Need help making a build for a friend

[wolar]

He can wait for 2-3 months, i do not know which will be better for him tbh, thats why i tried to make a balanced build.
The 7700k right now is 250gbp and the 8600k is 240-270gbp, choosing either of these will benefit him now, i do not know if it will be the same in 1-2 years though and ryzen doesn't get better, also which of these cpus(7700k and 8600k) is better for high fps.

The CPU with the higher clock speeds are likely to be better at higher frame rates because CPU load (in particular, serial workloads,) scales to frame rate but, doesn't typically scale as much to resolution. If your buddy is going to run a display >= 120Hz, then go with whatever can clock higher. If 60Hz is the goal, then it probably doesn't matter.

An example would actually be my system. I run several games at 4k that fully tax the GPU but, the 3930k keeps up no problem, and this CPU has been around for over half a decade but, I'm also not cranking out insanely high frame rates which lessens the burden on the CPU.

It's perfect, the only issue is it's a bad time to buy PC parts. Wait till Bitcoin crashes.

I honestly do not see it crashing any time soon :/ Awesome, i will tell him to get the i7 then.

Thats going in my sig too!!

i do not know the differences between the lg, zowie and asus and which one is better so ill recommend the asus one you posted or the zowie.

The build is complete but i have some problems with the cpu temperature. Case is cool, cpu cooler is the h5 universal, motherboard is the z270 mark1.

Cpu is set to 4.2ghz, core volt at 1.225, PLL at 1.1v and i also reduced some other voltages which i cannot remember right now.
I also configured the fan speed of the cooler to be more aggresive.
After about 10m in overwatch cpu reach at 75C, with p95 after about 30seconds it reach 90c, i stopped it but after some minutes it could reach 93-95 i believe which is too high.
Is it normal? Is there any other way to reduce the temps ? Ill try using 1 more fan with the cpu cooler and if that doesnt work i will re-install the cooler but i think it was correctly installed the first time..

Edit: Temperatures and voltages were monitored using hwinfo

What's the ambient temp of the room? Seems very hot for that clock speed and vcore. If the room isn't hot, you may have terrible air flow. Check/adjust all fan profiles to 80 or 90%. Maybe try it with the side cover removed, and a desk fan blowing in. I find that stress apps like p95 and IBT are not that useful anymore on newer CPUs, because they cause it to overheat quickly. I only use AIDA64 stress test these days to check stability of OC, usually un-checking the "stress FPU" and stress cache" options. Gaming doesn't tax it as much anyway.

sounds like the cooler is not mounted right. go ahead and reinstall it.

 

[wolar]

I will first try the latest bios(the one installed is some months old) and reset everything except core voltage to 1.225-1.25. If that doesnt work ill try with another fan on the cooler and after ill reinstall the cooler, i honestly do not believe the installation wasn't correct but ill do it anyway to check.

Thanks for the help.

EDIT: OKAY scratch this. You've already built it some time ago didn't notice the dates

You will need to look at all voltages and tweak accordingly. These chips have spiky temp behavior, Coffee Lake is no different and the H5 isn't a fantastic solution for this kind of chip. BIOS updates can help set some things right in that sense.

Focus on the following:
- VCCIO / VCCSA - as close to or at stock volt, even with XMP ram you can dial it down in most cases
- LLC. Play around and find the lowest temp setting that also helps with vDroop. Sometimes a tighter LLC works well for this, some boards prefer it really loose
- AVX Offset. Last resort. Effectively you will find the CPU running at lower freq more often than you might like, but this will keep temps in check in a big way. This offset effectively lowers the multipliers when there's an AVX load.
- A better cooler. The H5 is 'sufficient' but when you OC it runs into constraints fast.
- Ambient temp and case airflow. Most reviews test at 18-20C ambient. You only get similar results if you have that ambient temp inside the case.

Thanks for the reply. VCCIO is the ram voltage? Also what is LLC? do you mean PLL ? Ill try using the adaptive for the core voltage as well instead of manual.

Ambient was around 25-30C , case airflow is more than sufficient.

LLC is Load Line Calibration and PLL stands for phase lock loop voltage. PLL isn't a really important OC setting, you could usually lower it a little while maintaining stability, thats it.

But LLC is very important, it allows you to hold a steady vCore under load. What happens is, you set a vCore and during load, that vCore drops a bit from what you've set it at. LLC counters that behaviour, making your set vCore more reliable and forcing it to what you set. This in turn may allow you to use a lower (adaptive) vCore to start with, because a stronger LLC setting keeps it at a similar value at load and you're no longer 'compensating for the drop'. I hope that explains it, otherwise this pic may help:

Here you can see how voltage can change during prolonged load:

there is a dip before starting the bench and then an overshoot to 1.33v, the CPU then gets 1.31v 'under load'. This is an example of vDroop, and later during the run, it drops down to 1.30v. A stronger LLC setting would eliminate that behaviour, and allow you to set the vCore not at 1.33v, but at 1.31v and 'hold' that voltage all the time. Its about finding the best balance, best being the balance that gives the lowest temperature without sacrificing stability.

Ideally what you want is a straight line.

VCCIO is tied to RAM but its not the RAM voltage itself - that I would not touch.

Will the noctua NF-F12 INDUSTRIALPPC-2000 pwm make a big difference ? I still didnt' get to try the settings but if it doesn't work will this noctua fan do the job or will he needs to buy a new cooler?

It can get really hot in the summer here that is why i am worried(32-42c).
