pcmemtest 1.5-4 (amd64 binary) in ubuntu kinetic

 PCMemTest is a stand-alone memory tester for x86 and x86-64 architecture
 computers. It provides a more thorough memory check than that provided by BIOS
 memorytests.
 .
 PCMemTest can be loaded and run either directly by a PC BIOS (legacy or UEFI)
 or via an intermediate bootloader that supports the Linux 16-bit, 32-bit,
 64-bit, or EFI handover boot protocol. It should work on any Pentium class or
 later 32-bit or 64-bit CPU.
 .
 PCMemTest is a fork and rewrite of Memtest86+, which in turn was a fork of
 Memtest86.
