A YouTube channel best known for its skillful graphics card fixes has published its first RAM module repair video. Tony from NorthWestRepair’s latest video shows his attempts to mend a pair of high-capacity DDR5 sticks worth a purported $16,000. It isn’t the repair skills that are newsworthy here. Rather, it’s the shift in economics that makes the chuck-it-and-replace-it attitude to bad RAM a philosophy that simply doesn’t apply in 2026. The impact of the AI-pocalypse means that spending a couple of hundred dollars on repair labor to save a several-thousand-dollar DDR5 DIMM is now sensible. If you can repair RAM, you can now start a business. Two DDR5 sticks were sent in to Tony, described as having physical damage. They are both ECC sticks, meant for servers, one with 128GB and the other with 256GB of DRAM ICs onboard. Tony sounded happy at the start of the video, as this is an excuse to use his Unified DDR Flasher Main Board, for which he had just acquired an RDIMM extension that works with these server sticks. Initial close physical inspection didn’t reveal any conclusive evidence of the source of the problems. So, it was hoped electrical tests would provide more clues. A data line tester didn’t highlight any issues, though. Tony used flux and hot air to reflow the solder on the first DIMM, which is a far simpler process than a reball (where all the memory ICs are taken off, cleaned, and given new solder balls). Initial signs were that the module was now working OK. So, he moved to the next DDR5 DIMM. The second DIMM “may have a faulty PMIC chip,” which is why it seemed more severely broken than the first module, Tony indicated. Powering on a system with this DIMM inserted showed no signs of life, and the DIMM didn’t even warm up (thermal camera checks). That contrasts with the first fix. Because this DIMM is completely dead, Tony did some work on the non-DRAM chips like the PMIC and SPD EEPROM first. Then he decided to reflow some other chips, including memory ICs, like before, while the board was warm. Some ICs were also reballed after inspection, making Tony suspicious of them. The repairer found a short circuit via voltage injection and thermal camera monitoring. This was fixed with a new capacitor and by fixing the short on the damaged edge of the PCB. Finally, a new PMIC chip ended the quest, and this second DDR5 DIMM powered on and trained successfully. The repair is good to see, saving these valuable components from e-waste. However, the bigger picture is that repairing memory modules could now be a viable business. Previously, it didn’t make sense to spend a hundred or two on labor to fix a DIMM that would cost about the same or even less to replace with a new one. Now the repair fee might be just a fraction of a replacement price. Get Tom's Hardware's best news and in-depth reviews, straight to your inbox.

At my job, e-waste goes into a giant box on a palette, in our loading dock. When it fills up, somebody comes and hauls it off. The condition of some machines and monitors in that bin tells me that some people are rather violent when they chuck stuff in there. Some of the machines are opened or partly dismantled, which could expose the DIMM to physical damage. I've recovered working monitors from it that were discarded simply for being old, because a bunch of identical ones were tossed all at once and most of the ones I checked tested perfectly. Unfortunately, a most of them also had blemishes on the panel, by the time I found them.

Each site sends in their surplus e-waste to the district office throughout the year. Things can range from older vga / dvi monitors to corded peripherals. Our DO tech department goes through anything with a storage drive in it to remove and retain those devices. The rest of the PC which is usually reassembled is dumped onto a pallet for tech surplus. Once the DO gets enough e-waste, they either auction it off, sell it by weight, or dispose of it as e-waste depending upon the contents of each pallet. For devices with soldered storage, they are completely wiped before being sent out to the pallets.

Many of our laptops and desktops are leased, in which case they're returned to the leasing company, rather than discarded as e-waste. My laptop was originally meant to be on a 3-year lease, but I'm now starting my 5th year on it. It could use more RAM, but otherwise is holding up alright. Reply - crypticc Hello Is closing correct or a typo? Reads really oddly to say they've trained a memory module. "Finally, a new PMIC chip ended the quest, and this second DDR5 DIMM powered on and trained successfully." Reply - bill001g I wonder what the most common failure of memory modules really is. If you lose one the actual memory chips I can't see it be real viable to replace it or swap it from another module. You likely can't get new memory chips easily since they are all likely committed to the large memory factories. Getting some random memory chip to function with the other memory chips is not very likely. There are a number of youtube video showing how these are manufactured and the system tests every chip and then groups them with other similar chips to make up a module. If you could just put random chips on a module and it works they would not have that massive testing and sorting step. It seems this guy just replaces some shorted capacitor and it magically fixed all his boards. Likely there are a lot of boards he can't fix but doesn't bother to show.

It's explained here: https://www.howtogeek.com/what-is-ddr5-memory-training/ Reply - alan.campbell99 The majority of ewaste I produce from repairs is enclosures or screens. Most major parts like the mainboards and SSDs go back to the manufacturer for repair . One manufacturer uses soldered on RAM but still uses a discrete SSD, I very rarely have to replace an SSD. Most HPs here still use SODIMMs except for the higher end models where they also go onboard RAM.Reply ``` document fetched 2026-10-06 02:55 · canonical https://tomshardware.com/pc-components/ddr5/customer-sends-two-stick-usd16-000-ddr5-memory-kit-to-repair-shop-soaring-replacement-costs-make-dimm-repairs-viable-technician-revives-dead-module-with-hot-air-reflow-and-new-pmic
