Hello;

I have bought a new pc with these spec but when i edit 4K videos the preview completely slow down and sometimes freeze which mean i cannot edit properly.

CPU

Intel Core i7 6700K @ 4.00GHz

RAM

16.0GB @ 2400MHz DDR4

Motherboard

ASUSTeK COMPUTER INC. MAXIMUS VIII RANGER

Graphics

8.0 GB NVIDIA GeForce GTX 1080

Storage

232GB Samsung SSD 850 EVO 250GB (SSD)

931GB Western Digital WDC WD10EZEX-08M2NA0 (SATA)

232GB Samsung SSD 850 EVO 250GB (SSD) (Only for cache files)

I overclock the CPU to 4.5 MHZ.

Which hardware do i need to upgrade to get a better performance and smooth editing?

Thank you

I am guessing that your media is a long GOP codec. Since your CPU is fully loaded it cannot handle the media decoding. You better look at proxy or transcode your media to something with less decoding. Download and run MediaInfo and then go to Tree view and give us a look at what you are trying to process. Here is a sample of what we would like to see:

The video is recoreded with DJI phantom 4 pro, so it is a drone footage 3840x2160 pixel and 100 mb/s

Do you see that "Format Settings, GOP: M=1, N=30"

That "N=30" is the problem. That is the longest GOP that I have seen, there may be longer. That is very highly compressed and requires immense CPU action to decode/ The easiest probably is using Premiere Pro's new Proxy editing.

Notice my example from my son's GoPro is only N=15 so editing on my laptop is much more practical .

Why don't you run my Premiere Pro BenchMark (PPBM) and let us see your Output.csv results. This is a hardware test using Adobe Premiere Pro. There is one Disk I/O test, one CPU intensive test and two GPU assisted tests.

Also I am guessing that your media and projects are on the hard disk drive. Try just using you second SSD for all your project files and media. Hard disk drives should be relegated to archiving and backup only.

If you really want a great project/media drive fill that M.2 socket with one of the new super speed SSD's see my test data on various forms of storage media
