overclock 6800k following bios update
Following the latest BIOS update (1801) for the Asus X99 A II motherboard, I successfully overclocked to 45 Ghz and achieved stability during tests such as Cinebench and UserBenchMark. Prior to this upgrade, my maximum overclown was capped at 42 Ghz. The system features an aio water cooling solution with Arctic Liquid Freezer 240, maintaining the CPU temperature below 72 degrees Celsius. I’m still uncertain about the exact Vcore values. This screenshot captures the Open Hardware Monitor readings after two hours of testing.
Sorry, is there a question in there?
I’d prefer to test an older version of Prime95 or Aida64 for a longer time before calling it "stable," though. Cinebench and similar tests are fairly fast.
Regarding VCore, are you enabling auto in the BIOS? If yes, it might mean over-voltage is active (common with auto mode).
You can use tools like HWMonitor to check the voltages during load—feel free to share a screenshot if needed.
there is a reference to a screenshot of the ohm in the original message (in the preview I couldn't see the image, which is why I shared a link; I'll try again here). the vcore is set to auto, and I'm not entirely sure about the settings I should adjust, so that's why I left them on auto.
Sorry, I didn't catch the link.
There seems to be an issue with the detection at 4.5GHz—no valid reading possible.
Consider running a real stress test instead of a benchmark.
The maximum Vcore for Broadwell-E... is generally considered to be around 1.2 to 1.275V.
Prime 95 recently crashed my computer due to a Timewatch/Dogwatch timeout error, specifically version 29.4. I haven't located an older version on their site yet. Could you share any details from HWMonitor or the BIOS that might assist with this issue? The system handles tasks as expected.
Prime95 26.6 was the final version that didn't rely heavily on AVX instructions. If you avoid AVX workloads, testing becomes more logical:

RealBench is another choice, focusing on more typical AVX configurations:

Your overclocking might be reliable for now, but it doesn't ensure long-term stability when you switch to different programs or settings.
Both tests failed right after starting. The real bench handled the task much better, not crashing the whole system like Prime did. Should I consider adjusting the vcore in the BIOS?
Could you help me understand the parameters I should use?
UPDATE
Sorry for the confusion earlier; during the BIOS overclock I also made these adjustments:
-cpu cache override: 1.100
-dram voltage cha chb: 1.350
-dram voltage chc chd:: 1.350
-vccio cpu: 1.0500
-vccio pcm: 1.0500
UPDATE NR 2
I switched the CPU cache voltage override to auto, set the clock speed to 44 GHz, and in HWMonitor the CPU Vcore stayed at 0.968 maximum during Prime 95 for over 15 minutes. The system is stable now.
CPU core temperature reached a peak of 70°C.
I’m really satisfied with this performance.
I’m curious if I can push more performance without going overboard, I was fine at 42 GHz too. After the 15 minutes, the computer stopped beeping after just 1-2 minutes. I’ll open the case to check the motherboard code.
Also, in the real bench it sounds like the system shuts down quickly—no clear reason, but I’ll look inside to see what’s happening.
