MemTest86 executes a series of numbered test sections to check for errors and there should be 0 errors. How many errors in Memtest86 are acceptable? Memtest86 will load your CPU up to 100% during testing, because data read or written to RAM will pass through the CPU, but it should not harm your processor or RAM.
MemTest86 boots from a USB flash drive and tests the RAM in your computer for faults using a series of comprehensive algorithms and test patterns. Should you use MemTest86+, rather than the original MemTest86? It's certainly worth a try this new edition supports many more CPUs, improves SPD and memory controller detection, and adds a few useful extras (the report includes your motherboard manufacturer and model, CPU temperature and more).No, MemTest86 is a memory-only testing tool for x86 and Arm PCs. If you see any errors, there's a problem with your hardware if you don't, your issues are probably somewhere else.
And again, there are a lot of error types which could be reported at the end of the test (MemTest86+ is very thorough and detailed), but you don't really have to understand those, either.
It's fairly technical, but if nothing else the "Pass %" and "Test %" will show you how far through the checks you are. The screen then updates to show you exactly what's going on, the various tests that are being used. A menu offers a selection of test options, but you don't even have to worry about that: just wait a few seconds and the default test pattern will begin. There's no complicated operating system which need to fire up, first - you're straight into the program's simple text-based interface. MemTest86+ boots immediately, for instance. It arrives in the form of an ISO image, so isn't quite as convenient to use as some of the competition, but once you've burned it to disc or a USB key - which won't take long, as it's a tiny 1.75MB in size - everything else works very well. MemTest86+ is a simple but thorough tool (based on the original MemTest86) which will scan your PC's RAM for errors.
