DVC3 GZM random disconnects

Postby Ant0n1z » Thu Jul 16, 2015 7:38 pm

I strarted a thread in DVC2 and noone has replied yet.
Maybe here I will get some attention.

I have this light project which is 18Mbytes for a night club

Code: Select all


Some background info.
Light project was created using DVC2, file will NOT load on DVC3.
dvc.exe will consume up to 1.7GB of RAM and will pop a message that it has ran out of memory.
Eventually DVC3 will start but the show will not be loaded.

The loading time on Virtual Controller 2 is on a new computer 37 seconds
(previous i7 with 6GB RAM needed 94 seconds to load that file,
so the club owner bought a new computer to save that 1 minute)

Computer Specifications are as follow
Intel CPU Core i7-5820K (2011-3,3.30GHz/15Mb)
MSI X99 Sli Plus (2011-3, X99s, DDR4)
32GB Crucial RAM DDR4 2400MHZ Ballistix Sport
Kingston 240GB SSD HDD
Windows 7 Pro x64 SP1
Corsair PSU 750W RM Series 80 Gold Modular RM750
Sapphire VGA PCI X R5 230 1GB

The show is needed to play continuously for a little more of 5 hours every night.
After the computer upgrade, 4 nights everything was going OK.
Last 3 nights, after 2-3 hours, the USB interface gets lost as if it got disconnected.
Noone pulled it, noone ejected it from the bottom right of the computer desktop.

Firmware on the controller DVC 3 Gold is 1.20.

I had the same problem on another DVC controller (512 DMX) for a second club,don't know exactly specs on it,
and I had to use a REALLY old computer (bought in 2008) to make it work.

How do I fix this? Is it something incompatible for example the USB 3.0 ports?
Any suggestions are appreciated.

Changing to USB 2.0 worked for a couple days but last night it happened again.

Random disconnection often comes from a :
- A USB cable issue
- A USB port (computer) issue
