Hi vlado,
any idea why the sys hangs.
Thanks

It could be for various reasons, for example weak power supply, overheating etc. We had a system with four GPUs that would run fine generally, but would restart within seconds of V-Ray RT GPU being started due to overload of the power supply.

Best regards,

Hi vlado,
it was a overhaeting problem. One of the cards fan was obstructed by the sys cabling. Wish caused the vray rt gpu and the sys to hang.
Thanks for the adviced.
