this is the only guy that actually knows anything about overclocking on youtube, keep the vids coming brother!

Yeah, thank you for this video. 99% of r/overclocking have no fucking idea what so ever

I'm so proud that I'm your subscriber. Thank you.

i still don't understand why you are at only 9k subs you deserve so mutch more KEEP IT UP !!!!

Very informative channel mate. Thanks for sharing your knowledge.

Dude, I think you do a great job with your videos. You definitely go waaaaay more in depth than anyone ells. I'd listen to your recommendations looooooong before I'd listen to any of these other jokers on youtube. IMO they just want easy money. You take your time, and dissect every aspect of every angle, which IMO is good. Pretty much everyone ells tries to be funny and entertaining, maybe that works for their channel, and that will get them all the "kids" that wanna "game", but when I just want some solid information. I know this is the place to be.

Thank you for the explanation on why CPUs clock so much higher on LN2. I've always wondered that.

YOU ARE GREAT. you make OC great again ^^

FIRST! BTW is the new mic better or worse?

Kudos, thank you, very informative!

as always , a very good video. How does the in internet voltage regulator in the haswell (e) en brodwell (e) serie's effect the termperature of the chip ? And what would be the influence of the input volt to the Vcore conversion for that matter.

Excellent video very useful indeed

It's safe to run on Prescott and somewhat borderline safe on Conroe. And even that is at the limit. Not sure in which way the TriGate differ to planar gates, but obviously not up that high. Would say even 1.4v is critical on 14nm

If you want to push over 1.5V, basically grab some chips made on a FD/PD-SOI process. Which basically just means Piledriver, or any POWER CPU you can get. FinFETs is more practical with where the market needs are, but I very much hope to see 22FDX/12FDX adopted also.

I've actually had Quad Q6600 running on 1.5v for like 8 years and it still worked (and probably still works, still got it laying around somewhere with old mobo) until I upgraded my PC a year and a half or so ago, granted it did have an impact on the health of it, by the end of usage I was only able to get it to run stable at 3,4ghz, at it's prime time it was able to run on 3,9ghz

Nice mic and knowledge. Thats max default vid is about 1.52v, but that without load line calibration i think.

can you talk about VTT/QPI Voltage please? Is there actually a reason to play with it? i bought a GA z68xp-ud5...i wanna pump up voltages.

Great Video! Thanks. It will help my that I'm not going to destroy my i7-7700k. What's the best programm to test the stability of ram-overclocks?

@Actually Hardcore Overclocking What max voltage would you recommend on coffee lake CPUs? specifically the i7 9700k? and what about temperatures as well? I would like to run it for daily usage but not 24/7 e.g up to about 8 hours per day or so at most.

FYI the old Intel P4 1.5GHz 423 CPUs run 1.7v and a lot of 478 CPUs run more then 1.5v just so you know great video tho lots of good info in it thanks again

Random question not in context of the video I understand if you don't answer. What do you think of the ASUS STRIX Z270F VRM? I just bought one to pair with a 7700k and I plan on overcloking to maybe 5.0ghz or so if my chip will do it. I kind of jumped the gun and now I'm thinking the gigabyte K7 would have been a better choice in the 200 dollar price range in regards to the VRM, the K7's VRM just looks more robust. Does it even matter that much? Love the channel, I have learned a lot from your videos.

so if the CPU degrades not by voltage but by current... can i use the measured power from aida64 and then divide it by core voltage (EG: 105 Watts/1.46vcore -> 72amps)?

So what is the Vcore limit for Haswell-E/Broadwell-E?

Sound is good.

Where can I go to get info on tuning my 5820k? I'm at 4.6GHz 1.35v(IIRC) on all cores with speedstep disabled and I'm desktop/game stable all day, but not synthetic bench stable. With my current cooling I'm not willing to increase the vcore much and I'm not even sure how high is advisable for Haswell-E.

good stuff buildzoid... i buy hardware and build and sell systems for a living... Gone through at least 40 unlocked i5 and i7 chips in the last couple years. only ever had a problem with my own personal 6850k. One night it went out and the system wouldnt turn on the next morning... i did have it running at 4.6Ghz. 4.7 was possible. (never seen another BWE chip like it) voltage was set to a constant 1.388 and through every bit of monitoring software i would run as far as i know it would stay constant. However the bios on my x99 Sabertooth would read significantly higher... 1.6v+... i always just figured it to be off in the bios for whatever reason... i RMAed the chip, but not after testing multiple psus, rams, gpus and motherboards... everything else always came up fine. i had no choice to conclude it was the chip. im still waiting for a new one but honestly... im still not convinced. i dunno... anyways thanks for the video, loved it.

the vid table for imvp8 is in an richtek as seen www.richtek.com/assets/product_file/RT3606BE/DS3606BE-02.pdf on table 1 and it maxes at 1.52V

Great video, thank you! Got a 4770K @ 4.64Ghz @ 1.28V VCore & Vring 1.85V CCIN - delidded (not liquid metal yet) at 80°C max. Looks like I could push further for a long term use. Does somebody know by how much the internal resistance of a CPU will lower when cooling it lets say by 10°C better? Or how much is the internal ressistnace dependant of a CPU dependant on temperature?

Please one question, I run almost 1,5 volts on xeon 5675 32nm for a couple for hrs to test if its stable... it wasnt so I rolled back to lower stable oc. Could I have degraded the cpu? It was set on vid max 1,492 volts on 4,7 ghz... now I roll to 4,5 and I get bsod sometimes... did it degrade???

I believe in a max safe voltage of 1.4v. I think you could 25/7 that with little degradation over the years. 2500k just overclocked for the first time with a vcore of 1.33v at 4.6GHz. Might up that to 1.4v and give 5GHz a try, but i digress. Feels a little close to the 1.45v max recommended from guides and whatnot.

I have a question about undervolting, can it degrade your cpu or cause some hardware issues ?

What would you say is a "regular (ok)" voltage for SB before passing the limit?

Your comment about amps killing silicon reminded me of my GTX 660. Or rather, my three GTX 660s that died and were sequentially replaced by warranty (thanks EVGA!). They all died while playing PlanetSide 2. Apparently hammering the GPUs at 100% load at 74 C just irreversibly degraded them very, very quickly. At first they would just artifact, then they would start artifacting REALLY BAD, then they would start crashing. If you had a 660 around it would be neat if you could.. uhh.. reproduce this (like you'd want to kill a GPU) It's kind of funny because my R9 Fury Nano is sort of doing the opposite. The longer I run it, the less it artifacts and crashes... I don't know man, Fiji is weird. [1240 mV, btw)

So using an online calculator, at 1.45 volts the cpu would be drawing 138.3 watts and 95.4 amps assuming a .0152 resistance? So Lowering the temperature also lowers the resistance giving you more head room? and conversely higher temps increase resistance? i assume there are maths to calculate temps impact on resistance? Sorry for the n00b questions.

Are monitoring programs like hwinfo accurate for CPU power draw?

So how do you determine current? And where can I find the max safe current for every CPU?

I'm just thinking that would you consider hiring an editor for your videos? Also would you be okay if I tried to edit some of your videos? I'm pretty sure that trying to record these in one take is hard and time consuming.

My 6700K is currently 4.7Ghz with fixed 1.385v 24/7 on air.

So what's the safe limit for FX chips? Although I suppose mine will only be around for another month or so, running at 4.2Ghz 1.4V, didn't get a too great an FX 8300 though I suppose that's to be expected

lol then theres me when i first overclocked my 3570k and gave it 1.64v for a couple seconds because LLC is smart (set to 1.3v for 4.5ghz and not under load at the time) and btw you didnt link that asus overclocking guide you talked about in the video

I have a 6700k and an Asus Sabertooth z170 s motherboard. Auto vcore is set to 1.316v (BIOS reading), software shows a max of 1.424v. Obviously this is high and results in high temps at stock (above 80c at load). I've tried clearing CMOS and different BIOS, still get same auto vcore. I manually set the vcore to 1.2v and the BIOS reads 1.216v, software shows 1.226v max. It's completely stable at this voltage, temps are well below 70c at load. VID still shows requests for over 1.4v though. Could you offer any thoughts on this, as far as the safety of this auto vcore and why the hell Asus would set it so high? Thanks!

Dude i need your help!! I installed rx480 (Sapphire 4gb, no oc) on the old mobo, worked like charm the first day.. Today i get random colored lines on the splash screen of the mobo manufacturer only (GA-P67-DS3-B3). Post doesn't have them, booting in the windows doesn't have them, when in windows not a single issue, multiple hours of gameplay no issue.. I've noticed that the fans of the card ramp up hard when starting the PC.. Any help would be nice..

Can I calculate the amps of my cpu/gpu ?

my brother wanted to undervolt his 4670k, instead of 1.09V he put 1.9.. it booted and ran no problem. but after realising his mistake he pulled the power and cleared the CMOS. after 30min he got it to boot and it works at 1.3V locked to 3ghz.. sooo. is the core dead or do you think underclocking the memory could work?

Have you read this document? ieeexplore.ieee.org/document/7112692/authors I realize it is talking about voltages mostly, but it is talking about overall reliability and shows just how much stronger the Skylake and Kaby 14nm nodes are than 22nm was.

it is safe to run at 1.5v it will just not last longer than the warranty.

is 1.7 volts at sandy bridge memory controller ok ?

Hey I have a question. About a year and a half ago, I accidentally set my vcore to 1.92v instead of 1.29v on a i5 4690k and ASUS Z-97A. When I booted, it instantly BSOD and realized I fucked up. Two years later, I'm running the same overclock of 1.26v at 4.4GHz. Why didn't my i5 4690k fry itself???

voltage cpu amd 3820 msi 990fxa gaming ???

Not related to the video but I got my 6600k stable at 4.5ghz with only 1.225 vcore. From what I have read generally People need alot more then that to get them stable, have i missed something or is my chip a golden one?

Buildzoid, my old CPU is a x5690 on an old 1366 socket x58 board. Here is my spec sheet. www.intel.com/content/www/us/en/power-management/voltage-regulator-down-11-1-processor-power-delivery-guidelines.html It says ICCMAX is 145A and max peak vddc peaks at 1.6 for a very short time. I run stock vdroop with 1.49vid, is this safe on water given temps and vrms stay nominal? Thanks in advance buddy

My 10875H idles at 1.52 VID stock...

My 2500k has been at 1.5 at over 4 years and still runs 5Ghz fine.

your motherboard VRM shall outlast your cpu degrading? Are you insane? Obviously you never had a sub 100 dollar Asrock-Board. Wonder why 2nd hand 1155 Boards are literally dying out while i never saw a dead cpu. For each 1155 Board there are probably more than 2 chips on the used market now.

that's odd, all i see is people afraid to go near 1.4v, maybe cuz i dont look at reddit for hardware

I ran my sandy at 1.52 5ghz degraded fairly quickly.. 6 months or so beforei had to drop clock. It still runs to this day. (sold it a few months back) but max stable clock is 4.4ghz

Ok, let`s switch to default frequency 4GHz with 1.2 V ? =)

Every chips different. The lower the voltage the higher the probability of increasing the life of the chip.

so tldr 1.52v is safe. just don't exceed your CPU's max current. weird way to present the video. yeah if you crank up the p95 you'll hit those amperage limits.. but if you're trying to optimize for a particular game and have a good way to benchmark the game (e.g. custom map the simulates worst case scenario), you can find a safe level below max amperage.

Northwood pentium4 ran over 1.5V stock.

3:20 lol

Somehow lol

Just let them put it at 1.52v and blow their shit up. =D

Lul, FX 9590 its set to 1.9 V by factory

If you enroll in Intel's Performance Tuning Protection Plan they'll send you a new processor if you accidentally fry yours trying to overclock.

1,52v is save if you not overclock and leave it 24/7. 1,52v is not imediate danger to the CPU. 1,52v is ok for 24/7 if you use the chip for 2 years and buy the Intel new one which they sell you every couple of years. That is what this data sheet means. I like you to put links to the data you show in the video. Its useful. BTW I used my 2500k on 5100mhz on 1,52v but it wasnt 24/7 but for workloeads and gaming for 3-4hours max.
