Memtest failures
I tried this with memtest+-4.20-r1 and grub2 and when I reboot and try to run the image, I get an error that /boot/memtest86plus/memtest is not found.

memtest+-5.01 worked fine with grub2

 * Hi, this is probably something to ask about on the forums or in Gentoo's support channel on IRC (. Once you determine the issue then you can come back here and let us know if our documentation is wrong, or if you had a user error. :) Kind regards, --Maffblaster (talk) 17:52, 3 June 2016 (UTC)


 * Hi . I didn't change any default settings. My guess is that the grub2 setup for 4.x is wrong. The grub2 setup for 5.x is certainly more involved than what was shown for 4.x. I was simply noting here for other users that try and fail with 4.x that 5.x was working. If you want I can open a bug, but I see no reason to start a discussion about this on either irc or the forums.

grub2 command
On my system, the grub2 config command is and not. Not sure if that is standard on all systems now, or if it is due to some use-flag I enabled at some point. If it is standard, we should update that. Johnjaylward (talk) 18:12, 3 June 2016 (UTC)


 * Noted in the article. Thanks. - dcljr (talk) 19:44, 10 February 2017 (UTC)

Wrong memtest86+ binaries
I tried to use memtest86+ with syslinux. However given 'memtest' binary doesn't work, but 'memtest.bin' works fine. In this page 'memtest' binary should be replaced by 'memtest.bin'.


 * Okay. Please make the edit to change it. --Maffblaster (talk) 16:12, 14 March 2018 (UTC)

pcmemtest
I just came across https://github.com/martinwhitaker/pcmemtest which might be of interest. I've not tried it. It claims: PCMemTest is a fork and rewrite of Memtest86+, which in turn was a fork of Memtest86. The purpose of the rewrite was to:

make the code more readable and easier to maintain make the code 64-bit clean and support UEFI boot fix failures seen when building with newer versions of GCC

In the process, a number of features of Memtest86+ that are not required for the main purpose of PCMemTest (testing the system memory) have been dropped. In particular, no attempt is made to measure the cache and main memory speed, or to identify and report the DRAM type. This should allow PCMemTest to work without modification on future hardware.

PCMemTest is based on the last public release of Memtest86+, v5.01.
