How reliable is memtest?
Could a RAM module with a memory tester still function properly even if it's not working correctly? (Performance issues occur)
It's feasible. Though uncommon, it's doable. If RAM passes memtest, I'd check other potential causes before assuming a problem exists, and then attempt to replace the RAM.
The issue with memtest lies in its limited ability to verify faults; it can only indicate that a problem exists, not pinpoint the exact cause. This means a memory spot might fail only under certain conditions. If you suspect hardware issues, the only reliable way to ensure no faults are present is to repeatedly run memtest until you feel confident oddities have had time to surface.
Memory testing can't guarantee perfect performance, but consistent results suggest it's functioning well. If it fails repeatedly, the issue is likely elsewhere. It’s usually better to check other parts like the GPU, storage, drivers, and operating system before focusing on RAM unless you suspect a specific problem with your system memory.
Memtest86+ is an excellent utility. It isn't the only one available. OCCT offers a memory test that performs well, and Cinebench will stress your RAM significantly. Naturally, the ideal method to evaluate hardware is by using it in everyday situations and observing its performance. If you notice any lag with the new RAM that didn’t exist before the upgrade and nothing else has changed, it could be connected to that issue.
