Hey guys. First post here, but I've run into a troubleshooting issue for a friend and have no idea what's going on. It's driving me nuts
First, he bought a brand new Z840 from HP. We're both in the pro field of video (we own our own production companies) so this system is for editing. He's mainly shooting 4K XAVC on a Sony F5 and does a lot of 1080p delivery. What we've found on the new system is 4K playback is abysmal. Premiere CC2015.4, CC2017, and even in straight VLC player it's just not good. We've tried playing directly from his internal SSD (PCIe) and from a QNAP NAS over 10Gbit.
I have a system I built almost 4 years ago with an updated video card and I have no issue with playback of these files, or from the extremely similar 4k files from my Sony FS7.
2x Xeon 2.1ghz 8-core CPUs
Windows 10 64bit
One thing to add: The power supply in the workstation is some kind of proprietary unit, so not easily swapped out. There were only 3x6-pin cables free, and the GPU uses 2x8-pin. We had to use some adapters to get the 1080 hooked up. We ran Cinebench like this and it worked absolutely fine. In fact, it did incredibly well in both tests. I'm just wondering if this could possibly be an issue. HOWEVER, Adobe seems to claim that any video playback (in Premiere at least) is done strictly on the CPU, and not the GPU...
Please don't suggest he goes out and builds his own system. He's not computer savvy, and he wants on-demand support. I'm doing this as a friend to try and help him out.
