Budget 4k livestreaming hardware and settings (simultaneous 4k to youtube & 1080 to facebook)

1st 4k stream from PIC's youtube channel

https://www.youtube.com/watch?v=dd6Z248_m8Y
so sharp to watch in 4k monitor
after much experiment in my own channel...https://www.youtube.com/winelfredpasamba/

Hardware:
Dell XPS i7-4770, 2x 8gb ddr3 (dual channel), Nvidia GTX 1050Ti, Camlink4k (for DVX200 camera @4k30p over optical 1.4 HDMI), Decklink 4k mini pci-e (for ppt laptop @1080)

Notes:
  • i7-4770 only has 16 pci-e lanes. gtx 1050Ti uses also 16 lanes. decklink mini 4k pci-e needs 4x lanes more for 4k.
  • need old cheap xeon (w/ 40 pci-e lanes) to add more 4k inputs w/o lagging.
  • i7-4770 only has 2 memory channels. it used to be 8gb one stick, adding another 8gb stick enabled full utilization of both channels doubling the memory bandwidth to 25GB/s specification.

SOP / EGW Those who neglect to prepare for the Sabbath on the sixth day, and who cook food upon the Sabbath, violate the fourth commandment, and are transgressors of God's law . All who are really anxious to observe the Sabbath according to the commandment, will not cook any food upon the Sabbath. They will, in the fear

Sabbath Cooking Excuses Investigated

Sabbath Cooking Excuses Investigated Copyright 2016 Winelfred G. Pasamba Foreword "God means that testing truth shall be brought to the front, and become a subject of examination and discussion, even if it is through the contempt placed upon it. The minds of the people must be agitated. Every controversy, every reproach, every slander, will be God's means of provoking inquiry, and awakening minds that otherwise would slumber."—Testimonies for the Church 5:453. ChS 159.2 This is a very difficult, very shaking, very testing, very new and controversial (for many who are not oriented) topic and I request the readers not go to Chapter 3 & 4 unless they have read Chapter 1 & 2.  If you go directly to Chapter 3, you probably will be highly uncomfortable if you have no testimony of avoiding cooking on the Sabbath. Readers need utter humility and gratitude-to-God, for this material not to offend them.  Love for God must be more than love for food, love for comfo
