Win7 PRO 64bit SP1.

AMD 1950x

Patriot Viper 4x16 GB RAM 2400Mhz

MSI Gaming pro carbon /ac

MSI GeForce 1080 Ti

PSU 800W


Newly installed system, the latest drivers, bios and chipset.
I have not installed automatic patches for windows yet.


Error ntdll.dll - on all activa core, when trying to decode h264.mp4 video (Windows Media Player), and lack of ability to open web pages with video for example youtube (IE and Mozilla).

But when I use only 8 core everything works perfect?!

Is there any patch or hotfix to fix this problem?
