If your RAM is bad from a memtest, you should first update your motherboard's BIOS or consider buying new RAM. Memtest86 only detects physical errors in your system memory, but cannot fix any errors. You can read a description of each of the test sections here. 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. Just like with Memtest86, you'll need a working operating system like Windows, Mac, or Linux to create the bootable disc or flash drive, which can be done on a different computer than the one that needs testing.No, MemTest86 is a memory-only testing tool for x86 and Arm PCs. It might seem a bit strange that we rank this as the #3 pick, but since it's so incredibly similar to Memtest86, your best bet is to try Memtest86 followed by WMD, which operates differently, providing you with a more well-rounded set of memory tests.

Memtest86+ is available in ISO format for burning to disc or USB. We'd recommend performing a memory test with this software if you have any problems running the Memtest86 RAM test or if Memtest86 reports errors with your memory, and you'd like an excellent second opinion. Memtest86+ is a modified, and presumably more up-to-date, version of the original Memtest86 memory test program, profiled in the #1 position above.

Like these other tools, this one is entirely text-based and so might be hard to get used to for some people.
