5900x nightmare

[steeno78]

Ok so my partner treated me to a brand new Ryzen 9 5900x for my Birthday which I was over the moon about. I paired it up with my MSI B450 Pro Carbon AC and everything was good, for about 10 minutes then black screen, fans running and lights on but no video output.

 

I done troubleshooting on all the things I could think of, gpu, mobo settings, etc. But same outcome everytime, any load on the CPU ended in black screen.

 

I bought an MSI MAG x570 Tomahawk wifi, thinking maybe my motherboard was defective but I get the same outcome. My power supply is a corsair 850 watt, so I know it's not power, my RTX3060 isn't very old only about 6 months old. My ram is corsair vengeance lpx 3200 32gb.

 

I read forums until I was blue in the face and only one suggested fix worked but it massively reduces the potential power of my CPU by fixing the chip to 4400mhz and turning pbo off and underclocking the voltage of my ram. This fix worked on the Pro Carbon board but doesn't work on my Tomahawk.

 

Anyone any ideas as I'm all out, all I can think of is to RMA the chip.

Update BIOS first. Especially with an older board. There were a handful of DOA 5900Xs but if it worked to begin with, this sounds like something minor.

 

ADDED: Corsair RAM and Ryzen do not play well together as of late. I'm thinking it's certain generation Ryzens but while I haven't quite nailed it down yet, there is a pattern of it. You might want to get your hands on some Crucial Ballistix or some other compatible RAM certified for the board and processor (5900X handles up to 3200 Mhz).

The BIOS that's in the board is the latest non-beta for the board, I thought of that as I know some of those beta versions can be slightly buggy. But the version I have is the newest stable version

The latest non-Beta is 7B85v1C from 2020.

 

*I’d look into it further but I’m running out. The support page for that board has a compatibility chart. 

 

 

[steeno78]

The newest is 7C84v19 released in 2022

[steeno78]

That's for the Tomahawk board

[An0maly_76]

BIOS isn't the only factor in the equation, however. 5900X can get quite toasty, and they demand bigger, beefier coolers and good VRM cooling, so I honestly would not run one on a B450, and only a few B550s, though I am told that a lot of newer B550 VRMs are so efficient they don't need cooling.

[steeno78]

Yeah that's another reason I moved to the x570 board as I read that also

[steeno78]

I have the chip water cooled and when it allows me into the bios it runs around 33-36 degrees. Even when I get to the os it seems to idle around 40-46 degrees. It never exceeds a safe limit it's just so frustrating lol

[steeno78]

If I put the Ryzen 5 3600 everything runs perfect it's only if I reinsert the 5900x I get the problems

[An0maly_76]

40-46 idle isn't terrible, and they are prone to fluctuation. They're rated safe to 90C. Mine runs 38-42C idle, 57-65C moderate load, most peak usage tops out around 70-72C, stress testing 76C-87C, PBO depending. And I have a somewhat restrictive case for airflow. But if the board and chipset are getting too hot, that wouldn't help. I still think the Corsair RAM is a factor. I'd swap the RAM with something known to work well with the board and CPU before RMA'ing the chip. Another thing to try would be, if your RAM is multiple DIMM, to try running with only one at a time and see if the problem can be isolated to one particular DIMM. But this site is loaded with posts from folks constantly crashing with Corsair RAM and Ryzen power.

Yeah but the ram worked 100% with the 3600 Ryzen 5, so I would have thought that if it run and functions the same on a 5900x as on the website it says they have been tested on nearly every AMD motherboard on the market

I'd expect if it was memory compatibility it would be the older CPU.  I had every generation of Ryzen and the 5900x is the only one that runs 4 chips at stock 3600Mhz.  It by far has the best memory controller unless of course you got one that is defective.

It's hit and miss with these Ryzens. Ryzens are funny about RAM to start with, but what works with one might not work with another. Board compatibility vs RAM vs CPU is always a factor. I'm RMA'ing a board right now that ran my 5900X 4 months with RAM that the board manufacturer hasn't certified, but the RAM manufacturer has. Who's right? The $64 million question...

I think OP meant the 3600 being the Ryzen 5 3600, not that the RAM was being run at 3600. They said their RAM was 3200, not 3600.

[steeno78]

Yeah I just checked and my memory according to most sites, including corsair website and it's compatible. It's actually rated in the top 8 with some sites for that exact CPU lol

The motherboard spec sheet also

Just do it already, seems like the easiest solution.

[-rascal-]

@steeno78

Did you reset the BIOS after swapping the CPU from the Ryzen 3600 to the 5900X on the X570 board?

Which DIMM slots are you using?

Does the system POST and boot up properly if the memory is running at default JEDEC (i.e. XMP disabled)?

[freeagent]

Corsair does not have a good rep with Zen 3.

 

Its pretty terrible actually.

B450, B550, X570.. none of that plays any role in how well a chip will run, zero. Chipset does not determine board quality. Period. Additionally, there are boards with all chipsets that really great and really crappy power delivery, each board needs to be looked at individually. We don't want to perpetuate the myth that somehow just picking a certain chipset guarantees you a quality or performance level, its features only, for the most part. There are some absolutely laughable X570 boards that high end B450 boards would obliterate with a high end chip installed.

There is a lot of confusion and misdirection going on in this thread and you're suffering for it. You don't have a temp problem, you don't have a VRM problem, and B550 on that MSI board is more than capable of fully utilizing a 5900x.

 

You say you installed a the latest non-BETA BIOS. Looking at the support page for that board, that looks to be 7B85v1C. 7B85v1C is AGESA level 1.0.0.6 from June 2020, over two years ago. 

 

To boot with a Ryzen 5000 chip, you need a BIOS with AGESA level 1.1.8.0 or above. BIOS 7B85v1G2 is level 1.2.0.7.

 

The simplest things are being overlooked and some people are going down rabbit holes.. Update your BIOS.

I won't argue, but would like to say that my previous 1700 had a rather popular B450 board that choked at the first sign of component upgrades. So I think this is fairly subjective. VRM cooling is important with most, if not all Zen3 though.

[steeno78]

Ok there seems to be confusion lol. Maybe my bad for not explaining properly. The board I'm working with here is the MSI MAG X570 Tomahawk wifi.

 

With the 3600 Ryzen 5 it works fine. With Ryzen 9 5900x it runs for minutes then hangs on a black screen. The board is running the latest BIOS, which at this moment is 7C84v19 released in 2022

And I still maintain that the Corsair RAM may be a factor. Just search "Ryzen Corsair RAM crash" in the forums and see what you find. You'll see a bit of my explaining older posts to folks with these issues, but there is indeed a pattern that has shown itself of late.

All the suspicion is there.....

 

RMA the processor. 

Whea errors after bios updates even if you do get it running...RMA anyways.
