I wouldn't count on AM5 necessarily being as long-lasting as AM4. AMD made AM4 last as long as it did because they were coming from Bulldozer and they needed to provide a value-add, one of which was "you won't have to replace your motherboard every two generations" the way Intel does it. Heck, they even tried to bisect AM4 at the A520 / B550 / X570 mark, if only public pressure hadn't gotten them to back down. If you mean waiting six months, or one more release cycle from Zen 4, then yeah it'll probably be fine, but just not that AM5 is going to stay with us for... five generations.

repiv posted:Is the DAC/Amp powered by the USB input? Could be dirty power if so I imagine if you are the type of person that knows that that means, you likely won't be using the DAC and AMP (which are the same ICs as would normally be integrated onto the board, a Realtek 4050 and ESS Sabre 9260Q) anyway tbh.

oh my b!!! In other news, it does look like the ProArt X670E has a 10gig Marvell NIC. But the leaked prices for all these ASUS boards are all fuckin' insane, so I guess we will have to see if any of this is even worth considering.

So six months ago I complained in this thread about getting a pair of Arctic 280mm CLC coolers that could not at all cool a 5900x. Arctic coolers are not really sealed in box, their bags are open. So Amazon being Amazon (though directly sold by arctic, probably amazon’s warehouse) and having good return policies but poor testing of returned product, I wonder if I just happened upon two that had this issue: https://www.youtube.com/watch?v=jHdEqWpexH0 My 5800x3d build has a Lian li Galahad that is another one that GN recommends.

Cygni posted:I guess my question in general is... why... do we need an X670E ITX board? I guess thats a lot of fast USB which is nice, but yeah. Because lots of PC enthusiasts are idiots who want the "high-end" thing, even if the difference between an X670 and a B650 will be a non-factor in the ITX form-factor. I mean Asus is also gonna be selling a X670E mobo for $1500, so like "why do we need ____" is a question you can ask a whole lot about Asus. The answer is that if you have a ton of money and not much brains, they're happy to help correct that ratio.

Cygni posted:The Gene is back! Also the ITX board is insanely complex. The naming is confusing, so to reiterate: regular X670 and X670E are both dual-die chipsets. The only difference between those two is the level of features supported. There's a requirement for a certain level of PCIe 5 support that enables you to use the X670E label. B650 is the single-die variant. Packing in a separate dac/amp is a funny idea because those are almost universally going to be superior to onboard solutions anyway, but it's a completely useless accessory if you already have one.

I guess i just assumed the layout based on the rumors, and the official slides didn't actually state what the hell was going on, lol. This whole thing is kind of a mess, honestly.

Like "Columbus discovered America, and was friends with the Indians, and the Pilgrims came and they were friends too, and they had Thanksgivings and everything was great!" they teach you in 3rd grade History class. To ruin the joke: In a "normal" undergrad circuits class when you first encounter capacitors and inductors in circuits you are told to analyze something "under DC conditions". That means that the capacitor is an open circuit and the inductor is a short circuit. When "fully charged" both reactive components do basically behave that way. When you move on to what happens when conditions change you say the capacitor will provide whatever current is necessary to prevent an instantaneous change in voltage and an inductor will provide whatever voltage is necessary to prevent an instantaneous change in current. Other lies embedded in this are that capacitors do not have a polarity and, well, look at the normal model of a "real" capacitor:  Actual capacitors have a tendency to not behave anything like ideal capacitors and gently caress analog circuits seriously this is why I write embedded software

repiv posted:Is the DAC/Amp powered by the USB input? Could be dirty power if so So yeah, I've been going nuts over stupid interference in my equipment for multiple decades now trying to balance some convenience with quality, budget, and my personal sanity. I don't want to be that nutso with the $1k+ power conditioner but given how lovely the power lines in my house are (I have BX wiring and cloth in the walls and until the last owner there were some knob and tube circuits) I may be sorta forced to. Or move. Yeah, that's sounding like the right call given how much I've dumped into this house. Edit: also, I don't know what the point of lying to kids to idealize circuit components is. It's not like there's a political motive... or is there?

Newtonian gravity is a good comp. Generally, actual space missions are done with newtonian physics rather than relativity, because the little errors you make count far more than the difference in models. Similarly, if all electrical engineering were done by the actual physics, approximately no things ever would have been designed. You do engineering with the level of precision necessary.

I don't feel the upgrade bug right now and i'm not really in the market for a new "real" computer since I expect a 3900x to be enough CPU grunt for at least 5 more years of webshit, I just want a Mendocino system to play with even if it's one of those bespoke tinyboxes to see how much better/worse it is at gaming than my Athlon 3000g

The instant you do a lab with a capacitor in EE you learn that they’re actually polarized. This probably does not inspire confidence in what we’re learningVostokProgram posted:It's not a lie, it's a simplification to help build understanding.

I long ago wrote off the physics behind computing as "magic". Somewhere around the time where I learned things aren't just "on" or "off" but a spectrum.

Still, it’s a bit of a surprise after doing labs with resistors that generally behave as expected until you melt them.

The most goofy thing about ceramic caps that for some reason they don't teach right away is that applying a DC bias drops the capacitance below the nominal value and that this curve depends on package size etc so you really have to look at the datasheet.

Same, I want to know but where do you even start. I always wanted to understand logic gates, like really understand how that actually works. I want to be able to visualize a logic gate and be all "oh yeah electron shoots down there makes perfect sense how that does all math if you have enough of them" but I just.... Don't. I don't understand it and don't know how hard it would be to understand/where to even go to understand that stuff. Maybe it's not even hard but I am really not a math person.

I’m 100% certain that 90% of the people in my semiconductor physics classes didn’t actually know what the stuff was for. Like they tried to dive right in to saturation and calculations but at a basic level didn’t know what a transistor was used for even after passing the class

Hell physics may have been a prereq. It seemed very strange.

It seemed very strange. Yep. Right at the end of my second semiconductor physics class they switched to “ok so this thing that you’ve been staring at all quarter is just a switch with these inputs, now hook it up like this to form a nand gate, now use it in this circuit”. I’m very certain people would have had a much easier time had everything been done in reverse. And its not like all computer touched jobs require that specific knowledge so leading off with a “here is a dumb idealized version of this concept” wouldn’t have hurt anything WhyteRyce fucked around with this message at 07:10 on Aug 25, 2022 |

 This is the book that let me finally get how (late 1970s CMOS, but the fundamentals haven't changed yet) transistors work. I already understood Boolean logic, and logic gates are just truth tables embodied in circuitry, so grokking transistors was the key for me to understanding how you get from voltages to software. Conceptually, of course; I am not a CompE. I don't think there's anything magical about this book. It just has really clear diagrams and takes a very stepwise approach to explaining things. It seems to be a little scarce these days, so if anyone has a more accessible resource, please do share. Also, yeah, it was published under the Radio Shack banner, but it was actually written by staff at TI. Radio Shack was taken a lot more seriously back in 1978.

It's definitely related to the motherboard because my MacBook Pro doesn't have any of the issues while two different motherboards on different platforms (my old X570 Asus WS board and this B660m board) have had substantially different noise characteristics. But AMD's said they're trying to have AM5 last a fairly long time at least so maybe it's worth grabbing early on and stretching out the board's life? You likely have a ground loop somewhere. You can get a USB ground loop isolator or save the money and just tape over the ground pin on your usb cable. e: assuming your device is already powered and you don't need the 5v e2: come to think of it, even if it does you could put a resistor and a cap inline with the ground pin and fix it that way Dr. Fishopolis fucked around with this message at 16:00 on Aug 25, 2022 |

This might sound silly, but make sure you don't have any powerbricks close to the DAC, usb cable or the headphone cable. I had noise for the longest time and thought it was motherboard related, until I started moving things around, turns out it was a powerbrick from my monitor being too close to my xlr cable.
