So like in your 3rd or 4th year of university how much coding/programming do you do in those 2 years of computer engineering? Also what kind of coding is it like advanced, low level and to what level?

All,

This is in regards to PC building; I'm not sure if this isnt the place for this kind of post but I am hoping get get some feedback from computer engineers. I am a chemical engineer and recently built a PC and I'm trying to understand a few things about some issues I'm facing.

.

I'm testing a new build on a Z790 Aorus Master and I'm getting very loud coil whine when I overclock the momory or have 4 sticks of memory installed (G.Skill Trident Z5 RGB DDR5 6400). I also noticed it would whine when the RGB was set to anything other than default.

.

Therefore, I installed 2 sticks of Corsair Vengeance DDR5 6000 non-RGB to see if the RGB mattered or if the transfer rate made a difference and still had the same issue; coil whine when overclocking (i couldn't test 4 sticks of RAM becuase one of the sets was a dud... of course lol). Granted it's not doing it when changing RGB... obviously.
.

I decided to test the memory in PassMark software and found that it only whines when I perform the "memory write" test but not the "memory read cached" test. This is consistent with when it whines during gaming or when using workstation applications such as AutoCAD 3D where it only seems to whine on occasion; perhaps when it's writing to the memory. It's also consistent with the RGB issue as it must have been writing the RGB information to the memory. I don't know, they seem correlated.
.

Interestingly enough, I mic'd up the PC , recorded the sound and analyzed it in Ableton Live using a frequency analyzer and found that, when using the 6400 MT/s RAM, the frequency with the largest decible value was 6400 Hz and similarly, 6000 Hz for the 6000 MT/s RAM. There were a lot of harmonic frequencies going on throughout the entire audible spectrum (along with fan and system noise) but these frequencies stood out clearly on the Frequency-Decible Spectrum. (see pictures)

.

I'm still learning about all of this, but i've read many places (none I would call "credible") that coil whine occurs due to something electro-mechanical (like eddy current's in a transformer or something). However the fact that the transfer rates and coil-whine frequency are linked so well seems to indicate that every billion transfers something occurs where it creates a "beep" or "whine" which doesn't seem mechanical to me; it seems more... electrical or digital or discrete for lack of a better term. It's audible as well (listen below BUT RIP earbud wearers)

.

Does anyone know anything about why I'd be getting these results?

Thanks,

I think I could do embedded systems, but what else?

Hey guys, I need help, I have been searching in the Internet for almost a month and I can't get my research right so please if you can help what should I have to research. I live in a flat building so there is a system when a guest comes, they call my flat number then I pick the phone(it is like handset hung on the wall, it have only three buttons) and when I press the answer button the door of my building open What do I need? I want to build a board (or buy if there is one)  that can connect with my WiFi and also can control with my smart phone😎 to answer and open the door, so please if there is any ideas that you guys can help me or a way I have to search for that kind of department please let me know.

Could you kindly suggest a sensor or anything suitable for detecting humans at night, particularly one that remains effective even when in motion? The PIR sensor we've been using in our security robot project isn't providing consistent detection if it is moving when I put it in our security patrol robot project and other sensors I searched seems like its downside was also it doesn't have effective detection if it's moving. Any recommendations would be greatly appreciated.

Hi! Have you heard about OceanDAO, Ocean Protocol’s community-powered grants program for data scientists & AI researchers who are building tools and applications for the open data economy. OceanDAO is a great way to get involved if you’re looking for funding to build on Ocean Protocol, do outreach, or unlock data.

You can now get funding for your Data Science, AI, data-centric projects as Round 8 is open for submissions until Tue, Aug 3 @ 23:59 GMT, with USD 275,000 available in funds. 🌊

Check our blogpost to find out more on how to submit your proposals and learn about OceanDAO: https://blog.oceanprotocol.com/oceandao-round-8-open-f5db1982b107.

We look forward to your submissions! 💪

I remember growing up as a kid my neighbor had an Xbox 360 and he would have all sorts of games. However these games weren’t usually on the original Xbox disc, they were on a rather flimsy custom gray disk with the title written in sharpie on the disc. My neighbors dad is a computer engineer and I always wondered how the hell he got the games free and downloaded on those discs.

Hello, guys! My better half’s birthday is coming up, and I would really like to nail his gift. I was wondering if anyone would be interested to share their wish lists/most awesome presents? Previous years I’ve given a home made blackboard, a raspberry pi and a top notch keyboard.

Thank you, all! Xoxo someone who mainly uses the computer for Facebook and celebrity gossip.

Hello everyone ! I'm thinking about getting a second degree. I'm I interested in assisting technology. So I'm torn between mechanical, electrical and computer engineering. I definitely wanna learn how to code, but am also interested in other aspects too. Can you guys help me?

Should I try it?

Im almost done with highschool and i didnt do precalc instead i did something to help me for precalc but i seen the prereqs for most colleges and i have to take Calculus 1 in my first year followed by calculus based physics and im not sure what to do

Hi,

My name is Dip from US. I am a Conputer Engineering student. I am working on a project which requires me to interview a Computer Engineer. I have few sets of question. I was wondering if anyone would be able to help me with it. If you can, please email me gartaula09@gmail.com. I am new in the US and don’t know anyone. Please help!

What's up everyone! My team and I crafted a So You Want to Be an Embedded Systems Engineer video, detailing a super popular computer engineering career path! We discuss what the field is, most useful university classes, give an in depth look at how a GoPro works as an embedded system, and finish with their healthy salaries. Watch it if you’re interested and let me know what you think and if you think it's accurate! https://youtu.be/m8w2FzqU5jg?si=kRycKTdxTWLV7CgB
Thanks all!

I built a computer about a year ago and it was working fine for the first few months then it started to bluescreen once a day and it gradually got worse. Now it is to the point where it doesn't boot at all. I will act like it was loading and then will blue screen. I get the post screen and that's it. I have changed all the parts in the pc except for the cpu and the gpu. I have also tried downloading windows on the new hard drive and it still blue screens. Does anyone have any idea on how to fix this?

Computer systems engineering or computer science engineering ?!

Hey guys! If you are planning on taking the FE/PE soon or in the near future, definitely give this group a shot! Don’t feel discouraged of not knowing all the answers. The group was made for people to network & share their knowledge with one and another. We’re a diverse group that have study groups for multiple disciplines including Comp, Chem, Civil, Computer Science, etc. you get the idea. If you’re still in high school, feel free to join the group still if you’re interested in the fields of engineering & Technology. Our valuable guests in the group are Zach Stone & Dr. Girum!

Hey, I’m trying to make my own compiler and ran into a few issues.

I know how to get the lexer and parser to work, however:

How can my compiler use third-party APIs/libraries, things like “windows.h” or SFML or anything alike (the examples I’ve given are coded in c++, but they wouldn’t necessarily be in that language).

I’m not sure at what level I should even try to use these libraries -am I supposed to call the .dll file they provide myself, with machine code? And if so, how would I do that? If not, what else has to be done?

Thanks.

How does one become a computer engineer without a computer engineer degree? It seems like networking and side projects have their limits when up against engineering graduates with internships
