Here more CPU power is present but fails!
Only single socket used Xeon E5-1607 v2 four core 3000 GHz processor with same GTX 680 graphics card on an Asus Z9PE-D8 WS dual socket server mainboard causes stuttering with same software and 4K UHD films. For example.Ī two core i3-3220 CPU with a GTX 680 graphics card on a Z77A-GD65 MSI mainboard with Mega codec pack, plays 4K UHD films without issues. This issue sometimes varies from mainboard to mainboard. Your bottleneck is not your graphics card, but maybe your CPU, but maybe your mainboard. If you use a GPT file structure, a non-UEFI graphics card bios brakes. Generally all GTX 6xx graphics cards (unless you find a proper one from techpowerup's bios database) are not UEFI compliant bios installed at their date of manufacture. A MSI mainboard may provide relentless playback with your same hardware, like my old MSI Z77A-GD65. But, I think your mainboard bios is not optimized. A GTX 670 to 770 is more than sufficient.
Mainboard upgrade of HTPC? Which model? Which brand? Asus? MSI?īut, you may have to consider a graphics card upgrade to be sure. If that is the case, your processor can not be upgraded because it is the highest model, upgrading GPU may have no effect! Deadlock. If your graphics card is below %80, it is sufficient. If your processor goes over %90, problem is found mainboard bios is unoptimized. Here play the 4K content and look both CPU and GPU loads. To understand from which, run task manager. Therefore your graphics card seems ok, but maybe your CPU lacks because of mainboard brand's rom. I have also tested i7-4960X processor on an Asus Rampage IV Black with GTX 670, again no issues. My old, previously used 6 core AMD 1090T processor can also play UHD content well with nVidia GTX 670 on Asus 990FX/Gen3 R2.0 mainboard. If I disable nVidia GPU, on chip Intel GPU can not handle, it causes jump with reaching over %90 CPU load with %90 load with internal GPU.
My latest HP Pavilion 15-cs3001nt notebook with 10th generation 1065G7 CPU with GTX 1050 Max-Q GPU processor load is %60 max and CPU load is max %40. I have an old Vaio notebook processor with i7-2960XM with all core max turbo speed with 3400 MHz with an additional GTX 540M GPU, here again can not successfully play untouched 4K UHD (m2ts) files. The hack here is, probably MSI mainboard's rom is much more optimized in playing UHD films, with the help of internal Intel graphics inside CPU which also used.
Here more CPU power is present but fails! Server mainboard seems weak, unoptimized for UHD content. This is surprising! Comparing with this example, your i7 3770k is much more powerful, logically problem seems GPU power.īut, only single socket used Xeon E5-1607 v2 four core 3000 MHz processor with same GTX 680 graphics card on an Asus Z9PE-D8 WS dual socket server mainboard causes stuttering with same software and 4K UHD films.
