My speed is at 4.550 ghz during a Cinebench run with pbo enabled. I sent the PC back to the store that built it, and they said they tried putting in a new CPU and putting the CPU on another motherboard with the same issue, so they called it normal. Are they wrong? I also tried the curve optimizer and got 4.6 MHz then. The motherboard is a b650 tomahawk max Temperature 78c

Here is what the store said:

Speed on the processor momentarily peaks at around 5 GHz across all cores upon arrival. All-core and stress tests usually settle around 4.55 GHz. Tested with another processor, and the processor was tested on another motherboard with equivalent results in terms of frequency. Different frequencies on all-core with different bios: the newer beta version gave high clock speeds but a low Cinebenchscore of 15500 points; the older beta bios from last spring peaked at around 17450 with Expo enabled. The current BIOS 1.70 gave 17280 points in the last test and was stable at start-up with us. Longer startup/boot, but nothing beyond what we normally see at 6000 MHz and AMD, tight settings, and memory training are done at every startup. The processor cooler was adjusted to "offset mode" for better cooling. No impact in terms of frequency or points was noticed from this.



If i can get someone from msi that can say that this is not normal i can use that as proof to the store

An X3D CPU will score lower than a none X3D CPU in a Full load Benchmark

Ram speed should haves no Bearing on Cinabench score

Max frequency is only for single-core workloads Multi-core workloads Frequency will be lower.

And yes Cinbench scores will vary from Bios to Bios.
And CPU to CPU even the same type of CPU
Due to Cooling and how good the Silcon is for that CPU as well as Bios tweaks

Configure Bios for faster boot times


Clear CMOS and boot to BIOS
Please note all ways save your setting using F10 other methods may not save correctly.
Set EXPO or A-XMP Press F10 save and boot back to bios
Set Powerdown Mode for RAM to Enable Press F10 Save and boot back to BIOS
When back in BIOS check to see if your settings have saved correctly,
If so Enable Memory Context Restore Press F10 and save
Boot to Windows and check for stability
Make sure No BSOD
Do a Memory stress test
If all these works and settings are correctly working, Boot back to Bios and set Fan curves etc. PBO for CPU and the Like F10 and save.
When Memory is training you need to allow for up to 3 minutes to boot
For the first few boots to bios Memory training may happen allow for that time.
When making changes to Bois or doing a clear Cmos or Bios Update system will run memory training

THis is my R5 7600XT Overclocked to 5400 all core

Your R7 7800X3D shoud score same or a bit better due to its lower over all clock speed

Thank you for that. So you think 4.550 is normal under R23?

Any PBO settings?
Take a screenshot of HWinfo close of the end when Cinebench R23 is running.

I have tried using the motherboard in the PBO settings. I tried the auto-OC in Ryzen Master 4.55, which is the maximum I get during multi-core. What screenshot do you want?

What's your CPU cooler? 17280 points in CB23 Multi would at least start to get into the ballpark for this CPU model.

But also, some variation of each specific CPU is normal. See here:


It just shouldn't be too large, you still want to get roughly what you paid for.

HWinfo. Thats a monitoring tool.
You can run it while you are running cinebench.
And close to the end of the bench mark, like 2 Minutes left, you can take a screenshot of the whole window with all infos.

To check the sensors with HWinfo64 during a Cinebench run, run it and open "Sensors", then expand all sensors by clicking on the little <--> arrows on the bottom, also expand the columns of the sensors a bit so everything can be read. Make it three big columns of sensors (or four, if the screen resolution is high enough). In the end, it should be a screenshot with all the sensors visible at once, like this:

Make sure your power plan in Windows is on "Balanced". Do nothing on the PC for a while (couple minutes), so the "minimum" baselines for the values are established. After that time in idle, then produce full CPU load with Cinebench R23, and after completing a 10 minute run, when the CPU temperatures have stabilized at the highest level, take a screenshot of the sensor window and post the Cinebench score. No need to screenshot it two minutes before the run ends, the maximum values will have all the peak temperatures etc. even after the run ends.

oh i know how to use hwinfo64 Thats what i have been using My max temperature while running Cinebench is 78 °C, and it is steady at 4.550 °C. I get around 17390. My cooler is an Artic Freezer 360. If you still want informational pictures, I will link them tomorrow, but I am not thermally throttling. Do you guys think this CPU is broken?

Could just as well be more of a configuration problem. Maybe the guys at the store were onto something with the BIOS versions. You could basically try any BIOS version from 7D75v16 onwards (where they added a prevention of the X3D CPUs blowing up sometimes).

Your score is about normal for that CPU So Yes it good, you could tweak more in bios with PBO and curve offset as well as CPU Voltage negative offset will improve it more

i do have a curve optimizer that is stable. i will try doing a cpu volt negative, see the scores and report back

I would try older BIOS versions first. You are not terribly far off from the norm with your score. In several reviews like here, it hit slightly above 18000 points in CB23 Multi. So you're around 4% off. Then we got some like here where you'd be bang on the money. Then we even got one here where you're performing better!

And of course, most of those reviews were done on the launch BIOS versions. The BIOS versions used for the reviews, that just added support for a new CPU, are usually the best-performing versions. Later they have to implement fixes and focus the optimizations more on the stability and reliability, so it will tend to perform a bit worse in later versions, but it will also tend to run with less problems.

In trying some older BIOS versions (any from 7D75v16 onwards), you are making sure it's actually the CPU that doesn't want to clock higher, rather than the BIOS messing with it. Because the BIOS has more or less full control on how the CPU behaves.
