Low Cinebench r20 Score with 9700K

[ne0tic]

Hello! 

 

Basically I have overclocked my i7 9700K to 5.2 GHz at manual 1.420 voltage. It seems stable but will have to stress-test it a lot more. Though one thing I have noticed is that I only get a multi core score of about 3700 in Cinebench r20... I have seen people getting over 4100 points with their i7 9700K at 5.2 GHz. 

 

Does anyone know what the problem might be? All feedback is appreciated! Thanks.

are you sure you're running 5.2 Ghz?, because cinebench seems to detect 3.6.

Yes but Cinebench always reports the stock clock speed which is 3.6 Ghz. HWMonitor says 5.2 GHz during the full run

Run with monitoring software at the same time so you can see if you are throttling, etc - this is an SS I took last night while trying to hit 4.2ghz run - I agree that Cine should see the OC as well.  EDIT - don't just my score, that's without OCing the ram for CPU stability.  Best run is 3956 and have that SS too

No, Cinebench 15 at least shows stock clocks...

I always run it with HwMonitor and CPU-Z open. I have got no throttling, it stays at 5.2Ghz during the whole run and max temp is 88 degrees Celsius.

From what I can tell you are not running @5.2 from the Screenshot. CINEBENCH 20 has done that to me as well, just make sure it says 5.2 in Windows control panel at minimum. I have a 3156 on an R52600 @4.2 so you should definitely get  better than that at your specs

 

[Tristerin]

I find it odd, was discussing this yesterday, CineR15 and R20 have always shown my OCs.  

 

@OP if you aren't hitting the runs that other people are you need to check task manager, make sure nothing else is running.  Close out any startup programs.  You can also set the affinity in task manager to Real Time for a couple more points (just learned this last night) and can push majority of the screen "off screen" for more points. (just learned that last night, haven't tried either trick though)

Okay, you mean Task Manager? I just went to the gym but will check it with Task Manager when I get home so I’m back with the results within 2 hours!

Tried it again with task manager open to check the core speeds and disablede every startup program. It was running at 5.2 Ghz during the whole run and this time the score was about 100 points higher, 3800. It is still quite far away from the 4100-4200 that I have seen other people get with the 9700K at 5.2 Ghz... 

 

I just did the math and realized that something might be wrong with on of the cores on the CPU... If you look at the picture I included at my first post, the Single-core score is 534 and multi-core score is 3723. If you take 534 x 8 = 4272 which is the score I should be close to considering I have got 8 cores and the single score is 534. 534 * 7 = 3738, is about the same as the score I got. It kinda seems to me like only 7 cores out of my 8 work properly considering that my single-core score multiplied with 7 is my multi-core score... Also if you look at my MP Ratio, it is 6.98 x and shouldn't it be closer to 8 x considering my CPU got 8 cores? With other peoples tests they seem to have a MP Ratio of about 7.62 x, and @jstudrawa have a MP Ratio of 7.68 x. To me it seems like one of my cores is broken, but is that even possible? 

[Dedayog]

Don't use me as an example, as the 8700K is 6 cores but with 12 threads, so my ratio won't be like yours.  Try to find other 9700K runs and see what they get.

 

It's not an exact multiplier.  1 core x 8 for example.  Programs don't use all cores the same. In a perfect world, yes.  But in reality, no.

Oh, didn't think about that. Though what I have found is that most 9700K seems to have a ratio of about 7.55-7.7 x so something is weird with mine...

When you run Cinebench, watch the Task Manager or HWInfo or GPU-Z like I had up to see each cores performance.

Yeah, that is what I'm doing all the time. Every one of the cores operates between 5198 MHz - 5203 MHz.

In Task Manager tho, for example, it has a utilization graph as well.  maybe one core isn't running 100% like the others?

Fof reference my 5ghz 8700k gets just over 4000 points in R20

Gah, now I have to download C20 and see how mine fares

Mine might be lower now.

 

I did it a few months ago, but I I had the most up to date micro codes and stuff at that time.

Micro codes?  I just have mine on the BIOS Profile for 5.0GHz, so it's not optimized all that far I don't think.

Yeah I meant BIOS updates.

 

Here's the last one I did at 3995 at 5ghz and 4065 at 5.1

 

I've got better results and I swear I posted them somewhere but whatever around 4k margin of error

I also think this is weird, but CB has never showed my OC's.  I only OC my intel rig, so maybe there is something to that?  I let ryzen ones run at stock.  But my CB's have always reported the base clock only, never the OC.  The scores always reflect the OC though

They are all running at 100%, though this time I actually got a score of 3890! Though that is still about 300 points lower then what I’ve seen other people get...

When you run CINEBENCH is it installed or are you running it just from the .EXE itself? When I install it, it will recognize what GHz I am running. Right now I ran it just from the .EXE and it is not installed and no matter what I do it still says I am running stock 3.4GHZ, when I know I am running at 4.2GHz @37c idle, lowest idle @20c, MAX Temp @70c running CINEBENCH. AMD RyzenMaster, MSI Command Center, CoreTemp, and Performance Monitor all say 4.2GHz. Odd part, System says, 3.4Ghz. Programming is only as smart as the programmer, damn Humans.

Can just simply be your memory installed performs different then the one others had used. 
OCing my memory and tightening timings, just a lil bit not until perfection, gave me a 150pt plus. 
Btw, CB20 shows my ryzen 2600 OC when testing.
