8700k Overclock- First Time

[Sgkpt]

Hey guys, I finally decided to try out overclocking for myself. I have an 8700k, no delid, ASUS Z370-E, and a Corsair H150i PRO RGB (push/pull, included fans plus 3 LL120's). I've built systems before, but just haven't tried OC'ing myself, so I am familiar with the parts and the jargon. I tried the ASUS 5G OC profile that's baked into the motherboard, it seems to be trash, voltages go up to 1.4-1.5 (ow). So I reset the BIOS and retried from scratch using my own values. Set ratio to 50, (5.0 GHz), turned on XMP, and changed voltage to a manual 1.30, also the multi-core enhancement is on. At 1.28 the pc goes straight to BSOD on boot, but 1.30 has been stable for a while now. I'm using AIDA64, CPU stress test only. Maintaining 68-70C on the CPU, hottest core maxed out at 77C, CPU max was 74C. Now for the questions! 1. Should I check off other boxes when stress testing? In the real world I just game, AAA games, but that's it. I do homework and game, no editing or server workloads. My understanding is that the FPU test is only relevant for people using AVX instruction sets, correct? 2. Are there other settings I should look at in the BIOS to maximize my earnings? Should multi-core enhancement be on etc.? 3. Should I try and push the clocks to 5.1-5.2? I know that it wouldn't make a real-world difference, but going from 4.7 to 5.0 doesn't either, so in your guys opinion would it be worth pushing my luck?

Any other information that I can provide I'd be happy to!

BTW, case is H700i, there's a fourth LL120 at the back exhaust, plus one stock NZXT 120mm on top, and 2 120mm HD RGB fans up top. (H150i is at the front as intake, push/pull)

When I'm stress testing with AIDA64 I use CPU, FPU and cache all at the same time. 

FPU is brutal temperature wise, so if you can keep temps under 90°C on FPU test only ... it won't ever overheat during normal workload

Well if you feel like it. I tend not to do it as much as I can on any cpu as it yields almost nothing for me. 

My old cpus can’t do much being old. 

 

The new one seems to hold its own just fine at 5.0 or 4.5. So less voltage and less heat and less noise will always be my preference. Especially when it runs at 90%+ most of the time.

we use the same motherboard and CPU, mine can do 5.0ghz at 1.28v and 5.1ghz at 1.35v but i'm running it at 4.8ghz and 1.2v because it's simply not worth the heat and extra noise to get absolutely nothing back in terms of performance gains or anything...in gaming i'm 100% GPU limited all the time (1080ti/1440p/high refresh) so i'll keep the ''overcooking'' for later in a couple years if i find i need the extra performance for my RTX 4080ti or whatever

 

There are a few things in the BIOS to change off the top of my head you can increase max current distribution to the CPU to 140% (this is important) and a few other stuff i don,t remember...

 

But IMHO you should settle to 4.8ghz and see how low a voltage you can go and lock it there until CPU is a few years old and lacking.

But is it worth even using the fpu test then? Also I now am getting bsod's when checking off stress FPU. need more voltage?

Now when I try stressing the fpu or use prime95, not Aida, I get BSOD's. Would this mean I need more voltage? If so, I see what you mean about just running at 4.8 instead....

Pretty much the same here. I can get 5GHz at 1.27v and 5.1GHz at 1.3v. I'm also running 4.8GHz at around 1.2v for reduced heat and noise.

 

i7 8700K + ASUS Z370-G WIFI AC

Went back in, loaded the 5G profile, so that the current would be set to OC, as well as some internal power management settings, then just changed the voltage down to 1.33. Now I'm getting max of about 90C, but AIDA doesn't report any throttling, and this is with FPU turned ON. I will try for 1.32 etc and see what happens. Looks like not changing the current is what my limit was, not the voltage.

yes it means it's not fully stable...but depending on what you do with your computer...sometimes ''not fully stable'' can also be fine for you if you only play games and it doesn't crash while gaming or other stuff you do on your computer then it's fine...if you're not doing serious work where you dont want to loose data and stuff...it depends...

[Sgkpt]

Well, I think I'm done now. 4.9GHz is easy at even 1.30 volts, but 5.0GHz requires a full 1.4+. This 1.3V 4.9 GHz clock yields max temp of 78 on the CPU, including a FPU stress. Bump it up to 5GHz, needs unsafe voltage and it hits 94 easily. So screw 5GHz! I guess the sweet spot for this chip is 4.9, and that's good enough haha. I guess that's the silicon lottery.

Well 74c without overclocking is high.  If you raise the voltage and overclock it that 74c will be in the 90's c.  Possibly damage, but CPU does shutdown after 90 or 100c depending on which CPU you have.  This is my hunch, not saying Im right or anything.  Is 74c on stability or stress test ?  If so, then that is the temp it should be when over volted and overclock.  So be warned, and go slow.  Try 4.2Ghz first then take it from there.  Anyone here with his CPU tell him what to put for voltage to OC.  Thanks and good luck my friend well get your OCed in no time.

No the 74c is while stress testing. I've come to the realization that 5GHz is just too much for my chip. 4.9GHz at 1.32V is fine, stays below 80C and that's AIDA64, with all the boxes checked. In games it's below 70. 4.9 is good enough, kind of disappointed I can't get 5, but I know it doesn't really matter. 5GHz just won't stay stable below 1.4, and I don't feel safe there, plus it's way too hot even with a 360mm AIO with the pump and fans set to full

yup...it ain't bad at all though don't worry 100 or 200mhz won't change anything, still a blazing fast chip.

Couple it with a powerful GPU and play modern titles on high-refresh rates...it's epic

I would drop it to 4.8ghz and 1.25v even.

Do you have fast RAM?

Speaking of which, you did win the silicon lottery, we don't know if this guy has won it or lost it.  4.8 at that voltage is a amazingly binned CPU.  Very nice nansuits very nice....

yes i agree...and i'm running my memory on XMP profile but the default was 1.35v and i run it at 1.20v so it looks like my memory is good as well...i could probably run 3200mz CL15 at 1.385v or something...easily. I keep all that for later...right now the platform is PLENTY for my needs...

Might get a 9900K in a year or two though

Latest BIOS is already installed.

 

i use a 240mm AIO with pump on quiet and fan speed bellow 1000RPM(push-pull) and at 1.2v my CPU runs at 68c tops while playing demanding online games like BF5 conquest...this is at 4.8ghz.. Stress testing it's like 72c full load at 4.8ghz and 81c at 5.0ghz 1.32v

Ram is at 3000MHz, that's how I got the system (got it whole on CL, couldn't pick my own parts really). Yeah 3200 would be nice but again, only 200MHz difference, like the CPU  I have an RTX 2070, 1080p144Hz monitor. Runs pretty smooth. In games CPU is under 65-70C. And I'm talking AC:Origins, or FC5 which actually do use 8-10 threads. I could drop to 4.8 @ 1.25 or so, but I don't have concerns about lifespan at 1.3-1.32.

Yeah I'm interested in a 9900K as well. Technically the 8700K is last gen now, so I'm not gonna throw money at delidding and liquid metal when there's newer chips out. I'll probably wait til 10th gen or Ryzen 3rd. At least the 360mm AIO will be useful for years!

i think at some point it might be worth it to buy a used 9900K from someone locally...and sell the 8700K.

but for now at least games runs flawlessly on 6c/12t OC Cofee Lake

Yeah, 8/16t is nice but the truth is a ton of gamers have 4/8 still so devs won't make it run like shit on those... Yet. I wonder how much better temps are with a soldered 9900k... Not having to delid is worth part of the price premium when you factor in delidding tools cost money, liquid metal does, plus voiding the warranty. Makes $500 look like a decent price imo

Yes and the Asus board ain't bad at all it will take a 9900K at 1.25v easily i'm sure,

 it barely even gets warm to the touch on the VRM heatsinks with my settings.

[Sgkpt]

@i_build_nanosuits Alright, I found the sweet spot now. Can do 4.9 at 1.30V, which actually ends up being 1.28V as measured by HWMonitor during stressing. Max package temp 85C, leveling off closer to 77-81C. Without FPU stress, that's 65-70C. In games I'd bet 65 max. I'll leave it here for good now. Is it weird that I can do 4.9 at 1.3 but 5.0 requires 1.4+? Seems like needing another .10 is a huge jump for just 100 MHz. Not that the 100 MHz matters, but just wondering if this is normal behavior because I'm learning and the more I know, the easier this will be for future chips. Thanks guys!

hello everyone, i have a little problem over here, i own a 8700k which is clock at 4.8 on a asroock extreme4

the cpu i just delid, i cannot run the cpu and run prime95 small ftt if te volt is at 1.385v under this mouse freeze every second or screen go black and come back , no graphic card install yet, these seem to be quite high temp if i do normal larger ftt i get 87celcius.

i run 32 gig of G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3600. i may have bend one pin that i did realign nothing crazy but still.

and i will repast the noctua chomomax bcuz i had a little paste but i had the same temp with more paste. is these temp are bad?

if i lower the Volt the pc freeze.

Can’t say if the cooling is bad, as we don’t know what cooler is being used. But yea it isn’t great. Prolly wouldn’t be overclocking it if I were you. Prolly put it at 4.5 and drop the voltage. Raise the load line a bit.
