To fix the issue, you don't need to remove or stop afterburner starting.
Yeah suspect I won't be in market until middle of next year / end of summer to be honest. So can wait and see.
I watched this earlier today.
Further to this; during my brief dalliance with a 7900xtx this week, this issue was not present. So it does seem to be a 3080/Nvidia issue. Perhaps the xtx, having 2 HDMI ports against the 3080s 1, has a beefier controller or something.
The minimum value at which the processor is stable on 5.4Ghz. Every cpu is differend and You need to test your one to find out.
This was always my issue with AMD, bugs glitches and compatability issues requiring odd solutions and tinkering.
MSI Afterburner is third party software and nothing to do with AMD. The rest sounds like a severe case of PEBKAC.
Use Auto LLC, your board should pick the optimal setting depending on if you are running fixed voltage or auto. It changes for both, so if you are overriding and using a lower LLC, that will result in marginally lower clock speeds and performance.My overclocking experience with the 9800 X3D: what a bloody chip! It's good to be back to overclockable silicon after the older X3D models
The chip is extremely fast out of the box. Overclocking via +200 PBO boost worked right away, along -20 Curve optimiser. After a bit of fiddling -25 Curve Optimiser is fully stable with Load Line Calibration set to 3. That gives an all-core under OCCT 'Extreme' of around 5.35 GHz, IRL scenarios of loading all cores (e.g. gaming) give 5.4, and 1-4 cores sees >5.4GHz. Low load temps are 45-50, full load is 70-75 using a 280 AIO.
For anyone testing stability I recommend y-cruncher (option 2, option 14, option 0 to give a component test) as that seems to pick up AMD memory or CPU instability most quickly, which can be followed up with OCCT variable and continuous load.
Interesting, I'm running dynamic voltage, will give auto LLC a go, cheers.Use Auto LLC, your board should pick the optimal setting depending on if you are running fixed voltage or auto.

Prime 95 Large FFT works well for FCLK and memory too. It’s a beastly CPU, performance scales nicely with clock speed if you remove the PBO shackles and go up to 5.7Ghz and beyond. Intel are going to have a hard time beating last gen cache for a while, Never mind this new gen. AMD facing similar on the GPU side too.
Idle 20-25 above ambient, load 45-50 above ambient. This is using an NZXT Z63 280mm AIO.
This is not posible without delid and direct die water cooling
Above ambient not actual temps
By using ECLOCK, (ECLK) if your board supports it. Enter BIOS, enable Async ECLK, so you are only changing CPU frequency and not PCI-e lanes, memory etc.
As stooeh noted, I'm giving temps above ambient, not absolute. Fully idle for me is about 40 degrees absolute, 45-50 absolute in light tasks, about 75 under heavy load and up to about 80 under synthetic testing.
I see, so this is (very similar to) throwing a bit of old-fashion FSB overclocking into the mix and forcing the CPU to run at an (up to 44.5x) multiple of the ECLK?By using ECLOCK, (ECLK) if your board supports it. Enter BIOS, enable Async ECLK, so you are only changing CPU frequency and not PCI-e lanes, memory etc.
Set 104.00 ECLK and test. Throw in a little bit of negative either curve optimiser or shaper too. The amount of ECLK you can run whilst maintaining stability will depend on your sample. See a screenshot below of me running Cyberpunk at over 5.75Ghz with a 107 ECLK.
If you run a high ECLK, like over 105, you may need to add positive curve optimiser/shaper to various parts of the voltage/frequency (V/F) curve. I recommend watching the clip below to get your started down the rabbit hole. ECLK, Curve Optimiser and now Curve Shaper are very powerful tools to manipulate the V/F curve of Zen 5 CPUs.
Here's a 10 hour Prime Large FFT run to test FCLK and Memory stability.
