Is my 10900k power supply enough for my needs?
Is my 10900k power supply enough for my needs?
I've spent time looking up stuff to make sure my 10900k OC settings match what people see, so I needed a second opinion on mine right now. Running the 10900k at 5.1ghz with all cores running is fine because benchmarking using XTU shows max voltages of only 1.39v and the highest temp hits 80c. My voltage in BIOS is set to 1.35v with auto LLC, and when it sits idle, the voltage stays between 1.35 and 1.37v. After a bit of tweaking, 5.2ghz crashes all cores, so I went back down to 5.1ghz since I didn't want to push higher voltages than 1.35v in BIOS. Because I kept hitting 1.39v highs during the benchmark at that lower speed, I wanted to see if lowering voltage would help. Other forum people suggest that 1.3v to 1.35v is a safe spot based on other experiences with this CPU. I tried setting it down to 1.25v or 1.3v in BIOS, but couldn't get the pc stable there. It would boot up fine, but as soon as I opened XTU or MSI Afterburner, the computer started BSOD and restarted. So now my settings are back to 5.1ghz with 1.35v in BIOS, but the XTU benchmark is still showing me hitting 1.39v. Though my pc has been running completely stable with these exact settings, is that 1.39v and the idle voltage of 1.35-1.37v actually too high? Could staying at those voltages damage the CPU over time?
Your heat numbers look pretty good, even though they're on the higher side for power. You likely didn't get that lucky with your chips like some others did, but don't stress because you still have plenty of room to grow at just 80 degrees Celsius. Most folks actually hit those warm spots way too easily.
Usually around 1.3 to 1.4 volts when it's running at 5.1 GHz, based on what I've experienced.
Your temps are actually pretty good, even though they're considered high voltage right now. You probably wouldn't have made it into that top tier of winners if you had been born on a different chip, but don't worry about that because your temps are really solid at 80 degrees Celsius. Most people just burn up their chips by the time they reach 90 degrees.
No, does the 10900K just go really fast by itself even when you turn up the heat boost dial?
1.4 volts has been working well for older Intel chips. The main thing that causes fast wear and tear is too much voltage on the IOMMU/VTT chip, so I don't go over 1.325 volts for those parts. I never had trouble running 1.4 volts on first-generation Intel CPUs for almost ten years. The only damage I got was with an i7-860 where I pushed VTT to 1.4 volts.
I adjusted some settings in the BIOS. I tried setting the core voltage to 1.325 volts so that Xtu works, but the benchmark crashed. I also changed the ram voltage hoping to see if it helps, since they are set for xmp at 3600 mhz. When I lowered the ram voltage to 1.325 volts along with the cpu voltage, nothing happened. I went back up and set the ram voltage to 1.35 volts and the core voltage to 1.34 volts. Then I managed to run a benchmark where the highest voltage reached 1.38 volts. The max temp was 78 celsius. Any other ideas to keep this frequency running on lower voltage? Or does it have to be about lowering the voltage when you want to go down to a certain point? Edit: When I run the cpu on stock settings, including right after I bought the pc about a month or two weeks ago, it was set to an all core frequency of 4.9 ghz
4.8 all-core boost. I don't think it makes sense to try for a 0.3 overclock because the results won't be much better than what they are now.
Thanks. Different people have different goals. Some folks just want to make manual overclocks on Ryzen 3000 CPUs cool down better without worrying about losing speed or having issues with RAM, all for little extra effort and no real benefit.
