content: I work in IT - we upgrade Windows and Mac computers.I am not an electronics expert.However, I have noticed very interesting trend.We get in old systems to upgrade to SSD. Previously, they would have been using spinning mechanical hard disks. So, it might be an Windows desktop PC or an iMac for example. The systems would be performing terribly slow. We put in a new SSD and the system is given a new lease of life. Where once the operating system and applications would run painfully slowly - after the SSD upgrade, they would run really fast.However, anywhere from 3 to 6 months later, the motherboard would just fail on these systems. Not all of them, but about 30 per cent of them.My hypothesis: It's as if the system was used to operating at a slow speed all it's life. With an SSD the electronic components get a shock, can no longer handle the speed and the motherboard fails because of overstress.Sorry for being over simplistic here. But does anybody have any theories on why this happens?(But please don't state the bleeding obvious by saying "they're old systems anyway")

content: I've converted enough (mostly laptops) systems to know that I don't have a 30% failure rate with quite a high confidence interval. Actually, I've never had one over maybe a dozen such conversions as well as custom builds. What OS ends up on these systems and how does the motherboard 'fail'? Other than the capacitor plague and an occasional physical mishap, I haven't seen many failed motherboards. Of course, I don't work on very many Apple products.

content: This particularly affects iMacs which are between 2010-2012.We will not take on any systems below 2010.The Windows systems would be typically 7-8 years. These are branded systems like HP.SSD brands we would use would be WD Blue and SanDisk. BTW, just to re-emphasize the SSDs would be fine.We often do not have time to pinpoint exact failure of motherboard.And thanks kripton for bringing up the issue of iMac 2011 - yes, this graphics chips on these seem to be a big problem.

All of the applications that I can think of that use a lot of CPU or GPU--HEVC encoding, web browsers with 100 tabs open--would not be significantly affected (powerwise) by drive performance.QuoteThat would be the place to start if nobody else has observed a similar correlation. Even if your failure rates are abnormally high compared to a baseline of unimproved systems--not a foregone conclusion b/t/w--the cause could be any number of issues.QuoteHere's a thought. Were these systems in use right up to the time of upgrade or have they been taken out of service some time back, left in a closet and now you are resurrecting them?

content: Quote from: Solares on June 12, 2021, 05:12:44 pmPerhaps it does, but William of Occam would probably side with an explanation of "machines are more likely to fail after someone has partially disassembled and reassembled them". Or as BD139 (who is on a break so isn't here to comment) would have put it "If you monkey around with systems they break".The only way to be confident that your hypothesis is true would be to do a controlled experiment. Upgrade to SSDs in some machines (group "monkey involved type S"), remove and reinstall the HDDs in some of them (group "monkey involved type H"), and leave some alone (group "no monkey involved in process"). My hypothesis is that you would see higher failure rates in both the groups with "monkey involved" and normal failure rates in the "no monkey involved in process" group. Of course thisallfalls apart if your sample size is too small compared to the normal failure rates of machines anyway - as is probably already be the case for your anecdotal analysis. You'd need thousands of machines to get a reliable result in a reasonable period of time.

And some are very good at it!So, what if they had been in storage?And thanks Cerebus for your comment the hard disk upgrade process is actually a very unobtrusive procedure. For example, with old iMacs, it just a case of removing glass screen, disconnecting the screen and power connector to the LCD and then have direct access to the disk bay. No need to remove or alter any other components.

content: Hmmm, I really doubt it. There are good motherboards, and crummy ones. I have been using used Dell Optiplex systems from eBay for well over a decade. I have one on my web server, one on my main desktop, and a few others here and there. Most have SSDs in them, and have been running for anywhere from15 years down to just a few years. Other that one where I blew up the parallel port with a 12V wire touching, none of them have died. I have seen a few power supplies go bad.The Optiplex is Dell's commercial line of computers. If you look inside one, you can't SEE anything that looks different from their consumer line, but there IS something different about them. This machine I'm typing on was bought used and has been running for 9 years straight. I just replaced the SSD as I was afraid it was going to suffer the "wear out" problem sometime, and also I needed a bigger one.Dell did get hit with the capacitor plague about 15 years ago, and that did cause a lot of motherboards to crap out.Jon

content: Aren't Macs of that era known for having BGA soldering issues? I suspect if there is any cause-effect relation going on here, it's that simply disturbing an old system internally and putting some mechanical stress on the board (plugging/unplugging cables) is causing cracks in already weak solder joints that results in a failure after some number of thermal cycles. There is no reason that a faster disk would make the motherboard fail.

ESD damage is the most likely, but could also be things like incorrect (dis)assembly, for example stressing boards incorrectly, causing damage to solder joints.

content: Quote from: Solares on June 12, 2021, 07:58:07 pmI physically moved the SSD from the motherboard's SATA2 Marvel controller to the JMicron controller, but I think the Intel controller would have worked just as well. The same SSDs have had no issues on new SATA2 systems.The problem took more than a year to resolve. The symptom was simply black screen computer crashes, which were eventually daily, with no diagnostic information coming from Windows, but it finally generated a blue screen which mentioned something about the page file. Further investigation showed that the SSD was accumulating UDMA errors which is an interface problem. What was going on is that page-in operations were failing not with corrupted data but unavailable data, which obviously causes the operating system to become extremely unhappy. Each crash took time to manifest because paging operations increase as the memory load increases over time.The above was not the only thing I changed to attempt to fix the problem. Originally I thought the crash was caused by hyperthreading because the original blue screen error had to do with interprocessor communications and disabling HT stopped the crashes for months. Now however I have been able to enable HT and have not had a single problem since moving the SSD.

Treat any research in any of these areas with utmost scepticism. When people do good, unbiased research in these fields and produce valid results that other people don't like it can go badly for them - see what happened to Professor David Nutt, a former government drugs adviser who was sacked when is research findings didn't support the government's position.

content: Motherboards don't fail from "hard use". In general motherboards rarely fail, a 30% failure rate on motherboards that are 5-10 years old is astonishing, and pretty much an indication that you are damaging them.There are a few options but my money is on overheating. This could happen a couple ways. You could unplug a case fan either accidentally or deliberately and forget to plug it back in. If you try to clean the years of accumulated dust out of the case you could be actually damaging a fan causing it to fail within a few weeks and overheat. Blowing around dust with compressed air can drive more dust into a bearing. Or you could rearrange things in a way that that obstructs airflow. When you get a failure look to see if any fans are stopped, too slow, or show abnormal friction when off.It could also easily be mechanical damage or ESD. Or it could be something else entirely. Since you haven't given details of the symptoms it could even be that the motherboard is fine, something other hardware or software is the problem.

content: I had a recent crypto mining adventure that used of SSDs and ran them flat out for days moving about 30 TB of data in a day.SSDs can consume a considerable amount of power indeed, but its still less than a HDD. An actively working SSD does consume more than a idle HDD (laptop drives typically reduce RPM when under low utilization), but when a HDD is actively working it consumes more power than a actively working SSD. Still these powers are in the order of a few watts, so its not going to really break anything.What i have noticed however is that hammering a bunch of SATA SSDs full on did make the southbridge run noticeably more toasty (This is where the SATA comes from) so i added a fan to help cool it.Modern SSDs can indeed saturate a PCIe link because they typically only use up to a PCIe 4x link. Yes GPUs can transfer even more data since they have a PCIe x16 link while they indeed don't usually make use of all of it, the trick to making the GPU hog all of it is to let it run out of VRAM, this will make it start swapping into main RAM and clog that x16 link. But this is unlikely to make something overheat, if anything a big GPU itself would cook things to death before the PCIe power use would, the PCIe lines go straight to the CPU anyway. However... there are also chipsets out there that provide extra PCIe lanes from the southbridge chip, these are typically used for any extra onboard peripherals such as perhaps a fancy high performance network interface, WiFi, extra SATA controllers, and M.2 slots. So in this way a M.2 NVME SSD could put extra thermal load into the southbridge chip.An SSD will also rise the peak CPU utilization since during boot the OS is spending much less time waiting for data to arrive from disk and much more time actually processing the data it just read. But a laptop should not die just because the CPU utilization hits 100% every so often. That's like a cars engine breaking down if you floor the gas pedal for a little bit too many times. But yeah holding 100% CPU utilization on a laptop tends to not be good for them since they typically don't have enough cooling to handle it unless you live in Antarctica. But this is not something a SSD would do.I don't really think this is the cause of the machines giving up the ghost. Its likely just that they die from old age. All the machines you happened to upgrade ware likely machines that got used a lot (hence why they ended up upgraded) and they just slowly died on there own. A lot of apple laptop models are famous to just die after a certain number of years due to the soldering giving up.

Could be just a particular connector getting lose from vibrations and shorting the whole thing to death.It is well known fact that Macbook solder is known to crack. But 3-4 months with 30% failure rate is surprising. I've never seen such high failure rates even with shittiest of any computer shop.What failure mode BTW.

content: Such things can easily happen even to the big guys.For example Microsoft had one hell of a situation with the early generations of Xbox 360 consoles. They made the console considerably more compact compared to the previous generation, while packing in lots of processing power. As a result it ran pretty hot and the thermal cycling eventually cracked solder balls on a lot of them causing the famous "Red ring of death" error after a year or two of regular use(sometimes even weeks or months). This was not a small percentage of units either, it happened to a lot of them.It cost them huge amounts of money to replace units under warranty. Microsoft never officially released what caused the issue but sources say that part of the problem was using the wrong lead free solder alloy that was particularly prone to cracking under these hot conditions. Some point at Microsoft sticking there fingers into the graphics ASIC design too much and causing it to run hotter than it should.Then again there are also plenty of laptops that run very hot but don't have reliability issues. Just that with MacBooks there is a lot of them out there, so its easier to draw some statistics on there reliability.

Even though temperature needed to restore the operation was much lower than solder melting point.

This would actually help, but only for some time before it would die again.I don't think Microsoft actually attempted to fix the failed boards, they likely just ripped out the old boards, threw a few truckloads of them into a landfill and put in the brand new revision boards that didn't have this problem.Cracks in the BGA balls do still happen sometimes (Even tho most cases are actually the microballs on the die, as those see more stress). One of the changes on the new revision 360 motherboards was added glue. You often also see under fill glue on BGAs in iPhones and similar products, its not strictly necessary but it seams they found it does provide a meaningful reliability improvement (mechanical and keeping dirt out) to be worth it.

content: My guess is that, given that those are exactly the models affected by some GPU solder (or bumps) failures, that the forces involved during SSD installation (such as when removing and inserting connectors) flex the board just enough for further weaken the already iffy solder joints/bumps, such that subsequent thermal cycling causes them to fail.Again, this is easily tested: do the same process as for installing the SSD, butreinstall the original parts. That wouldconclusivelyreveal whether it’s thepartor the installationprocessthat’s causing the subsequent failures.

Heck, in some aspects, lead-free solder has superior characteristics, so it’s possible that those have actually negated the negative aspects in real-world products.Look athttps://www.fujitsu.com/global/documents/about/resources/publications/fstj/archives/vol38-1/paper14.pdf

Now that I know it's desktop, I'm even more sure that the problem is mechanical.Those things had huge 3.5 inch drives.Replacing them with tiny SSD would need a mount. Maybe the Mount the you're using is bigger than what it's supposed to be and putting mechanical stresses all over the place

content: usually adapters are made to fit inside a metal drive cage in the front portion of chassis that can flex so the adapter being a bit bigger might not be a problem.But whatever...We all can go on forever, guessing what the cause could be... nothing can be said without looking at the damaged computer itself

Same goes for Asus, which is a trap company for enthusiasts.Asus puts their fans in laptop in such a way, that you'd have to remove cpu-gpu combo heatsink to get them out. Big problem when you're the service tech cleaning themHP is even worse with their fans sucking air from the gaps between keyboard keys along with user's sweat.

content: Speaking of HDD replacement, Mac and thermal issues, it reminds me of something: some iMac (2011) use proprietary HDDs with customized firmware that repurposed SATA pin #11 (activity indicator signal) as a temperature sensing PWM signal, this is used by the logic board embedded controller for thermal management. Replacing the HDD with another HDD or SSD will cause erratic thermal behavior: the logic board finds the invalid temp. and enters fallback - maximal fan speedBut this can't be the cause of OP's issue here as it increases cooling, not decreases it, but unusual enough (perhaps not for Apple) to have a mention.The workaround was simply enough... pin #11 is open-drain, so bridge it to pin #12, ground, so the controller reads a 0 but not invalid, and you're done, but at your own risk: although an SSD is unlikely to overheat (and even then, has its own throttling), it's unknown whether the controller uses the HDD temperature together with other temperature to make a decision and whether bypassing the HDD temp. sensing makes the fan management less responsive. For those particularly care about the problem, iFixit sells an upgrade kit that recreates this signal by a microcontroller.

content: To share some own experience: I also upgraded lots of PCs (mainly at work) from HDD to SSD to get some more life out of them, and this usually went well.In my experience (from about 25 years of building and repairing PCs) PCs can fail after some period of no or minimum use due to several reasons.Those include dust and dirt buildup that causes heat issues and/or attracts humidity with leakage currents, failing powersupplies that run unstable, and especially in systems that ran 24/7 for some time, minor cracks in the PCB itself or dry electrolytic caps. After getting cold, on power-on there would be some issues...But this should not amount to about 30% failure rate.Some good ideas when upgrading those old systems:- Clean for dust and dirt with compressed air- put new thermal paste between CPU and heatsink- check all fans for smooth operation- check all internal cables for tight fit- sometimes it is worth unplugging and replugging them a few times to get rid of some corrosion/oxidation- same goes sometimes for RAM modules- in earlier times where not all contacts were gold plated, the SIMM or PS/2 modules were cleaned with a eraser/rubber- blue side, if needed...Other story: A year ago, I built myself a new PC from scratch and left my old box in the corner (minus the HDD/SSDs). Two weeks ago I wanted to repurpose that machine as a Unix workstation for some fun stuff related to photography. So took out that system, cleaned it a bit, hooked the original SSD (120 GB Samsung before they were called EVO...) and tried to power on. Nothing. Some beeps pointed to memory issues.Did the whole stuff of swapping out memory, removing everything that would not be needed for initial powerup- nada.Put in a CPU from another system with the same socket 1155, and on it went like a charm.Conclusion: In about the roughly 10 months the system stood aside something happened with the CPU- a genuine Xean 1230 v3 that worked about 7 years or so without a problem...Mainboard was/is Gigabyte, one of the first models of their "Ultra Durable Series" with a H77 chipset- solid stuff, this combo worked long hours without any hiccups...

Does not take much to short out a chip in many cases, reflowing most likely melted a wisker long before the rest of the solder. Some people recomended uping the voltage to blow the wiskers away.

content: Quote from: Raj on June 28, 2021, 04:31:44 amStill way better to have a slightly crusty looking joint compared to two pins being shorted together.I think the modern alloys are better in terms of tin wiskers so it is pretty rare. Tho it doesn't necessarily need to come from the joint itself. I heard of a server room that suddenly started having the servers die at a abnormally high rate and they had no idea why, but after a while they found out that the tin plated air ducting in the server room has started growing a tin wisker fuzz on it. The airflow would eventually pick up some of these tiny tin needles and carry it into a server where it would kill it.

content: The explanation could be as simple as poor repair technique. For example, over tightening screws and causing stress damage to the PCB. If you do this consistently, then you will see a pattern that others do not see because they don't introduce that particular variable.
