Just bought my Ryzen 7 5800X3D and it doesn't boost high enough all core, only 4150 mhz, what is the solution?

[PeterPaul]

I have a 750W Cooler Master 80+ Gold PSU, an RTX 3080 12GB, the CPU is in my 3 years old MSI Tomahawk Max B450. My cooler is a Fractal Design S24 240mm AiO. I replaced a Ryzen 5 5600x, I have the latest BIOS installed. In Hardware Unboxed review, the CPU maintained a 4350 mhz all core clock after 30 minutes of Cinebench R23 stress testing. In my B450 Tomahawk Max was a Ryzen 9 3900x and it could easily handle it. The CPU is 71-72 Celsius during stressing with Cinebench R23, what doesn't let the CPU go higher in clock, in the Hardware Unboxed review the CPU reaches 80 degrees. Any guess? Thank you for advance!

Did they have PBO enabled?

And have you reset your BIOS since installing a new chip - until you remove CMOS and reset BIOS configs its trying to run the old chip.

(edit, no matter what you need to reset BIOS or you will have random wierd issues)

No, I didn't, I just put the new chip into the PC. Didn't even disabled PBO. I'll try! Thank you!

When you insert a new cpu the bios is automatically reset is it not?

 

Thermals should be the only thing keeping you from the 4450 redline. Each core and thread is capable of reaching 4550, just won’t be at the same time.

Resetted the CMOS, though still every core is 4150 mhz or less now 4125 mhz. And the termals around 71 degrees still.

How is your case airflow?

I have a Fractal Design Meshify 2 Compact, 2x140 mm intake and a 120mm outtake, my AiO also an outtake on the top (my videocard was too long to insert to the front).
I would add that I installed the latest BIOS for the motherboard before I installed it. 7C02v3F (AGESA ComboAm4v2PI 1.2.0.7.)

Can you check hotspot temperature? Maybe the AIO has an improper mount or plastic fatigue or your IHS on your 5800X3D is particularly warped.

How can you mesure the CPU's hotspot temp?

HWinfo

I didn't know where to look for, so here is a picture. I made a screenshot after 10 minutes running Cinebench R23.

I know, but something holds back my CPU to boost where other's CPU boost. I don't want to overclock it, just get the 4350 mhz all core boost clock that my friend got out of box, with worse cooler than mine and I installed a lots of AiO's in my life, but this CPU has something off.

Out of curiosity, if you go a little bit lower on the HWinfo screen you posted earlier there are some performance cap reasons. Any of them triggered?

Do you think it is a problem that these don't reach 100%?

What is the motherboard reporting for power, temps and limits?

I don't know, I was hoping that you will tell me.

I can't see your computer nor the Hwinfo screen you have open on it. Hwinfo has a section for the motherboard.

Sorry, English is my second language. I started a new stress test and after 10 minutes I will make a whole new screenshot, now I understand what you want. It could be shock you but I'm not that stupid, just my English isn't the best.

Here is the motherboard section after 10 minutes of Cinebench R23.

@JurrunioAny thoughts on the B450 Tomahawk Max and a 5800x3d? Seems like it's not getting full power. Low clock speed, low power draw compared to other units. Is the board VRMs enough? None of the board temps are high though?

 Edit: Op is on a 240mm AIO. Guru 3d used a 240mm for that test.

Power Reporting Deviation (Accuracy) is a measure of board's CPU current reading to AGESA (the running logic of the CPU) relative to the CPU's actual current reading. 100% means it's on spot, less than 100% means its under reporting and over 100% (in your case) is over reporting power. For example when the CPU throttles because it's already doing 142W PPT, it's actually using less than 130W due to this 112% over reporting.

 

I'm not sure if this over reporting makes the CPU power throttle eariler than it should since you arent hitting PPT TDC nor EDC limits. You can try raise them by say 10% and see if the performance improve.

It worth a try. Thank you for your time! I didn't want to buy a new Motherboard, because I used a short time a Ryzen 9 3900x in it with PBO enabled and it worked fine, so I thought the Ryzen 7 5800X3D should not have any problem.
