AMD Ryzen 7 9800X3D

[opethdisciple]

Ok my run finished score in cinebench24 is 1334 multi.

 

[opethdisciple]

I'm trying the settings in this guide.

Ok so even following this guide my chip at 100% multi core in cinebench24 is at 5.20-5.22GHz

 

[Richdog]

Out of the box mine boosts to 4.94GHz. After enabling PBO +200 it hits 5.2GHz.

This was the same story with my 5800x3d. Only using -15 co did it hit it's max clocks.

The spec of a 9800x3D is to boost to 5.2ghz so iIf it's only boosting to 4.94ghz then you have a problem that you need to figure out and its likely motherboard or cooling related.

 

[Nitefly]

Ok I just enabled pbo +200mhz and -20.

All core boost under 100% load is 5.2GHz.

How are people going higher than this?

It should be going to 5.4ghz with a +200, since 5.2 is default.

 

[opethdisciple]

Well what can I say.

Mine is topping out at 5.2GHz with these settings (image from igors lab)

I've had exceptionally bad luck with the 9800X3D.

Two have now died on me after approximately one week's usage. (Identical configuration ran the 7600X fine for 6-7 weeks while awaiting the RMA replacement)

Whether it's a fault with ASRock motherboards specific to the 9800X3D or very bad quality control at AMD remains to be seen.

I see people literally dissecting their processors to inch out a percentage point more performance without a hiccup and here I am with two dead processors after being mortified at even enabling EXPO.

Which ASRock board do you have ? I know around the launch some sockets were slightly warped so certain pins didn't make contact and it ended up with some 9800X3D's having issues.

We are not asking you to say anything, we are telling you that you have a problem that you can of course either choose to troubleshoot or leave as is.

 

[opethdisciple]

So far... So good, no reboot

Is this setting likely to hinder performance somewhat I assume?

I'm currently running a stress test on cpu-z and it's boosting all cores to 4.9ghz with a max temp of 79 degrees.

This guys was boosting to 4.9GHz out of the box too.

 

[opethdisciple]

Anyway I've ran abut 20 mins of cinbench24 thus far at it seems stable.

Maybe I am temps or something else constrained as it only boosts to 5.2GHz.

Google and ye shall find.

Does it make any difference if I am watching the speed in windows task manager as opposed to hwinfo etc...?

 

[Nitefly]

Potentially. Why don’t you just use HW info and see how the clocks are boosting with that…?

Always a good idea to double check with more than one tool.

Maybe you should be asking yourself why you would want to use the task manager when you have HWinfo which a tool specifically designed to provide reliable system monitoring with history?

 

[opethdisciple]

Ok... I installed hwinfo.

It looks like it is thermal throttling.

It is hitting the 90c mark.

CPU CCD1 (Tdie) 86c - 91c

Clocks are still at 5.2GHz

Still on my 4th run of cinebench24 and its stable.

Maybe I just lost the silicone lottery.

With PBO enable etc....

5.2GHz multi core 100% load

5.4GHz single core 100% load

Change your cooler with better one,like Artic Freezer Liquid 360/420. 9800X3D have max temp limit to 85C ,after 85C speed go down to reduse themperature.Example my 9800X3D on 5.5Ghz @ 1.260V is around 78-82C in cinebench with Artic Freezer Liquid 360 and MX-4 paste.Your one hit 91C stock with negative PBO which mean is undervolted,this is not normal. Also on 91C your PC shoud restart to protect the cpu. Did U instal the latest bios for this cpu on the motherboard?

 

[opethdisciple]

I think it's working correctly.

Under 100% load in cinebench24 multi core 5.2GHz.

Under 100% load in cinebench24 single core 5.4GHz.

I imagine during gaming it will be hitting 5.4GHz because I can see just after windows has booted just sitting at the desktop for a bit I can see multiple cores boosting to 5.4GHz.

I will monitor later tonight what happens with a game running.

ASRock X870 Pro RS WiFi

The RMA was handled by AMD and took 7 weeks so I'm hoping the replacement wasn't another from the earliest batch.

Sent off the RMA request for the second one and they're requesting the usual dxdiag/msinfo data. 7600X worked fine over the 7 weeks it took them to RMA the first and upon putting in a new 7800X3D yesterday it worked immediately. Very, very strange that two 9800X3Ds died after roughly one week of usage.

Mine arrived today, can't wait to fire it up later on.
Been building pc's for 25+ years and never had the the best cpu at any time, I'm hoping it will last a few years.

Just noticed it has gone up £20 today.
