Ryzen 5 5600X instability during high sustained CPU load with core performance boost on

Jump to solution

Hi, I recently upgraded my CPU+motherboard to a Ryzen 5 5600X and a Gigabyte B550M AORUS PRO over the weekend. Since then my computer has been shutting off/crashing (power straight up cut, not BSoD, can turn PC back on immediately after) during high sustained CPU loads. (high fps games, cinebench, etc)

I have been troubleshooting since then and in the process, I have ruled out a couple of potential issues. I initially suspected it was overheating, so I bought a new CPU cooler and now my temperatures under max load is 75 degrees Celsius. Then I did a fresh reinstall of Windows. Finally, I tried updating my BIOS to F11g and still no dice. 

Eventually, I found out that turning off core performance boost in the BIOS has allowed my system to be stable at high sustained CPU loads. However, this disables the turbo frequency and therefore the all cores are permanently stuck at 3.7 GHz or below, never to go higher. 

I am unsure what to do now and help regarding this issue would be greatly appreciated.

System specs:

OS: Windows 10 version 20H2

CPU: Ryzen 5 5600X

CPU cooler: Dark Rock 4

Motherboard: GIGABYTE B550M AORUS PRO

RAM: Crucial Ballistix 2x8 3200MHz CL16

GPU: GIGABYTE RTX 2070 SUPER WINDFORCE OC 3X

PSU: Corsair CX-M 650w (had this in my previous build and was working fine, don't think it's the PSU)

BIOS version: F11g

I looked into it more and found someone with the same CPU+mobo combo that had a similar issue but with XMP instead. Apparently, having both CPB and XMP on will cause instability, and either one of them off will allow the system to be stable. I feel pretty dumb for not checking that first. So now it seems more of a motherboard issue since I've had XMP enabled with my previous mobo+cpu without issues. Hopefully there's a BIOS update that allows it to be stable at max speed. Time to cancel the order of my 5800x...

I have the similar problem except I even can't POST with 4x8 gb ram.

The mobo b550m Aorus pro. Bios - 3 latest one by one (f11g currently).

But I can POST and boot only with 2 or 3 sticks and never with all 4. With all 4 it spinning coolers like crazy and no result. Or post but not see in bios 2 modules from 4.

Very strange. That is not what you expect buying new processor.

I already read almost all the internet and found that there are many people have this trouble with new 5600x.

The same problem with gigabyte, asus and msi motherboards and different sets of memory.

It looks like something in new CPU memory controller is unfinished and works bad.

What have I do? Return the CPU back?

Wow that sucks. As the other poster mentioned he is having problems too. Looks like this time around is having some real growing pains. Zen 1 and 2 had theirs too but got sorted by about 6 months but that is a long time to wait for a fix. Not saying it will be that long. Who know. 

Just report it to your motherboard maker and to AMD here too: https://www.amd.com/en/support/contact-email-form

If it is more than you care to deal with you can return it and try again in future months when hopefully they get it sorted. 

 

I really am sorry to hear you are having this issue as I really hoped AMD would do a bit better. 

Talk to AMD maybe there are just some bad CPUs and another if RMA'd would not have the same issue. 

Good Luck and sorry again for your trouble.

Are you using Windows Balanced power plan, and also do not have Ryzenmaster installed ?

I had Ryzen Master installed. Power plan was default (balanced pretty sure) for the most part. I did change to the high performance power plan halfway through testing to see if changing that would help anything though (spoiler: it didn't)

I ended up ordering a 5800X and will return this as soon as it arrives. I'm pretty glad the store I bought it from has a good return policy. Also a little off-topic rant: It's a huge inconvenience to RMA with AMD for me cause you have to go without it for a week to months, especially if I need the computer for school/work but I guess in most cases people who are using RMA straight up don't have a CPU that at least works to some extent.

Yes RMA sucks. One of the reasons I buy my stuff at Micro Center. I buy a lot of their house brand stuff as they replace it on the spot if you have an issue. There extended warranty stuff is pretty cheap too. Then if you have a problem you just walk in and the replace it without the RMA headaches. This is something brick and mortar stores are still very good for.

otcompa, I recommend more power - perhaps 800 Watts.  Enjoy, John.

My system definitely isn't drawing anywhere close to 800 watts.

I doubt that you are drawing more than 800 too but, knowing that you are using an older power supply and now looking at the specs for your actual graphics card it is 650 watts and being an  OC edition that pulls more power its peak amps can be higher than reference. If you were by chance right on the edge with your old processor or as you find doesn't happen with the new processor with PBO the possibility of not enough power does make a whole lot of sense. It really is a good possibility and can be checked without going out to buy a new one.

Download OCCT free diagnostic software from OCBASE dot COM. You can test the system, it can put the GPU and CPU under full load and show what power draw is and if it is falling short under load. You can run another app like HWINFO at the same time if you like to watch the voltage in real time as OCCT does the test too. 

Worth looking into. It is quick and free to see if it is an issue. 

Worth mentioning and I re-use plenty of power supplies in new builds too, but they do begin to degrade from day one. Just like a shock absorber on your car, little by little they get worse until you have to replace them. 

Your power supply when new is at the minimum for your system hardware. It is certainly possible if it has even degrade a little it can't hit the peak amps your system requires. 

It really is usually much better to go about 100 watts or more over what you need when buying a PSU. 

This all being said it most certainly may have nothing to do with the PSU either but running that test will help figure it out. 

 

Good Luck!

I was kinda vague about it but this PSU is only a month old. Not new enough to not know any problems with it by now, not old enough for it to degrade unless I'm super unlucky lol. I've been slowly upgrading my PC over the course of the last 1-2 months. It's worth noting that my system is still unstable (with CPB on) even with 0 load on the GPU but I'll definitely check it out still. Thanks!
