For power, I used the Enermax MaxTytan watt unit. These are EMI shielded and have dedicate amplifiers that auto-detect the impedance of connected devices. This implementation features an isolated design with audio channels in separate PCB layers. A de-pop circuit is also present to eliminate the annoying pop you hear when plugging or unplugging devices as the name implies. An adapter is provided so that you can connect this CODEC to a standard mini-stereo jack via the back panel.

For general audio testing, I logged into my Spotify account and played various songs on my playlist. The latter was more powerful, providing higher levels as anticipated. I am unsure of the precise model. Spoken words were recorded from the Windows Sound Recorder found under the Accessories folder in the start menu within Windows. The recording was using the highest quality settings available in the control panel for the audio device being used to record.

During playback of our recording sample, there was no perceptible distortion. Audio levels were relatively high, but with the microphone boost option, they were much lower than with this option checked. These were tested briefly while messing around with benchmarking the system. The gaming audio quality was outstanding.

When I connected to the ESS, it was like night and day as it was clearly the better option. Deferred procedure calls are a function within Windows that allows higher priority tasks such as device drivers to defer lower priority tasks for execution at later times.

DPC latency varies from board model to model and brand to brand. DPC issues show up in the form of audio dropouts and streaming video issues. Naturally, this is something that the enthusiast would want to avoid.

I used LatencyMon and let it run for 10 minutes to graph the results.

This way we can compare DPC results to other motherboards which should be more meaningful than the old format I used before. In our DPC latency test, the highest measured interrupt to process latency was That said, newer platforms with early BIOS revisions are often this way.

Ok but, since I built the computer, I've always had some issue that the computer would crash on occasion, but very not often. I can do this now. Anyhow, then it worked.

So figured, dram calc was fixing my computer. So i go and try mhz, reading my ram is quite capable of doing it and its the best performance change you can do to the computer. Then this works. Eventually i use dram calculator to find safe mhz dram timings.

The computer runs without crashing. But sometimes weird things seem to happen. Could just be random quirks but. Anyway so i cant change any ram timing to anything else but mhz and i have to use dram calculator to have my computer run without crashing. This ram should be capable to handle some timing change.

I dont know it just doenst seem like the computer runs right. Miniatura de Adjuntos. Last edited by ldrancer; at AM. Reason: bought o'. THe first picture test on this ram gives me about the same results.It may help to find the cause for interruptions in real-time audio and video streams, also known as drop-outs.

The output suggests that the Windows 8 kernel performs badly and introduces a constant latency of one millisecond, which is not the case in practice. DPCs in the Windows 8 kernel behave identical to Windows 7.

The utility produces incorrect results because the implementation of kernel timers has changed in Windows 8, which causes a side effect with the measuring algorithm used by the utility. Thesycon is working on a new version of the DPC latency utility and will make it available on this site as soon as it is finished.

If any kernel-mode device driver in your Windows system is implemented improperly and causes excessive latencies of Deferred Procedure Calls DPCs then drop-outs will probably occur when you use real-time audio or video streaming applications. For an explanation of this effect see Background information below. The DPC Latency Checker tool determines the maximum DPC latency that occurs on your Windows system and thus enables you to check the real-time capabilities of your computer.

DPC Latency Checker works independently of any external hardware. Using this tool may be helpful in the following situations:.

For more information on the Deferred Procedure Call mechanism and how an excessive DPC latency will affect a streaming application see Background information below. DPC Latency Checker is very simple to use.

Download dpclat. No software installation is required. The main window is shown below. This statistical data is queried and displayed on screen once per second. The value labeled Absolute Maximum represents the maximum latency measured since the tool was started. Use the Reset button to clear this value. The bar graph shows the Current Latency value over time.

Each bar represents the maximum DPC latency that occurred within one second. The most recent value is shown as the right-most bar. Every second, bars are scrolled from right to left and a new bar is added at the right-hand side. Latency analysis can be stopped by means of the Stop button. If the button is clicked again the tool restarts measuring of DPC latencies. In the figure below, a typical problem scenario is shown.

Occurrence of excessive DPC latency is indicated by a red bar. At a period of 3 seconds a kernel-mode driver in the system is stalling the CPU for about 3. You can find out the driver which causes the excessive DPC latencies by disabling individual devices using Windows Device Manager.

To open Device Manager, choose Properties from the context menu of the My Computer icon on your desktop and click the Device Manager button on the Hardware tab.

In Device Manager disable individual devices, one at a time. To disable a device, right-click on the corresponding item e.Latest version: LatencyMon v 6. Version 6.

LatencyMon checks if a system running Windows is suitable for processing real-time audio and other tasks. LatencyMon analyzes the possible causes of buffer underruns by measuring kernel timer latencies and reporting DPC and ISR excecution times as well as hard pagefaults.

It will provide a comprehensible report and find the kernel modules and processes responsible for causing audio latencies which result in drop outs. LatencyMon will display the highest latencies of a kernel timer and report the highest execution times of ISR and DPC routines as well as hard pagefaults.

In most cases it will also find the drivers and processes responsible for executing them. It will create a comprehensible report which also displays all sampled data in a detailed manner allowing you to perform in-depth analysis. The audio latency problem. Windows is not a real-time operating system.

All requests to the operating system are delivered on a best effort basis. There are no guarantees whatsoever that requests are delivered within a certain time frame, which are the characteristics of a real-time operating system. That is not a problem for most devices and tasks but this is bad news for audio applications which are considered soft real-time because they need to deliver data to the subsystem and the hardware in buffers several times per second.

If one or more buffers miss their deadlines and are not delivered in time it has audible consequences which are recognized as dropouts, clicks and pops.

The Windows thread dispatcher also known as scheduler which is part of the kernel executes threads based on a priority scheme. Threads with higher priority will be given a longer execution time also known as quantum or time slice than threads with a lower priority. However the kernel also knows other types of units of execution known as interrupt service routines ISRs.

Devices connected to the system may interrupt on a connected CPU and cause their interrupt service routines to execute. An interrupt can occur on the same processor that an audio program is running on. Any thread that was running on the processor on which an interrupt occured will be temporarily halted regardless of its priority.

The DPC will most likely run immediately on the same processor which means the audio application will halt until both the ISR and the DPC routines have finished execution. If execution time gets too high, the audio program may be unable to deliver audio buffers to the hardware in a timely manner. About hard pagefaults. Windows uses a concept of virtual memory which relies on the page translation system provided by the CPU.Forum World Records.

Also, Wdf Now, i reinstalled Windows the creator's edition since this is the one the Microsoft Tool downloadsi reinstalled GPU drivers, sound drivers, network drivers and the problem insists.

When 1st booting into Windows right after the installation is complete, while windows installs a probably generic Sound driver, the sound is fine despite high latency. But unfortunately that driver doesn't support many things not only on the speakers but also on the microphone side of things. Now, I was trying to find information on the Realtek website about the ALC codec and there was absolutely nothing.

I tried installing Realtek 2. I also installed the driver from the Asus website. My question and kind request is this. Do you guys also have any problems with high DPC Latency and if you haven't measured it, is it too much to ask of you to download and install these programs to check it yourselves?

Any help would be greatly appreciated. Thanks in advance.

Reboot again with clean boot. Install first the ASUS supplied audio driver and then install the software. Last edited by sphinx64; at AM. Man I could have used those tools back when I first installed Windows My audio was a mess. Think I'll try these things out. Going to gradually change these things back and observe any latency changes. There's a definite change from when I first ran LatencyMon though. Its cut down now to my DPC results looking relatively low tcpip.

DPC Latency Checker looks far less happy though. Going to start re-installing things and turning things back on and watch for changes. Last edited by BaneSilvermoon; at AM.

It is more modern. They appear to have had quality control on only models of laptop and literally no other devices. From an administrative command prompt, sc delete nhi then do. Note this is what your device manager should look like. You should have a TB utility in the tray. I was able to hotplug, switch ports, and even do audio capture through the USB controller in the GPU dock with the FocusRite i2i a miserable, terrible device that is extremely temperamental… but otherwise has great audio circuit guts.

If there is the slightest problem with your USB, you can hear it. Not the best, but fine for real-time audio applications in a fairly well-configured Threadripper X.

Thunderbolt (Compatible) on my AMD Ryzen or Threadripper sysem!?

Do you have that Designare motherboard, or anybody else has? I would like to buy it, and so any info about it is welcome.

Especially info related to VFIO. I just got it, been shooting the video so far it is very nice. Exactly, I also very like that it has the TB board, which make this board actually cost close to entry-level boards, plus I heard that on gigabyte boards you can select boot GPU.

Any info is welcome. If you try GB which is what I am shooting forI would also very happy to know which kits work. It looks like GB is still not that out of box as one could hope. Cooler is another thing that is problematic on TR3. I can also buy an air cooler, either that noctua one, or the wrath ripper, assuming that they cool the cpu good enough. Thanks for the guide Wendell! Can you provide your steps of installation? Did you install the provided gigabyte ridge thunderbolt software or did you only use the legacy download?

I would love for a step by step guide. I only used the legacy drivers. Following the steps above and no installing the dch driver should get you to where you want to be.Windows 10 Forums.
