i7 9700KF and RTX 2080 Super Dual OC speeds for HP Reverb

[Tonester]

Hi all...just got my new PC...running i7 9700KF. I see its standard speed is 3.6 and turbo speed is 4.9....is there something I have to do to enable this or will it just ramp up to that speed when I need it....I have just purchased a HP Reverb you see and I know I need fast core speed for it....excuse me if this is a no brainer question...I don't know that much about PCs in this regard. Also to run the reverb at good frames do I need to overclock my RTX 2080 Dual Super OC or will it be fine as it is?

Turbo will go up to 4.9 but it will only be on a couple of cores assuming it is similar to how the 9900k works.

Ideally you will want to maintain a consistent overclock on all 8 cores, with no AVX offset,  as IL-2 will jump around on cores it uses. So if you are running IL-2 at stock speed, then it will jump around from running at say 4.9 to 3.6 and so on.

If you have a decent cooler overclocking should not be any problem, you should be able to get around 5 GHz on all 8 cores, of course depending on the good ole silicon lottery and your cooler.

 

I would start low, like 4.7 or 4.8 on all 8 cores on default core voltage, and see how it does. Personally I use Intel Extreme Tuning Utility stress test to test each change for about 30 minutes as I make adjustments, keeping an eye on individual core temps. I use Core Temp for this. During this process as I test each slight bump in speed, I will start to get errors and then I bump up the vcore slightly and test again.  Once I get it about where I want it and am happy with temps, I will then tests it for a good hour or so to insure stability.

 

As far as GPU, every little bit helps, but really CPU is where most of the focus should be. I have my 9900k overclocked to 5.2 GHz on all 8 cores, but I also have a 360 mm AIO cooler and even with that it can certainly get somewhat warm. I also have my 2080 Ti overclocked to 2.1 GHz.

On a very warm day I will often bump it back down to 5.1 GHz   on all 8 cores just  along with lowering vcore a little  to give some more headroom on core temps. Not much difference for me in performance in IL-2 between the two.

thanx dburne...I am running a Corsair Hydro H100x AIO cooler...I must admit I don’t know if that is good though lol

Highlighted the most important aspect (everything is exactly right, but I want to stress this!). 

 

You need to disable the AVX offset or your 4.9GHz boost (or any overclock!) is actually running at ~4.4GHz (what is the standard offset, 5?) as soon as you start IL-2 in VR.

It will likely be ok, just keep an eye on those core temps as you do this.

There will be an option in your PC's BIOS.

[SCG_Fenris_Wolf]

You need to do the research on that yourself and go by your motherboard's manual / manufacturer specifically. It's not the same layout for every MB out there so we cannot help you there.

 

Truth be told: It's mandatory to get done to achieve decent performance in IL-2, so you better not skip it and get to it. Good luck ?

It's definitely worth Googling an overclocking guide for your motherboard. There are usually loads of settings, and in particular the "auto" voltage setting on a lot of motherboards can put more voltage than really needed through the chip, making it hotter than it would be if you manually controlled the voltage.

[SCG_Fenris_Wolf]

Very true what @Alonzo said. You need to lower that LLC (load line calibration) to at least 2 usually, to avoid VRM (voltage regulator module) temp spikes. Hope your MB has some good heat dissipation on it, and a proper airflow over it. It was a problem with mine in the past.

Well finally got my new PC and HP Reverb set up. Been flying a few missions and WOW....only downside is now I will never be able to fly CLOD again...well at least not until they implement VR which will probably be never based on how long it’s taken TF 5.0 to come out...was so easy to set up too...wish it was as easy to setup in xplane, p3d4 and dcs...oh well cant have everything....lovin VR...incredible

[WheelwrightPL]

Are you running extreme shadows and high clouds in career mode ? Sadly I find that my system cannot handle that with Hp Reverb (I have 2800 Ti and i3-8350 CPU overclocked to 4.6). As a matter of fact all I can run is most simple QMB missions and even then I have to live with jarring reprojection-induced image distortions and "double-vision" enemy planes if they are zooming by even remotely fast. Do you have a better experience with above image settings in career mode ?

[chiliwili69]

Even if you are not an expert in PCs it is convenient to spend some time studying the overclocking guides since you will benefit from this free increased performance all your life.

 

Just 3 years ago, I never did OC. I thought is was something dangerous and only for gurus. This is absolutely not true. Now I do that everytime I play IL-2 VR.

Just invest 1 or 2 days in learn and try the steps, it is really worth.

 

This is my quick guide for OC:

 

Also,  you should realize that the 9900KF has 8 physical cores. 

After achieveing your max OC with 8 cores you can experiment in going further by disabling 2 or even 4 cores. And see if you get less heat, so more OC, so better performance.

I think IL-2VR in a 9900K or KF os KS will run better with just four cores at 5.4GHZ than 8 cores at 5.2GHz.

 

To measure the performance you can use this recorded track:

i3-8350 CPU overclocked

 

I assume you refers to i3-8350K. Some people reported test (with old Balapan test) at 4.9GHz.

 

I think this chip can overclock more if you have a good cooling solution and right voltage. Have you tried to run the remagen test? (Just to know how your CPU performs at monitor with different freqs)

[DD_Arthur]

Wow! People are getting 5.4GHz now?  Man, I’m still livin’ in the VR Bronze Age.....?.

Not likely unless on some very elaborate water cooling. Or they don't mind a chip frying in a few months.

Each core is still going to have the heat from the core voltage regardless.

Also keep in mind IL-2 is not the only program running, there are many Windows processors and others.

Windows does a pretty good job spreading some of that out to other cores, so having more cores is not a bad thing.

I’m running everything pretty much maxed out and it’s amazing!...I haven’t OC my CPU as yet....if I start noticing stuttering I will look into it

Not exactly like that.

 

On the office we acquired a 9900K more than 1 year ago and it was using air cooling (Noctua NH-D15S). We were able to achieve 5.1 with 8 cores, 5.2 with 4 cores and 5.3 with 2 cores.

It has been running all time at 5.3 doing intensive single-core simulations applications.

It is a fact that with less cores you generate less heat and  therefore you can achieve a higher overclock.

 

Anyone with an 8 cores CPU can test himself. Just disable 2 or 4 cores maintaining the same frequency and you will not see any performance degradation in IL-2 VR, but your temps will improve.

I can not do that since my CPU has only 4 cores, but if you have time and curiosity these days of confinement, you can test it. Otherwise just enjoy and live happy consuming some extra watts.  ?

No

LOL, not much concerned about watts here, so no. 

I do enjoy and I do live quite happily.

I got direct die cooling with liquid metal for my i7-9700K. Now stable at 5Ghz for all cores with AVX 0 offset. Temp never go above 80C under 1.35V in stress test.

 

The CPU core temp could easily reach 98C before.

How is your experience so far ? I hope still enjoyable. Can you run IL2 career mode on ultra shadows and high clouds without turning on re-projection ? (maybe I am spoiled but I can't compromise on those settings).

Currently I am on the fence of buying the processor you have: Intel i7 9700KF, to fix lacklustre performance I have with my overclocked I3-8350k, that's why I am so interested in your feedback.

[Tonester]

@WheelwrightPL - Really good so far. I don’t use SP at all so can’t answer your question about career mode. Online I have had 0 stutters thus far and I’m generally in combat box when it is completely full. As for reproduction I haven’t turned it on because I don’t know how...lol...I’m old and not real computer savvy

Come on, Fenris, you have der8auer http://der8auer.com/ryzen-3000-oc-bracket/

What I still find interesting is this type of direct die water cooling

I use ThrottleStop to overclock and undervolt my 8700k.

 

Running stable at 5.0Ghz on all cores and 30 Mv undervolt. One core clocked to 5.1 Ghz to allow for games that still rely on one or two cores.

 

I undervolt to keep CPU running below 1.4 v. CPU sits at 1.2 - 1.3 usually.

 

CPU runs at 50 - 65C on stock Dell watercooling when in use when 20C ambient.

Games that use one or two cores, will vary the cores being used during the session. It won't always be on the same core/cores.

[Gomoto]

Instead of overclocking my  cpu I downclock my brain, I am now used to 45 FPS ?

 

But I can not stand anything less than 200% rendering anymore ?

 

(By the way I tune my 1080ti quite a bit until the 3080 arrives on the market. The only reason I do not overclock my 3600X, it does not change the VR performance.) 

 

 

One more reason for 45 FPS VR, that way my CPU and GPU are a perfect match. I have lots of headroom for CPU intense options when opting for 45 FPS.

Perhaps it also helps I have a 10 FPS simming past 30 years ago.

I'm going to try the direct die cooling.  I'm at 5.1 now, I'd love to hit 5.3 steady.
