  1. Switch off the interrupt moderation in your production PC card and your clients. Maximize send and receive buffers. Intel cars are cool but if you want to reach maximum performance go for Melllanox or Atto cards! Keep in mind also the max write speed of your media disks. M.2 is getting hot after 30 seconds. So go for u.2 or PCIE cards. PM1725a Intel P4510 or HGST....
  2. I currently redesign the Wiki. Please find the Bios tweaks here: Sleep States: Talking about real time applications you should get rid of all settings which makes your CPU going to save energy. They are often called C- States and should be set so that your PC never sleeps. Sometimes you can also find a setting which is called "Block Sleep" (S3 State) So thats what you need to check and set to not stop your mediaserver from working at full power. Some mainboards have high performance modes. This is a good starting point. But dont just use auto tuning settings! Intel Speed Step: Activate or not activate? The answer is it depends! Older CPUs, I would say before 2017 needed a certain amount of time to go from idle to full power (60-80ms). This milliseconds can cause too much delay to your mediaserver system. So on older systems it is neccesary to deactivate this setting to always run the CPU at a certain level to avoid the delays. - Since Intel introduced the Speed Shift function this setting changed. In a short way explained. Speed Shift accelerates the speed at which the CPU can go to full power to just a few microseconds(1-3ms). So activate it if you are using new hardware that supports speedshift! The CPU should run at full speed without changing frequeny up and down. You can verify this easily with the task manager. The best way is to force the CPU to full power through the Bios. Memory Map above 4Gb: ON (Necessary for GPU memory) CPU multicore support: ON Intel Turbo Boost: ON Hyper threading:ON Adjacent Prefetch: OFF Hardware Prefetcher: OFF ISOC Mode: OFF Home Snoop Mode: Standard ASPM Mode: OFF (Otherwise PCIe devices are allowed to safe energy and need to much time to wake up when needed) I recommend reading this document where the picture is taken from (page60): https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xeon-e3-1200v5-vol-1-datasheet.pdf
  3. Hey Weckmuller. The intel SSD 750 series is quiet old right now. Go for Samsung PM1725a or any 8Lane SSD. Intel P4510 is also ok. Depends if you want to play uncompressed or not.
  4. Get the latest AMD driver. They added the functionality to manually force your GPU fan to run at full speed all the time. This might help. Do you use high quality active dapters? Also try what Thomas said. Get a new generation GPU might also help and can be easily changed without settimg up your whole machine completly new.
  5. Do you use high quality active adapters?
  6. I built based on a Xeon W-2145. (Xeon w-2155 is also ok if you want to use the machines for rendering etc.) It will run at 4,25 Ghz in all 8 core turbo mode. Note that you should populate the Ram slots with 4 memory channels. These are very important for uncompressed workflows! If you want to spent more money: Im testing Xeon Gold 6144 and 6146 this month. They have 6 memory channels available. These are usually Dual CPU boards so they come at a certain price point. Its also a massive difference if you want to play 4K 60 or 4K0 streams. With TGA(A) the current maximum is 4 layers of 50p and 3 layers of 60p content Keep an eye on the bios settings. I made a list of Bios tweaks here. https://watchlab.net/wiki/Tweakinglist Win tweaking is super important but the Bios level tweaks can destroy all your work or make it succesfull. So dont forget to test that! By the way I just tested on of these active cooled 4xm.2 PCIE adapters with and without intel VROC. Besides the WX 9100 blowing all the hot air directly inside ? Im not very happy with these devices. If you use them you should really go for enterprise ssds but also they are temperature throttling...
  7. Did you check the following points? https://watchlab.net/wiki/Troubleshooting_FAQ (Happy for more advice on this!) What EDID are you using?
  8. Did you checked the "syncronisation chain master" button in the display settings? Without it the system will not deliver the power it has.
  9. Some things to check: - How long are your file names? - How many hops (switches between production and display) does your network infrastastructure has? - What switches are you using? - Do you checked cables? - I can have a quick look at the project file if u pm me.

    4х4K Capture

    Well I would say if you can wait then go for the new Newtek HDMI 2.0 NDI converter box and buy 4 of them. If you need something now go for the Decklink 8K which has 4 12G SDI Inputs and put a simple HDMI to 12 G converter in front of it. For handling 4x4K inputs I wouldprefer a WX 9100 which give you a lot more overhead but I would give it a try first...
  11. The goal should be to have the CPU at maximum speed state and to minimize the time to ramp up the speed. I will add a little video later. Did you set the CPU minimum frequency to 100 % in Win 10 edvanced energy settings? This should be done in every case independent from the os! If so the CPU will still ramp up and down a little bit, but arround the maximum possible speed of 4,3 Ghz. "Overclocked" is not the right term in my opinion as people may think this is a dangerous thing. You can not overclock a Xeon CPU in the way people think about overclocking. You are setting the Intel turbo 2.0 state for the maximum speed. And that is where a CPU is at peak performance. The 4,3 Ghz are the so called " All Core Turbo" for when every core is at max level. Stay away from tools that will simulate a load on the cpu to force it for full speed. Theses tools are interfering with Watchout. CPU speed should be handled with Win or Mainboard only. So to make it a little clearer. Usually on older CPUs the enhanced Speed Step technology will make the cpu go down to idle mode for when there is no load. For example no video playing. If you start the video the CPU needs to wake up from the halt state and speed up. This may cause stuttering playback issues. Im on Win 10 since Jan 2017 now and before on win 8.1 so my experience with win 7 is limited in this area. But I think turbo mode should always be activated. On some mainboards you can decide if the CPU or the OS is going to handle the speed shift. I prefer the OS to handle it in Win 10 as the Speed Shift Technology was developed with close cooperation with Microsoft. On Win 7 I would recommend to hand over the task to the CPU if possible. But this is speculation from my side as Im just using Win 10 LTSB for now. These settings are super important and I saw a lot of machines with wrong settings in the past. So this is more of a general advice to please check what your bios CPU energy management is set to! And its getting worst with consumer hardware as many of theses mainboards are even more optimzed for energy savings. i think buying a LTSB license is a small price to pay considering the general price of even a cheap Watchout system. You dont have to go for the IOT version as this will also be not so easy for licensing. Win 10 Enterprise LTSB will do the job. So before throwing away Win 10 (Yes it is hard work to make it work but can be done with Pro edition) please try the LTSB version which is the perfect starting point for industrial applications.
  12. Didnt tested with Win 7 so far but its just a Win 10 feature I guess. What is your mainboard / CPU? You should be able to hand over the task to the cpu. https://pureinfotech.com/windows-10-fall-update-enable-intel-speed-shift-skylake/ Never been happier than with the latest Win 10 LTSB update and AMD 2018Q2 drivers!
  13. Of course a question of resources but we sometimes apply an additional HD output just for timecode / countdown display reasons. Feel free to use it (50fps). Send me a pn for the simple ae project. vimeo.com/267041786
  14. I just want to quickly share some basic network tweaks. When dealing with 10G and 40G networks there are settings in the network drivers which become very important for the file transfer speeds. As the Intel X-550 series card is one of the most used cards I will explain with their settings. Most other cards use the same names for the settings: Interrupt Moderation: OFF / The interrupt moderation prevents the CPU from getting the load from the network card. Means when to much traffic is incoming the network card will not give away load to the cpu but will simply "moderate" the incoming files to a level it can handle and also to save energy. While for many server applications this might be the right way of handling traffic especially WATCHOUT has no load on the cpu while recieving files. So you can use the resources to support the network card. The same setting for interrupt moderation can be found in the driver under the performance options menu selection. Switch interrupt moderation: OFF Send & recieve buffers: Set to the maximum your card can support. RSS queues: Set to the maximum. A good way of testing these settings is to use a simple windows network file transfer. Open up the task manager and see what happens with the cpu load with or without interrupt moderation. Multiple file transfers connected between 10 G / 40G to 10G / 40G pcs load the cpu to more then 75% on a new 8 core machine. When handling large ammounts of data these settings can safe hours of transfer time. And while the Intel X550 is a good product also think about RDMA capable cards and manufacterers like Mellanox or ATTO when choosing the right network cards. The differences are bigger then one might think - so are the options of the network card settings which will also expand. Didnt tested with many NDI channels so far. If anyone might share their test results in combination with input moderation settings that would be super cool. Whatever you do keep testing! By the way. Just finished a poduction in china where bad unshielded network cables were creating big problems. So use high quality cables for the connections! Otherwise they might create lots of problems.
  15. As a fist formula I found out the following scenarios to work best for us: Up to 3x layers of 4K video I use tiff because of the file size. 3x 4K tiff @1200mb/s = 3600MB/s = single 8 lanes pcie SSD or dual u.2 / pcie x4 SSD To use 4x layers of 4K video I use tga because of the better performance 4x4K tga(a) @1600mb/s= 6400MB/s = dual pcie 8 lanes ssd So the better performance comes with the price that you need nearly double SSD bandwith. For HD layers I count 1x4k layer as it would be 4 hd layers: Its possible to playback 4x4K tga without problems and modern SSDs become more and more afforable. Keep in mind that there should be at least 30% overhead to the given specs of the SSD read speed for smooth playback. Have a look at your pcie lanes! NVME storage is also important when uploading to machines. Theres a significant difference between SATA raids and NVME while uloading!
