I'm wondering how much more fps can be improved even if I clock it to 5.1 over it's current 4.7.

Depends what you're aiming for.  400Mhz is approx 8% increase, so do you need that 8% FPS uplift to reach a stable target frametime, or give yourself a bit more headroom in comes scenarios? If yes, it's worth it, if not, it might not be....

Let's say we are VSYNCing to 30Hz and seeing 26fps in a complex area in the sim but are hoping for 30fps solid. 5.1 / 4.7 = 1.085 so as you say you might have around 8% extra core speed and that 8% at 26fps so let's say 26 x 1.085 = 28.2. It's not exact but doesn't get you to 30fps and in any case the % lift in core MHz does not equate to % lift in fps exactly either. The 8% headroom may come in handy to save on some amount of stutter in some places. As Ray said he reduces a certain setting or two and gets the same improvement anyway, not quite as much eye candy or amount of AI traffic maybe. Although definitely, the overclock may be worth the time investment for fine tuning to see what can be done exactly, but if Ray's settings can be lived with then maybe he need not worry about extracting every last drop of performance for extra heat in a system that works reliably and quite sweetly at the moment.

No matter how fast the fans spin it'll never get off the ground, or perhaps if wings are attached... lol

I use FSUIPC to reduce Ai where necessary to keep fps at 30. It works reasonably well but at busier 3rd party ones it drops it to the minimum I want (50) but still fps cannot reach 30. But 25 is hardly difficult to land with. I think after a while you just get accustomed to thinking if it's not 30 it's bad. In reality down to 20 is probably okay but even at EGLL it stays around 25 on current settings. Probably not ...

I have used MSI Afterburner but in combination with RTSS for on-screen monitoring of CPU, GPU etc.

I don't have it running with other programs. I only use it to test and set overclocking. I thought RTSS was related to that other package, RivaTuner,

The i7-8086K is different in that core 0 is turbo-boosted over the remaining cores and how that would be handled with MSI I'm unsure.

Afterburner [ No! AI Suite 3!!!] can set each core separately, or all together. I don't think this is anything to do with the BIOS turbo boosting modes. I just have all cores running at 5.5Ghz (up from the 'normal' 4.5).

Instead of thinking in terms of fps think more it terms of smoothness -- less stutter because of extra headroom, or more capacity for higher settings. And if you can get the other cores up as well, the background operations like scenery and object loading  could be faster.

The 8086K was said to be one of the most overclockable processors at time of release. I'm rather surprised Chillblast didn't do that for you. All three of the systems I bought through Palicomp in Crewe were expertly overclocked really well. (I'm still using the 3rd one -- for MSFS on my VFR cockpit).

But HT off and no messing with any core affinity settings.

I just need a bit of a rest and some flying.

I've been doing almost zero flying. When it was hot I was feeling really ill (hot humid conditions really don't suit us older folks), and very tired from getting precious little sleep. And even now, by the time I'm back from dog-walking my back is so bad I don't feel like setting up the cockpit for a flight.

But I have been keeping it all up to date -- latest AIRACs, latest version of ProSim, ASP3D, etc.

I think I really do need a proper holiday, on steam trains in Eastern Europe and trying new breweries. I'm sure that would perk me up! 😉

It is. Seems Afterburner is multi-purpose.

I'm scared to death of melting the CPU because of inexperience. I'll have a look at the interface and see how much it scares me.

Overall the sim is very smooth. I think restricting fps to 30 with VSync helps a lot. Yes, it's disappointing Chillblast didn't push it more especially when the service was a chargeable extra. I might look at Palicomp next time.

I did no flying last week with the high temps. Just keeping the rabble in order here. 😁

I'm sure a good holiday would help you Pete. Pretty dreadful for the last 16 months but things are looking up nicely now. I'm sure you'll be able to get away in the autumn when the weather is still decent on the continent.

Don't be, they all incorporate thermal protection so the CPU will throttle before you create a mini Chernobyl.  Worst case scenario is you just have to back down the o/c until everything functions without problem. I have a surplus 8700k here which I've had running at 5.0Ghz happily before and I'll donate to you foc if anything you do breaks yours 👍

Ray, overclocking is made much easier by programs like MSI Afterburner without venturing into the BIOS. 

Pete, Sorry if I am dumb but on my MSI Afterburner, there is no mention of anything other than GPU overclocking. v4.6.3.16053.

Is there a hidden setting, or do I need the Optician again?

Having looked at it I’ve come to the same conclusion. A CPU fan control option seems to be it for the CPU side of things.

Theres no option for a paid version either so it’s a bit confusing.

Aaaarrrgghhh! You are right! It isn't Afterburner I meant, it was AI Suite 3 !!! Oops! 

Sorry, Ray ... my poor old brain is having memory problems.

Don’t worry Pete. I’ll check the software that came with my Chillblast.

I'm now not sure whether AI Suite3 works with non-Asus mobos -- but as you are using Asus it'll be fine with your mobo.

@Pete Dowson

I have a Asus MB.

I do not know what i have to change for a good overclocking with AI Suite3.

I have  a I7 9700K

Must i  select al cores .

Since this has morphed into an overclocking discussion, I've moved the thread to the hardware forum.

One thing about AI overclocking is that it often sets the voltages WAY too high...some would argue dangerously high for long-term use.  It's easy...but the methodology used is pretty much "brute force".

Unless you're trying to go to extremes to get max performance, it's generally pretty easy to get modern CPUs (equipped with appropriately solid cooling) to a good all-core overclock without a lot of fuss.  Lots of decent guides on the interwebs on how to do that.  I don't think it took me more than half an hour to get my 8086K (now used as a FPS and driving game machine) to 5.2 GHz, and another hour to fine-tune it to 5.3.  The 8086K was especially easy because it's a top shelf selectively-binned IC.  The long pole in the tent is the 8-12 hours of post-overclock testing to make sure the O/C is stable.

Frank what is your MB ?, i have a 9700K and simply OC in the UEFI ( bios) of my Maximus Hero XI , by selecting XMP1 and all cores to 5.0

I ran the automatic mode first -- that keeps winding things up till it causes a crash or other instability, then on re-boot reverts to one step lower. then for safety I go one lower again.

Note that although I'm using 4500 MHz memory (by spec) I had to keep its clock lower than that for stability. I think it defaulted to 3600 MHz anyway, but Rob wound it up in the BIOS (not possible to do in AI Suite 3). In the end is was a choice between 5.3GHz cores and 4000 MHz memory, or 5.5GHz cores and 3900 MHz memory. The latter won performance-wise.
