CPU upgrade, no POST

[idle pasture]

Evening everybody.

So I’ve been stuck with an issue for some time now. I am willing to pay GOOD money for some help.

Last month I bought the RYZEN 7 9800X3D, when I installed it, I had no post. I did everything, absolutely everything. I installed the correct BIOS update, switched ram slots all of it. Everything.

I sent the CPU back thinking it was a DOA CPU, and now I’ve received my replacement. It still doesn’t POST. I have done and tried everything. Please someone, for the love of God help me.

Specs: RTX 4070 Super
RYZEN 7700X (previous CPU)
32GB RAM
1000W PSU Corsair I believe it was.
B610H 3DS

If anyone has a response, please, ping me as much as you need to.

First thing to try - putting the old CPU back in and see if that posts

[idle pasture]

Alright tried. It does post.

[hybrid pilot]

what is your exact mobo and what bios do you have installed?

[idle pasture]

The motherboard is B650M DS3H and the latest one.

Very latest, forgot the name. I can fetch it for you if you wanna.

Three updates ago, they added support for the 9000 series.

[hybrid pilot]

this is possibly something you could try doing (if you havent already)

[idle pasture]

I just relaunched my PC for the first time after re putting my original CPU back in.

I got this opening BIOS. What does it means

Mean?*

[hybrid pilot]

i think its just reset bios options, so you may need to turn on amd expo and rebar

[idle pasture]

Ah, gotcha. In regards to the previous picture, what’s in step 3?

I see that I have a Q Flash option for when I wanna update my BIOS.

I’m unsure if there’s anything physical on my motherboard I can press, if that’s what you’re referring to.

F32f. That’s the latest version.

[hybrid pilot]

it should be on the IO on the back of your pc

[idle pasture]

The back of my PC is a huge mess of horrible cable management, you mean to tell me I have to take out the motherboard to reach that? 😟

Oh, wait timeout. When you say the back, do you mean the right side of the PC or immediately in the back where my HDMI goes in?

[hybrid pilot]

here on the back of the PC, not the back of the motherboard

sorry, shouldve made it more clear

[idle pasture]

Ah!

[idle pasture]

No no, don’t apologise. Let me see if I can find that.

[hybrid pilot]

What i sent is a way to update the bios without installing a CPU

[idle pasture]

I see a small circled “Q Flash Plus” button!

[hybrid pilot]

yep, thats the one

[idle pasture]

Wonderful.

When it is appropriate for me to press that?

When it’s not booted, in bios or with the new CPU installed?

You say jump, I ask how high. Take all the time you need, and thank you again!

Oh my God, I must be a total idiot. You’ve already told me.

I gotta install the new update again on a USB, plug it in, rename and then press it?

[hybrid pilot]

i was typing out the instructions but this may be a better help for you

https://youtu.be/Qf7fZhzotA0?feature=shared

[hybrid pilot]

luckily this video is the exact same board as you

[idle pasture]

Wonderful!

I will watch it fully, follow through and report back to you. Thank you. ❤️

[hybrid pilot]

Alrighty, not saying that this will work but it is something to try

[idle pasture]

Given that I’ve tried anything, believe me, anything will come as a surprise.

This one I haven’t tried before though, so fingers crossed.

[hybrid pilot]

also, if youre not yet past the stage, there is a newer F32G

[idle pasture]

Yup! Already saw it and got it downloaded! 😁

[hybrid pilot]

alright, lemme know how it goes, and remember (if you already haven't) to format the USB and rename the file

[idle pasture]

Alright.

And we’ve begun..

[idle pasture]

Made sure the USB was FAT32, renamed the update, plugged it into the BIOS USB port.

Should be doing its magic.

Heard the guy say it can take 15 minutes.

[hybrid pilot]

Yeah, you don’t have the CPU in right? Just the cooler on top

[idle pasture]

Oh, no I have my CPU in.

Actually got confused by the video cause he said that the CPU wasn’t a necessity, but he still smacked in the CPU.

The flashing stopped, the fans got loud, still no POST as of right now.

[idle pasture]

I can repeat the process if you’d like, all I gotta do is just take out the CPU.

Sorry for the misunderstanding.

[hybrid pilot]

Oh, no it should still work with the CPU, it just can work without it

[idle pasture]

Ah gotcha..

But my, my. Still no post. Should I still give it some time even after the flashing has stopped?

God, this is gut wrenching..

[hybrid pilot]

Quick question, what capacity is your USB stick?

[idle pasture]

32GB.

Or, no I believe I grabbed the 15GB one. Sorry, I have two.

Yeah, straight up no post still.

[hybrid pilot]

as long as it’s under 32GB, FAT32 will work. Possibly try your Old CPU again and see if the update actually happened

[idle pasture]

Sigh

The most tiresome part of this thing is the removal of the fans and the CPU. 😆

Alright! Here goes, let me re install the other CPU

[hybrid pilot]

Yeah, sorry if this is a pain - but it at least makes sure that everything is still working

[idle pasture]

You’re absolutely right.

Alright let me turn off the PC and reinstall the part

[hybrid pilot]

Alright

[idle pasture]

It seems to have worked, update wise. I got the boot failure screen too.

[hybrid pilot]

Alright, so it’s still posting with your old CPU but not your new one

[idle pasture]

Great, and now I’m stuck on the screen. Can’t pick an option.

This is a known bug, I forgot the workaround for this.

[idle pasture]

Correct

Ah, I remember the workaround.

Yup!

F32g is installed

[hybrid pilot]

Is there any damage on the 9800x3D?

[idle pasture]

Hmm…. What could be the reason.

[idle pasture]

Nope, straight out of the box.

Pins on the MB is looking good too.

I returned the previous one because I was getting the same response. I highly, highly doubt they sent me a DOA twice.

There’s just no shot. I cannot believe that.

Is it dangerous to clean out the firmware from the BIOS somehow and reinstall through Q Plus?

Nah.. But that doesn’t make sense either.

The BIOS update is there, CPU is in healthy condition.. Lord.

[hybrid pilot]

I don’t think it’s BIOS, if it’s updated and your old CPU is still working, there shouldn’t be an issue

[idle pasture]

Yeah accurately. So we can rule out BIOS, we can rule out MB, I can’t imagine it being the GPU, I’ve already attempted swapping around the RAM sticks in position 2 and 4, took out the CMOS battery..

What else could be the issue.

[hybrid pilot]

I’ll be honest, it is really strange that it still isn’t working. I’m looking into some other threads I’ve found of people having the same issue, I’ll see if I can find another potential fix there

[idle pasture]

And I’ll reciprocate the honesty, I’m willing to bet it’s something super minute that’s just hindering it from posting. This is always what happens.

[hybrid pilot]

How long did you leave the CMOS battery out?

[idle pasture]

15 minutes.

[hybrid pilot]

Could it be possible that your pc is memory training? They generally do after a new CPU is installed

Especially if you’ve moved the RAM around too

[idle pasture]

Yeah, I highly doubt it.

I’ve left the PC on for more than 30 minutes previously. Didn’t post.

Then I left the PC running all night. Woke up next morning and it still wasn’t posting.

All of this didn’t happen today of course.

You ever encountered something like this before?

[hybrid pilot]

Personally never upgraded a CPU - i'm still on my first. I have seen people have an issue where the CPU won't boot, but it is usually fixed with a BIOS update

its just strange that the new one still doesnt work

[idle pasture]

Oh, well there you go.

Yeah, you hear a lot about boot fails when installing new CPU's but I've never seen alike this magnitude.

[hybrid pilot]

in your bios do you have AMD expo turned on by any chance?

[idle pasture]

I do not recall. Shall I reboot into BIOS?

I think it might be, but let me make sure for ya.

[hybrid pilot]

alright. I've found something with a fix where someone had the same issue as you where it ended up being the ram stick

[idle pasture]

Hmm.. Alright, well EXPO is turned off.

Sure thing. What would you like for me to do with the Ram?

It’s a bulk ram, let it be noted.

[hybrid pilot]

the step-by-step that i've found says:

1. Remove RAM and CPU, then install new CPU
2. Remove CMOS battery for 10 minutes, then put back in
3. Install the RAM stick into the 2nd slot across

[idle pasture]

OH MY GOD NOT THE CMOS AGAIN 😭

I’m finna have to remove the GPU fo dat one 😭

[hybrid pilot]

ill be honest, i don't think it is the CMOS in this case

since youve done it once

[idle pasture]

Me neither, I’ve already done it before

[idle pasture]

Yeah exactly!

[hybrid pilot]

do you know what ram stick it is that you have?

[idle pasture]

Yeah lemme check for gab

Ya

[hybrid pilot]

nevermind, its teamgroup 32GB 6400

got it

[idle pasture]

Yup!

Alright so, remove the ram and CPU, then reinstall the new one again and this time in 2nd slot?

[hybrid pilot]

yeah, but first possibly boot into BIOS, turn off ddr5 auto booster, then try the new CPU

[idle pasture]

Yeah I have that on. Lemme do dat.

[hybrid pilot]

I know AM5 was a bit (or may still be) iffy with DDR5, so possibly having that on with a new CPU could cause potential issues

[idle pasture]

Yeah very possible. Welp, let’s give it a go!

Wait.. So I basically just relocate the ram to the 2nd slot already from now, reinstall the CPU and boot?

[hybrid pilot]

yeah, make sure pc is properly powered off with electricity discharged, Install the 9800x3D, move the RAM to the second slot along. Also worth plugging your display cable straight into your motherboard and seeing if that helps

[idle pasture]

I believe I’ve already done this before, but I’d gladly give it a go again.

[hybrid pilot]

alright, let me know if it works or not

[idle pasture]

You got it partner. BRB

Alright! Moment of truth o

Let me plug the DP to the motherboard

OH MY GOD!!!

OH MY FUCKING GOD

[hybrid pilot]

I’m guessing it worked?

[idle pasture]

IT ACTUALLY POSTED!

[hybrid pilot]

Great. Make sure you can boot into windows

[idle pasture]

Bandooka THANK YOU

[hybrid pilot]

If you can, it may be that the DDR5 auto booster or the RAM could’ve been the problem

[idle pasture]

It booted fully!

[hybrid pilot]

No problem!

Open task manager and see what speed your RAM is running at

[idle pasture]

You got it! Just a moment.,..

Here ya go!

I ran my RAM cleaner, it's up to 25GB of availability.

[hybrid pilot]

Looks like your RAM is running at max speed, so no more issue there

Don’t forget to change back to your GPU output if you haven’t already

[idle pasture]

Is there anything you'd like for me to do in BIOS?

In regards to CPU profiles?

[hybrid pilot]

Make sure resizable bar is enabled and enable EXPO

[idle pasture]

What if there's no profile in EXPO?

[hybrid pilot]

I’m pretty sure there should be a default profile you can use

[idle pasture]

I can only see a "Disable" button.

[hybrid pilot]

Can you send a pic?

[idle pasture]

Yeah, let me reboot!

[hybrid pilot]

Oh if you mean here, that’s just showing that it’s set to disabled. You can press on it and some profiles should show up

[idle pasture]

All I can see is disabled.

[hybrid pilot]

strange, do you mind if i can see a pic of the whole BIOS screen?

[hybrid pilot]

are you able to toggle the settings under where it says AMD expo? im presuimg not

[idle pasture]

Yeah, I can’t.

[hybrid pilot]

its not much of a problem - its possible that it doesn't work on that board using single channel. Other than that though, i would say turn on X3D turbo mode and you're all set

[idle pasture]

All good man, I’m beat anyways. This help was more than enough!

Thank you, thank you, thank you! 🌹

[hybrid pilot]

no problem whatsoever! have fun with your now working 9800x3D
