(https://www.therecycler.com/posts/is-hp-discontinuing-hp-and-instant-ink-for-laser-printers/)German source:https://www.druckerchannel.de/artikel.php?ID=5023&t=hp_laserjet_druckerHP says that they are aware that many customers aren't able to provide the required cloud connectivity for HP+ (no internet access for printers). Because of <marketing blah> they won't offer HP+ any longer for LaserJet printers.

PC DDR5 memory latency specs - Page 1

content: I'm in the process of refreshing my now somewhat ancient PC workhorse, built in 2015...Looking at DDR5 memory I see specs like 6400 MT/s latency 30-40-40-72 and such. This leads to a bunch of questions I thought you guys here might be able to answer... Are these latencies the number of clock cycles at the max specified transaction rate? Or some standard JEDEC (e.g. 5600) rate? In other words, given two sticks at say 6000 MT/s and 7200 MT/s with the same latency cycle counts, the latter would have slightly over 1/6 lower latencies? Also, does the transaction spec take into account boundary crossing latencies for linear access, or is it the max specified transaction rate for up to one perfectly aligned page, ignoring the latency to initially switch to that page? Do all PC DDR5 sticks have the same page size?

content: Memory timings are given at stick’s rated clock frequency. Which is why they are so huge nowadays, compared to single-digit values of the past.DDR5-6400 operates at 3200 MHz. A single cycle takes 1 / 3200 Mhz = 312.5 ps. Timings 30-40-40-72 correspond to: 9.38 ns, 12.5 ns, 12.5 ns, and 22.5 ns.Yes, the one with higher rate and same timing numbers will have lower absolute latency.For the second part: I don’t know.

content: The MT/s rating is simply twice the rated clock frequency, so you won't get that many actual data transfers in practice.Dunno about row size (is "page" a new thing in DDR5, or is "row" what you really meant?) but in earlier generations most sticks seemed to stick to the maximum supported by common CPUs. That being said, AMD supported one bit longer column addresses than Intel and I recall there being DDR2 generation sticks which worked on AMD but not on Intel and they could have up to twice the capacity of common sticks. I'm sure the DDR5 DIMM spec also imposes some limit on maximum column address.
Where is the ambient temperature sensor on a Proliant DL380p G8? - Page 1

content: I scored a nice deal on a HP Proliant DL380p G8 (since I have 192GB of DDR3 LRDIMMs to use, otherwise I would have picked something newer even though $68 is hard to beat), it works well but the ambient temperature sensor reads about 20F less than the actual ambient temperature. Where is that sensor located so I can try to fix it? It's the version with 25 2.5" drive slots if that makes a difference.

content: the sea of sensors on DL380s turns into a pain. I had my fan sensor go bad, not the fans, the sensor. That was the end of that one. I then bought another G8 and that one decided whenever it wanted to just shutdown with no error logged. I switched to Dell but you cant mix the memory on Dell vs the DL380. The nice thing about the DL380s is that you can pull out the front cage and make a standalone SAS drive bay. You can make up a power cable for it pretty easily.Good luck finding that sensor.

Zooming in..... yup "KN3904".You'd think they'd use a factory calibrated sensor like an LM35. Given that it's a field replaceable part and no two transistors are alike, there should be a calibration process. That is, you can count on the slope (-2.2mV/°C) but not the starting point.

content: I have had this 1.5T drive that I got from my parents' IBM when they went to Apple. I can't remember how long ago that was maybe like 2009? I was thinking of getting a big drive and I was checking it out again. I was keeping the drive in the closet because I think Linux was saying it had an issue, and I can't recall if I had formatted it or not and it had bad sectors. Today I put on the jumper to enable Spread Spectrum Clock that I would consider not a logical solution, but maybe sort of a tolerance hedge against something. I formatted the entire drive today under windows 7 and it says there are 0 bytes in bad sectors. Looking at the smart data there are 2 concerning fields, Multi_Zone_Error_Rate 1 and also Offline_Uncorrectable 1. Should I be worried or is just one of these not a big deal?

If the disk starts with reallocating blocks, that is a reason to keep a close eye on it, if the counter rises, that's a cause for concern.The load/unload is annoying, but I don't think we ever had a disk fail to that (and we sold lots of them), in genereal, the WD Green were a solid choice. However, they were not great performance-wise, the load/unload often brought performance down, unsuitable for server applications. OK as a backup drive (this is how most of our customers used them).

content: Hi.I have a following situation - I have a PC test bench monitor (large digital signage display) with all the video inputs one can have, HDMI, DP, DVI, VGA, Composite. But VGA input is only via DVI connectors analog pins. Since I want all the input cables connected permanently, so they are always ready when I need them, I bought a simple splitter - DVI to DVI and VGA (https://www.amazon.de/gp/product/B07KXSSQFM/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1).The problem is, DVI input works only when VGA cable is also connected to a PC. It can even be a different computer. With single DVI->VGA or DVI->DVI cable everything works fine. My first guess was that the splitter has some missing grounds on the DVI input connector, but grounding all GND pins on VGA side did not help. Any ideas what signal it might be missing, ond/or how to make a terminator for vga cable, so the display thinks there is a PC connected to it?

content: One of the headline features of the new Ubuntu 24.04 LTS is seamless full disk encryption:https://ubuntu.com/blog/tpm-backed-full-disk-encryption-is-coming-to-ubuntuBut there is a complete dearth of guidance on how to get it working and plenty of frustrated attempt/resignations. Here is what worked for me.In the UEFI/BIOS there were several supporting setting that needed to be toggled.Clear the "security chip" (TPM) immediately before installing the OSSecure Boot requires additional keys:https://download.lenovo.com/pccbbs/mobiles_pdf/Enable_Secure_Boot_for_Linux_Secured-core_PCs.pdfin that case "Allow Microsoft 3rd party UEFI CA"Disabled User Presence Sensing and Security Chip "Physical Presence for Clear" (Lenovo value adds)Without those the OS would immediately ask for the recovery keys on the first reboot, before the user was able to extract them (thesnap recovery --show-keysinstruction in the installer). The TPM based FDE works nicely and saves having another password in the login process. Sadly it does require a full re-install from scratch to setup.

I guess you do this with the ohms setting and zero would be a short or other near zero number. I guess the DVM must be injecting something, and in the case of the core levels I am guessing in a lot of cases there is not enough amperage and or voltage to destroy electronics, but it isn't impossible with some weird old meter?In one case a bad firmware upgrade made something on the card output on a bus pin and it destroyed his cpu or motherboard or both. That is a rare failure, but even just crossing the rails to the bus pins could do that also.

My understanding is that A would have the compression artifacts from its encoding process, while B would have compression artifacts from its own encoding as well as compression artifacts of A that didn't get masked.I'm aware that there are "watermarking" algorithms specifically designed for that, my question is if the original compression artifacts can act as that watermark.

Aggregate bandwidth of multiple USB devices on single controller - Page 1

content: What total bandwidth would I get using multiple USB devices on a single controller?Using USB 3.0 devices on a USB 3.1 controller, I will get a total of 10Gbps (minus the usual overhead) when using at least 2 devices. And that it also applies if I use a hub capable of 10Gbps, but a 5Gbps hub would bottleneck things.Using USB 2.0 devices on a USB 3 controller, I will be limited to a total of 480 Mbps. And that using a USB 3 hub won't help as it doesn't translate the packets but just forwards them on.Are my assumptions correct? Does it depend on the exact controller chipset being used?The use case is connecting multiple USB cameras or video capture devices to a PC for machine vision.

content: I believe you are correct. The USB2 interfaces continue using USB2 all the way through. I'm less sure about the USB3.0 on USB3.1 hubs but that sounds plausible.One neat trick that I've seen used internally on laptops is that the designers will internally split the USB2 lanes from the USB3 lanes on a single port. They will use the USB2 lanes to run the keyboard/touchpad or other low speed devices and use the USB3 lanes for the internal webcam and card readers.Just a nice way to make the most of your ports.

content: I always wondered what it would be like to have a Raspberry Pi, so I got this used Odroid C1+ for $20 Canadian yesterday. It seems to generally work properly once you get passed the amp requirements. I have not done anything with the GPIO yet, so I hope it is functional.What I was doing was putting some software on it and then saving the packages and the install image so I can have it when it is not available. Of course I will forget certain things. I thought of including the 'fswebcam' command line tool, that allows you to take a picture using a webcam. So here is the proof of concept that a lower power device could be left on and save a series of frames to its sdcard. I configured the wired link manually and I can control the Odroid from ssh without keyboard or screen.So to make this work you have to set up a scheduled command using like crontab. For unknown reasons the Odroid totally freezes when using the other cheaper webcam on that desk.

timestamp: January 01, 2024, 02:54:03 am
content: Following situation: Got some nice servers at work, that have two M.2 slots available. As HPE (Hewlett Packard Enterprise) charges a hefty premium for OEM-branded SSDs, I did some homework and found out that the Samsung PM9A3 can also be bought as a standard stock version from various retailers.Difference: approx 80% less price, the HPE sticker will be missing, the firmware resp. the identification tag (important for driver selection and firmware flashing) might be a bit different, and, most important: For enterprise SSDs you normally have to get a firmware update via your OEM/assembly partner. So no download of Samsung Magician like for the consumer drives in that case.As the Samsung PM9A3 is comparatively affordable in comparison to other enterprise drives, like the Micron 7400/7450 series, or Kioxia, I am still trying to make my mind up- Micron seems to give you firmware updates freely, as would Intel (now Solidigm) also do- sadly Solidigm basically does no M.2 enterprise SSDs that can actually be bought...As one year ago there were some reports about PM9A3 with bad firmware, I am a bit concerned and try to make some homework regarding these issues, so I got the following questions:- does anyone has practical experience running Micron 7450 M.2 SSDs and their cooling needs?- Performance of Samsung 980 or 990 Pro in a server, that does virtualization? (The M.2 SSD would in this case only used for VMs that are used for testing stuff, so nothing reaaaally serious where loss of data matters)- Other tips regarding enterprise SSD manufacturers/models that are available in germany would be also appreciated, capacity should be around 1TB

External power supply pinouts for HP Envy laptop? - Page 1

content: I sometimes use an HP Envy laptop to record SDR data overnight. The AC power adapter is way too RF-noisy, so I generally run it from an external 20vdc battery bank -- the one I have is called a MaxOak K2, bought from Amazon. It's worked fine. The laptop's internal battery by itself doesn't last through the night.Unfortunately I misplaced the cable to connect the battery bank to the laptop, and the U.S. MaxOak people said they didn't have one available. It appeared that the HP laptop takes a 4.5mm x 3.0 mm barrel connector, sometimes called a "blue tip". I ordered what seemed like a generic replacement from Amazon.Checking the HP-provided AC power adapter with a meter, there's 20vdc between the center pin and the outer barrel surface, and also 20vdc between the inner barrel surface and the outer barrel surface.Checking the generic cable I just bought, the center pin goes to a blue wire, the outer barrel goes to a black wire, and the inner barrel goes to a white wire.I'm inclined to connect +20vdc from the battery bank to the blue wire (center pin) and -vdc to the black wire (outer barrel), leaving the white wire (inner barrel) disconnected.Does this sound best? Does a laptop want or need to sense voltage from the inner barrel for any reason?

PSU for that notebook was rated 65W, the dock was rated 90W- and somehow someone plugged in a 65W power supply in the dockingstation. Probably still would have been sufficient, but the thing did not want to turn on and showed only some LED signals.I found this, maybe helpful:https://forums.tomshardware.com/threads/hp-smart-pin-psu-is-there-a-voltage-resistance-chart.3688865/Bottom Line: HP uses the middle pin as a signal pin, probably in form of a resistance divider, to signal important values between notebook and power supply.
