content: So was it worth itFollowed Steves instructions by the numbers in the video above and got reduced latency memory timings to stick and prove stable under stress testingOld spec was 3200 CL16 Corsair Vengeance LPX finished up at a modded CL14 using the settings straight from the suggested Dram Calculator.Result is a bit over a 3% improvement on PCmark as per below and a marginal improvement on 3D mark but it is heavily weighted on the GPU. I did try running the memory at a higher clock (3400) and slower calculated timings and it failed and reverted the BIOS back to the old one. It is possible with playing I guess to make this work but it pushed the latency back to 16 again.Taking the 3+% gain and calling it done until I get to my 2400G build then there will be definite gains to be made as the RAM is shared for graphics duty.

content: That close, it could be just sampling variance on the CPU rating. The difference in the GPU is because I'm OCing the shit out of it; max 1450 sCLK & 2025 mCLK at approx 78°C by run's end. I bought the card because it is well-known to OC as high as 1500/2200 with "stock" cooler. It'll start to throttle at ~82°C after 10 minutes or so of furMark, but typical gaming loads it stays mid-70s.https://www.techspot.com/downloads/5462-furmark.htmlBut alas, it is a "mere" Polaris chipset; that shit is SO last year.Post a AIDA64 run; let's see your throughput vs CPU clock vs overall latency.http://download.aida64.com/aida64extreme600.exeThe full battery of tests in one panel is under "Tools" in the upper right tab."Wrong" driver in my case is because I'm running the Adrenalin 2019 driver set; it's still "optional", so not approved stable, I guess.mnem
Dead System -- PSU or MB? - Page 1

timestamp: August 15, 2019, 11:56:14 pm
content: I've got a system built with an Asus X79-Deluxe motherboard and a Seasonic Platinum PSU. It has an Intel Core i7, 64 GB of DDR3 RAM, and a Samsung SSD as the C: drive.I left the system running overnight last Saturday and when I went to use it Sunday afternoon it appeared to be powered off. The power switch on the computer's case had no effect--the fans didn't start spinning and there was no output on either of the two monitors. I verified that the wall outlet it was plugged into had power (it did).I disconnected all external peripherals (monitors, keyboard, mouse, Ethernet, and speaker) and tried again. Still nothing.I opened the case up and noticed that the power button on the motherboard itself was lit (as was the reset button next to it). This indicated that the system was getting some power from the PSU. I tried pressing the power switch on the motherboard and that didn't have any effect. I next tried resetting the CMOS (by holding down the "reset CMOS" button on the MB while pressing the power switch, but that had no effect either.Is this issue likely to be a power supply issue or a motherboard issue? Unfortunately, I don't have a spare PSU lying around that I can try. I'm hoping that it's the PSU, though, as that would be much easier to replace than the motherboard.

content: Try unplug the PSU from the motherboard and then force the PSU to 'on' state by shorting the PS_ON pin to GND. (the PS_ON wire is usually green).If it wont turn on (spin up fans) then the PSU is dead.If it turns on then then the issue is your MB not telling the PSU to turn on. This could be a dead MB but could also be that one of the many voltages from the PSU is missing or bad.Also check the PSU 5V VSB rail and make sure it's 5V under load.This rail should be present even when the psu is off and if it dies the motherboard wont have the power to turn the PSU on.

When stores in the mall sold Atari (400 and 800) and PC games, I saw them re-wrap the returned stuff with shrink wrapping to reseal the box.I know stores like Walmart, Home Depot, etc., all require the return stuff in "resalable condition" so they could rewrap and resale it just the same. It is easy to spot an old and used facet when return as new. It is a lot harder to spot a CPU as an older one unless they are trained what to look for. The tiny print-on number on the chip doesn't always correspond to the model number printed on the box/blister-pack.These days, (from sale staff remarks/comments in the mall) there is a trend around major dates of the year that people buy nice clothing for holiday events then returned it after. Sign of wear is acceptable since you have to put it on to see if it fits well. But buying with the intend of wearing it for dinner and returning for money back after dinner is not good. There is some level of lost of character with some.

There is a new release of Ubuntu, if possible upgrade to that, though some may claim messing around with that is bound to be more likely to break a system, I use Arch Linux where I pretty much update the kernel whenever I update the system.Start doing some basic steps. Reinstall both browsers. Install a quick Ubuntu environment on a VM (virt-manager+libvirt+qemu+kvm is a good solution) and install both browsers. Does it work?If all else fails, and you can't figure out why things are still crashing, then back up your home directory (preferably the entire environment if you have the space/time), reinstall Ubuntu, and then replace your home directory in the clean install with the one from the old one (saving 99% of user settings and files).

Alternatives to VMware ESXi baremetal hypervisor - Page 1

content: I realise I can Google for a list, but I'd like to hear what you guys run and your personal thoughts. I'm currently running ESXi on actual server hardware at home. Over the years I've found it to be generally quite good, but it can be a bit flakey and have some weird issues. So much so, I had to blow away an entire installation about 4 months ago and completely reinstall ESXi.The latest of those issues is following an update (to patch some Intel CPU vulnerabilities); Machines have all of a sudden started to behave oddly. Sometimes machines won't communicate on the network, sometimes they do, other times VMs fail to start or stop (sitting there indefinitely in some weird "neither started nor stopped" state) until I rebooted the entire hypervisor. Even the CLI commands to force a machine to stop don't work.These issues don't just occur with a particular VM, it changes and I know it's not the VM itself as they haven't changed at all.I can't have this kind of weirdness happening on my home network, particularly because one of the VM's is my gateway machine.What do you guys recommend as free alternatives to VMware ESXi? It needs to be able to run Windows, Linux and FreeBSD VM's and support hardware pass-through for things like NICs.

Both are perfect once main OS is loaded.And ideas?

Pretty unlikely that just the memory locations used as video memory would go bad.I suppose one thing you can try is running some 3D intensive stuff like games or benchmarks. Bad video memory can sometimes cause even worse glitched in 3D.

One of them has developed a problem - it will boot, and display a "desktop" with a list of apps, which you can scroll and click on with the touch screen (as usual), but if you click on any of the apps, nothing happens.Looks like its clearly a software problem.Is there likely to be an easy way of getting the owner's photos off this phone? I believe said photos are on the phone's internal flash, rather than a memory card.Since it boots and responds to the touch screen, I'm assuming it can't bethatfaulty, but I have never used a smart phone of any description, so I'm a bit stuck for suggestions.Any ideas? The owner has since upgraded to an iPhone, so she really just wants the photographs off it, and doesn't care about anything else.Thankssteve30

I've got an active 2m 40Gb/s one here powering the MacBook Pro, feeding two screens, a USB 3 disk, a semi-pro audio interface, a couple of USB hubs and an old Microsoft mouse all via a Belkin dock. Gets quite a bit of physical movement. No problems so far in a few months use.I suspect the difficulty getting reliable ones is that maintaining signal integrity at 40 Gb/s is not exactly easy. Some manufacturers willjustget there, under laboratory conditions, others will leave enough margin to cope with the real world too.

content: The first and most obvious question is why do you need a blower in a desktop machine.Ignoring that, using the amazing power of visual guesstimation, the height of those mounting holes seem to be about the same as the tops of the enclosure. If this enclosure is 90mm (it's slightly bigger than that), there's no way that's 80mm.The second question, is if you can build an bracket to mount it anyways, why are you worrying about what size it is?

Voltage Spikes and Noise on RPi 4B on SPI - Page 1
Forum section: electronics / general

author: rts808
author_rank: Newbie
timestamp: July 18, 2025, 11:21:57 pm
content: I have a raspberry pi 4b talking to an ADC chip. On the ADC board, I have a regulated power supply providing 24VDC to the board and have a chip stepping 24VDC to 5VDC and one from 5VDC to 3.3VDC. All the SPI traces are about 45mm long and .125mm wide. In the board picture, the front plane isn't pictured. (4 layer board with the top not pictured)1) The first issue I'm seeing are the voltage spikes. They appear to be lined up with the MISO line based off of the logic analyzer plots. Did I mess up with routing those too close together for that distance? If so, any tips or link to tips/books/websites for routing that? I'm a mechanical/aerospace engineer. I never had a circuit design course.2) I'm also seeing noise come in and out with 5.6ms of bad noise and 3ms of minimal noise. Any ideas on what the issue is? Is it my power supply chips regulating? I don't think it is since a ground plane is between them and the SPI traces. I have noticed that the minimal noise occurs up when I provide 24VDC power. When I don't provide the necessary power, the voltages look fantastic (minus the no response from the ADC chip), which makes me think I did dumb on my part with the board design.Also, how bad are ground loops between planes? I know I have some, but I thought it wouldn't be an issue.I've already learned that my desktop plasma ball shouldn't be on.

content: espeak ( sudo apt-get install espeak on most linux distros including Raspbian, atleast it was on Raspbian in 2018 ish) is good for voice synthesis, you can select things like accent as well, and modify the speed and other aspects of pronounciation via terminal flags.I've never done speech recogntion, so I'll leave that to someone else to recommend on.Where a Pi is in use, you might want to build a betetr audio circuit for it too. Atleast on the Pi 3 (maybe changed since) you can send a PWM wave out from one of the pins which, when low pass filtered, can then be amplified and be used for audio. If I remember, the Pi just outputs barely-filtered non-amplified audio from a 3.5mm jack by default, your own audio circuitry could improve the quality of this.

Power to the adapter was obtained from an unused floppy power connector.They're still widely available online.

By placing resistors you can determine the required state of the pin by just trying it (starting with your best guess based on research). And if it doesn't matter, use the best guess. Surely there has to be a compact flash specification out there... Random Google find:https://d1.amobbs.com/bbs_upload782111/files_1/armok0137124.pdf

While it only has 1 Ethernet port instead of 2, it uses the more familiar RTL8211F PHY. And it has a lot more GPIOs broken out.Wondering what you would recommend for cooling a SpacemiT K1? I suppose passive cooling with a heatsink should be fine.
