5800X - Low Cinebench R20 scores

[Guest2]

Do these scores look low?

Cinebench R20
CPU multi 5271
CPU single 491

I have BIOS defaults enabled, XMP on auto and RAM is looking correct.

MSI MEG Unify X570
BIOS is up to date (1 version behind - 7C35vA7)
https://www.msi.com/Motherboard/support/MEG-X570-UNIFY#down-bios

AMD Chipset drivers have been reinstalled. No issues with a Ryzen 5 3600 in the same board.

CPUZ bench looks ok, 651 single, 6611.4 multi

edit, there is only 1x 8 pin power (2x4 pin) to motherboard. It does have the optino of adding another 8 pin power connection but was told this is for LN2 use only

edit 2, ill start by getting the latest bios applied as have noticed this thread

https://forum-en.msi.com/index.php?...igher-than-3200mhz-with-a-ryzen-5800x.349509/

you really want both 8 pin cpu power sockets connected. they are not for LN2 use only.

Are you sure? Someone on these forums specifically said the 2nd connection was not required. There was a youtube video initially stating to use them for PCIe4 full power or something on those line. Then he went back and corrected himself as proved the 2nd 8 pin was not used at all when measuring it was a multimeter.

I have updated to the latest BIOS and scores are looking more normal

6031 / 627

Presume a BIOS issue as small issues are slowly ironed out

the 2 8 pin sockets near the CPU should be used, it spreads the load across both sockets.

Do you know this for a fact? I'm sure there's a youtube vid of someone who goes into the detailed hardware setup of the MEG Unify board, he tested the power usage with a multimeter and one of the 8 pin connectors was not used at all

More than a 60% increase on Timespy CPU score when compared to the 3600...
(7656 scored on a 3600)

Is there some advantage to not plugging it in?
Just 'cos I'd plug it in if I have the power cable available... why not?

That was my initial thought, but then no point and just clutters things up a bit more if it's plugged in

 

[Guest2]

6 minutes in

Then this

 

[Guest2]

well i would say if you have the power cable then plug it in. it will spread the load to the CPU and although you might well be able to get away with 1 plugged in but why not use 2 if you have them. as for MSI why put 2 on the board if you only need 1? makes no sense.

Good point.
I think the video was pointing out its not used for pcie4 (gpu, nvme etc.)

Had a quick tidy up and removed an old molex for audio, a front audio header ive not used for maybe 10 years and connected the cpu2 atx.

Cleaner than before actually even if it was a bit fiddly connecting it with the cpu2 connector with the HSF still in place

Just got my 5800x bundle today and the motherboard I got has a 4 pin and 8 pin socket. So I plugged cables in for both.
First run of Cinebench R20 gave me 5934 / 554 with a boast of 4.5ghz. Replaced my 8700k system completely apart from my
drives and GPU. Think there is an issue with cooling as its getting to 82c in Multi core benchmark. It idles at 38c though. I'm running with the case
standard 120mm fans and the standard AIO 120mm fan. Might just need some tinkering the bundle came pre-assembled so
might repaste the CPU with Grizzly see how that goes. Also got some better 140mm fans too so room for tinkering.
Then as a last resort might need to look into getting a 240mm/280mm AIO.

What motherboard?
Make sure bios is up to date

 

[Guest2]

The one in my sig. BIOS is up to date, there is a beta one but would rather wait for it to be final.



This is the one I am on

I'm on a recent beta bios for my MSI MEG Unify X570. The final one was I was on running Cinebench R20 with low scores and a crash when running XMP stock settings is why I created this thread. Updated and problems went away
I suggest putting both bios versions on a USB stick and upgrade to the latest beta bios. Maybe a spare stick with your current one on so you can flash back directly through motherboard usb flash if thats available

disclaimer - if it breaks, its not my fault

 

[Guest2]

I wouldnt read too much into the bios descriptions.
The MSI one says 'Support AMD SAM(SMART ACCESS MEMORY) function'
It obviously fixed more than that with 5000 series as it doesnt crash or give low Cinebench r20 scores anymore. It should have probably read "Improved stability with Ryzen 5000 series CPU...Support AMD SAM..."
Like every company, they wont admit there are issues (or fixed issues) unless everyone starts highlighting them
Big IT software companies are terrible for this. I know as my job for over 10 years is with one of them

somethings wrong as on average a stock out of box chip shoud hit over 600 points single score and around 6,000 points multi score, though ram speed will make a fairly big diffrence, the sweetspot for 2nd and 3rd gen ryzen's are 3600mhz and with 3rd gen it will be more but newer bios's are needed to push upto 4000mhz to run 1:1.

the voltages at stock of around 1.4v are completly normal and are needed for the cpu to boost upto its high frequences, but a big problem is the heat gernerated, if you dont deal with that the cpu all core speed and single core speed will be signifigantly lower which will drop cpu only test scores down dramatically, you need to keep below 80 degrees at a max temp and ideally below 70 but that's pretty hard tbh most chips are around the 70-80 degree mark under load, i know my 5950x at 4.6ghz with 1.3v manual cpu vcore hits 81 degrees under a custom 360mm loop under heavy cpu load

and a big thing is to close down all unessesary background programs too, anything that takes around 1-5% of the cpu will affect scores too

See post 3

I have updated to the latest BIOS and scores are looking more normal

Thanks for info on temps. Think im idle around 30c and max load is 81.5c in Cinebench R20. I am using a low noise / RPM reduction adapter on the CPU fan. I might try it without

 

[Guest2]

whoops my bad, good to see you have it fixed

No probs

I just tried without the low noise adapter... much noisier and temps exactly the same!

One strange thing I noticed I that I swapped the fans around and doing so i moved the rubber gromet things on the corners of the fans. Even with the low noise adapter there was a strange humming sound. I put the rubber gromets and fans back to how they were and it stopped.
It seem the fan pulling if it has the lower profile rbber gromets so making it closer to the heatsink this causes the humming. Slightly larger grommets and a bit further from the heatsink and it goes away. It must be an airflow thing from push fan > HS > pull fan > exhaust fan
