(My Complete Build is in my Signature)

I am a *Complete Beginner* when it comes to CPU Overclocking. So as we move along to this (Every time you suggest I change something) if you could provide a short explanation of what that setting does I would greatly appreciate it). Doesn't have to be a thorough explanation (Unless it would require one for me to understand it at all).

I followed a high rated 200k+ view YouTube guide with someone that uses my exact Mobo / CPU for this overclock.

I am currently overclocked to 5.0Ghz and here are my current settings:

MCE Disabled (I know what this is)
AVX Offset – 3 (I know what this is)
Sync Cores/Ratio – 50 (I know what this is)
SVID DIsabled
Enter External Digi → Load-Line – Level 6 (Esp would like this explained)
Enter Internal CPU → Set Long/Short to Max
Core Cache Limit Max – Max
Min CPU Cache Ratio – 42 (Esp would like this explained)
Max CPU Cache Ratio – 42 (Esp would like this explained)
BCLK Adaptive Voltage – Always Disable (What is BCLK Adaptive Voltage?)
CPU Core/Cache Voltage – Manual
^Under This → Override – 1.350V

I ran AIDA64 (CPU, FPU, Cache) for 8 hours last night and when I woke up it said my maximum temperature during the 8 hours was 84C, and the average temperatures I stared at for 30min before I turned it off were about 75C (Highest I saw was 78, lowest 69)

I'm wondering if I can lower those temperatures by finding the lowest stable voltage at 5.0GHZ

Or wondering if I should go for 5.1GHZ and see if 1.35V is enough to handle that, and at what temperatures.

(I'm running a non-optimal fan setup at the moment, just ordered some more 3000RPM Noctua NF-A14s and I'm going to set them up optimally when I get them.)

^By the way, my fans are set at 3000RPM permanently. I don't care about noise *AT ALL*.

But once again, I'm a complete beginner, so not sure if I would have to change any of the other settings as well.

I would like to hit 5.1GHZ at least, or a stable 5.2GHZ (Max that I would want) if I didn't fail the silicon lottery.

Where should I go from here?

Hi testtube5 :)

I've reviewed your system specs and indeed a very nice high end system.

To reach your MAX Overclock will now depend on the CPU sample you have (Silicon Lottery)
You will probably need 1.375V on VCore for 5.1GHz and maybe 1.4V for 5.2GHz.
Your H115 should be able keep temps in check and 65-70C under load would be ideal.

LLC (Load Line Calibration) should be set to high to prevent voltage droop under load and to maintain stability. Also run in conjunction with CPU Current Capability set to 120%.

Overclocking the cache is not really necessary. You would get some mild performance improvement in tasks such as Video encoding and editing large files or rendering tasks. Min/Max CPU Cache ratio settings do exactly what they...

Min/Max CPU Cache ratio settings do exactly what they are labeled to do. At idle with Intel Speed Step/C-states enabled "Min. Ratio" will be the minimum cache ratio, under load it will step up to "Max ratio". I do not use Speed step nor Cstates when Overclocking.

BCLK Adaptive Voltage. Adaptive applies voltage in turbo frequencies....offset applies throughout the VID range..idle clocks to turbo clocks.

I think you have a good grasp of what you can do in Bios and to get your MAX oc will just require trial and error and stress testing.

Okay thank you, and what about max temperatures I should start to be afraid of?

I asked this question to other people but I didn't understand their answer because I didn't ask the question correctly.

They said that as long as I'm getting (for 8700k specifically) an average of 85C under load and random spikes to a max of 90C I should be okay.

But, what does this mean? Does this mean an average of 80-85C and a max of 90C after a 10 hour AIDA64 test? Or does this mean those temperatures average/max while gaming?

Basically, and additionally, what does "under load" mean, does that mean all cores at a constant 100%, or does that mean the CPU is just running heavily-ish (Gaming, etc)?
 
Max temps for longevity should not exceed 80C and the occasional spike to 90C would be OK. Constantly running the CPU at 90C would diminish the chip and that is not recoverable.
Your tjmax is around 100C and the CPU will start to throttle around 90C.
Also your VRM temps are important and would shut your MB down around 80C-82C to prevent damage.

You don't need prolonged testing in AIDA64, 20mins is long enough to establish stability.

Under Load is precisely what AIDA64 does on the various tests you can do. CPU, FPU and Cache at 100% on all cores.
I doubt you would experience stress levels higher during game play and general computer tasks.

I only want the CPU to last around 4 years tops. Is an occasional spike to 90C and a permanent average 85C 24/7 (well, waking 12 hours every day) okay for that?

Also, I know that this may be different for different CPUs, but, on average, how long would it take to damage the CPU running at a constant temperature of CPU; just out of curiosity?
 
Most Overclockers think in terms of, Oh, what is the best Cooling solution to achieve a stable system and keep temperatures below 75-80C at MAX OC under load.? Certainly Air cooling is not the solution.
You thought of that well and chose a H115.
I personally don't like temps going into the 80C+ and I can't give you a definite time frame that your CPU would last constantly running at higher than normal temperatures.

So, let me explain what I'm doing mainly (mainly when my computer is going to be under load). I'm multiboxing in a 20 year old game called Everquest. This is what my computer will be used for *AT LEAST* 90% of the time it is on. (Multiboxing the game requires as much CPU threads / power as possible, it uses virtually no GPU whatsoever no matter how many clients are up.)

Right now I have 12 clients up, OC'd to 5.0GHZ. My CPU is at around 35-40% load, and my temperatures are about 65-70 average. I built this computer with plans of running 18 to 24 clients at a time. I suspect 18 and 24 would bring me up to 65% and 90% load cap respectively. Though, I wouldn't know temperatures until I try it.

So, what you're saying is (Correct me if I'm wrong): My AIDA64 Temps - with CPU, FPU, and Cache at 100% - bringing me to 95C+ max or 90C average doesn't really matter for CPU longevity. All that matters is, while I'm multiboxing, I should stop overclocking (after I've optimized voltage and other) and declare that as my cap that I should keep once I start seeing average temperatures of around 80C, and occasional spikes to 90C or below.

Am I in the right ballpark there?
 
Do you mean by 12 clients that you have 12 copies of the game.? and you want to run all this on the ONE PC.?
I don't know a great deal about Multiboxing and it's usually against TOS. I do not approve of botting or multiboxing so your on your own there.
I personally think it's crazy what your trying to do however it's up to you.

Regarding your temperatures, As said before, If temps are constantly above 80C+ with an occasional spike to 90C it's not going to damage anything. If your running at 90C continuously then over time you would diminish the CPU and that is not recoverable. You have a much better than average PC, RESPECT IT.

Do not test AIDA64 CPU,FPU and Cache continuously for extended periods and I recommend to stop the test if temps exceed 80C.

Yes your in the ballpark but at the left side of the field lol.

Yes, by 12 clients I mean 12 copies of the game on 1 PC (I have 12 running as I'm typing this). My RL Friend does the same thing I do except with an i9 7980XE and runs 54 (A full raid) on one computer with tons of other stuff up as well...but, he's obviously a lot more wealthy than I am and just does it for fun.

Multiboxing is not against the ToS (In any game, unless the server is specified as a "true box" server." I'm doing this so I can kill targets that would normally require 20, 30, up to 54 people to kill, myself.

I am not "botting", which is certainly against any game's ToS, and would certainly get me banned within a month.

However, I'm supplementing my income doing this. When I get home from work and have nothing else to get done, if I feel like making 20 bucks, I can play for 4 or 5 hours, have some fun and make some money at the same time. (Which obviously is the reason I want to get as much as I possibly can out of my CPU). So, that certainly is against the ToS=P. But I have been doing it for 8 years and not a single account has been banned or even warned so /shrug...They turn a blind eye to it.

Thanks for all the help man, think I got all the info I wanted. =)

I can say the EQ1 going to be pretty easy to run on your system... I used to play that with an athlon single core back in the day, so an 8700k should run 12 instances of it without an issue.

So I played for a time on one of the new/old servers through daybreak. It was fun to get out there and play old school EQ. I did get a chuckle though that my 6700k had to work harder for EQ1 than a lot of modern games due to the fact that it was so CPU based and didn't even really use the GPU...

I do have a question, is it even fun to run so many characters... I used to run two back in the day just so I could solo regular mobs... I can see how playing 12 could be challenging since the game is pretty slow playing only one... When I came back to EQ for a time, I playing a tank and even MTing a group, I would pretty much watch netflix... :) Oh how game have changed...

It's a mixture of emotions. Fun when you finally down a target after attempting for 8 hours, a target that should've been done by 54 people (I box raids with other boxers on the FV server where the raid gear is tradable). Exciting at times, Infuriating at times (when you wipe on 10+ toons rezzing them is NOT fun), gearing them all is frustrating, keeping track of them can make your head spin. But what really does it for me is...

It's very challenging, exponentially more challenging the more toons you add. And I absolutely love a challenge. I'm super competitive. (I 18 boxed on 2 separate computers 3 years ago with 2 other 18 boxers (For a full raid of 54), no Macroquest, just ISBoxer, and the 3 of us were technically the 3rd best "guild" on the server as we had 7/8 of the current xpac raid targets on lockout farm) <-- It was absolutely the most frustrating thing in the world at times, but it is still to this day my greatest achievement(s) in my 10+ years of playing MMOs, even moreso than hitting Gladiator in WoW (Don't know if you've ever played WoW but Gladiator the title you receive for being in the top 0.5% of PvPers in the US (Or EU)), and easily the funnest time I've ever had in my gaming career - at times.
