$14: bootable CD/USB
version, delivered via email
The Deluxe package includes
the Windows native Pro version. It adds a 64-bit version of
MemTest that runs directly from a bootable CD or USB drive without loading your OS first.
This version can be run on any PC that supports CSM/legacy BIOS boot, and does not require any sort of
installation. Plus, since it does not load an OS, it can directly access and
test all of your RAM. This is a great disk for computer technicians. It also
uses the rate that memory is checked as a basic speed benchmark. This can be
useful if you are trying different BIOS settings. Not only will MemTest tell
you if your RAM is still stable, but it will also indicate if the tweaks you
have made improve RAM performance.
The Deluxe version is delivered
electronically via email. We provide instructions for writing
it to CD or a usb stick.
