[SOLVED] Will i7-3770k 4.6ghz bottleneck 1080ti?

[boriss911]

Hello, i recently had questions about i7-3770k cooling, and now i went over to GPU upgrade. I have i7-3770k in combo with 1070 strix, i am planning to get around 144fps in witcher 3, so i am planning to buy 1080ti. But, as i know my cpu is too weak for that GPU, but will that actually matter in games that dont use yours cpu at 100%? For example Witcher 3.

Shipping would cost hell to Norway, i am buying pc parts at local shop\sell site.

damn good luck finding a good deal

the 266$ 1080 ti that i saw the seller had enabled return of the card if it had issues

Right...

Guys, thanks for help with the 1080Ti. I dont know if its allowed, but i want to ask you a question. As you know i have a 3770k OC to 4.6GHz, its AIO cooled. My cpu gets pretty hot, sometimes up to 95 degrees. VCORE is 1.328. People said that i should lower it to 1.3. Can lo voltage damage cpu? Maybe some suggestions how to lower temps??

 

[SgtScream]

Not low voltage you only have the 1070 in there now? What case do you have and what is the fan configuration?

Masterbox LITE 5, fans is running at 100% now, thanks to speedfan...at idle temps are about 50

The voltage is not too high. You could try to lower it to see how low you can go before reaching instability. Just use prime 95 with avx disabled to try and induce a crash when lowering the voltage. Where is the radiator mounted?

Take the front panel of and see if your cpu temps improve.

Front

Actually when i was putting ssd in pc, my whole case was open, window too, and cpu temp was at 25 degrees!!

 

[SgtScream]

That case doesn't look like it has good front panel ventilation.

 

[boriss911]

That case doesn't look like it has good front panel ventilation.

interesting, when i hifde mozila, cpu temps fall with 10 degrees.
front panel off / no changes

actually temps are at 37 now, front panel off helped untill now, CHANGES went back to 50 even with front panel off

Im a little late to the party but ill add something that may be of great value.

As now a days FPS matters a lot, i personally have a 240hz but i cant fully enjoy it... because...

I also own a 1080ti and a 3770k, and that processor has always been the very best at everything, and therefore i havent been in any need of upgrading since 2013.

But today i realized, that EVERYGAME is capped at 185FPS.
So i was checking, done Overclock and stuff.

For some reason, i with or without Overclock i cannot seem to get past 185FPS, but CPU usage is always at 100% i tried 3.5 3.9 4.2 and 4.5, and 4.6Ghz they are all the same in regards of gaming performance, at least for the games i played.

Tried any resolution, even 720p at lowest and it will always be 185, therefore it must be the CPU.

So, i wouldnt recommend trying to overclock way beyond the limits, i would recomend 4.2Ghz is great, amazing performance and low temps...

and upgrade whenever possible, as your 1080ti and do much more than you may think it can actually do...

hope it helps mate.


ALSO: if you think my Bottleneck isnt the CPU and there is sort of stupid glitch, PLEASE let me know LOL.

I don't know about games FPS caps, cause that will depend on every game and game engine. Some FPS limitations can be disable by editing a setting on a text file, then again it will all depend on every game.

As for your question about if the i7 is bottleneck it all depend, once again, at the game. Most newer game engines, can utilize up to 12 threads or even more, so newer thread- optimized esport games can be limited by a CPU with fewer resources.
Constant 100% utilization of your CPU means that the game in question is fully utilizing all your CPU horsepower, and you have no resources left to work with. So, if the games need to resolve another "task" it will have to wait till some of the work thats been proccess on the CPU finish in order to "work" on the new task.

8 logical threads, like the ones that are available on your Core i7 are still relevant, but they will get taxed really fast as soon as you launch one of those games and try to get the highest FPS by lowering the game details and resolution, it will get even worst if you add another task while playing the game, called discord + broswer tabs, streaming, etc.
