x and the system wouldn’t post. Turned out that my x570 MB needed a bios update to support the new chips.. wasted a couple days investigating all sorts of other things!

ID: grkxred

Mate, have a doubt. I have a board that comes with "5000 series reqdy" and I put my 5900x on the MB and work fine for 3 weeks. Then some crashes and high temps. What should I do ? Im new to these. Im in the way of learning

ID: grkrzos

When I worked in repair, sometimes the problem was even fixed by reflashing the same version BIOS.

ID: grkz9vb

I've encountered that before. Tried everything - even pulled the battery and left it unplugged overnight. Accidentally reflashed the same version and all the problems vanished.

When updating bioses on ryzen 5000 you have to keep track of the following voltages cldo vddp, vddg ccd and vddg iod. Take a picture on Zentimings if your system is stable so you know what to get back to.

Bios updates often change these voltages without any warning explaining the random crashes or audio / usb bugs

4 : Anonymous2021/03/20 10:00 ID: grkr324

In my 3950x, randomly BIOS decided that CPU temp was -122º, so why bother turning on fans? BIOS update fixed that, so yeah, keep your BIOS updated!

My friend bought a prebuilt PC couple of months ago since it's the only way to get a PC in this climate. It came with a 5900x and it was crashing left and right. I helped him update his bios and it's been running smooth ever since. Amateur PC vendor... The X570 MB pre bios update is for the 3000 series not 5000.

6 : Anonymous2021/03/20 11:45 ID: grkxb7w

Yeah, updating to the latest BIOS is pretty much a must if you're running 5xxx series. I had similar experience where my PC just wouldn't post if I had DOCP enabled, I'd get a RAM error and had to clear CMOS several times. I noticed my BIOS was the first version to actually support 5xxx series CPUs so I updated to the latest, and it worked like a charm. Temps are a little better now too, but still hitting high 70s, which I guess is normal for my cpu and cooler combo.

I have a Ryzen 9 5900X on an (Gigabyte) Aorus B550i Pro Ax mobo.

I tried... every... single... released bios (yes, including all the betas). Still getting random BSODs at Idle, and the only way getting a stable system is to do a VCore offset of -0.1V. I am really starting to think about a possible RMA, but current stocks would basically mean I will be about my working station CPU for a month, and probably would just get my money back instead of getting another 5900x.

ID: grlc627

Using the High Performance power profile has fixed things here since a couple months.

ID: grlffc2

this was something I tried before updating BIOS and it made virtually no difference with a 5800x.

glad that worked for you.

ID: grkrihq

sucks to hear man... I never got any BSOD's.. but could be a possible indication of hardware issues? as opposed to software. I really don't know though. Bottom line is, you really shouldn't have to alter Vcore settings at all just to have a stable system.

Have you tried using a different CPU?

ID: grktlbg

Yeah I've already reinstalled windows, tried other components (only the Mobo is the same, but didn't have any kind of issue with a 3600 inside it before I got the 5900x). So either it is a BIOS issue, or just some badly binned 5900x which should have been a 5600x instead.

I probably just wait for the next stable giga bios (although they are suuuuuuupeeeeer sloooooow) and if the problem still persists I just call my vendor for an RMA and if they cannot swap it to another 5900x, I just go and buy a Zen 2 (3700x or 3900x) or a 5800x.

ALWAYS keep your BIOS updated.

It improves security, compatibility and performance.

ID: grkloi0

Y'all need to decide your messaging cause it's a split from this and "don't update bios if everything is working Fine"

ID: grkn74y

I've learned over the years, that no one really knows what's best when it comes to computers

ID: grkqlo3

Tbh, this was mostly the case until z couple years ago. Most BIOS updates used to be very very minor changes, and not really doing anything. Then Ryzen came, and has updates that improve performance and compatibility (it's a newer architecture). There's also BIOS flashback now, which might sometimes help recover a bricked BIOS, it makes it slightly safer.

ID: grkvgfw

Actually decreases performance on Haswell with spectre updates

Man, that must be a great feeling. 🙂

I updated my Gigabyte Bios recently and feel that random restarts have stopped occuring.

ID: grki503

really is lol .... I was so close to taking the entire system apart and giving up

ID: grki9dp

Enjoy it, friend. 🙂 Appreciate when things are working the way they are supposed to and don't take it for granted!

I still have these issues with an asrock board I hope a bios update is released soon

ID: grkjok2

what cpu and RAM speed?

ID: grkjyq7

R5 3600 3200mhz

ID: grkk39h

It sits at 43c idle but I did notice a bios update that came out this month so ill have to try it

ID: grkkmb8

Check your SoC voltage. If it's .920mv, bump it up to .950mv. ASRock undervolted it.

ID: grln6en

Yeah ill check i just did the 1.70 bios update so hoping that fixed somethings as well

ID: grlbc12

What motherboard?

Did you search /


ID: grlm6r5

B550 hdv

Going to update my bios today. Ive been having weird issues when starting up and sometimes the vga error light will light up and it will randomly boot without problem after i force restart it lol

ID: grlefv0

before updating BIOS, VGA and DRAM were both lighting up on my MB at one point or another..depending on what I was adjusting in BIOS.

ID: grlvyzu

After i updated mine, no more weird errors when booting but my idle temps didnt drop much. Thats ok though, it doesnt go over 70c under loads so im happy.

alot of people might be running beta bios fw.

X570 was an existing platform made for Ryzen 3000 & was made compatable for 5000 via a beta update. So I advise everyone check their BIOS Firmwire to ensure it’s at the very least on a stable FW version.

13 : Anonymous2021/03/20 12:28 ID: grl0dh2

Man, I have been having some issues with DOCP (can only get my RAM to 3000) on the same motherboard. Might try an update.

14 : Anonymous2021/03/20 14:30 ID: grlbi7t

That's rough bud, glad you posted this as bios updating is extremely important, and other should know!

To put the importance into perspectiv, I have the same specs except more vengeance 3600mhz ram, but I haven't had any issues since I got the 5800x in January. I've updated the bios to every latest stable build and everything has ran smooth. PBO and ryzen master were a bit messed up at first but now work as they should.

15 : Anonymous2021/03/20 17:59 ID: grlzhit

I usually just set manual timings for the main four timings and voltage and auto everything else, I don't OC at all because I think it is the devil.

16 : Anonymous2021/03/20 08:55 ID: grknkk4

Wish I could say the newest bios worked for my 5950x

It still crashes with 3600mhz ram, random reboots etc

ID: grkob7n

are you using DOCP or manually inputting your RAM specs into BIOS?

17 : Anonymous2021/03/20 10:42 ID: grktfae

I returned an MSI B550 motherboard because it kept giving me black screens. Probably would have been fixed with a bios update but I wasn't going to wait so I got a new Gigabyte one and ot works like a charm.

18 : Anonymous2021/03/20 12:06 ID: grkyr6m

I've had to up my memory voltages again since the new bios for it to be stable but I'm pretty happy with the results

19 : Anonymous2021/03/20 12:30 ID: grl0je7

For real. The only issue that I had was my RAM would not hit its rated speed at reasonable timings. And 2 of my 4 slots did not work. (This is with a Taichi X570 and a 5900X). Updated the BIOS and everything now works. Full speed RAM, 4 working slots.

20 : Anonymous2021/03/20 14:48 ID: grldh9s

just a quick update:

just got home from work after leaving computer on idle for another 12 hours... everything was just as I left it... 0 crashes. My computer constantly crashing in idle was one of the biggest issues I had, so this is extremely reassuring.

I really think this solved my issue.

For those of you who haven't, I hope updating your BIOS solves your issues!


21 : Anonymous2021/03/20 17:10 ID: grltrga

Also don't underestimate just how shitty these manufacturers are at software.

I've never had a single issue with many Asus boards, but boy oh boy when I switched to Gigabyte, holy moly... I must've done a fresh Win10 reinstall about a dozen times before I figured out it was their shit software.

Soon as I uninstalled it all, no more random freezez, crashes, cpu spikes, etc....

22 : Anonymous2021/03/20 18:09 ID: grm0o15

I personally got my 5950x at launch and it was unstable (random restarts at idle with whea errors in even viewer) i tried every new bios since then, the newest 3302 with agesa its the most stable but it still restarts. It used to restart every hour with default bios settings, then it improved to couple of hours and with newest it restarts in a couple of days. I said enough and rma'd my cpu now, waiting for a replacement.

What i wanted to say is its good idea to wait for couple of weeks for bios releases but if you still get issues dont waste your time and just rma it (not counting running above 3200mhz ram, only at official supported specs.)

23 : Anonymous2021/03/20 22:34 ID: grn1298

3700x build on a b450 mobo. I have the random crashes usually when im playing runescape and watching vlc player vids at the same time.

usbs sometimes act a little funky.

temps are mid 40s idle

load around 65c.

I have already updated the bios hoping for a fix but no luck.. at a loss for next steps.

25 : Anonymous2021/03/20 10:02 ID: grkr6c8

Question: why don't BIOS manufacturers support updates by saving BIOS settings or at least user changes in a format that can be exchanged between BIOS versions?

The fact that they haven't managed to address the requirement, or to implement it, over the last 40 years, proves the immaturity of their software development and doesn't bode well for the quality of the rest of the software.

26 : Anonymous2021/03/20 10:21 ID: grks7h0

How do you mean doesn't bode well for the quality of the rest of the software? If no one does it then you can't really surmise too much else from that, can you?

27 : Anonymous2021/03/20 11:21 ID: grkvp6x

it sounds like you need an rma

28 : Anonymous2021/03/20 11:57 ID: grky3ua

He was prob running a Beta BIOS like what?
