My core frequencies are fluctuating on load from an overclock
My Specs -
CPU - I7-9700k stock
MOBO - Z390 A pro
RAM - 32 vengeance clocked to 3000
GPU MSI - 2070S
PSU - 600w Evga White plus
AOI - Arctic Freezer 2 240

In short - My core frequencies are fluctuating on load from an OC. I do not know why.

Longer version - I have a i7 9700k which I have Overlocked to 4.9 over its stock of 4.6 many times.

I had to remove the OC as my case and cooler could not deal with the CPU heat. I just got a new case and got a AOI so I can OC.

I OC the CPU to 4.9 using the default option to do that on the MOBO - I'm very used to doing it.

I OC to 4.9 and then once I was testing while gaming, using MSI afterburner, I can see my core frequency fluctuating on load, dropping back down to 4.6 then it would go back up to 4.9 and it just keeps on doing until its idle then its back up to 4.9.

I used Hwinfo64 and CPU z confirming the drops.

My Temps are stable and under 80c at all times - Mostly 60s to 70s tops.

I have tried manually OC to 4.9 and putting it on fixed and set my own votage to 1.25.

I can't work out whats going on, I don't see anything about overclocked cores dropping down to stock on load only.

You have it on 4,9 at idle?

And the voltage constantly at 1,25?

You waste a lot of energy for 0,3 more.

4.9 is faster than 4.6.. It was stable for a while but did crash with some time. But even still the core was fixed to 4.9 .. Only stayed fixed when idling

My suggestion is to quit messing with it. Put it all on default settings and leave it alone. What do you need it to be running that fast for? There could be but I don't think there's many games out there that require over 3.2gHz.

When you tweak hardware, mess with overclocking etc, you're asking for trouble. It's the same concept as the strange people who get a 4cyl engine and ridiculously modify it with superchargers and nitrous = the engine doesn't last very long. They don't last very long because it's not built to be run that way. Neither is your processor.
Just because you can doesn't mean you should.

If you mess with overclocking and go way too far with it, like you're doing, all you're really doing is significantly shortening the life span of your computer.

Of course it's not going to be stable. You're pushing it too much.

Disable P States in BIOS and make sure Windows power plan is set to high performance.

4.9 is your CPU's turbo boost speed anyway, if you set everything to default you wouldn't see much difference in performance

It could be a whole number of things causing it to fluctuate.

You seem to be barking up the tree of fiddling with settings, when it simply could be an airflow thing or something more physical. The fact you've changed case and other bits can mean it is getting ENOUGH airflow, just not efficiently or in the correct way - like air pockets heating up or pressure pockets.

But I'm in agreement with everyone else here, for the miniscule amount of extra youre going to get, it ain't worth messing around with especailly as it'll shorten the life of it all as well.

So is it really worth getting a tiny scrap of improvement, but last less time?And that's even assuming you sort this out.

4.9 is faster than 4.6.
I do some math:
0,3 of 4,6 is less than 1/16.

If we assume this is equal to gain, even if you have 160 fps, you gain 10 fps more.
At the cost of no idle, no reduced energy consumption.
Note, this is the best outcome assume.

Depending on where you live, you could get a better cpu or grafic card instead for the same money you waste through the chimney.

Well need and want are two separate things. Maybe you only need the minimally required entry level hardware at stock speeds. Other people want something else, and they're allowed to shoot for the moon if that's what the want.

No. You're asking for trouble if you're doing it recklessly and solely because everyone else is but don't understand what you're doing and don't take any care. Otherwise trying to make it sound scary or dangerous when people have been doing it in droves for decades is textbook hyperbole.

Well while I do like analogies I don't think your conclusions that overclocked hardware doesn't last very long is based in fact. The more reckless you are I suppose there's some risk, or bad luck. You seem to attribute quite a bit of magic to the stock speeds as being the the optimum speed for any particular chip. Plenty of CPU's can run several hundred mhz beyond their stock speeds quite comfortably and safely.

I would agree. I'm not a huge overclocking proponent personally. It's fine. But some people are so sold on the idea they see it as almost an automatic step. But it also doesn't mean you should not overclock either. It's just a preference.

Probably not. There's lots of safety features on hardware. Also there's not really a good way to measure the lifespan of a particular CPU. And nor is there really a way to estimate how particular usage affects that lifespan with any accuracy. If you're fooling around with OCing unless you somehow actually damage the CPU so that it no longer functions at stock speeds even, you're only guessing and assuming at damage accruing. It's more imagination than anything. Otherwise we'd have better ways to quantify that damage that don't rely on the vaguest warnings possible.

Originally posted by Jack Schitt:

It's plausible. After all there's no guarantee that a particular CPU will overclock to X speeds because a lot of other people have managed it. Some people win the silicon lottery, some people lose it. 4.9 might be too high for that particular CPU.

OP would be wise to start from stock and work their way up. Once they hit a speed that's no longer stable and they can't seem to make it stable with fairly easily then the last stable speed might just be it, whether that's 4.8ghz or less... regardless of what other CPU's have done or what their expectations are. Maybe better luck next time on the silicon lottery. But alternatively there might be a configuration that works at 4.9. Just a matter of how much effort they're willing to put in to get an arbitrary incremental improvement.

What I said is not at all hyperbole.

I have been in the computer field professionally since the early 1980s. I have never once seen an overclocked computer last more than a few months, maybe a year for people who got lucky. I personally have computer equipment that's over 20 years old and still running and it's still running because I've never messed with it trying to tweak it and make it run beyond how it was designed to run. The router I use for my home network was purchased in 1994 and is still the main router for an 8 computer, 4 printer system in my home. I have never done anything to it other than take it out of the box, plug it in, turn it on, and set it up.
I think it might be safe to assume my router is older than most of you.

I'm still running a computer I built in 2007 I bought all of the best of the best and fastest stuff you could get at the time. Never even once overclocked or messed with hardware settings. Not even once. It's going on 14 years old now and it's still within the top 10 benchmarks.

When I bought all of it I bought 3 of them. I have spares, that I haven't needed in 13 years, and I sold the third set to a friend who overclocked the CPU, Motherboard, Video Card, end tweaked the memory.
It was a boat anchor 6 months later after he got it.
And it's not because he tweaked it recklessly. He killed it simply because he tweaked it. Like the OP here he had absolutely no real good reason (because we can is not a good reason) to.

I can but won't share thousands of other experiences I've seen with other friends who just have to mess with clocking and tweaks and this and that extra utility program(s) that don't do anything the operating system does it self.

If you want faster stuff, buy the faster stuff so it lasts.

You should not run a router out of the box. By setting up, you likely mean change all passwords and keys as well. just to name it.

Things can break on their own, though.

People, even "professional" (cough) installers from large internet company's plug'm in, turn'm on, and leave after checking that they're connected by going to a few websites.

Default network security keys are impossible for someone to guess and they can't be gotten without some pretty advanced know-how or being wired to the router.

They almost never go in to the control panel at all. Changing the network name and anything else is optional. It does not have to be done.

That is fact. Look at your own wi-fi list of available connections. There's probably many of your neighbors who haven't renamed their network, just left it whatever it was out of the box whether they installed it themselves or let a "tech" from the company do it for them.

It's not "all" hyperbole. But it's clear you have some strong opinions that are somewhat at opposition with some pretty common knowledge and not all your claims align with reality. It's pretty hard to take you seriously when there's a whole industry built around overclocking and not a very large pile of dead hardware to point at.

Well that doesn't insulate you from being mistaken, making mistakes, overestimating your abilities or having bad luck. I know a lot of old guy IT people who don't really keep up and so their experience and expertise ends up being pretty limited.

I've got over twenty years experience myself and work in software development professionally. So... not sure what to tell you. We're talking about a fairly accessible thing when it comes to overclocking in the 21st century, not something you need decades of IT experience in at any rate.

No. The average age of a gamer is in their 30's now, fyi. Maybe you like the idea of being the oldest wisest guy in the room. Making arguments of authority don't matter when they're in clear opposition to the experiences of a majority. It just means you're not an expert outside of whatever niches you operate in.

Well not sure what that last sentence means but it seems like you're very proud of something, so cheers. But it would have to be a pretty dead benchmark for your 13 year old hardware to appear competitive to anything from this decade...

Correlation doesn't necessarily equal causation. Whether or not your friend had bad luck or managed to kill his hardware doesn't project onto the rest of the world. Or nullify everyone else's experiences.

You're aware of confirmation bias right? How do you respond to the avalanche of anecdotes where people have professional experience, lots of friends, or positive experience overclocking all sorts of hardware and have it run as long as anything else?

I mean I've got a 13 year old Core 2 Q6600 that I OC'd 600mhz and ran it for years, I can go turn it on right now. It's not amazing, exceptional, or unique. Not even close. It's about as mundane a pair of socks...

You can read default logins for routers in the internet.

There are also cases where a producer patented the function how to create a pin by the (ssid) which was the unique number of the router.
That alone is stupid, but making it a patent...... lol

It wont hurt to change all default things. But it can save you.

Additionally network keys can be brute forced offline. So you better make them long.

Blocked and TLDNR. You are very biased and stuck in your own bubble world of your own opinions. What I shared IS reality because I was there and experienced it.
A person trying to overclock a computer DOES need experience and knowledge of what they're doing. It's not something someone who just got a computer, never worked on one before, should be doing.

The fact that the OP wrote the title the way they did proves their inexperience and ignorance on the subject. So their best bet, if they want their computer to last more than a few weeks, is to set it all back to default and leave it alone. If they want a faster computer - buy a faster computer.
They're fixing something that isn't broken, therefore they're going to end up breaking it.

Most of us here are trying to influence them in to having a computer that lasts.
Your router is from 1994?
What encryption does it use? The good one came a decade later.

It is fascinating you criticizing my response when you claim you didn't read it. Kinda makes your response worthless. I'm confident you've already demonstrated you're not a source to rely on as far as this subject goes, so I'm satisfied with that.
