content: Hello everyone.I am building a PC with a Ryzen 3600 and an Asrock motherboard. The board and processor support ecc memory. My question is will reg ecc ram run. The specs of both say non reg only. The reading i have done i am fairly sure has confirmed that it wont. But what i am not sure about is if its a case of it will work but without making use of the functionality of registered ram or if its a straight no it will not work.And the second question is if it will run are you better of running 16 gb of faster ram or 32 gb of slower ram? It would be 3200 vs 2400(i think thats the speed of the reg ecc ram)I have ordered everything else and just wanted to confirm this before i buy ram. Or buy ram.ThanksM

content: Registered ECC will not work with desktop CPUs/motherboards. You need unbuffered RAM with or without ECC. You can overclock RAM. Most of 3200 Mhz modules actually use lower tier RAM chips, often cheapest 2133 MHz grade and overclock them.

content: I would rather have slower 32GB RAM than faster 16GB.Then, 3200MHz vs 2400MHz doesn't mean much for comparing the RAM speed. Those numbers does not compare like it would be the difference in a processor speed. For RAM, the timing (CL) is often more important than the RAM clock. A 2400MHz RAM with low CL timings can be faster than a 3200MHz RAM with lots of CAS waiting cycles (bigger CL numbers).

content: Yeah dunno.It's a common GUI trend to dim whatever is behind the currently active "pop-up window" or dialog, supposedly to help the user see it more clearly/help them focus on it.I have mixed feelings about this. It does look a bit fancy at first, but can be pretty annoying. In a number of cases, it's actually even useful to be able to see what's behind the current dialog (that's also why it can be useful to also be able to move around the pop-up/dialog currently in focus.)

content: I need to develop a custom engine and I need a mounting frame like the one in the pic to install it into a common PC case.TheStartech Bracket425fkit lets you add four 2.5” SSDs or HDDs into two 5.25” front bays (so it's a 2U kit) of your computer or server, allowing you to enhance your data storage capacity.If someone happens to have one of these kits, there is a question that I would ask: is the mounting frame for the hard drives attached to the base with screws (pic1: points with a red line) to the mounting frame base? And if so, is it removable?I don't need the frame for the hard drives, I only need the mounting frame base, on the top of which I would like to install my custom board.If so, it would be perfect for my needs, but I cannot find this information from the vendor's website.theThe second question is: how long is the mounting frame base?Thanks

SPI rom Clear CMOS how does it actually work? - Page 1

content: Hi,I'm modding a board. But it's a laptop so there's no like clear cmos button. So when I make a mistake and need to reset I need to reprogram the bios. I can see some traces to PCH ( could be mistaken).How does it actually work? Does it send a serial command to the soic 8 and it clears cmos or what happens in the background. By the way it's a MX25L32xxX (mx25l3205dm2i 4mb). Checked the datasheet but don't really understand how it works, still.Removing battery for 10mins or longer doesn't work by the way. Goal is to reset to default bios nvram.Any ideas?

Just playing around. Have a not fully supported cpu in it now, it works but when loading a OS system crashes. Ordered a compatible chip. Was just testing a few things now like disabling cpu features but now sleep led indicator stays on and hdd activity led flashes. I can reprogram the spi and it works again because it resets to defaults. So Idk, is it really on the pch or ec. I see the traces from the spi rom go to the pch (true).Looked at a SuperMicro PDSBM-LN2+ board and I traced back "Clear CMOS" jumper JBT1 to Intel NH82801GR I/O controller. Hmm, I traced the wrong trace or can this be right. Could not find a pinout so can't say for sure to what pin it goes.
Enjoying a Quarantini - Raspberry Pi4 for Loungeroom to Loungeroom Video Calls - Page 1

content: Hello all,As it looks like we're going to be confined to our homes for quite some time, and then likely on and off again for periods thereafter, I started to look into building a Raspberry Pi4 project that converts my loungeroom into a video calling setup to say in face to face contact with my family and friends. I can see this being of general appeal to many who want to say in touch and find their phones less than ideal for group and room calling.Ideally the setup would do the following:Plug and play build, meaning that anyone can buy the parts and self assemble.Call to similar setups without commercial software (open source is the goal).Use the regular TV for video and audio out.A combined webcam with mic for video and audio in.Ideally running an app that has an Android and iOS version.Doesn't break the bank (~$200AUD)I've searched around online and while there seems to be people attempting this, I'm yet to come across a description of a completed and reliable setup.Current shopping list from Pi Australia comes in at $125AUD with a Pi4 (2 GB), case and power supply. The remaining budget will likely all need to go on a webcam with built-in microphone.So, my question is, have any of you clever buggers done this before and can tell me if this is a viable project?If so, what are the limitations, call quality (assuming the NBN doesn't render that point moot), and compatibility between platforms and devices?As yet I don't wish to commit to buying the Pi gear before knowing if this is to be a wild goose chase, but if there is a more-likely-than-not chance of success, I'm happy to have a crack at it and share the results.Many thanks and happy isolation!|

It's a 4X speed disc, and USB 2.0 Ithink is around 480Mb/s - that equates to about 60MB/S maximum.The PC is a 2.8GHz I5 ASUS running Windows 10 Home.What can I do to make it run faster?Thanks Simon.

content: That's a pretty old bit of kit. circa 2006. Power hungry too. Known to idle around 180W (!) if it's warm. I'd head in the direction of one of the more modern "microservers". They'll be faster, much much cheaper to run, quieter, you can leverage SSD storage and it'll probably not blow up randomly in 3 months just when you need it. Over 2 years you'll have a net return in investment just on power. Running that IBM box here will cost approx £294 a year, whereas a microserver ~£60 a year. So after 2 years you'll be up £468 on cash which is enough to buy a microserver and mitigate all the other risks. Obviously depends on your electricity cost that but running old stuff is rarely cash efficient other than capital expenditure.I have opted for the "use the shitty router at the network border that comes with the ISP" and skipped all local file storage because the cost of that is ~£24/year and doesn't take any of my time up managing it.

Is there anyone who has used these and has found a ready made cable. This is what I'm working with, also before you start telling me that there is that classic style panel mount extension, I will also add that, since this is a standard XLR shell, there are water/dust guards for it, for when there isn't anything connected.

Good luck tho when you visit them and ask "What's the password for your wifi", there is no way they remember that random jumble of letters or get one of those "There is a password?" or "The neighbors smart kid fixed my computers internet when it didn't work"

This chip is usually soldered in so you can't reseat it. If the chip is faulty, there is not much you can do because it may not be cheap to get a replacement.

The DJI software which is the single memory hog at 380Mb can't be installed onto an SDcard let alone moved. When it comes time to upgrade I have to clean up any Cache and keep it almost clean apart from that.Non removable Droid Bloatware remains the biggest PITA but stripping back and 'uninstalling' updates and preventing updates helps a lot. Samsung Music for example drops from over 80Mb back under 2Mb so go over your non essential apps. and dump them.

content: Hi all, we're looking for a freelancer to help us with a dask/s3fs project.Basically, we're looking to process big datasets (time series of vehicle data like speed, RPM, ...) from an S3 bucket. The aim is to process data (e.g. 500 MB across 1-50 files) on e.g. an EC2 instance and parse the resampled data (or summary statistics) for use in e.g. Dash (by plotly).One complexity in this is that our dataset is a non-standard binary format. We are able to produce an iterator for this, though the backend would require that dask is set up to extract the data through this iterator.We think it's probably a matter of relatively few lines of code to get this set up - but we're hoping to find somebody with experience to help get this setup in a smart, efficient and scalable way.If you're interested or know somebody, please reach out to me.

Does it have a working HDD?To transfer a file to this laptop you could either use a host that has a FDD (so you would write files from the host directly to the floppy) or try your luck using a data transfer cable. This could be done with either a laplink parallel cable or a serial null modem cable. That would require the host to also have either a parallel or a serial port.Otherwise, you will need to get a USB FDD. Keep in mind that not all formats work well with the cheap standard USB FDD drives on the market.

content: I have been on Linux a few years and was using VokoScreenRecorder which is fairly bare-bones but did the job whenever I needed to record my desktop. It has the option to overlay picture-in-picture of another source like your webcam, so I could demonstrate software and you could see me in the corner (much like you see in some of Dave's videos).Recently I was looking for a solution for my son as he wanted to record himself playing some video games and like his YouTube "idols" he also sees their head in the corner but the background is gone! There is no VokoScreenRecorder available for Windows 7... so after some searching I stumbled upon OBS: Open Broadcast Software, a multiplatform open-source free streaming/recording tool that is tremendously powerful! I can't believe I've never heard of this before!So within minutes, on his old Windows 7 machine, I configured the various sources to record (audio, video desktop and webcam) and set up a chromakey filter, we put up a blue background behind him and he was able to play video games and had his head "floating" in the corner complete with proper chroma-keying background removal (transparent). It was awesome! I went ahead and installed it on my Ubuntu machine and tried a few sample recordings and was thoroughly impressed.I'm not sure what Dave uses but I thought I'd share this in here for anyone who does this kind of thing. I'm not surprised that I missed some of these "gems"... there are lots of free open-source tools that I never heard of before.... Krita, LibreOffice, Scribus, InkScape, GIMP and a host of others that are now my main tools and never knew existed (as previously it was all Microsoft and Adobe). The cool thing is most of these are available for Windows too, and some could also be available on Mac, so it really makes it easy to switch platforms and drives home the point that it ain't necessarily the OS but the tools on it that people use that establishes their preferences.
