  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!
  16. 10 G is getting cheaper and cheaper! One option to get cheap into 10G: D-Link DXS-1100-10TS - 8 port 10GBASE-T, 2 port SFP+
  17. As written in few postings before I have a very high success with using Win 10. We are building machines for over a year now (Win 8.1 before) with it and the performance increased a lot. To be honest. Yes it was a long and hard way to go there. But I dont wont to miss it anymore! Using a Win 7 machines feels like a time travel now. The easier way and of course the more expensive way is to use Win 10 LTSB. Still you need to tweak it but the starting position is much better then with Win 10 Pro. If you are based in Europe send me a PN and I can tell you where and how to get it if you dont have a dealer for it. Its not simply offered in a online store but Im happy to help!
  18. From my experience I can unfortunately say notging but bad things about these Asus boards! To make things better I recommend you the following Bios tweaks. Turn off: - Hardware Prefetcher - Adjecent Line Prefetcher - Intel Adaptive Thermal Monitor - Advanced Intel Speed Step ( This is just for the older CPU Generation! With the new Xeon W and Xeon Scalable you need to turn it on) - CPU C States Turn on: CPU Turbo Mode General things about Asus X299 Boards. Have a look at the PCI lanes. What is the exact configuration of your cards? How are the SSDs connected? Do you watercool the m.2 card? This one will get into thermal throtteling very fast! I can run enterprise SSDs at 70 degrees for 24/7 but an m.2 is just rated at 40 degrees until it goes into thermal throtteling. Please stay away from m.2 disks. They are not meant to be used in such a scenario! Verified and tested from me: Intel P4500, Micron 9100 and for max speed Samsung PM 1725a (PCIe slot model for full 8x Lanes and 6200 MB/s) You can get consistend data rates for hours out of them but not from m.2 disks...

  19. Hey People. The current e2 firmware EDIDs seem to create problems in combination with AMD cards and WATCHOUT. The problem can be solved by using and emulating EDIDs in the graphics cards. If someone needs EDIDs you can write me a PN. One problem was actually solved by using an old 1080p60 edid from e2. I always use internal EDIDs. Thats preventing lots of issues. Jochri
  20. I used this tool on a couple of shows: https://www.bome.com/products/bomenet Cross platform compatible and super easy to use. Also in combination with their Bome Box!
  21. Some updated informations on Win 10 versions and hardware specs: I recently had the situation with our current machines and while building our new machines that the current Win 10 1709 does not deliver the performance I expected. Here some links/articles: - https://www.neowin.net/news/windows-10-fall-creators-update-fixes-the-directx-9-memory-allocation-bug - https://answers.microsoft.com/en-us/windows/forum/games_windows_10/windows-10-fall-creator-update-ver-1709-breaking/8d564435-4a8e-46c5-8622-db8caab72cb6 - https://medium.com/changewindows/i-dont-want-microsoft-to-release-1709-914728ba7782 No problems with our standard win 10 image so far. But with the Fall Creators update I run into lots of performance problems. Especially playing ProRes files. HAP doesnt seem to be influenced by this. Google: Direct x9 + Fall Creators Upgrade.... Lots of people running into problems... Same hardware and with just the Creators Update: No Problems with watchout. So I would say: stay away from the fall creators update when building a Win 10 image! Means also: If you choose XEON CPUs, which I think is the best choice now building Watchout machines, Microsoft wants you to use Win 10 Pro for Workstations. Which means: 1709 (Fall Creators Upgrade) as this is the rollout version of Win 10 Pro for workstations. The consequence I took from this experience leaded me to the decision to go for WIN 10 LTSB. The Licensing was easier than I expected and volume licences gives you an easy path for reimaging and upgrading the machines when neccessary. I would recommend to go to a shop who is specialised in Win 10 licensing. If you want recommendations you can contact me per PN. Its nearly 3 times more expensive then Win 10 pro though. By the way: This document shows that with Win10 Pro For Workstations you gain the right to use the enterprise version: http://www.reckzigel.at/wp-content/uploads/2017/10/Windows10ProforWorkstationsEdition.pdf UPDATE: Just talked with the license dealer: You need a "qualifying" system to upgrade. So no free Win 10 LTSB with the Workstation Version. It will still cost you arround 300€ per LTSB License. Still compared to the troubles of activating lots of machines and building the Image I would say its worth the price... Conclusion: 1709 Fall Creators Upgrade => Stay away from it!!!! 1607/ 1703 =>Tested and save version. We did some big shows on it. New machines with new Intel Xeon W: Go for the Win 10 LTSB version with Volume Licensing through Win 10 Pro for Workstations license or directly from your dealer. Not tried yet but a possible solution to the problem if someone wants to try: https://www.drivethelife.com/windows-10/fix-directx-errors-after-windows-10-update.html PS Some more nerdy tech stuff: While until now Intel Speed Step technology needs to be deactivated to prevent Watchout from running out of sync on the new Xeon-W CPUs this feature must be activated to allow the CPU to go into turbo mode and use all the speed possible. Not tested for sync yet but keep you updated. Check with your specific mainboard / CPU combination. Why changing to speed step now?: Intel implemented a technology called speed shift: "Specific jumps in frequency are reduced to around 1ms with Speed Shift's CPU control from 20-30 ms on OS control, and going from an efficient power state to maximum performance can be done in around 35 ms, compared to around 100 ms with the legacy implementation." This is very important when syncing different machines. If this is working as promised that also gives us a significant performance boost. Minimum CPU Speed should be set to 100% in Win so in theory efficient power states should not matter to the CPU and just the jump from arround 3,9 to 4,3 Ghz can be done now in 1 ms instead of 30ms. XEON W-2145 is the next weapon of choice. Having an all core turbo of 4,3 Ghz (measured) and trying to get even more out of it.... Some might ask why not choosing the 10-Core Xeon W? It has a slower base speed which means also a slower all core turbo. Didnt check it myself but as the iMac Pro is using variants of the Xeon 2145 and 2155 you can see in this benchmark that the 10 core is getting significantly slower in All Core Turbo performance compared to the 8 core on full load. http://appleinsider.com/articles/17/12/27/first-look-benchmarks-put-apples-entry-level-4999-imac-pro-to-the-test The only faster CPU configuration for a mediaserver would be the XEON Gold 6144 in a dual CPU configuration which would make up for the slightly lower clock speed. However this would cost arround 7000 $ / 6000 € per dual cpu. This would be the choice if you would use the machine also for rendering applications... And here some theory about what I wrote https://colfaxresearch.com/xeon-2017/ Conclusion: Current fastest Watchout CPU Xeon E5 1650 v3 / v4 and for new builds Xeon-W 2145 or Xeon Gold 6144 in dual CPU mixed usage systems. If you dont want to go the Xeon way i think the i9 7900x with 10 cores and an all core turbo of arround 4 Ghz is the way to go. ( I would always choose the Xeons)
  22. I agree with most of Dorians specs. However I think m2 SSDs are getting way too hot under continous load even when there is active cooling. The surface is just too small to handle the heat. I can recommend Intel P4500 / Micron 9100 & 9200 SSDs. They not only give you constant throughput but also better warranty options from my experience. They are made for 24/7 use. The intel x550 is currently the standard ethernet card of choice. You can go for atto too. There are lots of optimization options even in a network card. Also look at this topic: http://forum.dataton.com/topic/2745-new-display-machine/
  23. I think the UA-1010 OctaCapture from Rainer is an excellent choice! If you want to go more high end I would like to mention the Focusrite 16 Line. https://pro.focusrite.com/category/audio-interfaces/item/red-16line Its not on the market yet but it also has a meterbridge which can be very useful when someone complains about Watchout not playing sound . Then you just point on the meter and show him the moving meterbridge... But what makes it a real good choice in my eyes is the support of redundant DANTE audio networking. Edit: Not sure if its really redundant but having two ethernet ports at the unit might be useful for this configuration... Lots of productions putting a stagebox on top of the Watchout racks anyway. So I think its just the next logical step to avoid the D/A A/D conversion. Welcome to the future... Some productions over the last months also had more then 8 channels so I think the 16 channels are a good choice but it all depends on the type of shows you are doing.
  24. To get you started with win 10 tweaking there are essential tools I can recommend: 1. Ultimate Windows Tweaker: http://www.thewindowsclub.com/ultimate-windows-tweaker-4-windows-10 While you can do all these Tweaks in der Registry and through different commands this software takes a lot of the work away from you. 2. http://winaero.com/download.php?view.1832 This removes Cortana from your PC. It will eventually also stop your search function from working but this should be deactivated anyway. 3. http://apps.codigobit.info/2015/08/win-x-privacy-helper.html This will remove even more unwanted Win 10 applications. We are currently testing Win 10 Pro for Workstation as this will be the system which gets delivered with workstations from the big vendors from now on and in the future and which might get the most attention from Microsoft for our field of applications. However this will cost you arround 200€ for an upgrade or 440€ if you just buy it alone... And there are 2 Versions of it. Max 4 Processors and more than 4 Processor Cores. Still waiting for the delivery of some parts for the next generation machines to be able to test the new win...
  25. Hey AVTermite! Nice Nickname! We run Watchout very successful on WIN 10 on more than 20 machines for around a year now. We also builded machines for some clients based on our WIN 10 image. About hardware: Get the fastest single core performance processor you can get. Currently this is either the XEON 1650 V4 or the i7 version of it. We are experimenting with the new generation but this is still under development and I can't tell you exactly what to buy if you want to be safe! Also think about PCIe lanes. With additional SSD storage and maybe capture cards you need a lot of storage! Your choice just got 28 PCIE lanes. If this is enough for you OK. But you will be at the limit of what is possible very soon with PCIe cards. From the current Intel range I just see the i9 7900x as suitable for WATCHOUT. Still I prefer the new Xeons. They are even faster than the i9. Dont think about Turbo Boost 3.0. The most important thing is a stable frequency as high as possible for as many cores as possible. The indicator is the ALL CORE TURBO. Means how much speed do you get if all cores are working on full power. The WX7100 is a good choice. Get it together with a S400 sync card to sync outputs for LED walls. Emulating EDIDs is a absolute must have! Worth spending the money for a professional card. If you use ACTIVE adapters you get every signal you want out of the card. The only adapter i can recommend is the CLUB 3D DP to HDMI 2.0 Besides the system SSD stay away from m2 SSDs. They are getting way to hot and drop in performance. There are some versions with active cooling but nothing I would put into a machine. We prefer Intel or Micron PCIE SSDS. They are made for 24/7 usage and deliver up to 3250MB/sec. Regardles of what people are saying, its fine to also run them in raid configurations. Our current demonstrator goes up to 15.000 MB/s. Think about running uncompressed picture squences in 4K. Every layer of 4K uncompressed video will need arround 1200-1600 MB per second. Of course this comes at a price. These disks are not cheap and they might fail like others do. But a least you will have a red LED at the back of your machine reporting the problem. You also got long waranty periods on these disks so in case they fail you will get a new one fast. About RAIDs in general. I would trim the machines for absolute performance. A software raid 0 can give you more then 6500 MB/sec on your machine with 2 PCIE NVME disks. Backups should either be made through a content management workstation or on a second backup system. Usually on big productions we do both! Some Raids I got im my hands had caching functions activated. This is totaly dangerous because this function might work good for some small office files but not for delivering stable video streams. By the way - dont buy SATA SSDS go NVMW for the IOPS. These are relevant if you want to play uncompressed TIFF or TGA sequences. Also a lot of RAID 5 controllers are the bottleneck for this. A single Micron or Intel PCIE SSD should give you the storage and performance needed. 10G Network. Absolute standard if you build a machine now! And only with Win 10 you will be able to use the whole 10G. Of course depending on the content. We found that NVME on Production and Display Computer gives you the best performance. 10G cards are not expensive anymore. Intel X-550 is the card to buy. Bios: Please deactivate all energy saving functions on the processor: C-States, Thermal Protection and most important Intel Speed Step technology. If you got these functions active the machines will run out of sync!!! The real challenge besides the right hardware choice is of course Win 10. Its a beast to configure and we spent a LOT of time testing different configurations. Once its running its the best system you can run Watchout on. We are currently able to playback 4x4K TGA sequences out of one machine and I guess it will be even more with the next generation we are currently developing. Besides the regular Watchout tweaks we got a list of arround 100 more tweaks for WIN 10. In the end its really a lot to do and you need profund IT knowledge to get the best performance out of the machines. It really becomes an industrial PC and when looking at the taskmanager there should be 0% CPU load and the absolute minimum of processes running in the background. We customize systems for usage as media servers and if you need help you can write me a PN. If you did all this you have to test your setup a lot to provide absolute stability and performance. The advantage of building your own PC can become a disadvantage if people build machines which crash and dont deliver performance. Thats why competitors of Dataton sell their machines for a lot of money. Because they provide everything from Software to hardware. Still if you do it the right way you will even be able to outperform systems which cost 50.000 $ or more! Of course high end Watchout Systems also cost a lot of money but its cool that you can build a machine which fits your purpose. The WATCHOUT advantage The question in the end is: What do you want to do with the machines?
