How much performance do I gain from overclocking a default clock 7700K

[Ellie]

Lets assume I won silicone lottery and it goes up to 5,2, how much more performance will it gain in games which are cpu-reliant ?

It really depends on the game. In Far Cry 5 the difference will likely be minimal.

yep depends on the game. TW:WH2 gave me only an improve from 35fps up to 40 fps... World of Tanks gave me an improve from 110 fps to 160fps.

PS: the CPU OC gain is in general betetr then a GPU OC. Also it depends much on tempretures and speakign of that your airflow. Next importance is the settings and optimization of your system. Its much more then just changing the multiplier from 42 to 52.

Because it's not that demanding of a game. It's a AAA game, the dev will make sure it runs playable on as many machines as possible. But you can always just OC and see if it make big enough of a difference for you.

could you give me a good source of how I overclock in the BIOS ? Like how I have to set voltage and the multiplier

Look up some Youtube videos. Google what people recommend as the highest voltage you should run your CPU at 24/7 (It's v1.30 I think).

Then if you are able to keep your CPU cool at those voltages see how high you can push the clock before it starts running unstable.

Test the OC with Prime95 and/or AIDA64. If your games/Windows start crashing or your PC starts freezing etc.. after the OC it's not running stable, decrease the clocks or increase the voltage until it does run stable.

thank you

What gpu do you have? If high end at 1080p cpu overclock will make a bigger difference generally to test cpu performance you turn the settings down and set 1080p as yhe load wont be on the gpu anymore as you increase load you become more gpu dependent

https://youtu.be/qCYOaO6wm6s

btw heres the difference at 4k being completely gpu at 4.5 stock and 5.1 ghz its not done rendering because i just did it quick but there you go having a better gpu would should increased performance over mine but overclocking would not add 40 fps when you are still gpu bound. i can show you 1080p performance gains from overclocking if youd like

I do have the GTX 1080

Then at 1080p you will most likely see gains from cou overclocking id start at 4.7 ghz 1.25v and see if you are stable if that works go up to 4.8 and so on until you crash then up the voltage slowly

What Motherboard do you have?

But generally speaking:
- you should not cross 1.4V (even tho I crossed it but I upgrade my CPU's always within 9-12 month so I dont care about much shorter live span).
- Unless your CPU is delidded the limitation will not be the Voltage but heat.
- Do not touch the bus speed

As higher clockrates decrease stability you have options to improve stability:
-lower uncore settings (should be ~4 below the clock multiplier, e.g. 52 CPU Clock => 48 uncore)
-set AVX Offset (raise the AVX offset from 0 to 1-5, higher offset means higher stability but lower clock on those special and rare AVX instructions)
-increase voltage

Thanks a bunch, I do have the MSI Z270 Gaming Pro Carbon

Sorry Jef, the difference between a 1080 and a 1080ti is huge, even overclocked Vs stock a 1080 doesn't really come close, add to that your 1080 has a somewhat low overclock, with good ones hitting 2100-2200, hell, my 1080ti's that clock lower than 1080's hit 2088MHz.

Yes 4k us going limited, but if you have a powerful GPU the CPU can still make substantial gains, most of the time it just isn't as noticeable as at lower resolutions.

The difference between a 1080 and ti does not show 40fps gains at 4k period show me literally any proof otherwise he said he was getting 40-60 fps at 4k overclocking is cpu and ram got him to 80-100fps if you are gpu limited cpu overclocks do not gain that kind of fps never have never will

[Monk]

Pubg isn't as demanding as it once was (they really dumbed down draw distances), and the limiting factor of the GPU at 4k is limited somewhat with the far more powerful 1080ti, plus,tacoshy did say he wasn't at max settings.
He was also commenting on stock Vs massively overclocked, not 4.5OC to 5.2.

The 7700k turbo boost is 4.5 stock so that is stock settings vs a 5.1 overclock as i posted if you are gpu bound at 4k overclocking your cpu will not add 20-40fps im still waiting on his vid by all means prove me wrong i posted mine. If he was only getting 40-60fps his gpu was maxed if it wasnt he wouldve been getting more and the cpu overclock wouldnt have made any difference just turning off vsync would have stopped the gpu being limited. This isnt new and has been known for how long cpu overclocks make sub 5fps gains at 4k as yhe limit is the gpu

Just so you know op before the cpu overclock made no difference i can clock my ram 200mhz higher and leave the timings but that would be under 5fps boost i can also clock my cpu at 5.1 if that would make everyone happy yo have them within 2% of eachother

and a GPU which is 30-35% stronger. The entire Game that sits in the RAM and data doesnt have to be laoded from the drive as it sits completly in the RAM.... and for DDR4 a timing difference of 3 is a huge difference at faster clock.

But to make you happy I will make a video later.

Did you install PUBG in the RAM instead of HDD SSD?

Not directly I always move the games I want to play to the RAM disc. For PUBG it isnt even hard as the game only takes 14GB space... everybody with 32GB RAM+ can do this.

Jeff the the boost clock of the 7700k is a single core to 4.5, the rest remain at 4.2, so an overclock to 4.5 is a considerable increase over stock, this is why just overclocking manually so all cores run at the boost clock is very useful, and why the MCE on some boards make things like the 8400 such a good chip.

Edit.
While I don't know if what tacoshy is claiming us right or not, and if it is it may be the odd spike hitting the upper limits, but, your reasons for it not working is flawed, your system isn't comparable to his, so your results don't show anything, your CPU, GPU and ram are all slower.
