    Dell Parts Catalog Does one exist?

    Never had to sign a NDA, Dell at least back then wasn't really tight lipped about their internal tech software. I had it for a number of years after that job ended, but it suffered bronze rot by the time I had discovered it years later and it was dead and gone at that point, it got tossed years...

    Dell Parts Catalog Does one exist?

    Specific part numbers are usually only available to Dell service techs, but with a bit of searching, you can find the right screen. I was a Dell service sub back in 2007-2008 and was given a CD of Dell tech only software that had parts catalogs for the Optiplex GX series we were working on for...

    Nine WiFi routers used by millions were vulnerable to 226 flaws

    If the manufacturer even provides them. In many cases, when devices fall out of their support period, or turn into a trash fire, the manufacturer dumps them and pretends the device in question never existed. Linksys has done this for hundreds of their devices, they won't even give you download...

    Flash Thumbdrive with Performance Rivaling SSD?

    Even stuff that is sold and shipped by Amazon is subject to counterfeiting. Like the MS Office "sold and shipped by Amazon" was a xerox.

    Can't find replacement Noctua fan (noice reduction)

    Overloading cheap wall warts is like playing Russian Roulette, you never know when it will explode. Some supplies will cut out if overloaded, but some will keep trying to restart and end up sending nasty voltage spikes on the output. Some will just explode or burn from not having any sanity...

    acid vapor kills hard drives

    I had something similar. Had a gallon jug of bleach up in the attic back in the 90s for cleaning out the evap coil once. Forgot about it for 30 years, went up there some months ago and saw a perfectly shaped white mound next to the jug and the jug was empty. Turns out the jug had dry rotted a...

    Flash Thumbdrive with Performance Rivaling SSD?

    Yep, they can, and usually are. Amazon is the counterfeit capital of the world, I avoid them like the plague because I've been burned far too many times by counterfeit or bait and switch garbage from them. All Amazon cares about is their cut of the sale profits, it's no skin off their back if a...

    acid vapor kills hard drives

    If by "TCA" you mean C2HCl3O2, not sure what you'd expect to happen storing sensitive electronics next to highly corrosive acid. A thin plastic bag wouldn't have done anything to stop it, the destroyed seal on the TCA container tells you that much.

    Can't find replacement Noctua fan (noice reduction)

    You mean in parallel. If you put the fans in series, they'd get the voltage of the source divided by the number of fans and probably not work. Two fans would give you 6v, 3 fans would give you 4v, 4 would give you 3v, etc. Not sure what size barrel connector that is, but there are splitters...

    Can't find replacement Noctua fan (noice reduction)

    The fan on the motherboard looks like a standard 37mm fan. They aren't really made by DIY companies like Noctua though, but you can get generic ones if the fan is failing. There are other sizes of this fan, but it looks to be 37mm. The fan is attached to...

    Nvidia’s GeForce Now has been quietly capping its founders’ frame rates

    Not at all surprising. Mega corporations have been pushing the boundaries on just how anti-consumer they can be for profit for a long time now. Ever since the explosion of SaaS, software companies have been jacking up the prices to see how much they can squeeze out of consumers before they...

    Apple announces Self Service Repair

    With how difficult manufacturers are making it to repair devices, in many cases, whole assemblies need to be replaced. Like the Surface Pro has the digitizer glued to the LCD panel, you can't change one without changing the other and it makes it hideously expensive. So if you cracked the...

    Windows 11 Will Soon Block All Default Browser Workarounds

    It's not only the stock holders that get more, it's the techs that have to keep the garbage running. Windows 10 has steadily increased my work over time as it has gotten less and less stable with the gross mismanagement it has had, and Windows 11 looks to continue that tradition with Microsoft...

    Best 4-8 slot motherboard for gaming and mining

    Of course it can be done, but it is exceedingly impractical, and you make extensive sacrifices to be able to have both in one machine. It's like building a car that is also a plane, it can be done, but it will not do either well. The ASRock H110 Pro BTC+ is a perfect example of that. It uses...

    Best 4-8 slot motherboard for gaming and mining

    There's a Cryptocurrency section for asking questions like that. And unless you're just casually mining, cramming 4-8 GPUs in a gaming rig isn't going to work. You'll also be paying far more than 5 grand for such a unicorn.

    5v Stand By (5vSB)

    There's sleep and there's hibernate. The former won't turn the system off, the latter will dump the contents of RAM to disk and power the computer off. Those were probably biasing resistors, and they didn't burn for no reason. If it was an Antec PSU, it was almost certainly capacitor related...

    5v Stand By (5vSB)

    If we're going by standard color codes on the Minifit Jr. ATX connector, that's wrong. To turn a power supply on, you short pin 16 to ground, PS_ON, which is green. Shorting the purple wire to ground is bad, you're shorting the +5v standby rail to ground. If you're saying shorting +5vsb to...

    Does this Work? 2x female to 1x male to run 2 power sources in parallel?

    Unless you have the packs in question, and have tested them for backfeed, never say it won't happen. I've seen all sorts of battery banks that claim to have dedicated in and out power feeds, but they were all wired up in such a way you could backfeed power into them from any port, regardless of...

    World's largest neighborhood of 3D-printed homes to break ground in Texas

    Houses like this in Austin are absolutely no surprise to me. They've been building fugly buildings in Austin for about a decade now. You have a mix of throwback 60s designs, postmodernism and McMansions. Then there's buildings clad in like squares of different materials. Bricks with corrugated...

    Intel Core i9-12900K, i7-12700K, i5-12600K Specs, Pricing & New TDP!

    Just like with pretty much every memory standards change, there will be budget boards that have slots for both standards, you just can't use them at the same time. I remember seeing one such board with both DDR4 and DDR5 slots when looking around at LGA1700 boards, but didn't take note of who...

    Beware of EVGA GPU's selling for "good prices"

    They said it came from San Francisco, so I'm assuming the shipment came in at the sea port and was shipped from there to wherever the EVGA warehouse was. It was almost certainly an inside job, or at least someone with enough access to know the port and truck manifests to be able to find the...

    Diagnostic help: Asus b550-i died mid game and can't get it to boot [SOLVED]

    Try running the 5900x with SMT off and see if the behavior changes. I've seen reports of 3xxx and 5xxx Ryzens which get unstable when SMT is enabled, including one of my customers that had a 3700x which did it.

    Noise and performance

    Without knowing the origin of the sound, it sounds like some sort of fan failure. It'd make sense performance falling off a cliff if the fan wasn't moving enough air, whatever it was cooling would overheat and thermal throttle.

    Suggestions for a pure gaming build based around a 3080 FTW3 Ultra

    Diagnostic help: Asus b550-i died mid game and can't get it to boot [SOLVED]

    Just make sure the system has good RAM and is stable when flashing. If the BIOS image gets corrupted in memory when being read from the source media, it's possible that the flasher won't catch it.

    really, really bad review score for Newegg

    Even with all of the problems Newegg has these days, I still trust them more than Amazon. Almost every purchase I've done on Amazon has had some problem. Disappearing in transit, never shipped, counterfeit goods, bait and switching, etc. And all of these items were either sold by Amazon or...

    Supermicro X9DRI-F no post or beeps

    The board I was trying to repair had mangled socket pins from a CPU being dropped sideways into the socket, it didn't have cracked BGA joints. Bought it from another [H] member already damaged for cheap just to see if I could replace the socket.

    Supermicro X9DRI-F no post or beeps

    Very sure even a multi-thousand dollar BGA rework machine wouldn't have done anything on the board I tried to replace the socket on. After the double hot air failed, I just chiseled the socket off the board since it was baked to death anyway. I got out my huge 150W matchless Hakko 551 and went...

    Suggestions for a pure gaming build based around a 3080 FTW3 Ultra

    I have a disdain for ASUS in general, but their incompetence has been put on show with their latest 500 series AMD chipset boards. Despite how long 5000 series chips have been out, many people (including myself) have still been getting NEW boards with ancient BIOS revisions that only support...

    Older video cards worth anything ?

    The Rx 200 series predates AMD's nerfing of FP performance. So if you do GPGPU tasks with your video card, older cards often outperform newer cards. This is especially the case with Nvidia where they want you to buy the far more expensive Quadro and Tesla cards for GPGPU, rather than use cheaper...

    Supermicro X9DRI-F no post or beeps

    Entirely possible the socket was damaged, but flexion of the board could have still been a contributing factor. From experience trying to remove BGA sockets from motherboards, solder cracking is very possible. Whatever solder they use under the socket is different from anywhere else on the...

    How often do you replace power supply?

    Usually what causes old PSUs to fail in catastrophic fashion is one of the capacitors going open/short/high ESR/electrically leaky, which stresses components both upstream and downstream from them that triggers the big bang and causes carnage. I've seen it happen too many times to count, but...

    Computer PSU RFI?

    The biggest source of EMI/RFI is going to be the mains plug. If the PSU doesn't have a good transient filtering stage, it's going to backfeed the mosfet switching frequencies into the mains. If it doesn't have one at all, which is common on shitty power supplies, it's going to be an RF blaster...

    AMD Rembrandt scores appearing online

    Yeah, we can only hope for good availability and more importantly, a reasonable cost. I remember when AMD APUs were cheap affordable solutions for general purpose machines. The last APU machine I built for a customer, the 5600G was like $300 alone after tax, and I was barely able to get it.

    Thousands of Playstation 5 consoles being stockpiled by Walmart

    Cool, good to see someone working at the port clarifying the issue. Can't believe an international port only has an 8-4 customs office, which is probably an hour less for lunch. So a 6.5 hour customs office with 14 hour a day operation, that's really dumb. They should be like manufacturing...

    SiFive Walks Away from Intel's Buyout Offer, Considers IPO

    Intel would probably turn them into some x86 instruction set, 14++++++ them and ship them on some lame Atom CPU. Good on them for not falling into La breas' tar pit.
