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 :
