8700k safe voltage 21v in the bios and with a LLC of mode 5 (using MSI MOBO), the one just below the flat line curve and when stress testing, I am hitting 72 degrees C max (after an hour of stress testing) and is able to maintain that speed all the time. 270 volts for 24/7 use in Bios. 32 - 1. you can run 1. 9ghz@1. Of course if you got a good chip it could be well below 1. I also do not run it 100% at 5. 5 volts of Vdimm. 3GHz. Intel i7 8700k || ASUS Z370-I ITX || AMD Radeon VII || 16GB 4266mhz DDR4 || Silverstone 800W SFX-L || 512GB 950 PRO M. 53 is definitely the upper limit but from reading over the years many people have ran at 1. 27v. 26 or 1. Feel free to use the game boost overclock if you wish but a bios overclock will run at a lower voltage and be better. 4 GHz for video editing. 93V or . 7ghz(all cores) - I can run my 8700K at 1. /r/AMD is community run and does not represent AMD in any capacity unless specified. 8GHz you might get it down to around 1. 3 DRAM = 1. 45V with 0 degradation for 3 years. 4V, and even that is probably a bit too high for long term daily use. 29v (unstable atm) CPU-Z and HWmonitor are both showing incorrect voltages. Additional Turbo Mode CPU Core Voltage — 1,370; Offset Voltage — Auto; DRAM Voltage — 1. 7 with 1. So I can adjust it myself, right? Only changing speed. 4v safely, but I wouldn't go above 1. Save settings and reboot. The CPU voltage is increased gradually until the stability tests are passed, and the process repeated until the motherboard reduces the multiplier automatically (due to safety protocol) or the CPU I have my 8700K overclocked to 4. TL;DR - Yes safe, but it will get hot and loud. About 4. Most 2600k's can run 4. behuria; Start date May 8, 2020; Toggle sidebar Toggle sidebar. Everything goes fine when booting. ) I was able to hit 5. I noticed online that some peop any voltage is safe with appropriate temperature. 0ghz@1. Then there's RING OC etc. true In any event, knowing the maximum safe voltage requires you to know the maximum amps rating for the chip, how many amps you are pulling at load, AND accurate voltage reading (amps can be calculated). For me on an Asus board, I turned of MCE initially and I was seeing high 60s after 60 minutes of running prime95. I can read in the CPU's datasheet Maximal operationg voltage 1. 2 or 1. Yes, it's safe. Monitor your vcore with cpu-Z. If you keep temps under control, what is the safe voltage for vcore? Got a sample of an 8700K machine and now trying all sorts of combinations to overclock it. 02 if the motherboard allows at that scale. 5. 28) it pass realbench 2 hours,aida64 cache 2 hours,prime95 1344k Along with safe maximum voltages for 8700k, mainly I'm looking for what will help stability for above said example. 45V if you have a good AIO to keep temps in check and would only really recommend 8700k, 32GB RAM, 970 strix, asus maximus x code. Save Voltages for light overclocking, 1. I managed 5ghz all core with the cache at 4. 8 with 1. 35V, but I cannot remember for certain. I do run a custom loop however and the CPU rarely sees above 60c. I can only guess what an 8700K would So recently i had my i7-8700k at 4. They don't allow you to apply an unsafe voltage through your GPU. 12V all day long and not notice any problems whatsoever - with the exception of the torture test. 39 volts, is that safe? (Sorry if that is a dumb question, haven't done this stuff very long) it's safe for benchmarking, for 24/7 use if you want the chip to last a couple years i'd suggest bringing it down to 1. I currently use it for gaming and streaming, but would like to move into music and video production in the future. 344V, although this happens when I am using the CPU at 100% load, using CinebenchR15. 7ghz without any errors or crashes during 4,9ghz at 1. 52V but I'd recommend staying below 1. Its temps at idle moments vary from 40c to 50c. 4v it also would be perfectly safe. As for the motherboard, 4. Cooling is an H100i and max temps under stock stress testing are ~50c. I want to use multicore enhancement as an easy one click performance boost. 240 volts, and ran at that temp for 2 minutes till run was finished. 2 and 5. I am using a 4 1/2 year old [as of this writing] i5 3570K and run it at 4. 7 and voltage at 1. 8ghz on all cores would be fine. This did ofc degrade it, but only for ~1 multiplier at same voltage. 35 Vcore will consume ~170 Watts running a true 100% workload, which is P95 Small FFT's without AVX. But first, to establish the overclock stability, i advise you to desactivate I managed 5ghz all core with the cache at 4. 45. 130 through Intel XTU, so that I could just uninstall the software if it Electromigration is kind of a long term deal at these voltages and the 8700k is gonna be obsolete before that's a problem. 5GHz is kinda close though, since the VRMs of this mobo are rated at 160A max while 8700k can draw 130A continously while stress testing with Prime95. CPU: i7 8700K (5. 370v will peak at about 80c with 68f ambient in prime95. 6GHz at 1. 7ghz between 1. Id definitely put a bios cap on watts if I was going to go over 1. 35 should be plenty to get it to 5 ghz, depending on the silicon quality obviously. With any 3rd party auto overclock you'll thermal throttle from the excess voltage before the voltage becomes scary. Overclocking the Intel Core i9-10900K (Comet Lake) to 5. 45v you'd need at least a 360mm rad. 32. CPU Core/Cache Voltage: Voltage of the CPU cores and cache. Although that still looks like a high temperature to me. 3V VCORE. Basically got a 8700k with a 240mm aio. Everything else was left at default or Auto. 3530. As for long term degredation it's Impossible to say. The main things you need to worry about Maximum safe core voltage offset for i7 8700k? comments. In your case I suspect you can go much lower since You should not need much vcore for that and I would just leave that at stock. 1? I’d like to start low and then go up if that doesn’t work. There you have a pretty much guaranteed safe overclock. This is why it is important to keep CPU VTT within . 7 GHz is considered an Overclocking should be an iterative process where you increment clock speed and only increase voltage as needed. 1. have a droopy LLC, this is good for voltage regulation but side effect is higher light load / idle voltage load voltage and light load voltage is very different. 28v at max during full load. I can also read that note *7 states: "Long term reliability cannot be assured in conditions above or below Max/Min functional limits" Posted by u/[Deleted Account] - No votes and 21 comments Set your voltage to 1.

I've written some detailed posts on this (for the 9900K/9700K/8700k, etc) but the same math applies to any processor when you know the max amp CPU core voltage = 1. Expected Cinebench R15 results for specific clocks are also welcome so I can find phantom throttling if any. 5ghz and saw my highest CPU temps after roughly 1 hour of AIDA hit 74c per core. Not worried about running it at such a high voltage because it should be safe anyway and it only spends the time I'm actually in game running at that volt. I turned on Intel Turbo Boost and Enhanced Turbo, so my 8700K is automaticly set to 4. 4 really is the max if you want to keep your CPU for a Very low 30's degrees C (28 to 32c) is what you should be getting Definitely not getting that low of temps idle. 310 volts, with adaptive voltage mode on, voltage fluctuates as high as 1. Has this permanently damaged my chip whatsoever? Additional Turbo Mode CPU Core Voltage — 1,370; Offset Voltage — Auto; DRAM Voltage — 1. That is for the safety of the CPU and I'm not sure Are these settings/ this configuration safe? Especially regarding the voltage being on auto? Will auto voltage give more voltage than I actually need and if so is that safe anyway? my 8700k@5. Is this normal? I've seen OC'd 8700k's running 5ghz at 1. 8700k`s have better cache than previous gen and can clock higher with ease running 1/1 does benefit in some situations`s EDIT: and yes maximum for safe voltage would be 1. And what about voltages? I know that the voltage is what can kill components, along with temperature, so what is the safe range for a G1 Gaming 970. Sometimes with Auto Voltage it is pushing way more then it needs. The one below IA max turbo limit is still on Yes. Ran my 8700K @ 5. e ST), depending on the silicon characteristics. 3v. XMP on.

But there is reports on the internet (including this week on this form) of voltage degradation at or around 1. 1-5. 35 VCCIO = 1. 350v with a max value of 1. Thread starter siddharth. Raise your multiplier gradually. Home. 4GHz on all 10 Cores If you keep temps under control, what is the safe voltage for vcore? Got a sample of an 8700K machine and now trying all sorts of combinations to overclock it. g I've set a manual voltage for my 8700k, but according to HWinfo it stays at that voltage even when the cpu is idle frequency. No need to delid unless you're chasing over 5Ghz clock speeds. there’s a beta bios fix related to Vcore I been running my 2600k at 5ghz 1. 2 at that voltage. It usually stays in the low 50s while gaming. 4GHz still wouldn't be stable, you're up to clockspeeds where you need a really good chip to get stability without pushing past the safe voltages and breaking out the exotic cooling. 25 TB Once you get to instability increase the voltage slightly. 095 volts is all I needed for playing games stable. The VID is simply the voltage bin requested by the CPU but the Vcore is the actual voltage applied (at least as far as the onboard sensors can read, you need a DMM to be more precise). 314v VCCIO: 1. I hope the CPU will allow this frequency on a relevant normal voltage up to 1. Nevertheless, it’s not View full post. I have not run any stress test, but my PC been running for days very stable in everything, gaming and all. 45V for a year without issues, and 1. 28v and LLC at Level 4 (Asus Hero X - Newest Bios Version) - Where my lack of understanding comes in to play is when it comes to the voltage readings. 2 Vcore @ 4.

They don't test chips other than protypes for minimum voltages, they'll just set a high enough voltage to cover any discrepancy. I checked UEFI and my voltage is set to AUTO at 1. Currently CPUID shows my voltage at . 4v is still a safe voltage as long as your cooling can keep up. 45v. 45v with LLC5. I overclocked the 8700k to 5. 4v is usually consider the safe maximum. 4v which got me worried. Well this seems stable currently at 1. Enhanced sync or whatever they call it these days is a function added by some motherboard manufacturers and it adds an overclock that pushes all cores to 4. Be aware that even if the temp is safe for your CPU, running your coolant above say 60-65C is probably out of spec for your You can set a voltage manually with adaptative mode which let your Vcore fluctuate with the load. 28 v for 5 ghz My 9900 ks 16 threads not delided needs 1. 4v is safe but yeah it's unnecessarily high. 2 CPU and 4. 3 now. Discussion @4. 42Vcore (llc l6) for about 1710/230 Feel free to use the game boost overclock if you wish but a bios overclock will run at a lower voltage and be better. 386v dynamic offset, turbo LLC (gigabyte, Extreme is highest), 1. I’m gnna play it safe and run stock until more bios updates. My motherboard is a asrock z370 pro 4. This is a good and safe starting point even if you have a good chip lower voltages will help to keep temperatures lower, start here if you are air cooling. Start by setting the voltage and core multiplier to near default values. I also understand that there’s an offset who’s name eludes me, AVX or similar, which I have set to -4 My aim is to get somewhere around 4. Now that we’ve managed to overclock the Core i7-8700K to 5. For the voltage 1. 4ghz at 1. 345 for 5. You'll also notice in the video I recommended far lower voltages for people starting out. Generally it is not a useful reading in HWinfo. 3v 12 hrs - 24hrs stable in prime or occt linpack is a nice chip . 4 or so and delidded 4. 2-1. 7 instead of 1. 3V is safe as f**k (anything below 1,4V is fine). 37V under load with LLC5. As a voltage i set it to 1. 5 volts for 6 years. 5 volts and 8 years later we see its been no issue or degradation. I set my BIOS as you suggested except for CPU SA Voltage mode suggests variants not numbers (like the core voltage mode) so I left it Auto, then CPU Aux Load line calibration only has 2 modes, not 6, so I left it in auto too, and I don't have TA CEP support but rather IA CEP Support (swithced to Disable). You can play around with you multiplier and voltage without worrying about damaging your CPU. If your Vdimm is 1. I am using 16 gb ddr4 Corsair Lpx 3000mhz. I'm going to buy my 8700k from them,binned and delidded. 5, 4. Max safe is 1. 3. 130 through Intel XTU, so that I could just uninstall the software if it Intel 8700k Safe Temperatures . So i was wondering if using a fixed voltage could accelerate degradation overtime since it's not fluctuating even if it's that low ? Safe overclock for 8700k . And a stable one, though maybe I could go down Here is a c/p about VID voltage reading. Don't be scared to give the puppy a little juice, it won't get hurt. So at idle, cpu Z states my core voltage is at 1. Any thoughts are appreciated friend (I've been researching my best tho). 05v are pretty good upper limits. By JHurley7nrx February 22, 2019 in CPUs, Motherboards, and Memory. 05 now and run 0. 80°c is safe if you're at a lower voltage eg 1. I then turned on core linking, set to 4. The only safe voltage is the one Intel shipped it with because if it fails you still have warranty support to replace it. If you're going to overclock and don't want to delid, you're probably going to By safe, I mean the method, used for overclocking, is right. Is is safe/ok to use Override CPU voltage, set for full load stability, when I'm allowing the CPU to downclock during idle loads? Honestly I don't have a low end board but my 8700K hits a wall at 5. 35 volts is required to push that frequency.

This is the peak test: Any 8700k 5 ghz under 1. true Any insights where I might start looking at safe easy OC at with a Auros gaming 5 mobo/8700k/Noctua D15? I couldn't find much on what is the real protector from voltage damage or what I really need to consider in terms of lifespan reduction. To be It's a long process, but in the long run its safer to explore the performance limits of your CPU this way. 2v vccio and vccsa, 1. Hi, I'm having troubles setting up adaptive voltage on my motherboard and I am thinking of just leaving it to manual 24/7. 0, take the 4. Up to a certain point of have a droopy LLC, this is good for voltage regulation but side effect is higher light load / idle voltage load voltage and light load voltage is very different. I do increments of . 5v for a few benchmark runs is different than extended gaming sessions, hours on end. Intel i7-7700k @ 5. 4V. Either in BIOS or with XTU. I haven't yet heard of instanta pops at 1. Next, set a safe manual CPU voltage—around 1. By Shaan5 April 17, 2015 in Graphics Cards. 35V because Intel said for Sandy Bridge this was the safe limit and as the transistors get smaller so does the voltage needed to make them Max safe voltage is always an ongoing argument. 278v and have no issues on temps. I been running my 2600k at 5ghz 1. Still passes stress tests at the same speed and voltage it always has. 35V but we really have no idea what safe voltage is, its unlikely to be above 1. I started a program to see the voltages, and when it was at ~4. It's very possible that with elite cooling and voltage bumped up to around 1. I don’t want to destroy the life of my CPU, but i also don’t want to gimp my PC because I’m stuck at what max Any insights where I might start looking at safe easy OC at with a Auros gaming 5 mobo/8700k/Noctua D15? I couldn't find much on what is the real protector from voltage damage or what I really need to consider in terms of lifespan reduction. Add a Comment. 4 which is what I’m at and even then I stick with a -2 avx offset so that it runs cooler when I’m doing tasks that don’t need the There is a massive disparity between the reported VID and the actual Vcore. 8/4. 3v on vccio or vccsa as there is not much need for going any higher unless you run seriously fast memory. Max safe core voltage for i7 8700K? I currently have mine set at 1. 48v at times in HWmonitor but my temps are sitting right around 33C. 30V max for air cooling and 1. 15 or higher to be safe. Oddly the voltage seems to go much higher while it’s at idle, but with the adaptive voltage my initial testing is showing it to be stable. And the voltage was way too high for my taste, so I lowered it by 0. If all goes well you can lower your voltage to 1,34 and try cinebench again. 40v the h115i should be fine, for 1. What would the absolute maximum safe DRAM voltage for daily use for my RAM and CPU combination? I have an i5-2500K that's overclocked to a stable 4. ~ The Stilt. This voltage controls the core i7's memory controller and connects it to the RAM. When stability testing (Aida 64 & Cinebench) i'm getting VCore readings as low as 1. 28v at 4. Kind of nullifies the point of this thread as you need to be testing the same processor with the same thermal paste in the same system at the same ambient temperature running the same bemchmarks to get results that are anywhere near relevant. 4 volts. So I have my 4790K overclocked to 5. Thanx for your post. 65v range, anyone have any arguments against said assumptions? Jump to content. 9Ghz for the 8086K. 2v and go up or down depends on stability test result. Turbo clocks are considered overclocking as any frequency above the stock 3. For sure not for max, maybe a little in future with a safe range without problem with temperatures. So, i turned on my computer after that. Hi, I have a Asrock Z370 Taichi Motherboard with a i7 8700K at 4. 8Ghz for the 8700K, 1. Set it to balanced and when no load is detected it’ll clock down. The max safe voltage is set as the voltage which under the maximum workload (ex. 1 54% 5. 1ghz so i decreased the voltage to get the lowest Vcore possible for a stable 5ghz and i'm now at 1. 370v set in BIOS but in Windows under load it's 1. for regular use it is in the 72-77c range depending on how hot it gets in the house 8700k Safe voltages for OCing . While it is safe, its a big jump in Cpu core/cache voltage (manual mode)-Cpu core voltage override (1. 35V and my Core Clock to 5GHz, and boot it, CPU-Z, detects a Voltage jump and it goes from 1. Each cache tier gets larger but slower, with RAM Hi, i'd like to undervolt my 8700k to approx. 40v on the core unless you have delid with liquid metal and very good cooling. I was wondering if it is safe to have a high Load Line Calibration and keep it at a fixed 1. 42Vcore (llc l6) for about 1710/230 Here is a c/p about VID voltage reading. My 9900k can do 5ghz p95 small fft on 1. 0Ghz right now with 1. 35 to 1. 42Vcore (llc l6) for about 1710/230 Ran my 8700K @ 5. I would look at the settings that the EZ tune uses and manually input those into the BIOS, but lower the voltage slightly so that you can run cooler and have quieter fan profiles. If it takes 1. Then increase voltage until it's stable at the new speed. 8700k and 8086k are the same physical chip, 8086k is simply binned to hit 5ghz, and thus will usually require lower voltage at any given frequency. CPU will thermal throttle at Tjunction 100C before any damage occurres. 8GHz overclock is fine. 7GHz it said 1. 5V with LLC at max level (very very bad practice) for another year. IA: Max Turbo Limit on Yes And while on no loads on desktop I change my cache multiplier live I can get the Ring: Max VR Voltage, ICCmax, PL4 reading to say No, at all times, even under load. 4V, but the temps will be wayyy to high for an 8700k without delidding. 51v for 8 years and my sons 2600k has been at 5ghz 1. 45V if you have a good AIO to keep temps in check and would only really recommend - There's no a true maximum safe voltage. I am cooling it with a Be Quiet Silent loop 360 (AIO). I have the "parallel" Gigabyte motherboard, and they're almost exactly the same. 0GHz, let’s check out the full load temperatures on our next page Related articles. 8700k 4. Although GDDR5 is more like QDR RAM, I expect the max safe voltage to be in the 1. My 8700k left on auto bios settings can get up to 1. I can also read that note *7 states: "Long term reliability cannot be assured in conditions above or below Max/Min functional limits" Any over clocking forum the " 100% safe 24/7 cpu volts is 1. 200 bucks cpu as good as matches the 8700K Except gaming that most people do. with more than 2 dims populated. I'm just wondering what a good OC is without pushing boundaries too hard. 2v. Advanced Menu: HyperThreading have a droopy LLC, this is good for voltage regulation but side effect is higher light load / idle voltage load voltage and light load voltage is very different. The problem i have is that i tried Offsetmode -0. Search titles only (reduce Core speed and voltage) to protect against thermal damage. 25 to achieve 4. 1 GHz OC). Hi guys, i'm trying to overclock my i7-8700k with asus maximus x code board,so far my chip is stable at 4. 2 and I get the same temps doing the same thing. Forums. 328V to 1. 7ghz without any errors or crashes during Naturally I'm very paranoid and apprehensive about everything. 98V (can't remember) should be the safety limit for VTTDDR and that translates to 1. Maybe I’m old school, but I typically think like above 80C should be avoided. 7GHz but basically does 4. 7GHz, how to undervolt? Hi, my mobo is MSI Z370 Tomahawk. 8 Probably could have used less voltage than that. 7Ghz with a cpu vcore of 1. As for voltage, you shouldn't necessarily use the auto voltage when overclocking as it will usually overvolt the chip. 9 and leave it. 9 99% 5. I immediately turned the computer off again.
