    Hi All,

    New system is great and stable (unlike the Ryzen 5900x/Dark Hero build I had in the past!)

    Use the system primarily for gaming anyway! Anyway I have a custom EK loop with an EK360 and 240 radiators with 3 and 2 14mm fans.

    My system copes with the added power consumption of using ABT, all core boost to 5.1GHz single core boost to 5.3GHZ lighter workloads. When gaming average temps are in the low 70's, with peaks in 80s...

    Turn ABT off and it now settles in the high 50s with peaks in mid 60s.

    I know that ABT will not void any warranty as overclocking does, any 11th Gen owners offer suggestions? I don't think the extra heat and power consumption appears to be worth it, as framerates at 1440p don't seem to change at all. Perhaps different in synthetic benchmarks?

    Overclocking voids warranty? Lol

    but ditto on the system stability, that's the reason I want to switch my 5950x to a 12900k

    I know what you mean mate, been overclocking since my i7 920 days! I think it has more to do with ABT a new feature with 11th gen, that will allow it to boost and apply power and voltage limits automatically meaning it is stable, can get toasty though. On Ryzen I found the tech impressive but almost like I was beta testing hardware for AMD! Just don't think they have nailed it yet, Intel platforms for me anyway are way better to work with...

    I feel the same, as well as NVIDIA for GPU. I feel that GPU wise the stability can be hit or miss sometimes with AMD.

    Out of interest, without the ABT what boost clocks can you manage?

    Settles at 4.8GHz all cores.... Massively cooler though, with ABT on and run Real Bench temps can nudge mid 90s, system draw is 800W! Still stable for 8 hours though! Gotta love Intel...

    From all core of 5.1 to single core boost of 5.3 is not much of a boost. Whats voltage at 5.1 and at 5.3?

    800Watts, wow, that'll keep you warm in winter!
    What is your r23 score for multi with that 5.1 all core btw?

    What? The base clock is 3.5GHz that's a 52% boost by my calculation...

    800 Watts system draw? 0.0 that's insane.

    Ahh i thought the all core clock of 5.1 was the base clock.

    That just a cpu test or gpus running too?

    All core boost is 4.8Ghz on the 11900K.

    Well we know the 3090 is also inefficient at about 400 Watts continuous power draw but taking out looses in the PSU and the rest of the system that is still about 300 Watts for the CPU, an 8 core CPU at best equivalent to a 5800X, its nuts.

    Full load GPU and CPU my system draws about 350 to 400 Watts

    I would turn it off and stick with a much cooler, lower voltage all core overclock. Ive settled at 4.9 on my 10900k, but could have pushed it higher. I prefer a cooler cpu. I won’t notice the difference in gaming between 4.9 and say 5.1 anyway. It’s been rock solid in everything.

    4.8Ghz if cooling and motherboard allows IIRC. Performance is opportunistic.

    But, yeah just get 5900X and RX6900XT. Bonkers performance for much less power use. 800 watts is a lot to dissipate into a room.

    That's not a big ask on higher end boards and good AIO's.

    Its actually easier to cool an 11900K despite its high power draw because it's a large monolithic die about an inch squared, it has lost of surface area to transfer the heat where as the Zen 3 CPU chiplets are no bigger than your little fingernail.
    I'm hitting 80c in Cinebench but my RAD, even the tubes out of the pump are room temperature.

    @Jonnygrunge What PSU do you have? If temps are not exceeding 90c i wouldn't worry about the CPU, i think they are rated to 100c or 105c TJMax.

    I would worry more about the GPU because its been known to blow even pretty decent PSU's on the count that all GPU's have momentary power spikes and the 3090 can do this pretty spectacularly, good PSU's are designed with that in mind but if you already have a continuous load on it near its rated output a large spike from that 3090 could be what makes it go *pop*

    To sum up with ABT on all cores boost to 5.1GHz in my system with Custom dual rad EK loop. With ABT off all cores boost to 4.8GHz. I quickly benched a game (fairly demanding at 1440p) Ghost Recon - Breakpoint. I ran the in-game benchmark, with both ABT on and off. Interesting results, and temps were 18-20oC cooler for CPU with ABT off! Full system power draw was around 520W.

    ABT on:
