I recently came across a YouTube video which booted from a large dedicated USB drive to run Nvidia and AMD diagnostics using MATS (Memory Automated Test System) and MODS (Modular Diagnostic Software).
Nvidia has a proprietary software tool called MODS (Nvidia MOdular Diagnostic Software) which has a standalone VRAM test called MATS. How to use MATS can be found below.
- Here is a written guide on how to use MATS Nvidia Memory Testing Guide.
- Here is a video by MV TechLabs on How to set up and use MATS

To make a new bootable USB HDD with all three test images, see 'How to make a MODS and MATS USB drive' below.
The USB he created comprised of three separate Primary MBR partitions with each partition containing a separate set of bootable files:
- Partition 1: nVidia RTX 30xx Series And Before 5GB
- Partition 2: nVidia RTX 20xx, GTX 16xx/10xx/9xx/7xx/6xx/5xx Series And Before 5GB
- Partition 3: AMD RX4xx/RX5xx/RXVEGA64/R7/R9 Series/HD7xxx 60GB
I made a separate USB drive from the .rar files from the instructions in the video but for some reason the ext4 Partition 3 seems to be corrupt on my drive and would not boot at all :-(.
However I could legacy boot and UEFI64-boot OK to Partitions 1 and 2 of the new USB drive.
I wanted to add some sort of bootable images of these to my E2B drive so I used RMPrepUSB - File - Make grub4dos ISO file function to make a bootable ISO. However, the ISO file only worked when Legacy booting (it hung on a UEFI boot as did Ventoy).
