Hey guys i am wanting to purchsde a 7700k with a new mobo abd ram

Thou wanting to keep my 2 x titans sc

Will they bottleneck?

What mobo and ram do you guys recommend?

 

Cheers

I would take an ASUS PRIME Z270-A and some DDR4 RAM (G.Skill, Corsair Vengeance, not necessarily high speed ram). This is pretty standard config we do with that CPU.

 

Don't forget you will need a cooler for the 7700k - better be a liquid one if you plan to overclock (I assume is the case since it's flight sim)

 

Also, what is your CPU right now? I ask because depending on that maybe you won't get a big difference with the upgrade.

hi 

I have currently ai74790k at 4.4ghz

Asus vi extreme mobo

And 16gb ram redline mushkin

 

Will my gpus bottleneck tho?

I may be wrong, so others please chime in, but I don't think there is a significant performance increase from a 4790K to a 7700K?

Just my understanding, and apologies if I'm wrong, but double check, as it will save you some money upgrading!

And why should the GPUs be the bottleneck? Especially in P3D? :-)

Hi everyone,

I am running 6700k@4.5Ghz, people say 7700k can overclock to 5Ghz, that is 500Mhz difference and I'm still curious if it will make any difference in P3D. I tested 4Ghz and 4.5Ghz with my CPU and it does make a difference.

The graphic card (even GTX 1080) sometimes run P3D at 100% but still have poor performance, I think it is because the simulator is poorly optimized. Even running at 100% it does not use all the resources the graphic card provides. And for P3D almost always CPU is the bottleneck not the GPU.

I've got both a 4790K and 6700K running, and the biggest difference in my opinion is the ability to up the memory speed in my case to 3400 MHz.  Memory speed matters, but for the cost maybe you should simply add a liquid cooler to your 4790K.  You should get 4.7GHz on that 4790K with liquid.

The only reason I have the 6700K (OC 4.7GHz) is because I wanted a second computer dedicated to flight simulation.  Stuff like charts, flight planning and my home office are on the 4790K.  I wouldn't go to from a 6700K to a 7700K, and not sure I would have gotten the 6700K had I not wanted a second computer.

I've never seen my 980Ti work any harder than 40% of GPU... not sure where a 100% GPU loading is coming from. Interesting.

What do you use for measuring the GPU? I use nvidiainspector it has a "GPU load" section. If this is the correct one then I get 99% or 100% every once in a while especially when loading heavy clouds it goes 99-100% all the time.

Using Process Explorer.  I dropped using NI about a year or more ago or somewhere around P3Dv3.3 and especially now with a 4K display I don't need much in the way of graphics tweaks.  I have seen GPU loading shoot up and frame rates plummet when there is a solid overcast or even undercast, and I learned that using a 20 fps frame rate lock fixed that without any impact on the smoothness of animation.  I suspect the increased GPU value has to do with frame rate locking.

Not true. The NH-D15 and my favourite the NH-D15S cools beautifully and is very quiet. In fact it's only about  4 - 6 degrees warmer than the mighty (and noisy) Kraken X61. And 4 - 6 degrees amounts to a minuscule increase in frame rate as a result of the minor additional overclock. And of course zero chance of leaks and no pump to become noisy or fail.

If the aesthetics of a big tower cooler aren't considered favourable, and there's limited room in the enclosure, or one gravitates that way as a result of personal choice... by all means AIO.

As long as your rig is fairly well balanced, overclocking tends to be linear. You get the same percentage increase in frame rate as frequency increase. Or more or less. Doesn't apply to games though (except those that are very CPU oriented) as most games are GPU biased.

Thank you for your reply guys

Might just overclock my cpu a little

My 4k ips hdr tv 49 inch arrives tomorrow 

Hoping mu gpus will be ok for that

 

Cheers

Depends on where you look (and whether the CPU is at idle or full load). Here: https://www.guru3d.com/articles-pages/noctua-nh-d15s-cpu-cooler-review,8.html they show the NH-D15S to be 10 deg C warmer than Corsair H110i GT under load. That's not to say that the NH-D15S isn't a great cooler, will almost certainly be quieter than an AIO and, in most cases, will control the temps well enough for the majority of users. It's probably only with extreme overclocks that the extra 10 deg might be significant. But, as you say, for most of us it boils down to personal choice.

Yep.

I was referring to full load of course. In addition to cooler capability it depends on the degree of overclock. 

It also depends on the fans. Not so much the H110i, as it is pretty quiet, but as you know many AIO's have higher RPM fans. Thus, with the same fans the gap closes. Important of course to look at delta temp too, as obviously ambient temp varies.

To get a true picture one review, one sample isn't enough, we would have to look at many, otherwise we're just cherry picking. 

4 degrees away from the Kraken here...

 http://www.relaxedtech.com/reviews/noctua/nh-d15-versus-closed-loop-liquid-coolers/2

0 degrees different here.  With 3770K and the H110. The "i" variant is improved of course.

http://www.relaxedtech.com/reviews/noctua/nh-d15-versus-closed-loop-liquid-coolers/2

8 degrees  here, but with the Krakens fans in deafening mode.

http://www.tomshardware.co.uk/zalman-reserator-3-max-dual-nzxt-kraken-x61-noctua-nh-d15,review-33085-5.html

2 degrees away from the H110 here. and gain, not the "i" or the "GT". 

https://www.overclock3d.net/reviews/cases_cooling/noctua_nh-d15_review/6

So yes, review temps vary, lots of variables, but add another 5 or 6 to that list and we'll get a better picture.

You are correct. Not much of a difference.. If any, it's very little.  So small that most will never notice.

Water Cooler is much better! Much Better!

Since our "game" is so poorly designed, there is little no improvement  between 4.7Ghz and 5.2Ghz. You might see a bit of a difference if you test it on a vanilla copy. But, will anyone fly on an out-of-the box P3D and no add-ons?  Very likely not.

Honestly it's not fps we're worried about it's OOM's.  Hopefully P3D x64 and FSW will change that. 

Ot you could try out XP11, we don't worry about those OOM's hehe.

No it's not. Did you not read the reviews I posted? Not unless you regard the D15's 4 degrees warmer than the Kraken, under load, as "much". Most wouldn't.

The odd review has it further away, but you need to consider something... I own the cooler!  Currently 6700K  4.6 GHz at 74 degrees in RealBench. Utterly quiet.

And then when we install the same fans on the D15 and the best AIO's.... the gap is even smaller.

Big air, namely the NH-D15 and 15S, plus one or two other top tier air coolers still favourably compete with a considerable percentage of AIO's, and do it quietly.

Not my experience. A few years back myself and a friend both tested this hypothesis. Both of us saw the same percentage increase in performance as percentage increase in frequency. A minor fluctuation or two, but other than that hypothesis verified.
