Morning!
 
I'm needing some guidance with Vcore settings and OC this 9900KF. If I run Clocks on auto and Vcore on Auto the temps get way too high for my comfort zone. Games like BFV that run at a high CPU utilization will heat this chip up in the 80c's real quick.
 
What is a good Vcore and offset for running the clocks on Auto so they can manage the core speeds itself with the Intel Turbomax turned on?
 
Thanks!

    How are you cooling that CPU ?
     
    Intel --> 130W cooler as the entry-level solution
     
    You should be looking @ a AIO 360 or custom loop
     
    Check some OC guides for the 9900K as a good starting point
     
    Auto setting do allow for high voltages

    I'm running on a custom loop.
    Cooling setup is optimal.
     
    I'm trying out a Vcore setting of 1.4 now with a 50mv offset.
    under full load hitting around 67-70c with all cores hitting around 4.7ghz

    Thank you Sir!
     
    I found 2 sweet spots I'm good with.
     
    5.0ghz  Ring ratio 5ghz and AVX 0
    Vcore 1.3 offset 50
    At 100% Aida64 stess test runs at around 78c
     
    running in game at around 60-80% load ex BFV its a bit on the warm side 65-70c
    Other games with lower CPU loads around 20-40% runs winthin reason of 58-62c
     
    4.8ghz ring ratio 4.8 and AVX 0
    Vcore 1.2 offset 50
     
    running in game at around 60-80% load ex BFV 60-65c
    Other games with lower CPU loads around 20-40% a lot cooler 52-60c
     
     
    I think 4.8ghz is going to be the regular for gaming and everyday use.
     
     
    I really like this Chip!

    When you say "100% with AIDA64", are you stressing everything?
     
    Also, what does AIDA64 show as the actual CPU Core voltage during the test?
     
    Thanks

    Aida 64 streess testing CPU FSB and memory. all cores 100% utilization on all cores. 
     
    Vcore shows around 1.4  @ 5ghz during stress test.

    I am impressed. Using your settings, I overheat almost immediately.
     
    What is your loop?

    EK blocks, D5 pump and EK reservoir.
     
    280mm Rad.
     
    nothing special. 
     
    Also I did this test during the day while it was warm in the room. About 75F

    Beats my D5, triple 140, and Heatkiller... also mid 70°s.
     
    I wonder if having iGPU on my 9900K, even though it is disabled in BIOS, really adds that much more heat.
     
    I noticed with AIDA64, enabling the FPU is what really causes the overheating, everything else only gets me into the mid 60°s.
     
    I can run 10 passes of LinX 0.9.5 with maximum memory at 5000MHz CPU, 4700 Uncore, AVX0 at approximately 1.34 VCore and only get to 75°C on the CPU.

    I am looking at the picture, the tubes going to the CPU and GPU do not look quite right to me.  Can that be right?
    Most of the time a tube goes into the CPU, then out of the CPU to the GPU, then out the GPU to the radiator and pump....
    And the correct ports on the GPU have to be used so the water goes through the card, not just in and out the same port side of the GPU.
    How are the GPU temps when gaming?

    AIDA stress FPU is an AVX test.  It's not as stressful as prime95 small FFT w/AVX but it's more stressful than SSE2 small FFT Prime95 (29.8 build 6 in both cases).

    I see the VCore Vdroop is on Auto in your Post #3..That will usually apply more Vcore under load (and consequently more heat) than is needed, on any mobo..That setting is a big deal when overclocking..I would mess with that and find a fixed/manual setting.
