Question New prebuilt PC Question

[GenericJim]

My friend is new to pcs, and with Black Friday he got a good deal on a prebuilt pc, I helped him set it up and everything looked great until we tried to benchmark, the CPU seems to be falling a bit short when benchmarking.
The cpu is actually running at somewhat of an eco mode it appears, with it averaging 3.5 mhz and only hitting about 45 degrees during the time spy cpu test on 3d mark.
Attached is a link to the test results.

I know 3d mark isn’t the greatest benchmark. He was curious as I showed him my pcs benchmarks and he was wanting to see what his looked like in comparison. But also it’s the one I owned and easiest for me to explain with the results with all the graphs and numbers it gives, plus using the compare stuff to show him.

Fixes attempted
Checked xmp- is enabled
Virtualization-off
Power plan-max performance

Got a link to the prebuilt?

Did the prebuilt come with the OS or did you install the OS? If the latter, where did you source the installer for the OS?

I see your ram running at 5,186 MHz, if the ram that came with your prebuilt is rated to only go as far as 5200MHz, then you've left performance on the table. You should've looked at DDR5-6000MHz or slightly higher dual channel tight latency ram kit.

What BIOS version are you on for your motherboard?

UIs that your or his benchmark result ?

That’s his benchmark.

I’m not sure of the bios motherboard version, I but yea the ram is only 5200 with xmp enabled, but I would think that wouldnt kill his cpu mhz to only 3.5

That’s his benchmark.

It's difficult to compare scores unless benchmarks are done on exactly same PC and under same conditions. Also 3,416MHz is average frequency but it did peak to 5,387MHz. Average because CPU is not used same way and to same extent thru all tests. I'd say, 83% is quite better than most and you don't know if others are not overclocked etc. To see what frequencies a CPU is capable off, it needs prolonged full load in a benchmark like for instance CineBench 23 or 2024 or OCCT while monitoring temperatures and power.

Yes I was thinking that too, I would’ve figured it would’ve at least held boost clocks through the cpu test being only at 47 degrees I think. Which, don’t get me wrong, is good because it’s always cool and not just dumping heat like my 7950x does.

14700f is not cooler CPU, with it's max temperature up to 100c while your 7950x Tjmax is 95c. So if it's maximum peak temperature is only 47c. under full load, makes me think it's not set adjusted for full performance. on the other hand, 3Dmark simulates game conditions which with top tier CPUs is rarely full load.
As said before, only way to find it's full potential is to use program that can push it all the way for at least few minutes while monitoring temps, frequencies and power.
