Confusion about capacity versus dual-channel settings. Concern about using fake RAM modules.
Confusion about capacity versus dual-channel settings. Concern about using fake RAM modules.
PC details match the label, but a RAM chip seems faulty. I ran it through Memtest86 and it kept failing, causing frequent crashes—especially in games using the Source engine like Dota 2 and Left 4 Dead 2. Those crashes happen every few minutes to an hour. GTA 4 sometimes stops working, though less often than Dota. Combat Mission Shock Force 2 had a memory-related BSOD error once after quitting, but otherwise runs smoothly. It worked well with many apps open at once—browsers, design tools, office suites—without any issues. I managed to get 81% performance on an 8 GB setup. Still, I’d prefer a replacement because of the ongoing frustration and sudden crashes during important work.
I’m considering adding another 8 GB for a total of 12 GB, but 16 GB feels too much for my needs. The other chip is fine, but I’m not sure about the impact on speed. I’ve used a laptop with just 3 GB RAM before, but I have no idea how much slower it would get.
Another concern is the quality of RAM listings online. Many brands like Samsung, Hynix, Kingston, HyperX are advertised as brand new with lifetime warranties. But reviews often raise red flags—sticker labels don’t match the actual chip, some don’t show serial numbers, and there are complaints about faulty units. I bought a secondhand Team RAM set to get clearer results, but one was defective.
Overall, I’m leaning toward buying a genuine new module if it’s reliable, to avoid more crashes and BSODs. I’d prefer something affordable compared to the new ones, even if it means a bit more money upfront. The main worry is whether the performance drop would be noticeable, especially with heavy multitasking.
You have some confusion going on up in here. Samsung is the IC that's put on a Kingston branded memory stick. Kingston purchased an agreement with Samsung to use their modules. The ICs come in different flavor "Dies" which you can call A-Die, B-Die, C-Die, D-Die and so forth. Which by the way all the 3 main manufacturers of memory ICs name their dies A,B,C, so forth. So It's SK Hynix Samsung Micron Are the 3 chip manufacturers. Now that's out of the way, just buy whatever 2x8gb set you want really. I'm using PNY which are sporting SK Hynix modules. I purchased them from best buy for 70$, online probably could find them for 50$. But you can have capacity AND performance of dual channel, which is what you should be doing.
@ShrimpBrime discussed the Memory ICs / CHIPS as typically belonging to one of the major players (SK Hynix, Samsung, Micron). The brand of the memory sticks can vary—Corsair Kingston G.Skill Mushkin Patriot ADATA Crucial (Micron), Samsung’s own chips, GEIL Thermaltake Gigabyte, etc.—similar to how different Android phones use the same chipset. The recommendation is to pair matching sets to ensure compatibility in frequency, timing, and voltage. Running mismatched components can cause problems. It’s best to replace the faulty kit with a new one, such as 16GB (8GB X2). If you need a replacement, return it via RMA; the manufacturer may ask for the full pair. Once you have a new unit, you can choose to keep or sell it.
Well, that's exactly what I mentioned in the title. Thanks for the explanation if the parts still came from those three. The warranty is a bit unclear—I think I might not have it anymore because I bought the RAMs secondhand, no packaging, just the sticks. Both of these were from 2016. It seems like a pretty bad deal, but it was the cheapest way to get the PC up and running after my wallet got burned. I might have avoided posting if I could just return it for repair. Likely, getting a replacement is the only choice left now.
