Hello everyone,
Finally I think I discovered the real problem that was slowing down my HP Z840.
Like suggested, I took out all hardware that I had installed myself. I also disconnected the second SSD, and the four HDD’s that are inside the system and disconnected the ethernet switch.
I didn’t do a clean install yet because I wanted to try to get the cause on the current install.
After rebooting the system with only the SSD with the OS and a few Apps installed on it turned out that this was working normal. Everything was fast and snappy. I also could open the context menus in Sorenson Squeeze and Avid Media Composer without any problems. This wasn’t possible before.
Then I connected the second SSD again. This drive is still empty, so it didn’t cause any further problems to the system. Again, everything like it should be.
As third, I connected the four HDD’s (RAID5) again that are sitting in lower bays of the Z840. It’s going to be boring, but everything was still superfast and snappy. Wow!
The sweat started breaking out on me because this was meaning that Host Bus Adapter from my Avid Nitris DX or the Sonnet Allegro FW800 FireWire card was causing the slowness. Keep in mind that I bought this refurbished Z840 so that I still could use this Avid Nitris DX hardware accelerator and A/V connection box.
The HBA of the Nitris DX was added again in the prescribed PCIe slot. This is slot 5, that has been switched from generation 3 to 2 via a jumper on the motherboard. Restarted, and everything worked fine, first without the cable plugged in from the Nitris, and then also with the breakout box connected. Avid Media Composer recognized the Nitris. As test I runned an HD-SDI cable from the Nitris into a Blackmagic Design Ultrascope card inside my older Mac Pro 4.1. The Nitris can generate several test patterns and these where immediately to see and to measure on the scopes of the Blackmagic card. So, Nitris DX working like charm and without any problems!
Lastly I putted back the Sonnet FireWire card in slot 7. Unbelievable, but everything was still fast and fully working like such a system has to work.
How in heaven’s sake can this be possible? What could then be the issue that is breaking my nerves for the past weeks? Well, hold on because here it comes!
After plugging back in my TP-LINK switch the system slowed down again and became unworkable. The menus didn’t open anymore like before. One mouse click became two clicks again, and so on.
So, my first thought was that this switch wasn’t compatible with Windows 10 Pro. If I pulled out the ethernet cable everything started working fine again. This switch is connected to my system so that I can use my three Avid Artist panels. The Avid Artist Mix, transport and Color panel can only be connected via an ethernet cable. As even most advanced workstations only have 2 ethernet ports it is suggested to use a switch if you use more than two panels. These panels communicate via the EuControl protocol with the system and dedicated software applications. All my three panels have another IP addresses to avoid problems between them. The panels were all recognized by the EuControl software and worked, with delay, in Avid Pro Tools 11.3.2 and Avid Media Composer | Ultimate 2019.12. To see if the switch was the problem I quitted the EuCon software and suddenly everything got faster again. So, there the real devil came out of his box. It’s the EuControl software that is causing all this delay and slowness! When I restart EuCon it is not working. When I disable it, everything works like the best. I deleted the EuCon application (version 3.3.2) and installed a newer version (3.4) that was certified by Avid in their latest readme file for Media Composer 2019.12. This wasn’t working either. Even with the switch disconnected to the system it was already slowing down everything again. On the Avid Artist support page I even find more recent versions of this software (19.12.1), but I don’t know if this also can be used with the smaller panels that I have. I believe that this for the bigger S6 mixing consoles from Avid. So, now I first have to ask Avid what’s going on with this, and probably make a support case. They are still going to say that Windows 10 Pro 1909 isn’t approved yet, the processors in my system are not certified by them, and my amount of memory isn’t tested.
Could this issue be the one that is mentioned in the HP-document from early October 2014?
Any ideas how such a thing can happen? A small application that slows down a whole system?
Without doing a clean install so far, I now first going to install all the rest my software to see what happens how the system performs. When I have done that I will wipe everything clean and a fresh install of the system. I guess that is the best thing I can do. Any suggestions are still welcome!
Thank you all very much for you help, thoughts and precious time to help me figure out what was going on with my as good as new HP Z840!
Greetings!
