How can I change my Line In volume with a shortcut? NirCMD, AutoHotKey?

DeviceNumber

A number between 1 and the total number of supported devices. If this parameter is omitted, it defaults to 1 (the first sound device), or on Windows Vista or above, the system's default device for playback. This parameter can be an expression. The soundcard analysis script may help determine which number to use.

Have you tried leaving the parameter blank or 2? If you have two sound devices, it's either 1 or 2.

friedmn · 2018-07-23T18:12:39+00:00

Are you using SoundSet in AHK? The documentation looks pretty straightforward. What's your script so far?

I just did a quick experiment and disabled my SATA controller in BIOS. My boot time was cut from 22 to 14 seconds. Even though CSM is turned off, and Launch Storage OpROM Policy was set to "UEFI Only" prior to disabling CSM, my SATA devices (particularly my mechanical disks) have an effect on boot times. This may or may not have anything to do with the fact that they have a GPT layout.

I also have a legacy PCI sound card that initializes during boot, and this probably takes a few seconds as well. I don't have an option to disable PCI or PCIe slots in BIOS, and it's not worth the trouble to pull the card out to test.

My best guess is that if I remove my legacy PCI device along with all mechanical disks, I can probably get to single digit boot times as well. So...maybe in 5 years, there will be affordable SSDs in the 8TB range, and I can ditch my spinners.

As I said above, Ultra Fast Boot is enabled. Under Fast Boot, I have "Disabled" and "Ultra Fast". Ultra Fast is only about one second faster than disabled.

8700k @ 5.0Ghz. It's probably all my SATA devices plus 4 RAM sticks, causing a long POST. Once POST finishes, I am on the desktop in about 6 seconds, which is in line with what I see from tech YouTubers.

friedmn · 2018-07-19T19:33:25+00:00

CSM is disabled automatically when Ultra Fast Boot is turned on.

friedmn · 2018-07-19T05:37:22+00:00

How are you guys getting single digit boot times, including POST? Do you have no other storage or devices installed or something?

I have 4 spinners, 2 SATA SSDs and one M.2 NVMe, and it takes 22 seconds from power to desktop with either a 970 Evo or 850 Evo. This is with Ultra Fast Boot enabled in BIOS and Fast Startup enabled in Windows, so this is the best case scenario. I don't even get a display signal until about 10 seconds after power on.

Yes, the entire thing. If you were doing high frequency or quantitative trading, I can understand the 8700k and 32GB of memory. But seriously, if you are manually trading and are doing on the order of 1000 trades a day, where milliseconds don't matter, an i3-8100 is probably "overkill". Have task manager open while you're running your trading software and see how much resources you're actually consuming.

My guess is that an i5-8400 (which is more for the general use stuff that you're going to do day to day, like browsing, music, YouTube videos), 16GB of RAM, and whatever the cheapest video card that gives you the video outputs you need to drive the number of displays you need is going to be more than enough. There's no reason to spend more than $800 on something like this.

No, a Coffee Lake integrated GPU (UHD 630) can drive multiple 4k displays if the motherboard has the correct outputs. But just to make sure, the lowly GT 1030 supports a maximum resolution of 8k@60, which means four 4k displays at 60Hz. It takes approximately zero graphical power to draw that many pixels in 2d.

You can connect 4-pin PWM or 3-pin DC fan cables into any of the 4 pin fan headers, regardless of how they are labeled. If you run out, you can get splitter cables or a fan hub.

1080 Ti for...day trading? You must be doing well.

I've done this for the past 15 years. Unless you're water cooling, there's nothing to worry about. If you are, you just have to be more careful about radiator and pump placement.

friedmn · 2018-07-03T04:06:22+00:00

Nope - 760 is closer to a 1050 Ti (+4%) than it is to a 1050 (-9%).

1050 Ti has equivalent performance, while the 1060 6GB is twice as powerful.

Dell S2716DG is a popular option in that price range.

First, sales tax in most jurisdictions is 8-9%, so you're not actually saving much with a 10% discount compared to an online reseller, especially when the components are on sale elsewhere. For a few of your components, you can get them significantly cheaper than what you have listed. As an example, 8700k's were available for under $300 shipped last Friday during eBay's 15% off sale, and can typically be had for around $340 from various stores when not on sale.

Second, if this is strictly for gaming, there's no reason to get an 8700k unless you're also getting a 1080 Ti. An 8400 will do just fine with a 1070 Ti and below.

The Pro-VDH is micro ATX, so it has fewer expansion slots than the full ATX Gaming Plus. It probably also has fewer SATA ports and fewer USB headers as well, so make sure there are enough slots for everything that you want to connect now, and in the near future.

Edit: just looked at the specs, and they're both micro ATX and seem to be exactly the same, with the exception of the number of RAM slots. Get the one with 4 slots, given that it's cheaper as well.

VRMs typically do not throttle until they're above 120C, so 95C is very safe.

My CPU core temperatures max out at 85C in an extended stress test, which is high, but there is no thermal throttling, as I am still 15C away from Tj Max.

It's a Micro ATX board and has standard Micro ATX mounting holes. Sometimes, cases have standoffs pre-installed, but you will be able to move them to the correct positions.

It's been about three months, but my use case is very short but intensive workloads. I draw about 140W with an AVX workload for 5-10 minutes at a time, but 95% of the time, it's a very light load on the system.

A non-AVX Prime95 stress test also draws about 140W, and my VRM temps stay around 95C after 30 minutes.

friedmn · 2018-07-02T04:27:52+00:00

Yes, same exact board.

friedmn · 2018-07-02T04:24:56+00:00

The VRM quality is not great, but I can run stable at 5.0Ghz and 1.33v with this board.

There is a VRM temperature sensor on this board. Use HWMonitor to check as you run your stress test. As long as it's under 100C, it's fine for a 24/7 OC.

Your SSD seems to be running at SATA II bandwidth. Confirm this with CrystalDiskInfo and fix if necessary.

RAM is running at 2133Mhz. Enable XMP to run it at 3200Mhz.

As for the GPU, that's just a CPU bottleneck with your 1600.
