RAM compatibility tools are fine — but verify.

Yes, they work, but with one caveat: they show you what works, not always what works best.

Tools like Crucial’s scanner or Corsair’s configurator are great for checking basic compatibility — will the stick physically fit and will the motherboard boot? Usually yes. The risk is they may only recommend their own brand, and they might not reflect the latest BIOS updates or subtle timing differences.

Manual matching gives you more control and access to better deals, but you need to be precise. Google your motherboard model + “memory QVL” and cross-reference speed, voltage, and CAS latency. One wrong spec and you could get random crashes.

The real risk of using a scanner is trusting it blindly. If you buy RAM from the tool and it doesn’t work, you’re stuck with the brand’s support. If you manually match and mess up, you’re stuck with a return. Either way, a five-minute check of your motherboard’s supported memory list is all it takes.
