PC Processors

[introibo]

Hi y'all,

I've been benchmarking my 5950x stock (no PBO or overclocking - just straight out of the box).

I got a CineBench score around 24,500 when 5950x users are getting around 29,000.

I just ran CineBench R23 again and scored 23,892 - max temp during test was 64* C.

My CPU has thermal room to perform better - 64* is pretty cool when it has room to get to max at 90* C.

Temps are great - usually 65* C to 70* C under full load.

What should I be achieving at stock? Is this reasonable performance OR do I need to enable PBO?

Something is causing my CPU to underperform as I figured I would get at least advertised performance straight out of the box.

Specs: 5950x + 3600 MHz CL16 DDR-4 + ASUS Strix 3090 OC

Thank you for your time!

Certain you have an actual 5950X and not 3950X which typically gets that 24000 points? Did you check the markings on CPU IHS? What does CPU-Z say? All cores are working in task manager? What kind of clockspeeds do you get?

PSU wattage/quality considering that 3090?

Reset BIOS and enable XMP or DOCP, which ever you have

You did a clean Windows installation when you got this motherboard/CPU and didn't just use old installation to see if it works?

Hi MadZyren, thanks for the response! I'm going to share some more details with you regarding my system:

SPECS - 5950x + ASUS Strix 3090 + Dark Hero VIII X570 Motherboard + 32GB GSKILL Ram 4000MHz CL 19 (tuned to 3600MHz CL 16)

I built this system from scratch and installed a clean version of Windows 10. BIOS was reset last week and I re-enabled my ram timings (DOCP crashes for me because I am using 32 GB of unsupported ram - 4000MHZ with my motherboard QVL. I've set the clocks to 3600 MHZ CL16 which performs faster than my 4000MHZ CL 19)

PSU - EVGA 850 G3 - see specs here

Certified 5950x CPU

Current Ram Timings 3600MHz CL 16 (I'm still tuning the middle ones that are 25s)

A quick Benchmark reveals all cores working

While running Cinebench R23 (all cores boosting equally) - Temp is 61* C and holding

Also - here is the total load on my PSU with all my PC Specs

In Cinebench R23 - all cores boosting at 3.6 GHz while having low temp of 61* C

I appreciate any insights you might have with this. System is very stable, no hints of any problems.

I would put in BIOS PBO on "AUTO" that way when the processor needs more power it will boost up to it maximum speed which should improve your scores.

PBO is just AMD way of safely overclocking your Processor. Also see if you have Core Boost or something similar that works with PBO.

NOTE: Your score can be affected  by your RAM speed and other factors.

Bizarre.

A couple of things come to mind. Check CineR23 settings that you have not limited core count to say twelve and forgotten it. Second would be some performance destroying memory subtiming. I would try using unchanged XMP settings, but let's say at 3200MT/s and make sure it's 1:1.

But now after checking some benchmarks, it would appear that 24000 point is not that uncommon for 5950X. 3950X simply are surprisingly close in this benchmark. Maybe those high scores were overclock results from delidded or LN2 cooled CPU's. See for instance Hardware unboxed 27.9.2022 in Youtube. I think your CPU is actually fine. I saw some result at 28000+ and wrongfully assumed it is normal for that CPU

[introibo]

Wow, that's surprising findings from the video you mentioned here, and I am even more relieved that my CPU is doing just fine.

It makes me wonder if the Passmark results of 46,000 for the 5950x are due to the PBO being enabled and overclocking? That would make sense.

Stock 5950x is benching 38,000 in the CPU test.

[MADZyren]

Maybe you should run a group of tests and see how your CPU performs againsta other 5950X's to see the big picture.

I can tell you that in the period just before my first 5950x bit the dust my performance just started decreasing and at the end a 5900x felt fast in comparison.  Once I got the replacement 5950x in I installed it and we were back to normal performance.

I caught it running the time spy benchmark and noticed that my scores were steadily dropping until it was replaced.  Right now I'm trying to decide just how long I'm going to keep it before jumping to a 13900k.

I'll just sell it and the 5900x and apply it against my upgrade costs.

[MADZyren]

What you describe is not a CPU issue. Either there is something seriously wrong with your motherboard, PSU or settings. 

Reset BIOS, enable XMP/DOCP.

When something similar happened to me, I was (knowingly) overclocking/overvolting a CPU way too much to push it to limits. 

[hrpuffnstuff]

It absolutely was a CPU issue and AMD rma'd it when the bad cpu light turned red.

which AMD store did you go to to have it tested and WHICH store that wasnt the AMD website or official AMD store did you order it from?

did you enable and configure TPM 2.0 and PCIexpress and secureboot and resizeable bar and above 4G decoding and other things first? did you check all your boards memory stuff is auto or enabled too?

did you set your CPU clocks and mhz and base frequency to auto or 0 first? its often set to something screwy by default in bios u maybe need update bios to most recent or the oldest.. its confusing.

try set your RAM to be lowest latency lowest mhz and no XMP but apply the voltages XMP wants.

disable gear down and command rate 1T  then set manual super quick barely boots secondary and CAS latency ram timings and refresh cycles as seen in typhoon burner free edition for your sticks.

then uhh after a reboot set it all back to auto. you may need to clear cmos a bunch of times to get a working low boot that may appear very slow. but you just gotta let the hardware know what it can do so when you set it to auto it will kinda average it out like a **bleep**ty nvidia dlss upscaling pretend 4k for your beyond 12k hardware.

next you will wanna be hardware DEP for all files not just OS, core isolation and memory integrity on and enable all exploit protection. then you want to delete all restore points and disable system protection after a backup. maybe disable drive indexing and set to no page file if no older spinning disks drives.

uhh run cleanmgr.exe /veryverylowdisk and open up windows defrag tool and turn its scheduling off and manually do it every so often.

the uhh disable system protection and delete restore points and no page file probably gotta do every reboot and the hardware DEP.. looks like its on but toggle it again anyways. try not to use ryzen master uninstall that stuff from task scheduler as its hardware speed steps and power manages and all the custom ryzen master stuff is super limiting and crippling it. your windows BIOS management is bending you over. set bios to false or something maybe disable it. type in best CAS TRC and other memory typings into the OS not sure if they work work.. but it appears to help.
