Also the thermal paste application may be an issue, as mentioned above. Just rarely for 1 second during a boost. just started happening all the sudden. Lifting it wont hurt the cpu but will lift temps on all cores. voltage spikes at 1.45 V or higher are absolutely normal with a 3900X. This is conjecture by some random person on the internet for 24/7 overclocks. Although I do remember reading about Buildzoids 3700X degrading at 1.37v (i think that voltage… I'm currently making my first attempt at overclocking with this chip since I have the time and would like to know what is a good starting place. CASE - XPG BATTLECRUISER. Ryzen 3900X voltage Hello, I recently acquired a 3900x CPU and I am experiencing several cases that I do not know if they would be normal. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Threadripper, EPYC, Navi, the next-gen consoles, news, rumours, show-off your build and more. 3900x will boost to 4.5-4.6ghz on single core automatically if your enable PBO. It's actually dangerous because it raises the average voltage the chip experiences over a 24H period. My ... First I set SOC to 1.15V In BIOS for stability.

It does however, have the following as per the manual: " CPU Vcore/Dynamic Vcore(DVID)/VCORE SOC/Dynamic VCORE SOC(DVID)/CPU VDD18/CPU VDDP/DRAM Voltage (CH A/B) ". In theory you could tinker further using this method; reducing the voltage further may allow for cooler running, and you may have more luck in increasing frequency, it really comes down to the “silicon lottery”! Robert will make a new thread about this subject soon with an additional update. Question for you fellas: I'd to undervolt my 3900x, but my Gigabyte X570 I doesn't have an obvious voltage offset. You will see anything in this range at the desktop. .s5ap8yh1b4ZfwxvHizW3f{color:var(--newCommunityTheme-metaText);padding-top:5px}.s5ap8yh1b4ZfwxvHizW3f._19JhaP1slDQqu2XgT3vVS0{color:#ea0027} ._3Im6OD67aKo33nql4FpSp_{border:1px solid var(--newCommunityTheme-widgetColors-sidebarWidgetBorderColor);border-radius:5px 5px 4px 4px;overflow:visible;word-wrap:break-word;background-color:var(--newCommunityTheme-body);padding:12px}.lnK0-OzG7nLFydTWuXGcY{font-size:10px;font-weight:700;letter-spacing:.5px;line-height:12px;text-transform:uppercase;padding-bottom:4px;color:var(--newCommunityTheme-navIcon)} (~7200 Cinebench MT ~ 516 ST). Custom EKWB loop. I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore. Currently looking to overclock my 3900x, I've been enjoying it since July. ._3-SW6hQX6gXK9G4FM74obr{display:inline-block;vertical-align:text-bottom;width:16px;height:16px;font-size:16px;line-height:16px} Do i just turn down the Vcore? The problem i have is that, i cannot set any voltage on cpu manually. .LalRrQILNjt65y-p-QlWH{fill:var(--newRedditTheme-actionIcon);height:18px;width:18px}.LalRrQILNjt65y-p-QlWH rect{stroke:var(--newRedditTheme-metaText)}._3J2-xIxxxP9ISzeLWCOUVc{height:18px}.FyLpt0kIWG1bTDWZ8HIL1{margin-top:4px}._2ntJEAiwKXBGvxrJiqxx_2,._1SqBC7PQ5dMOdF0MhPIkA8{height:24px;vertical-align:middle;width:24px}._1SqBC7PQ5dMOdF0MhPIkA8{-ms-flex-align:center;align-items:center;display:-ms-inline-flexbox;display:inline-flex;-ms-flex-direction:row;flex-direction:row;-ms-flex-pack:center;justify-content:center} ._1x9diBHPBP-hL1JiwUwJ5J{font-size:14px;font-weight:500;line-height:18px;color:#ff585b;padding-left:3px;padding-right:24px}._2B0OHMLKb9TXNdd9g5Ere-,._1xKxnscCn2PjBiXhorZef4{height:16px;padding-right:4px;vertical-align:top}._1LLqoNXrOsaIkMtOuTBmO5{height:20px;padding-right:8px;vertical-align:bottom}.QB2Yrr8uihZVRhvwrKuMS{height:18px;padding-right:8px;vertical-align:top}._3w_KK8BUvCMkCPWZVsZQn0{font-size:14px;font-weight:500;line-height:18px;color:var(--newCommunityTheme-actionIcon)}._3w_KK8BUvCMkCPWZVsZQn0 ._1LLqoNXrOsaIkMtOuTBmO5,._3w_KK8BUvCMkCPWZVsZQn0 ._2B0OHMLKb9TXNdd9g5Ere-,._3w_KK8BUvCMkCPWZVsZQn0 ._1xKxnscCn2PjBiXhorZef4,._3w_KK8BUvCMkCPWZVsZQn0 .QB2Yrr8uihZVRhvwrKuMS{fill:var(--newCommunityTheme-actionIcon)} Mainly, I was testing different voltages at 4.25 GHZ, which was the sweet spot for that chip. Your submission does not appear to contain information referenced in Rule 1: r/AMDHelp/wiki/tsform. Recently, I noticed a sudden spike in my CPU (3900X) temperature (55-56 C) and voltage (1.4 - 1.45 V). Troubleshooting help Subreddit for all things AMD! Its suprising how little voltage is needed to run a stable all core@4.3 with the 3900X. ._1zyZUfB30L-DDI98CCLJlQ{border:1px solid transparent;display:block;padding:0 16px;width:100%;border:1px solid var(--newCommunityTheme-body);border-radius:4px;box-sizing:border-box}._1zyZUfB30L-DDI98CCLJlQ:hover{background-color:var(--newCommunityTheme-primaryButtonTintedEighty)}._1zyZUfB30L-DDI98CCLJlQ._2FebEA49ReODemDlwzYHSR,._1zyZUfB30L-DDI98CCLJlQ:active,._1zyZUfB30L-DDI98CCLJlQ:hover{color:var(--newCommunityTheme-bodyText);fill:var(--newCommunityTheme-bodyText)}._1zyZUfB30L-DDI98CCLJlQ._2FebEA49ReODemDlwzYHSR,._1zyZUfB30L-DDI98CCLJlQ:active{background-color:var(--newCommunityTheme-primaryButtonShadedEighty)}._1zyZUfB30L-DDI98CCLJlQ:disabled,._1zyZUfB30L-DDI98CCLJlQ[data-disabled],._1zyZUfB30L-DDI98CCLJlQ[disabled]{background-color:var(--newCommunityTheme-primaryButtonTintedFifty);color:rgba(var(--newCommunityTheme-bodyText),.5);fill:rgba(var(--newCommunityTheme-bodyText),.5);cursor:not-allowed}._1zyZUfB30L-DDI98CCLJlQ:active,._1zyZUfB30L-DDI98CCLJlQ:disabled,._1zyZUfB30L-DDI98CCLJlQ:hover,._1zyZUfB30L-DDI98CCLJlQ[data-disabled],._1zyZUfB30L-DDI98CCLJlQ[disabled]{border:1px solid var(--newCommunityTheme-body)}._1O2i-ToERP3a0i4GSL0QwU,._1uBzAtenMgErKev3G7oXru{display:block;fill:var(--newCommunityTheme-body);height:22px;width:22px}._1O2i-ToERP3a0i4GSL0QwU._2ilDLNSvkCHD3Cs9duy9Q_,._1uBzAtenMgErKev3G7oXru._2ilDLNSvkCHD3Cs9duy9Q_{height:14px;width:14px}._2kBlhw4LJXNnk73IJcwWsT,._1kRJoT0CagEmHsFjl2VT4R{height:24px;padding:0;width:24px}._2kBlhw4LJXNnk73IJcwWsT._2ilDLNSvkCHD3Cs9duy9Q_,._1kRJoT0CagEmHsFjl2VT4R._2ilDLNSvkCHD3Cs9duy9Q_{height:14px;width:14px}._3VgTjAJVNNV7jzlnwY-OFY{font-size:14px;line-height:32px;padding:0 16px}._3VgTjAJVNNV7jzlnwY-OFY,._3VgTjAJVNNV7jzlnwY-OFY._2ilDLNSvkCHD3Cs9duy9Q_{font-weight:700;letter-spacing:.5px;text-transform:uppercase}._3VgTjAJVNNV7jzlnwY-OFY._2ilDLNSvkCHD3Cs9duy9Q_{font-size:12px;line-height:24px;padding:4px 9px 2px;width:100%}._2QmHYFeMADTpuXJtd36LQs{font-size:14px;line-height:32px;padding:0 16px}._2QmHYFeMADTpuXJtd36LQs,._2QmHYFeMADTpuXJtd36LQs._2ilDLNSvkCHD3Cs9duy9Q_{font-weight:700;letter-spacing:.5px;text-transform:uppercase}._2QmHYFeMADTpuXJtd36LQs._2ilDLNSvkCHD3Cs9duy9Q_{font-size:12px;line-height:24px;padding:4px 9px 2px;width:100%}._2QmHYFeMADTpuXJtd36LQs:hover ._31L3r0EWsU0weoMZvEJcUA{display:none}._2QmHYFeMADTpuXJtd36LQs ._31L3r0EWsU0weoMZvEJcUA,._2QmHYFeMADTpuXJtd36LQs:hover ._11Zy7Yp4S1ZArNqhUQ0jZW{display:block}._2QmHYFeMADTpuXJtd36LQs ._11Zy7Yp4S1ZArNqhUQ0jZW{display:none}._2CLbCoThTVSANDpeJGlI6a{width:100%}._2CLbCoThTVSANDpeJGlI6a:hover ._31L3r0EWsU0weoMZvEJcUA{display:none}._2CLbCoThTVSANDpeJGlI6a ._31L3r0EWsU0weoMZvEJcUA,._2CLbCoThTVSANDpeJGlI6a:hover ._11Zy7Yp4S1ZArNqhUQ0jZW{display:block}._2CLbCoThTVSANDpeJGlI6a ._11Zy7Yp4S1ZArNqhUQ0jZW{display:none} In system while idle, it jumps like crazy from 45 to 65 degrees run a Ryzen...
