How's everyone getting on with overclocking?

Don't seem to be able to go above 5425mhz all core. Running Thermaltake Phantom Spirit and PBO +200 CO-30 (mine is actually stable at -40 but can't see any difference in performance).

Temps are good 48 degrees idle, 57 average when gaming (spiking up to a max of 68) and hitting 90 when benchmarking, all using a low rpm silent fan curve with a Thermalright Phantom Spirit air cooler and some very old Artic MX-2 paste.

Set my IF to 2200 yesterday which improved all benchmark scores and games' fps by 5%, but it's crashing today on desktop/low usage. I suspect I need to change the SOC voltage but I don't really like messing around with voltages and my Asus voltage bios settings are confusing. The recommended is 1.15 volt at 2200, but the Asus stock auto settings are running at 1.264, so I dialled IF back to 2067 which is stable.

I got mine yesterday, and on initial inspections, I completely loss the silicon lottery lol, like my chip can't even go above 5.25ghz with standard pbo and CO, that's how bad the voltage frequency curve is. I'm currently messing with eclk and curve shaper to see if I can get some higher single core boosts as the only saving grace is my first core is really good lol

5425 is the cap unless you use manual overclock or BCLK/ECLK.

Yup, I've noticed it, but even getting to 5.5ghz all cores is basically impossible, in scatterbench overclock even he couldn't get it with a golden chip. A good overclock is a 5.4ghz all cores and a 5.6+ ghz single core/boost with curve shaper and eclk

Which core number is the main core for boost speed?
About your overclock : When I have buy my 98003D was not possible to run the cpu more that 5450 with my first motherboard ASRock X870 Pro RS WiFi. This board is the most cheep one and was only X870 avaible one mount ago when I buy the CPU. Bu 1 week ago I replace the board with ASRock x870 Riptade WiFi and now my CPU can work stable on 5550Mhz . The reason for the better stable overclock is the better capacitors on ASRock x870 Riptade WiFi , 20K 1000mF for the VRMs. I also saw on the net that overclocking this processor is of no use in games. So, there's no point in frying too much.That's why AMD put a factory boost clock of only 200MHz in the BIOS. Also that why there have alsmost no fps test with stock and clock one. I have plan to delid it and put termalgrizzly direct die water block and run it on max top speed but after this video i change my mind :

Yeah I got an X670E Crosshair Hero motherboard, so in theory that should be fine, the only issue is I can't get higher than 5.2ghz as my voltage curve is a lot worse than other samples, pbo has to give around 1.25v for it to be stable at 5.2ghz and anything higher it's not worth imo
 
I oveclock my 9800X3D manual from adm overclock menu in the bios without any curve or PBO. I put there the speed(5570 , to have 5550,+20 extra on the speed which U want to have, becase buss speed is 99.80Mhz in reality) and the voltage (1.260V) and for "Precision Boost Overdrive" is "Advance", PBO limit is "Motherboard". That is for the overclock of the CPU,nothing else. The ram speed and timings I overclocked from OC Tweaker menu. The strange is that If I overclok also the CPU from OC Tweaker menu ist not stable. U can try to play with buss speed,but my presonal experiance show that if I touch it everything go imidiately wery unstable haha :D

Try with this way. Normaly all 9800X3D can work stable on 5450Mhz,that why amd put extra PBO overcklok of +200Mhz

Also do stability test with Aida64, its not so haevy test (cinebench is super heavy) , because in the real scenario of use there have no game which can push the cpu like cinebench. Ofcours if it stable in cinebench will be better,but also will be perfect for daly use and games if can hadle Aida64.

There's a couple on OCN with chips that can do 5500+ but it does seem quite rare. I am barely able to finish a CB23 run at 5450 @ manual 1.2v so stability somewhere even less than that. I can get about 5500 using eclk and some +CO. I was trying 5600 using +200 and eclk yesterday and it was running games and CB23 okay but hard crashing on desktop :p
 
I've just upgraded 7800x3d to a 9800x3d and the PC reboots either as soon as windows loads or after a very short time. Temps seem OK in coretemp & bios.

I updated the bios on my Asus B650e-e to the latest non beta version 3067 beforehand and cleared CMOS.

Ive put the 7800x3d back in and it's fine.
Edit.

I've downgraded the bios to 3025 and same issue.

Any ideas?

First check your ram in memorry QVL list of your board for compatibility with 9800X3D
Instal back the latest bios and reset it to defalt
After :
1 Try to start the pc with 9800x3d and one of the ram stick then other one
2 Try different ram slot
3 Try also to disable fast boot option from the bios
4 Try diffrent ram if you have
5 Try to run windows in safe mode with 9800x3d,maybe the windows do not like the new CPU some how (example: the chipset drivers on it is a for 7800x3d) and maybe need to be reinstal.

For me your sitiation sound like a ram issue

Ive tried another 9800X3D and that works, seems ive got a faulty one. :(

THe one that works is showing incorrect clock in core temp. Its peaking at all core 6476 Mhz and idle is 573 Mhz.

Ive reflashed bios 3067 and same issue.

Look at the LED error Q-code on your mobo
 
You know a new bios came out a couple of days ago Version 3201 (you say you tried 3025 and 3067)? They also need last week's AMD chipset drivers 7.01.08.129.
6.8ghz is not possible so it's being reported wrong. Have you looked at your internal clock speeds (most likely BCLK) and IF? Maybe you accidently punched a number in wrong or something.

Where are you getting the 6.8ghz figure from - have you checked Task Manager, HWINFO and CPU-Z and they are all reporting the same?

The bios has defaults loaded & reset CMOS before.

I didn't want to try the new beta 3201 bios as I'm already having enough problems. I thought older tried and tested versions would be better for now.

I have custom water cooling and my 9800x3d gets to 80'c on load sometimes. Have I made a poor mount? Also using new thermal take Helios solid thermal interface material.

what are you using to test it with. Now I am no expert here so take this with a pinch of salt. Is it stock? It sounds on the slightly higer side of things if you are using custom water cooling but not to the point where it is bad. Have you applied the +200 core speed over ride as this will add some heat to things. What is your Loadline calibration set to? Have you tried using a negative offset?

I just did a quick and dirty run and my max temp under load under c23 was 74.6c call it 75c. I am using a cheapy AIO and have a fan curve where it doesn;t spin up to 75c. So I never heard the fans spin up.
