Everyone frightened by the title? Okay, it may be a bit exaggregated, but hear me out, this might be an interesting read for you. Have you ever heard about AM5 and DDR5 beeing unstable, expecially with more than one DIMM per Slot populated? Most likely yes, this is a quite widespread information, and basically everyone has accepted to use only one DIMM per channel, if you want to even get close to the advertiesed RAM-speed by the memory modules. But have you ever heared, EXPO profiles harming your LUKS-devices? Me neither, so here goes the story, that almost ruined my sunday…

Add memtest86+ to (U)EFI-Only Linux Environments

Maybe you have been in the need to use a memtester like memtest86+. Maybe to test Ram-Overclocking (like XMP/DOCP), stability (like „more than 2 sticks of ram on AMD AM5“), because you suspect a faulty stick, or just as burn-in-test. Maybe you also realized, that memtest86+ – for the longest time – only supports booting in legacy CSM-Mode (aka. „legacy BIOS“). While this isn’t a big deal, when you have memtest on a bootable stick on a Board with CSM-Support (which is still true for most mainboards), it can be a challenge, when the Mainboard is (U)EFI-Only, when you try to add a boot-entry from a running Linux-System, or when having no physical access, like on Servers, when you are using the respective Out-Of-Band-Management-System. Or maybe, you just want to have memtest on hand, because you regularily have the need to run it for whatever reason.
