Troubleshooting a faulty RAM module?
Troubleshooting a faulty RAM module?
I already work with mobos and cpus, soon I’ll tackle gpus too. For mobos it varies—from simple cleaning to deep repairs, fixing a dirty PCIe slot or something where the board still shows bios but no display, due to a dirty connector or slot. Easy fixes are pin re-bending; hard ones are avoided. For nightmares like short circuits or blown sockets that need replacement (requires BGA rework tools), or just random failures (like VRMs burning), it’s not ideal. The boards that work are running low, so I’m cautious about replacing them unless I’m certain of the issue. For cpus, it’s usually just a quick spray of IPA or a light scratch for rust. If it’s badly damaged from impact or no clear cause, it might need more effort—sometimes it’s just a matter of luck, like a CPU that looks fine but is actually ruined. Generally, these repairs feel a bit like guessing which way the luck goes.
You can definitely clean it, but once RAM fails it stops working completely. I've never seen a CPU corrode. What are you doing to cause them to rust? A faulty GPU might also harm the board and monitor. It's better to replace it rather than try to fix it yourself.
I've noticed that some CPUs stop working after purchase. After buying many 15-775 units, three of them needed extra cleaning because of rust or buildup on the golden pads. Scraping with a needle seemed to fix it, but one E7300 was completely bad with no clear reason. If the GPU is failing badly, motherboard damage might be possible, though monitor damage seems unlikely since display cables don’t carry power. I’m thinking about checking the motherboard first and maybe using a cheaper 1155 board as a test.
Gold doesn't corrode. Perhaps someone dropped coffee or something over the board... Certainly, monitor cables carry power. How would you explain that signals reach the monitor? The card might also send conflicting signals or toggle the display on and off quickly or do whatever it wants. It's not like that—4K monitors for testing aren't widely available cheaply, nor are graphics cards easy to fix. Before attempting this, I might list it as spare parts on eBay, but it would need to be worth the effort of taking photos, making a listing, obtaining packaging, and shipping, all while risking lost packages or disappointing buyers. I'd consider it if I could get at least 200 for a broken graphics card, though that's a steep price for something so faulty.
I've never encountered a monitor failing because of the display connector, so I need some evidence to convince me. My monitor is probably an old Syncmaster from more than ten years ago with VGA and DVD inputs, so if it stops working I just get another one for $20. Maybe I should consider getting one with HDMI too, in case my Chinese HDMI adapter isn't functioning. I don't think it rusts, but some kind of plaque might stick to the CPU pads—don't know what it is, but it's probably not rusty.
I don't need that information. I wasn't saying a faulty graphics card would harm a connected screen. You'd have to ensure it won't happen and avoid any other issues, otherwise you'd have to invest in new hardware and my time before proceeding. And? If you're planning to repair graphics cards, you'll need a display and/or testing tools that are current enough to verify their functionality. That's not inexpensive.
Im not a bloody proffessional repair guy just doing this as a hobby to get some extra $ to pay for my dumb shenanigans Display is adequate, inadequate if unable to test hdmi due to hdmi adaptor not working but again these are dirt cheap because theyre just used office monitors and those are abundant And "test equipment" you mean a mobo too? Yea dirt cheap h61 will do as im not gonna be going newer than pascal or polaris Wtf do you expect this test equipment to be? You dont need stupid 4k displays or a top end mobo or even a 1600w axi just to test if something works or not
What poses a challenge is grasping the details. To fix and resell a faulty graphics card, ensure every output functions correctly and all settings operate as intended. You’ll need to confirm compatibility with various resolutions beforehand. A 4K screen with speakers meets basic requirements, but aim for one that supports higher refresh rates—ideally 60Hz or above via HDMI. If you have several affordable 4K models capable of 60Hz at least, that’s ideal. For displays exceeding 4K, an 8K option might be necessary. If you possess many budget-friendly 8K units, it could simplify the process.
Decisions rely on the GPU's VRAM capacity and performance. If a GPU functions properly, it should handle various resolutions and workloads without needing a 4K display for testing. The main constraints are VRAM size and interface limitations, likely around 1600p or higher (like 2560x1600). I don’t have deep expertise in hardware maintenance; my understanding is based on general trends similar to motherboard compatibility. In the future, when I invest in a GPU, there might be affordable options to resell if they perform well. For motherboard repairs, I already have some experience, though I’m unclear on the technical details or how components operate. I don’t currently own any desoldering tools or a BGA rework station, but I think a basic soldering setup with proper heat sources could help. Doubt exists about certain rework methods using light-based heat.
